Abstract
Context: Kangfuxin (KFX) is widely used for the treatment of gastric and duodenal ulcer; however, more research is needed to determine the protective mechanisms of KFX in ameliorating gastric ulcer.Objective: To investigate the efficacy and potential mechanism of Kangfuxin liquid (KFX) in water-immersion and restraint stress (WIRS)-induced gastric ulcer.Materials and methods: Seventy rats were randomly divided into seven groups (n = 10) as follows: the control group (normal saline, i.g.), the model group (normal saline, i.g.), the KFX groups (2.5, 5 and 10 mL/kg, i.g.), the omeprazole group (20 mg/kg, i.p.) and Sanjiuweitai Granules group (1850 mg/kg, i.g.). The WIRS model was applied to induce stress ulcers after 7 days of drug administration. Afterwards, rats were sacrificed at 10 h induced by WIRS.Results: Pre-treatment with KFX (5,10 mL/kg) could effectively reduce the area of gastric ulcers and improve the pathological changes of ulcerated tissue. Moreover, KFX (5,10 mL/kg) increased the prostaglandin E2 (52%) and cyclooxygenase-1 (30%) levels, and improved malondialdehyde (54%), superoxide dismutase (58%), catalase (39%), and nitric oxide (11%) and TNF-α (9%), IL-6 (11%), MMP-9 (54%) and MMP-2 (53%) of ulcer tissue. Furthermore, pre-treatment with KFX dramatically increased IGF-1, PTEN, and Akt protein expression.Conclusions: Our results suggest that KFX has protective effects on WIRS-induced gastric ulcer via inflammatory reactions, oxidative stress inhibition, and pro-survival action, which were the results of activating the IGF-1/PTEN/Akt signalling pathway. Our results provide evidence of KFX for treating gastric ulcer.

Inhibition of microRNA-221-5p induces osteogenic differentiation by directly targeting smad3 in myeloma bone disease mesenchymal stem cells. Oncol Lett 2019; 18:6536-6544. [PMID: 31788114 PMCID: PMC6865756 DOI: 10.3892/ol.2019.10992] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Accepted: 06/14/2019] [Indexed: 01/08/2023] Open
Abstract
Myeloma bone disease (MBD) is one of the clinical features of multiple myeloma, which contributes to the attenuation of osteoblast function. Bone marrow mesenchymal stem cells exhibit a high potential for differentiation into osteoblasts. A number of studies have reported that microRNAs (miRs) serve a vital role in mesenchymal stem cell (MSC) osteogenesis; however, the role of miR-221-5p in the osteogenic differentiation of MBD-MSCs remains unclear. The present study revealed that the osteogenic differentiation capacity of MBD-MSCs was reduced compared with that of normal (N)-MSCs. Further experiments demonstrated that miR-221-5p expression was downregulated in N-MSCs following osteoblast induction while no obvious alterations in expression levels were observed in MBD-MSCs. The inhibition of miR-221-5p promoted the osteogenic differentiation of MBD-MSCs. Bioinformatics, luciferase reporter assays, reverse transcription-quantitative PCR and western blotting assays indicated that smad family member 3 (smad3) was a direct target of miR-221-5p in MBD-MSCs. A negative association was identified between the expression levels of smad3 and miR-221-5p. Investigations of the molecular mechanism indicated that suppressed miR-221-5p could regulate the osteogenic differentiation of MBD-MSCs by upregulating smad3 expression. It was also identified that the PI3K/AKT/mTOR signaling pathway was activated following miR-221-5p inhibition, and this increased the osteogenic differentiation capacity of MBD-MSCs. The present study may improve the understanding regarding the role of miR-221-5p in the regulation of osteogenic differentiation, and may contribute to the development of a novel therapy for MBD.

Abstract
Cancer is recognized as one of the most prevalent contributors to mortality in several nations and it remains one of the common health issues globally. In particular, hepatocellular carcinoma (HCC) has become a public health problem along with the increase of hepatitis B (HBV) and hepatitis C (HCV) virus infections. Based on this fact, our study goaled to synthesize newly hybrid drugs containing heterocyclic rings incorporated to steroid moiety and to examine the potential antitumor activity of the newly designed heterosteroid derivatives against HCC induced in animal model. Several heterocyclic steroids were synthesized 2-7 and confirmed via the analytical and spectral data (IR, 1H NMR13C NMR and Mass spectroscopy). Compounds 3, 4, and 5 were chosen to be investigated as anticancer agents in HCC rat model by means of validated biomarkers (alfa –fetoprotein, endoglin, lipocali-2 and heat shock protein-70). Following administration of compounds 3, 4 or 5, availability of the active tumor marker molecules was significantly dropped and a substantial decrease of the angiogenic and inflammatory mediators was also evident. These findings were supported by the histological examination of liver tissue. Taken together, this study indicates the potential anticancer activity of the newly synthesized heterosteroid derivatives against HCC in vivo. The antitumor activity of these compounds was likely attributable to modulating some signal transduction pathways involved in tumorigenesis, angiogenesis and inflammation.

Abstract
Garlic (Allium sativum L.) has been used extensively as a food ingredient and medicinally, but the effect on asthmatic airway inflammation has not been studied in detail. We accordingly explored the protective effects exerted by various garlic fraction extracts against airway inflammation with Dermatophagoides pteronyssinus (Der p)-induced allergic asthma in vivo and in vitro. Garlic extraction was realized using n-hexane, dichloromethane, ethylacetate, n-butanol, and water in sequence to obtain different fraction extracts. Mice were orally administered different fractions (80 mg/kg) daily for four weeks. The histological results showed that the water fraction could ameliorate lung-based goblet cell hyperplasia, inflammatory cell infiltration, and mucus hypersecretion. The water fraction extracts decreased IgE and IgG1, and they decreased inflammatory cells as quantified in bronchoalveolar lavage fluid (BALF); however, they increased IgG2a in serum. Moreover, the water fraction extracts increased IFN-γ and IL-12 (both constituting Th1 cytokines) in BALF, but they reduced IL-13, -4, and -5 (all constituting Th2 cytokines), and also inhibited the expression of IL-1β, IL-6, and TNF-α. The water fraction also inhibited the PI3K/Akt/NF-κB signal pathways in A549 cells. These findings suggest that water fraction extracts of garlic have a clear anti-inflammatory effect on Der p-induced allergic asthma.

Abstract
Formation of new bone by osteoblasts is mediated via the activation of signaling pathways, such as TGF-β, BMP, and Wnt. A number of transcription factors participate in the signaling cascades that are tightly regulated by other regulatory factors. Histone deacetylases (HDACs) are one such class of regulatory factors that play an essential role in influencing chromatin architecture and regulate the expression of the genes that play a role in osteoblast differentiation by the mechanism of deacetylation. Four classes of HDACs have been identified namely, class I, class II A, class II B, class III and class IV. MicroRNAs (miRNAs) are small fragments of non-coding RNAs typically 19-25 nucleotides long that target mRNAs to upregulate or downregulate gene expression at a post-transcriptional level. A number of miRNAs that target HDACs in bone have been recently reported. Hence, in this review, we elaborate on the various miRNAs that target the different classes of HDACs and impact of the same on osteogenesis.

Abstract
Background Oxyresveratrol is a major bioactive component derived from the heartwood of Artocarpus lacucha. This compound exerts several biological activities, including neuroprotective effects in vitro and in vivo. However, there is limited pharmacokinetic information on this compound, especially its distribution in neuronal tissue and its route of excretion. The aim of this study was to investigate the pharmacokinetic profiles of oxyresveratrol alone and in combination with piperine as a bioenhancer in rats. Methods Male Wistar rats were administered with oxyresveratrol 10 mg/kg, oxyresveratrol 10 mg/kg plus piperine 1 mg/kg via intravenous or oxyresveratrol 100 mg/kg, oxyresveratrol 100 mg/kg plus piperine 10 mg/kg via oral gavage. Plasma, internal organs, urine, and feces were collected. Determination of the oxyresveratrol concentration in biological samples was performed by liquid chromatography tandem mass spectrometry. Results The combination with piperine had shown a significantly higher maximum concentration in plasma approximately 1500 μg/L within 1–2 h after oral dosing, and could increase oral bioavailability of oxyresveratrol approximately 2–fold. Oxyresveratrol could widely distributed most of the internal organs with a tissue to plasma ratio of 10–100 fold within 5 min after dosing. Urinary excretion of oxyresveratrol glucuronide was the major route of excretion after administration of oxyresveratrol alone and in combination with piperine. Conclusion The addition of piperine could enhance some of the pharmacokinetic properties of oxyresveratrol via both intravenous and oral administration. This pharmacokinetic information will be useful for appropriate strategies to develop oxyresveratrol as a phytopharmaceutical product.

Abstract
Patients who suffered a traumatic brain injury (TBI) show a faster fracture healing than patients with isolated fractures. Prior studies have suggested that this process may be accelerated through the inhibition of key microRNAs. In this study, we aimed to explore the mechanisms underlying this phenomenon, with a special focus on miR-16-5p, which is markedly decreased in patients with TBI. In vitro, miR-16-5p over-expression significantly inhibited cell proliferation in MC3T3-E1 cells transfected with agomiR-16-5p. Flow cytometry analysis further demonstrated that the overexpression of miR-16-5p induced cell cycle G1/S phase arrest and apoptosis. Moreover, target prediction and luciferase reporter assay demonstrated that miR-16-5p could negatively regulate Bcl-2 and Cyclin-D1 expression. Meanwhile, Bcl-2 and Cyclin-D1 were up-regulated after osteogenic differentiation while the down-regulation of endogenous Bcl-2 and Cyclin-D suppressed the osteogenic differentiation of MC3T3-E1 cells. In vivo, PBS, agomiR-16-5p and antagomiR-16-5p were injected into fracture sites to assess any improvements in fracture healing, which further confirmed the negative effect of miR-16-5p on fracture healing. Together, these results demonstrate miR-16-5p downregulation may accelerate fracture healing by enhancing the proliferation and inhibiting the apoptosis of osteoblasts in patients with both fractures and TBI. These phenomena may be exploited in the treatment of fractures.

Abstract
Traditional medicine plays an important role in the daily lives of people living in rural parts of Ethiopia. Despite the fact that Ethiopia has a long history of using traditional medicinal plants as an alternative medicine source, there is no checklist compiling these plants used for snakebite treatment. This review collected and compiled available knowledge on and practical usage of such plants in the country. A literature review on medicinal plants used to treat snakebites was conducted from 67 journal articles, PhD dissertation and MSc theses available online. Data that summarize scientific and folk names, administration methods, plant portion used for treatment and method of preparation of recipes were organized and analyzed based on citation frequency. The summarized results revealed the presence of 184 plant species distributed among 67 families that were cited for treating snakebite in Ethiopia. In this literature search, no single study was entirely dedicated to the study of traditional medicinal plants used for the treatment of snakebite in Ethiopia. Most of the species listed as a snakebite remedy were shrubs and climbers (44%) followed by herbs (33%) and trees (23%). Fabaceae was the most predominant family with the greatest number of species, followed by Solanaceae and Vitaceae. Remedies are mainly prepared from roots and leaves, through decoctions, infusions, powders and juices. Most remedies were administered orally (69%). The six most frequently mentioned therapeutically important plants were Nicotiana tabacum, Solanum incanum, Carissa spinanrum, Calpurnia aurea, Croton macrostachyus and Cynodon dactylon. Authors reviewed the vegetal substances involved in snakebite management and their action mode. In addition to screening the biologically active ingredients and pharmacological activities of these plant materials, future studies are needed to emphasize the conservation and cultivation of important medicinal plants of the country.

Abstract
MicroRNAs (mRNAs or miRs) serve an important role in the regulation of gene expression. In the present study, the role of miR-98-5p in bone regeneration was determined. Three osteoblast cell models were established, including primary human stem cells (BMMSC), mouse BMMSC's and MC3T3-E1 cells. miR-98-5p expression was determined using reverse transcription-quantitative (RT-q)PCR. Osteoblast markers, including alkaline phosphatase, runt related transcription factor 2 and transcription factor Sp7, were determined using RT-qPCR and western blot analysis, respectively. Alkaline phosphatase activity was determined in the present study and cell proliferation and apoptosis assays were performed. Furthermore, an association between miR-98-5p and high mobility group AT-Hook 2 (HMGA2) was revealed. This association was determined using TargetScan and a dual luciferase reporter assay. The current study demonstrated that miR-98-5p was downregulated during osteogenic differentiation and further demonstrated that HMGA2 may be a direct target of miR-98-5p. The results also demonstrated that miR-98-5p upregulation significantly inhibited the osteogenic differentiation of MC3T3-E1 cells, an effect that was reversed by an increased HMGA2 expression. Additionally, the results revealed that miR-98-5p upregulation inhibited MC3T3-E1 cell viability and induced cell apoptosis and these effects were eliminated by HMGA2 overexpression. In conclusion, miR-98-5p may prevent bone regeneration through inhibiting osteogenic differentiation and osteoblast growth by targeting HMGA2.

Abstract
During probing and blood feeding, haematophagous mosquitoes inoculate a mixture of salivary molecules into their vertebrate hosts' skin. In addition to the anti-haemostatic and immunomodulatory activities, mosquito saliva also triggers acute inflammatory reactions, especially in sensitized hosts. Here, we characterize the oedema and the cellular infiltrate following Aedes aegypti mosquito bites in the skin of sensitized and non-sensitized BALB/c mice by flow cytometry. Ae. aegypti bites induced an increased oedema in the ears of both non-sensitized and salivary gland extract- (SGE-)sensitized mice, peaking at 6 hr and 24 hr after exposure, respectively. The quantification of the total cell number in the ears revealed that the cellular recruitment was more robust in SGE-sensitized mice than in non-sensitized mice, and the histological evaluation confirmed these findings. The immunophenotyping performed by flow cytometry revealed that mosquito bites were able to produce complex changes in cell populations present in the ears of non-sensitized and SGE-sensitized mice. When compared with steady-state ears, the leucocyte populations significantly recruited to the skin after mosquito bites in non-sensitized and sensitized mice were eosinophils, neutrophils, monocytes, inflammatory monocytes, mast cells, B-cells and CD4+ T-cells, each one with its specific kinetics. The changes in the absolute number of cells suggested two cell recruitment profiles: (i) a saliva-dependent migration; and (ii) a migration dependent on the immune status of the host. These findings suggest that mosquito bites influence the skin microenvironment by inducing differential cell migration, which is dependent on the degree of host sensitization to salivary molecules.

Additional compounds and the therapeutic potential of Cnidoscolus chayamansa (McVaugh) against hepatotoxicity induced by antitubercular drugs. Biomed Pharmacother 2019; 117:109140. [PMID: 31387195 DOI: 10.1016/j.biopha.2019.109140] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 06/14/2019] [Accepted: 06/14/2019] [Indexed: 01/16/2023] Open
Abstract
Previously non-isolated compounds (scopoletin and β-D-Glucopyranoside, (1R)-O-isopropyl 6-O-(2,3,4-tri-O-acetyl-β-D-xylopyranosyl)-2,3,4-triacetate) were isolated from an organic extract of the Cnidoscolus chayamansa stem. Also, lupeol acetate (main compound, 49.7 mg/g of dry extract) and scopoletin (0.19 mg/g of dry extract) were quantified by HPLC analysis from this organic extract. The protective activity of the C. chayamansa organic extract against hepatotoxicity induced by antitubercular drugs [Rifampicin (50 mg/kg), Isoniazid (50 mg/kg), and Pyrazinamide (100 mg/kg)] are reported. The extract was tested at 200 and 400 mg/kg in Balb/C mice during 85 days, using silymarin (2.5 mg/kg) as positive control. Liver damage was determined using biochemical parameters (AST, ALT, ALP, CHOL, HDL TG, Urea, and CREA), histological analysis, and evaluation of oxidative stress (SOD, CAT, Gpx, Lpx and POx). The extract at both doses favored body weight gain with respect to the anti-TB group; the dose of 200 mg/kg was better. Also, the extract at both doses decreased the values of transaminases (AST, ALT) enzymes (p < 0.05) vs. anti-TB group. In oxidative stress parameters, the SOD value was decreased, as were the levels of peroxidation of lipids and oxidative protein in the group with C. chayamansa extract at 200 and 400 mg/kg vs. the anti-TB group. Histological analyses from liver showed the absence of steatosis in the extract group at 400 mg/kg, and moderate steatosis in the silymarin and extract (at 200 mg/kg) groups with respect to anti-TB group, which demonstrated a steatosis. It should be noted that during the study period, none of the treated mice died. In conclusion, the CHCl3: MeOH extract of C. chayamansa has a hepatoprotective effect against hepatotoxicity induced by anti-TB drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Urginea indica has been used in the traditional system of medicine to treat various inflammatory diseases. AIM OF THE STUDY Present study investigates the effects of aqueous and ethanolic extracts of U. indica on joint inflammation using different models of acute and chronic inflammation. MATERIALS AND METHODS FCA-induced arthritic rat model, a model of chronic joint inflammation, was used to evaluate the anti-arthritic effects of plant extracts (500 mg/kg, each extract). Macroscopic arthritic scoring, digital water plethysmometery, and histopathological evaluation (H & E staining) were performed to measure the severity of arthritis. Acute inflammatory models like, carrageenan-, histamine- and serotonin-induced paw edema models were used to evaluate effects of U. indica, and supported by xylene-induced ear edema model. RESULTS Both extracts significantly inhibited arthritic development, paw edema, bone erosion, pannus formation, and infiltration of inflammatory cells. Treatment with U. indica extracts resulted in almost normalization of altered counts of white blood cells (WBCs), platelets, and red blood cells (RBCs), along with Hb content. Both extracts were found safe in terms of hepatotoxicity and nephrotoxicity as determined by non-significant difference of alanine aminotransferase (ALT), aspartate transaminase (AST), urea, and creatinine levels among all groups. U. indica significantly attenuated carrageenan-induced paw edema. There are several mechanisms involved in the attenuation of carrageenan-induced paw edema; inhibition of autacoids is one of those important mechanisms. The autacoid inhibition was confirmed by reduction of histamine- and serotonin-induced paw edema found in plant extract treated groups. Suppression of xylene-induced ear edema by plant extract further validated the suggested mechanism of autacoid inhibition. GC-MS analysis showed the presence of isopropyl palmitate in the highest quantity (26.852%). CONCLUSIONS This study validated the folkloric uses of U. indica and showed that plant possessed anti-arthritic and anti-inflammatory properties which might be ascribed to inhibition of autacoids.

Abstract
Linalool is a natural product present in fruits and aromatic plants with biological activities. Researchers have reported that the inhalation of linalool exerts anti-inflammatory activities. In this study, we examined the therapeutic effects of linalool on airway inflammation and mucus overproduction in mice with allergic asthma. Oral administration of linalool significantly inhibited the levels of eosinophil numbers, Th2 cytokines and immunoglobulin E (IgE) caused by ovalbumin (OVA) exposure. Linalool exerted preventive effects against the influx of inflammatory cells and mucus hypersecretion in the lung tissues. Linalool also dose-dependently decreased the levels of inducible nitric oxide synthase (iNOS) expression and protein kinase B (AKT) activation in the lung tissues. Linalool effectively downregulated the activation of mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB) caused by OVA exposure. Furthermore, linalool exerted inhibitory effect on OVA-induced airway hyperresponsiveness (AHR). In the in vitro study, the increased secretion of MCP-1 was attenuated with linalool treatment in lipopolysaccharide (LPS)-stimulated H292 airway epithelial cells. In conclusion, linalool effectively exerts a protective role in OVA-induced airway inflammation and mucus hypersecretion, and its protective effects are closely related to the downregulation of inflammatory mediators and MAPKs/NF-κB signaling.

Abstract
MicroRNAs (miRNAs) regulate activities in living organisms through various signaling pathways and play important roles in the development and progression of osteoporosis. The balance between osteogenic and adipogenic differentiation of rBMSCs is closely related to the occurrence of osteoporosis. ERα regulates bone metabolism in various tissues. However, the correlation among ERα, miRNAs, and the differentiation of rBMSCs is still unclear. In this study, we used lentivirus transfection into rBMSCs to construct an ERα-deficient model, analyzed the differences in expressed miRNAs between control and ERα-deficient rBMSCs. The results revealed that the expression of 25 miRNAs were upregulated, 164 miRNAs were downregulated, and some of the regulated miRNAs such as miR-210-3p and miR-214-3p were related to osteogenic or adipogenic differentiation, as well as to particular signaling pathways. Next, we overexpressed miR-210-3p to evaluate its effects on the osteogenic and adipogenic differentiation of rBMSCs, and identified the relationship among miR-210-3p, Wnt signaling pathway, and the differentiation of rBMSCs. The results indicated that ERα-deficient inhibited osteogenic differentiation, promoted adipogenic differentiation, and regulated the expression of some miRNAs. Meanwhile, overexpression of miR-210-3p promoted osteogenic differentiation and inhibited adipogenic differentiation of rBMSCs, processes likely to be related to the Wnt signaling pathway. In conclusion, we identified a group of upregulated and downregulated miRNAs in ERα-deficient rBMSCs that might play a vital role in regulating osteogenic or adipogenic differentiation. One of these, miR-210-3p, inhibited osteogenic differentiation and promoted adipogenic differentiation correlated with the Wnt signaling pathway in ERα-deficient rBMSCs, providing new insight into the regulation of bone metabolism.

MOLECULAR THERAPY-NUCLEIC ACIDS 2019; 17:223-234.

Abstract
Patients who sustain a traumatic brain injury (TBI) are known to have a significantly quicker fracture healing time than patients with isolated fractures, but the underlying mechanism has yet to be identified. In this study, we found that the upregulation of miRNA-26a-5p induced by TBI correlated with a decrease in phosphatase and tensin homolog (PTEN) in callus formation. In vitro, overexpressing miRNA-26a-5p inhibited PTEN expression and accelerated osteoblast differentiation, whereas silencing of miRNA-26a-5p inhibited osteoblast activity. Reduction of PTEN facilitated osteoblast differentiation via the PI3K/AKT signaling pathway. Through luciferase assays, we found evidence that PTEN is a miRNA-26a-5p target gene that negatively regulates the differentiation of osteoblasts. Moreover, the present study confirmed that preinjection of agomiR-26a-5p leads to increased bone formation. Collectively, these results indicate that miRNA-26a-5p overexpression may be a key factor governing the improved fracture healing observed in TBI patients after the downregulation of PTEN and PI3K/AKT signaling. Upregulation of miRNA-26a-5p may therefore be a promising therapeutic strategy for promoting fracture healing.

Ribes orientale: A novel therapeutic approach targeting rheumatoid arthritis with reference to pro-inflammatory cytokines, inflammatory enzymes and anti-inflammatory cytokines. JOURNAL OF ETHNOPHARMACOLOGY 2019; 237:92-107. [PMID: 30872172 DOI: 10.1016/j.jep.2019.03.019] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2018] [Revised: 01/22/2019] [Accepted: 03/06/2019] [Indexed: 05/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The roots of Ribes orientale (Family Grossulariaceae) have long been used as a folk remedy to treat rheumatism and joints pain in Northern Areas of Pakistan. AIM OF THE STUDY The purpose of study was to observe the preventive efficacy of roots of Ribes orientale (RO) aqueous ethanolic extract (30:70) and its aqueous and n-butanol fractions in treating rheumatoid arthritis and to determine its possible mechanism of action. MATERIAL AND METHODS Arthritis was evaluated in vitro using heat induced bovine serum albumin and egg albumin denaturation and membrane stabilizing assays at 50-6400 μg/ml concentration of extract/fractions whereas, in vivo arthritis was evaluated at 50, 100, 200 mg/kg doses of extract/fractions in formaldehyde model by measuring rat paw volume/diameter. Moreover, highest effective dose (200 mg/kg) of extract/fractions was evaluated in Freünd complete adjuvant (FCA) model. Arthritis was induced in Sprague Dawley rats by immunization with 0.1 ml FCA in left footpad. RO extract/fractions at 200 mg/kg were orally administered from day 0, 30 min prior to adjuvant injection and sustained for 28 days. Paw volume/diameter, arthritic score, body weight, and hematological (WBC, RBC, ESR, Hb and Platelet count) and biochemical (AST, ALT, ALP, urea, creatinine, CRP and RF) parameters were observed. The mRNA expression levels of COX-2, IL-1β, IL-6, NF-kB, TNF-α, IL-4 and IL-10 were measured by real time reverse transcription polymerase chain reaction (RT-PCR) whereas, PGE2 and TNF-α levels in serum samples were measured by Enzyme linked immunosorbent assay (ELISA). Furthermore, radiographs of hind paws and histological changes in ankle joint were analyzed in adjuvant injected rats. The anti-oxidant activity of plant extract and fractions was evaluated using DPPH and reducing power assays. In addition, phytochemistry, total phenolic and flavonoid contents, and HPLC analysis of most active fraction (aqueous fraction) were performed. RESULTS Results showed that RO extract and fractions (notably aqueous fraction) significantly reduced protein denaturation and protected erythrocyte membrane in concentration dependent manner. Similarly, extract/fractions induced dose-dependent decrease in paw volume/diameter in the formaldehyde model. Plant extract and fractions significantly suppressed paw swelling and arthritic score, prevented cachexia and remarkably ameliorated hematological and biochemical changes. Furthermore, RO extract/fractions downregulated gene expression levels of PGE2, COX-2, IL-1β, IL-6, NF-kB and TNF-α whereas, upregulated those of IL-4 and IL-10, compared with FCA control rats. The radiographic and histopathologic improvement in joint architecture was also observed in RO treated rats. Piroxicam, used as reference drug, also significantly suppressed arthritis. Additionally, plant exhibited notable anti-oxidant activity and phytochemical analysis revealed the presence of flavonoids and polyphenols. CONCLUSION Results indicated that suppression of pro-inflammatory enzymes/cytokines, inhibition of protein denaturation, lysosomal membrane stabilizing abilities, and redox/free radical scavenging properties of RO extract and fractions support anti-arthritic and immunomodulatory property of Ribes orientale that might be due to its polyphenolic and flavonoid constituents. This suggests that Ribes orientale roots may be used as a therapeutic agent for treating human arthritis.

[PMID: 31100273 DOI: 10.1016/j.cbi.2019.05.017] [Citation(s) in RCA: 49] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Revised: 04/19/2019] [Accepted: 05/13/2019] [Indexed: 12/26/2022]
Abstract
Although Doxorubicin (DOX) is a widespread drug used in the treatment of cancer, its clinical use is restricted due to its common side effects. In addition, administrating DOX with an antioxidant has recently become a new strategy in preventing the side effects of DOX. The protective effects of morin, a natural flavonoid, against DOX-induced liver and kidney damage in rats were investigated biochemically, immunohistochemically and histopathologically in this study. The experimental procedure was planned as 10 days, and 5 groups consisting of seven rats were formed. Morin was given orally to rats at a dose of 50 and 100 mg/kg for 10 days and DOX was given a single dose of 40 mg/kg intraperitoneally on day 8. In order to determine the protective effect of morin against oxidative stress caused by DOX, reduced glutathione (GSH) and malondialdehyde (MDA) levels and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) enzyme activities were measured in liver and kidney tissues. Liver and kidney tissue damage were determined both histopathologically and by serum alanine transaminase (ALT), aspartate transaminase (AST), urea and creatinine analysis. In order to determine the effect of DOX-induced inflammation and against the effect of morin, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and nuclear factor kappa B (NF-κB) levels were determined in both tissues. Liver and kidney B-cell lymphoma-2 (Bcl-2) levels were determined biochemically. In addition, Bax expression in liver tissue and aquaporin-2 (AQP-2) and nephrin expression in renal tissue were determined immunohistochemically. It was determined that oxidative damage caused by DOX decreased and improvement of liver and kidney function markers were observed in the groups that were treated with morin. In addition, pre-treatment of morin showed a regulatory effect on TNF-α, IL-1β and NF-κB levels. It prevented the increase in DOX-induced Bax expression and decrease in Bcl-2 level, AQP-2 and nephrin expression. Histopathological examination revealed that it prevented tissue damage in liver and kidney tissues.

Hassan UH, Shahzad M, Shabbir A, Jahan S, Saleem M, Bukhari IA, Assiri AM. Amelioration of adjuvant induced arthritis in Sprague Dawley rats through modulation of inflammatory mediators by Ribes alpestre Decne. JOURNAL OF ETHNOPHARMACOLOGY 2019; 235:460-471. [PMID: 30771518 DOI: 10.1016/j.jep.2019.02.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Revised: 01/31/2019] [Accepted: 02/12/2019] [Indexed: 05/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ribes alpestre Decne has been commonly used in the treatment of joint complaints. AIM OF STUDY The present study was undertaken to evaluate the antiarthritic potential of ethanolic extract and fractions of Ribes alpestre and to explore its probable mechanism of action. MATERIAL AND METHODS Complete Freunds adjuvant induced arthritis in Sprague Dawley rats was used to assess antiarthritic activity of aqueous ethanol extract, butanol and aqueous fractions at 200 mg/kg oral dose for 28 days. Paw volume and diameter, arthritic index, body weight, hematological and biochemical parameters, radiographic and histological analysis of ankle joints were carried out. An array of pro-inflammatory mediators (IL-1β, IL-6, NF-Kβ, TNF-α, COX-2, IL-4, IL-10 and PGE2) were estimated by RT-PCR and enzyme linked immunosorbent assay. Antioxidant capacity was assessed using DPPH and reducing power assays. Qualitative phytochemical screening, total phenolic and flavonoid content and HPLC analysis of aqueous fraction of Ribes alpestre were also carried out. RESULTS Significant (p < 0.001) reduction in paw volume and thickness and arthritic score by aqueous ethanolic extract and its fractions has been found. Aqueous ethanolic extract and fractions in particular aqueous fraction considerably prevented decrease in body weight, alterations in hematological parameters. Radiographic and histological examination revealed no significant architectural changes in joints of treated rats. Significant (p < 0.05-0.001) down regulation of pro-inflammatory genes IL-1β, TNF-α, IL-6, COX-2, PGE2 and NF-Kβ alongwith noteworthy increase in levels of IL-4 and IL-10 was recorded among treated animals. Aqueous ethanol extract and its fractions demonstrated notable and concentration dependent (50-6400 μg/ml) antioxidant potential. Qualitative phytochemical analysis of active fraction (aqueous) displayed presence of flavonoids, alkaloids, tannins and glycosides. Besides total phenolic and flavonoid contents has been found to be 179.3 mg GAE/ml and 389.40 μg QE/ml in aqueous fraction of Ribes alpestre respectively. HPLC profile demonstrated presence of quercitin, chlorogenic acid, vanillic acid and cinamic acid in aqueous fraction. CONCLUSION Present communication suggests Ribes alpestre a potent antiarthritic therapy by ameliorating adjuvant arthritis in rats by downregulating proinflammatory mediators with up regulation of anti-inflammatory cytokines.

Abstract
Oleanolic acid (OA) is a hydroxyl pentacyclic triterpene acid (HTAs) used in various ailments. Inflammatory diseases may be profoundly influenced by iron (Fe) and zinc (Zn) status. We studied the anti-asthmatic effects of two metal complexes (Fe and Zn) of OA in the ovalbumin (OVA)-induced rat model. Delayed type hypersensitivity (DTH) was measured. Total and differential leucocyte count was done in blood as well as bronchoalveolar lavage fluid (BALF). The mRNA expression levels of pro-inflammatory cytokines were measured in lung tissue by reverse transcription polymerase chain reaction. The levels of cyclooxygenase-2 (COX-2), immunoglobulin E (IgE) and 5-lipoxygenase (5-LOX) were estimated by enzyme linked immunosorbent assay. Splenocyte proliferation was performed through BrdU uptake method and nitric oxide levels were measured by colorimetric assay kit. The acute toxicity study was also done for the complexes. The asthmatic group developed allergic airway inflammation shown by increased DTH and inflammatory markers in blood and BALF. OA + Fe and OA + Zn displayed significant decrease in DTH, NO, expression of IL-4, 5, 13, 17, toll-like receptor-2, nuclear factor-kappa B and tumor necrosis factor-α; serum IgE, COX-2, and 5-LOX. The metal complexes also attenuated OVA-stimulated splenocyte proliferation. While no hepatotoxic or nephrotoxic potential was shown by OA + Fe and OA + Zn. Our findings indicate that both OA + Fe and OA + Zn possess significant anti-asthmatic effect which may be ascribed to its immunomodulatory and anti-inflammatory features.

Abstract
Recently, there is growing interest in the natural bioactive components having anticancer activity. Thymoquinone (TQ), the principle active constituent of black seed (Nigella sativa), has promising properties including anticancer and chemosensitizing peculiarities. The anticancer power of TQ is accomplished by several aspects; including promotion of apoptosis, arrest of cell cycle and ROS generation. In addition, it boosts the immune system and lessens the side effects associated with traditional anticancer therapy. TQ also controls angiogenesis and cancer metastasis. This review focuses on the potential aspects and mechanisms by which TQ acquires its actions.

Abstract
Moringa rivae is widely used as a traditional remedy against arthritis. The present research was designed to evaluate the anti-arthritic potential of Moringa rivae extracts. Treatment of rats with adjuvant-induced arthritis with methanolic and aqueous extracts of M. rivae (150, 300 or 600 mg/kg), and piroxicam (10 mg/kg) was started orally at day 8 post-administration of complete Freund's adjuvant and continued till 28th day. The therapeutic effect of the plant extracts was assessed in arthritic rats by arthritic index, body weight, and haematological and biochemical parameters. Furthermore, the modulatory effect on gene expression (I-κB, IL-4 and IL-10, COX-2, IL-1β and IL-6, NF-κB, and TNF-α) in the blood was determined using qRT-PCR, while ELISA assay was used to find PGE2 and TNF-α concentrations in the serum. Oxidative stress parameters in the liver and ankle joint histopathology were also evaluated. Moreover, the most effective methanolic extract was further characterized by GC-MS for the presence of phytochemicals. Treatment with the plant extracts significantly restored arthritic index, change in the body weight and immune organ weight, and the histopathological indices. Both extracts significantly (p < 0.05) reduced the serum concentration of rheumatoid factor, C-reactive protein, PGE2, and TNF-α in arthritic rats. The extracts persuasively down-regulated the COX-2, PGE2, IL-1β, IL-6, NF-κB, and TNF-α, and up-regulated the mRNA expression of I-κB, IL-4, and IL-10. Both extracts increased the activities of CAT and SOD while reducing the formation of MDA in a dose- dependent manner in the liver. Histopathological evaluation showed that treatment with the plant extracts significantly (p < 0.05) reduced joint inflammation, pannus formation, and bone erosion in treatment groups in comparison to arthritic control. Phytochemicals detected by GC-MS in the methanolic extract included esters, alcohols, ketones, fatty acids, and vitamin E. These findings provide evidence of the anti-arthritic potential of M. rivae extracts in chronic polyarthritis model.

Abstract
NEW FINDINGS What is the central question of this study? What is the mechanism of wheat-induced pulmonary inflammation and how does a hydrazide derivative modulate it? What is the main finding and its importance? A hydrazide derivative significantly reduced wheat-induced pulmonary inflammation in a rat model mainly by down-regulating inflammatory cell infiltration, pathological lesions in the lungs and the level of pro-inflammatory cytokines, COX-1, COX-2 and T-cell proliferation. ABSTRACT We investigated the ameliorative anti-inflammatory effect of a previously synthesized hydrazide derivative (N'-(4-methoxybenzylidene)-6-(4-chlorophenyl)-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carbohydrazide; MD) as an immunomodulator in a newly developed allergen-induced pulmonary inflammation (AIPI) rat model. Wheat and thresher dust were used as allergens to induce pulmonary inflammation while MD was used to reverse the inflammatory response. Blood and bronchoalveolar lavage fluid (BALF) were collected after killing the rats and inflammatory cells were counted. Histological analysis of lung airways was carried out by haematoxylin and eosin and periodic acid-Schiff staining while the level of total serum IgE, interleukin (IL)-4, IL-5 and cyclooxygenase (COX)-1 in BALF and in vitro T-cell proliferation in spleen were measured through enzyme-linked immunosorbent assay. mRNA expression level of IL-4, IL-5, IL-13, transforming growth factor β (TGF-β), interferon-γ, tumour necrosis factor α, COX-1 and COX-2 was evaluated by qRT-PCR. A liver and kidney function test was used to observe any toxic impact of MD. The results indicated that 2 mg of wheat and thresher dust led to higher levels of inflammatory cytokines in the blood, BALF and lung airways of rats. MD potentially down-regulated the inflammatory cell infiltration in BALF and pathological lesions in the lung airways of AIPI rats. MD significantly suppressed the elevated total serum IgE, along with IL-4, IL-5, IL-13, TGF-β, COX-1 and COX-2 mRNA expression and T-cell proliferation in spleen. In conclusion, MD at 10 mg kg-1 exhibited a significant reduction in all the markers in both wheat- and thresher dust-induced pulmonary inflammation mainly by inhibiting pro-inflammatory cytokine production and T-cell proliferation. The data suggest that inhibition of the T-cell response may be responsible for the modulative effect of MD in an AIPI rat model.

Abstract
Ziziphora clinopodioides has been frequently used as an anti asthmatic plant in traditional medication. Recent work explores the anti-asthmatic activity of Z. clinopodioides in allergen-induced asthmatic mice. Intraperitoneal sensitization followed by intranasal challenge were given with ovalbumin (allergen) to develop allergic asthma. Investigational groups of animals were administered with drug methylprednisolone (MP) (15 mg/kg body weight), n-hexane fraction, ethylacetate fraction, and methanolic extract of Z. clinopodioides extract (500 mg/kg b.w.) for successive 07 days. Hematoxyline and eosin (H&E) and periodic acid-Schiff (PAS) stains were used to evaluate histopathological parameters on lung tissues. As an index of lungs tissues edema, wet/dry weight ratio of lungs was determined. Evaluation of expression levels of AQP1, AQP5, IL4, and IL5 was conducted by using RT-PCR. The data exhibited that both Z. clinopodioides and MP attenuated differential and total leukocyte counts in hematological examination i.e. in BALF and blood. Treatment with Z. clinopodioides also caused suppression of inflammatory cell infiltration and expression levels of IL4 and IL5, the later could have caused attenuation of pulmonary inflammation. The study also found decline in lung wet/dry ratio and goblet cellh hyperplasia in treated groups which indicates amelioration of lung edema. Treatment with Z. clinopodioides significantly increased the expression levels of aquaporin-1 and -5, which could have led to reduction in lung edema. The treatment with MP showed comparable results to Z. clinopodioides. Current investigation revealed that Z. clinopodioides possessed anti-asthmatic property which might be accredited to upregulagted AQP1 and AQP5 levels and downregulated IL4 and IL5 levels.

Abstract
Dipsacus asperoides C. Y. Cheng et T. M. Ai (DA) has been used in China as a traditional medicine to treat lumbar and knee pain, liver dysfunction, and fractures. We explored the suppressive effect of DA on allergic asthma using an ovalbumin (OVA)-induced asthma model. In the asthma model, female Balb/c mice were sensitized to OVA on day 0 and 14 to boost immune responses and then exposed to OVA solution by using an ultrasonic nebulizer on days 21 to 23. DA (20 and 40 mg/kg) was administered to mice by oral gavage on days 18 to 23. Methacholine responsiveness was determined on day 24 using a plethysmography. On day 25, we collected bronchoalveolar lavage fluid, serum, and lung tissue from animals under anesthesia. DA treatment effectively inhibited methacholine responsiveness, inflammatory cell infiltration, proinflammatory cytokines such as interleukin (IL)-5 and IL-13, and immunoglobulin (Ig) E in OVA-induced asthma model. Reductions in airway inflammation and mucus hypersecretion, accompanied by decreases in the expression of inducible nitric oxide synthase (iNOS) and the phosphorylation of nuclear factor kappa B (NF-κB), were also observed. Our results indicated that DA attenuated the asthmatic response, and that this attenuation was closely linked to NF-κB suppression. Thus, this study suggests that DA is a potential therapeutic for allergic asthma.

Abstract
BACKGROUND Hyssopus cuspidatus Boriss has been used to treat bronchial asthma for many years in Uighur medicine. JAX2, an ethanol extract from this plant, has effectiveness against bronchial asthma. However, the molecular basis for the anti-inflammatory effects of JAX2 remains unclear. PURPOSE This study aimed to evaluate the mechanism of JAX2 against bronchial asthma. METHODS We established an asthma model in rats using ovalbumin (OVA), and an inflammatory model in RAW264.7 cells using lipopolysaccharide (LPS) stimulation. To evaluate the anti-inflammatory effects of JAX2, the concentrations of tumor necrosis factor (TNF)-α, interleukin (IL)-4, IL-6, IL-17, eotaxin and immunoglobulin (Ig)E were measured by enzyme-linked immunosorbent assay (ELISA). Cell viability was investigated by the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)2H-tetrazolium, inner salt (MTS) assay. Further, nitric oxide (NO) and reactive oxygen species (ROS) were determined using Griess reagent and 2,7-dichlorofluorescein diacetate. The phosphorylation of p-extracellular signal-regulated kinase (ERK), p-Jun-NH2-terminal kinase (JNK), p38 kinases (p38) and p-inhibitor of nuclear factor kappa-B kinase (IKK), and nuclear translocation of p-p65 kinases (p-p65) were determined by immunofluorescence to uncover the effects of JAX2 on the Mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways. RESULTS After JAX2 administration to rats, Interferon (IFN)-γ concentrations in BALF increased significantly. Further, the concentrations of TNF-α, IL-4, IL-6, IL-17 and eotaxin in BALF, and IgE in serum decreased. JAX2 decreased TNF-α, IL-6 and NO in cell supernatant, and reduced ROS intracellularly. Concurrently, IFN-γ concentrations increased in cell supernatant significantly. In LPS-induced RAW264.7 cells, JAX2 inhibited phosphorylation of p-ERK, p-JNK and p-38 MAPK. The subsequent phosphorylation of p-IKK and nuclear translocation of the p-p65 subunit of NF-κB were also suppressed. CONCLUSION Based on these findings, we believe that JAX2 has both preventive and treatment effects in bronchial asthma. Furthermore, in the RAW264.7 cell inflammatory model, JAX2 also inhibited NF-κB and MAPK signaling pathways.

Abstract
Pterocephalus hookeri was used as a traditional Chinese medicine for the treatment of rheumatoid arthritis. Sweroside was a main iridoid isolated from P. hookeri. The present study aimed to investigate the anti-inflammatory effect mechanism of sweroside. In RAW264.7 cells induced by lipopolysaccharide (LPS), the abnormal proliferation, the NO content increase, and the downregulated Sirtuin1 (SIRT1) expression were observed. Sweroside could alleviate the inflammation by inhibiting cell proliferation through arresting the cell cycle at the G0/G1 phase, by suppressing pro-inflammatory cytokines and by promoting anti-inflammatory cytokines in LPS-induced RAW264.7 cells. Further mechanism research indicated that sweroside could activate the SIRT1, then suppress the nuclear factor-kappa B (NF-κB) and promote the Forkhead transcription factor O1 (FOXO1) signaling pathways. The present study indicated that sweroside may be the main anti-inflammatory constituent of P. hookeri and a promising candidate for anti-inflammation therapy.

Abstract
Objective To examine the feasibility of fractional exhaled nitrous oxide (FeNO) guided stepped care in patients with chronic persistent asthma. Methods 160 patients with asthma were enrolled and randomly divided into study and control groups, and were given standardized treatment according to GINA 2014. All patients were evaluated every 3 months and their medication was adjusted according to the results of evaluation. The control group was adjusted according to the recommended protocol from GINA, while the study group was adjusted on the basis of the control group and combined with the results of FeNO. The complete control rate, failure rate of stepwise treatment, ACQ score, lung function, and peripheral blood eosinophil count were compared between the two groups. Results In both study and control groups, the patient condition was effectively controlled. Strikingly, the failure rate of step therapy in study group was lower than that of control group (P<0.05), although there were no significant differences between the two groups on total control rate, ACQ score, lung function, and peripheral blood eosinophil count (P>0.05). Furthermore, the levels of FeNO positively correlated with ACQ scores and eosinophil counts or negatively with lung function. Conclusions The dynamic monitoring of FeNO could effectively guide the medication and reduce the rate of treatment failure, which could be used to inform standardized management of asthma.

Abstract
Phenotypic variation in skeletal traits and diseases is the product of genetic and environmental factors. Epigenetic mechanisms include information-containing factors, other than DNA sequence, that cause stable changes in gene expression and are maintained during cell divisions. They represent a link between environmental influences, genome features, and the resulting phenotype. The main epigenetic factors are DNA methylation, posttranslational changes of histones, and higher-order chromatin structure. Sometimes non-coding RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are also included in the broad term of epigenetic factors. There is rapidly expanding experimental evidence for a role of epigenetic factors in the differentiation of bone cells and the pathogenesis of skeletal disorders, such as osteoporosis and osteoarthritis. However, different from genetic factors, epigenetic signatures are cell- and tissue-specific and can change with time. Thus, elucidating their role has particular difficulties, especially in human studies. Nevertheless, epigenomewide association studies are beginning to disclose some disease-specific patterns that help to understand skeletal cell biology and may lead to development of new epigenetic-based biomarkers, as well as new drug targets useful for treating diffuse and localized disorders. Here we provide an overview and update of recent advances on the role of epigenomics in bone and cartilage diseases. © 2019 American Society for Bone and Mineral Research.

Abstract
S-Allyl cysteine (SAC) is an active component in garlic and has various pharmacological effects, such as anti-inflammatory, anti-oxidant, and anti-cancer activities. In this study, we explored the suppressive effects of SAC on allergic airway inflammation induced in an ovalbumin (OVA)-induced asthma mouse model. To induce asthma, BALB/c mice were sensitized to OVA on days 0 and 14 by intraperitoneal injection and exposed to OVA from days 21 to 23 using a nebulizer. SAC was administered to mice by oral gavage at a dose of 10 or 20 mg/kg from days 18 to 23. SAC significantly reduced airway hyperresponsiveness, inflammatory cell counts, and Th2 type cytokines in bronchoalveolar lavage fluid induced by OVA exposure, which was accompanied by reduced serum OVA-specific immunoglobulin E. In histological analysis of the lung tissue, administration of SAC reduced inflammatory cell accumulation into lung tissue and mucus production in airway goblet cells induced by OVA exposure. Additionally, SAC significantly decreased MUC5AC expression and nuclear factor-κB phosphorylation induced by OVA exposure. In summary, SAC effectively suppressed allergic airway inflammation and mucus production in OVA-challenged asthmatic mice. Therefore, SAC shows potential for use in treating allergic asthma.

Abstract
Oxyresveratrol, an active ingredient of Artocarpus lakoocha, is known to possess anti-inflammatory and immunomodulatory properties. Current study investigates the immunomodulatory effect of oxyresveratrol in mouse model of ethanol-induced ulcer. Anti-ulcer effect was determined using histopathological evaluation (H&E staining) and different tests like, gastric ulcer scoring, ulcer index, total acid secretion, and gastric pH. The mRNA expression levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), nuclear factor-kappaB (NF-ĸB), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and trefoil factor 2 (TFF-2) were evaluated using reverse transcription polymerase chain reaction (RT-PCR). The data showed marked percentage inhibition of erosion, hemorrhage, fibrinoid necrosis, inflammatory infiltrate, and ulcer in low (30 mg/kg b.w.) and high dose (50 mg/kg b.w.) groups of oxyresveratrol. Treatment with oxyresveratrol inhibited ulcer score and ulcer index as compared with disease control group. Oxyresveratrol significantly increased gastric pH (P < 0.001) and attenuated total acid (P < 0.001) secretion. RT-PCR analysis showed significant suppression in the mRNA expression levels of IL-6 (P < 0.001), TNF-α (P < 0.01), NF-ĸB (P < 0.001), and COX-2 (P < 0.05) in oxyresveratrol treated groups, while COX-1 expression levels were found unaltered. Treatment with oxyresveratrol significantly elevated (P < 0.01) the expression levels of cytoprotective TFF-2 levels. Similar Immunomodulatory and anti-ulcer effects were found with ranitidine treatment, which was used as a reference drug. In conclusion, oxyresveratrol possess significant anti-ulcer property which might be attributed to attenuated expression levels of IL-6, TNF-α, NF-ĸB, and COX-2 and elevated expression levels of TFF-2.

Abstract
Asthma is characterized by airway inflammatory infiltration, which leads to airway remodeling and airway hyperreactivity. Coleus forskohlii (CFK) has been used to treat asthma, however, the mechanism involved is not clear. To explore the antiasthma mechanism of extracts of Coleus forskohlii (ECFK), guinea pigs were administered with a spray of phosphoric acid histamine, and rats were sensitized with ovalbumin (OVA). Hematoxylin and eosin staining (H&E) were used to evaluate pathological changes in lung tissue. Enzyme-linked immunosorbent assay (ELISA) was used to determine cytokine levels in serum and bronchoalveolar lavage fluid (BALF). Immunohistochemistry and Western blot analysis were used to assess the expression of intercellular cell adhesion molecule-1 (ICAM-1), phosphorylation of p65 (p-p65), matrix metallopeptidase 9 (MMP-9), and tissue inhibitor of metalloproteinase 1 (TIMP-1). After ECFK treatment, the asthma incubation period of guinea pigs was significantly prolonged. The H&E results showed that the number of eosinophils in the 12.8 g/kg ECFK group was significantly lower when compared with the control group. Moreover, ELISA results demonstrated that interleukin (IL)-4, IL-5, and IL-17 in serum and BALF were significantly decreased, and interferon-γ (IFN-γ) and IL-10 were increased after ECFK treatment. In addition, ECFK treatment resulted in downregulation of ICAM-1, p-p65, MMP-9, and TIMP-1 in lung tissue after being sensitized by OVA. In conclusion, our findings indicated that ECFK significantly alleviated OVA-induced inflammatory infiltration and airway remodeling in asthma. This study laid a theoretical foundation for the clinical use of ECFK.

Effect of a Toothpaste/Mouthwash Containing Carica papaya Leaf Extract on Interdental Gingival Bleeding: A Randomized Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15122660. [PMID: 30486374 PMCID: PMC6313435 DOI: 10.3390/ijerph15122660] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Revised: 11/13/2018] [Accepted: 11/23/2018] [Indexed: 12/31/2022]
Abstract
Clinical research on herbal-based dentifrice +/− mouth rinse products is very limited compared with the plethora of research on conventional oral care products under normal oral hygiene conditions. The aim of this study was to determine the anti-inflammatory effects of a novel plant Carica papaya leaf extract (CPLE) on interdental bleeding in healthy subjects. In this randomized, single-blind parallel-design study, the eligible subjects were generally healthy non-smokers, aged 18–26, who exhibited healthy periodontal conditions upon study entry. The participants were equally randomized into the following four groups: CPLE dentifrice, CPLE dentifrice and mouthwash, sodium lauryl sulfate (SLS)-free enzyme-containing dentifrice and SLS-free enzyme-containing dentifrice with essential oil (EO) mouthwash. Subjects were instructed to brush their teeth twice a day without changing their other brushing habits. Interdental bleeding (BOIP) was measured from inclusion (T0) until the fourth week (T4) of the study. Clinical efficacy was assessed after one, two, three and four weeks of home use. The analyses compared BOIP between groups and were then restricted to participants with ≥70% and then ≥80% bleeding sites at T0. Pairwise comparisons between groups were performed at T0 and T4, and a logistic regression identified correlates of gingival bleeding (T4). Among 100 subjects (2273 interdental sites), the median percentage of bleeding sites per participant at T0 was 65%. The bleeding sites dramatically decreased in all groups between T0 and T4 (relative variations from −54% to −75%, p < 0.01 for all). Gingival bleeding did not significantly differ between the CPLE dentifrice and the SLS-free dentifrice +/− EO mouthwash groups (from p = 0.05 to p = 0.86), regardless of the baseline risk level. Among the CPLE dentifrice users, fewer bleeding sites were observed when toothpaste and mouthwash were combined compared to bleeding sites in those who used toothpaste alone (21% vs. 32%, p = 0.04). CPLE dentifrice/mouthwash provides an efficacious and natural alternative to SLS-free dentifrice +/−EO-containing mouthwash when used as an adjunct to mechanical oral care to reduce interdental gingival inflammation.

Abstract
The lung is the interface between air and blood where the exchange of oxygen and carbon dioxide occurs. The surface liquid that is directly exposed to the gaseous compartment covers both conducting airways and respiratory zone and forms the air-liquid interface. The barrier that separates this lining fluid of the airways and alveoli from the extracellular compartment is the pulmonary epithelium. The volume of the lining fluid must be kept in a range that guarantees an appropriate gas exchange and other functions, such as mucociliary clearance. It is generally accepted that this is maintained by balancing resorptive and secretory fluid transport across the pulmonary epithelium. Whereas osmosis is considered as the exclusive principle of fluid transport in the airways, filtration may contribute to alveolar fluid accumulation under pathologic conditions. Aquaporins (AQP) facilitate water flux across cell membranes, and as such, they provide a transcellular route for water transport across epithelia. However, their contribution to near-isosmolar fluid conditions in the lung still remains elusive. Herein, we discuss the role of AQPs in the lung with regard to fluid homeostasis across the respiratory epithelium.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Annona species (Annonaceae) have long been used as traditional herbal medicines by native peoples in tropical areas. In different countries they are used against a large variety of illnesses, such as parasitic and infectious diseases, cancer, diabetes, peptic ulcers, and mental disorders. AIM OF THE STUDY This review aims to achieve a comprehensive understanding of the research conducted so far on the local and traditional uses, pharmacological activities, mechanism of actions of active compounds, toxicity, and possible interactions with other drugs of the Annona species. Through analysis of these findings, evidences supporting their applications in ethno-medicines are described. We discuss the possible research opportunities and stand out the weak points in our knowledge that deserves further investigation. MATERIAL AND METHODS Information on ethno-medicinal uses and pharmacological activities of the Annona genus was collected. The main scientific biomedical literature databases (Cochrane, PubMed, Scopus, Lilacs, SeCiMed, Elsevier, SpringerLink, Google Scholar, SciFinder) were consulted. The search covered all the literature available until September 2017. National and regional databases of Herbal Medicine and Complementary and Alternative Medicine were also revised in order to explore further data. For a better understanding of the therapeutic importance of these species, we have classified the pharmacological activities within each group of disorders. The International Classification of Diseases (ICD), used from WHO Member States, was chosen as the reference classification. RESULTS From among the 27 species revised, four species are highlighted for their important pharmacological activities in most of the groups of illnesses: A. muricata, A. squamosa, A. senegalensis, and A. cherimola. Many investigations have been performed with extracts from the leaves, bark, fruit and seeds and have shown a wide range of pharmacological activities, such as antiprotozoal, antitumoural, antidiabetic, hepato-protective, anti-inflammatory and anxiolytic activities. The chemistry on the annonaceous acetogenins (ACGs) has been extensively investigated due to their potent antitumoural activity. Many of the assays were carried out with the isolated acetogenins in different lines of tumour culture cells and were found effective at very low doses even in multidrug-resistant tumours, and hence constitute promising compounds in the treatment of different types of cancers. No studies were found with extracts rich in acetogenins in the clinical field. CONCLUSIONS The experimental results from the pharmacological research enable the validation of their traditional uses in several of the groups of diseases in the countries of origin and reveal these plants to be a valuable source for therapeutic molecules. However, more toxicity assays and clinical trials would be necessary to establish optimal and safe doses of consumption on the application of these medicinal plants.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The whole plant, roots and stems of Ephedra gerardiana (Family Ephedraceae) have long been used as a folk remedy to treat rheumatism and painful joints in Northern Areas of Pakistan. AIM OF THE STUDY The purpose of study was to observe the preventive efficacy of Ephedra gerardiana (EG) aerial parts in treating rheumatoid arthritis using Freund's complete adjuvant (FCA) induced arthritis in rat model and to determine its possible mechanism of action. MATERIAL AND METHODS Arthritis was induced in Sprague Dawley rats by immunization with 0.1 ml FCA in left footpad. EG aqueous ethanolic extract (30:70) and its aqueous, n-butanol and ethyl acetate fractions at 200 mg/kg were orally administered from day 0, 30 min prior to adjuvant injection and sustained for 28 days. Paw volume/diameter, arthritic score, body weight, and hematological (WBC, RBC, ESR, Hb and Platelet count) and biochemical (AST, ALT, ALP, urea, creatinine, CRP and RF) parameters were observed. The mRNA expression levels of COX-2, IL-1β, IL-6, NF-kB, TNF-α, IL-4 and IL-10 were measured by real time reverse transcription polymerase chain reaction (RT-PCR) while, PGE2 and TNF-α levels in serum samples were measured by Enzyme linked immunosorbent assay (ELISA). Moreover, radiographs of hind paws and histological changes in ankle joint were analyzed in adjuvant injected rats. In addition, anti-oxidant activity of plant extract and fractions was also evaluated using DPPH and reducing power assays. Also, preliminary phytochemistry and total phenolic and flavonoid contents were investigated in most active fraction (aqueous fraction). RESULTS EG extract and fractions (notably aqueous fraction) significantly suppressed paw swelling and arthritic score, prevented cachexia and remarkably ameliorated hematological and biochemical changes. Furthermore, the overproduction of PGE2, COX-2, IL-1β, IL-6, NF-kB and TNF-α were remarkably attenuated in all EG treated rats, however, IL-4 and 10 were markedly increased. The radiographic and histopathologic improvement in joint architecture was also observed in EG treated rats. Piroxicam, used as reference drug, also significantly suppressed arthritis. Additionally, plant exhibited notable anti-oxidant activity and phytochemical analysis revealed the presence of alkaloids, flavonoids, phenols, tannins, saponins and glycosides. CONCLUSION These results indicate that EG extract and fractions significantly attenuated adjuvant arthritis in rats by decreasing the levels of aforementioned pro-inflammatory and increasing the levels of anti-inflammatory mediators. This suggests that Ephedra gerardiana aerial parts might be used as a therapeutic agent for treating human arthritis.

TNF-α increases the expression of inflammatory factors in synovial fibroblasts by inhibiting the PI3K/AKT pathway in a rat model of monosodium iodoacetate-induced osteoarthritis. Exp Ther Med 2018; 16:4737-4744. [PMID: 30542428 DOI: 10.3892/etm.2018.6770] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2017] [Accepted: 07/13/2018] [Indexed: 12/15/2022] Open
Abstract
Osteoarthritis is a degenerative disease that often causes patients to experience joint pain and deformity. It has been demonstrated that tumor necrosis factor (TNF)-α is associated with the progression of osteoarthritis; however, to the best of our knowledge, the mechanisms by which TNF-α simulates the progression of osteoarthritis and the signaling pathway(s) it influences remain unknown. Therefore, the aim of the present study was to investigate the therapeutic effects of TNF-α inhibitor in an iodoacetate-induced rat model of osteoarthritis and identify its potential mechanisms of action. Western blotting, ELISA and histological analyses were performed to assess the effects of the TNF-α inhibitor on osteoarthritis. The effects of TNF-α and phosphoinositide 3-kinase (PI3K) inhibition on synovial fibroblasts isolated from rats with osteoarthritis were tested in vitro. Furthermore, the expression of various inflammatory cytokines and the PI3K/protein kinase B (AKT) signaling pathway were assessed in vitro. The results indicated that the inflammatory factors TNF-α, interleukin (IL)-1β, IL-17a and IL-8 were upregulated in synovial fibroblasts taken from rats with osteoarthritis compared with normal rats. By contrast, TNF-α inhibition downregulated IL-1β, IL-17a and IL-8 expression in synovial fibroblasts in vitro. The PI3K/AKT pathway was also upregulated in synovial fibroblasts harvested from rats with osteoarthritis compared with that in normal rats. It was demonstrated that treatment with the TNF-α inhibitor downregulated the serum and protein levels of IL-1β, IL-17a and IL-8 in rats with osteoarthritis. Furthermore, treatment with the TNF-α inhibitor also decreased matrix metalloproteinase (MMP)-3, MMP-9, vascular endothelial growth factor and ADAMTS4 expression in synovial fibroblasts isolated from rats with osteoarthritis. Treatment with the TNF-α inhibitor also inhibited the PI3K/AKT pathway in synovial fibroblasts isolated from rats with osteoarthritis. Treatment with the PI3K inhibitor ameliorated TNF-α-induced increases in IL-1β, IL-17a and IL-8 expression in synovial fibroblasts isolated from rats with osteoarthritis. Furthermore, treatment with the TNF-α inhibitor decreased inflammation, as well as joint and cartilage destruction in vivo. Taken together, the results of the present study indicate that TNF-α inhibition may downregulate the expression of inflammatory factors in synovial fibroblasts, suggesting that TNF-α inhibition may be a novel method for treating osteoarthritis by downregulating the PI3K/AKT signaling pathway.

Abstract
Puerarin has long been used as a traditional Chinese medicine, which possesses various physiological properties, including anti-inflammation, anti-oxidative, anti-diabetic and anti-cancer activities. The aim of the current study was to investigate the effect of puerarin on delayed-type hypersensitivity (DTH) induced by ovalbumin (OVA) in mice and explore its underlying mechanisms. The results showed that puerarin significantly attenuated DTH, resulting from a decrement in footpad swelling, reduction in inflammatory cell as well as a decline in anti-OVA IgG in serum. In the homogenized supernatant of footpad tissues, the classic Th1-cytokines, including interferon (IFN)-γ was suppressed following puerarin treatment. Furthermore, a high dose of puerarin inhibited interleukin (IL)-4 production, the classic Th2-cytokine. The concanavalin A stimulation and MTT assays indicated a suppressive effect of puerarin on Th1 response via decreasing IFN-γ production in OVA-primed lymphocytes. Detailed studies revealed that puerarin modulated the Th1/Th2 balance in DTH responses, attributing to lower T-bet/GATA binding protein-3 mRNA and protein level ratios, which led to the shift change of IFN-γ/IL-4 with puerarin treatment. These findings demonstrate that puerarin alleviated inflammation in DTH triggered by OVA application via curbing inflammatory cytokines by modulating the Th1/Th2 balance. These results suggest that puerarin may be an alternative therapeutic option for the treatment of DTH.

Abstract
In this research work, we report the synthesis and biological evaluation of two new series of 1-benzyl-4-(benzylidenehydrazono)-3,4-dihydro-1H-benzo[c] [1,2]thiazine 2,2-dioxides and 1-benzyl-4-((1-phenylethylidene)hydrazono)-3,4-dihydro-1H-benzo[c][1,2]thiazine 2,2-dioxides. The synthetic plan involves the mesylation of methyl anthranilate with subsequent N-benzylation of the product. The methyl 2-(N-benzylmethylsulfonamido)benzoate was subjected to cyclization reaction in the presence of sodium hydride to obtain 1-benzyl-1H-benzo[c][1,2]thiazin-4(3H)-one 2,2-dioxide which was treated with hydrazine hydrate to get corresponding hydrazone precursor. Finally, the titled compounds were obtained by reaction of hydrazone with various substituted aldehydes and ketones. The synthesized derivatives were subjected to carry out their inhibition activities against monoamine oxidases along with modelling investigations to evaluate their binding interactions and dynamic stability during the docking studies. The inhibition profile of potent compounds was found as competitive for both the isozymes. The compounds were more selective inhibitors of MAO-A as compared to MAO-B. Moreover, drug likeness profile of the derivatives was evaluated to have an additional insight into the physicochemical properties. The molecular dynamic simulations predicted the behaviour of amino acids with the active site residues.

Abstract
Previous studies have indicated that smooth muscle myosin light chain kinase (MLCK) has a prominent role in the regulation of smooth muscle contraction, which tends to be upregulated in asthma. In recent years, numerous studies have reported that MLCK is intimately connected with the immunoregulatory mechanism of T cells. The imbalance of T helper type 1 cells (Th1)/Th2 constitutes the immune-associated pathological basis of chronic asthma. Th2-associated cytokines, including interleukin-4, −5, −13, −25 and −33, are involved in airway inflammation, hyperresponsiveness and remodeling, which leads to a progressive decline in lung function. The purpose of the present study was to verify whether inhibition of bronchial MLCK attenuated the expression Th2-associated cytokines in asthmatic mice, including the above-mentioned ones. Female BALB/c mice were used to establish an ovalbumin (OVA)-induced model of asthma, of which one group was treated with the MLCK inhibitor (5-iodonaphthalene-1-sulfonyl) homopiperazine (ML-7). The inhibitor of MLCK, ML-7 attenuated airway inflammation and remodeling by reducing inflammatory cell infiltration and the secretion of Th2 cytokines in mice model of asthma, which may represent a promising therapeutic strategy for asthma.

Abstract
Background Tulobuterol patch, one of strongest bronchodilators, was recently shown to improve bronchial hyperresponsiveness and significantly decrease the sputum eosinophil counts by combining with nonspecific anti-inflammatory drugs on patients with asthma. However, there is limited study on the anti-inflammatory activities of tulobuterol patch and its potential machenism. Results The tulobuterol patch significantly ameliorated inflammatory cell infiltration in the lung tissue, reduced the number of total leukocytes and its differential count, markedly reduced the production of IL-1β, TNF-α, IL-6, CCL-11 and IL-4 in bronchial alveolar lavage fluid, as well as a reduction in IL-4/IFN-γ ratio. Tulobuterol patch exhibited the best effect on allergic inflammation compared with formoterol and salbutamol. Furthermore, tulobuterol patch treatment significantly suppressed the expression and activation of Syk and its downdream signaling NF-κB and p-NF-κB. Conclusions The present studies revealed that tulobuterol patch effectively ameliorated airway inflammatory responses in allergic asthma, and its mechanisms, at least partially, via down-regulating Syk/NF-κB pathway. Methods An ovalbumin induced allergic asthma mouse model were used, and the effects of tulobuterol patch on allergic airway inflammation were evaluated. Also, its anti-airway inflammatory potential was compared with two other β2-agonists, salbutamol and formoterol. Its possible anti-inflammatory mechanisms were identified by using western blotting and immunohistochemistry.

Abstract
OBJECTIVE To study the influence of glycyrrhetinic acid (GA) on bronchial asthma (BA) smooth muscle proliferation and apoptosis as well as inflammatory factor expression and its molecular mechanism. METHODS Male SD guinea pigs were selected and made into asthma models, bronchial asthma smooth muscle cells were cultured and divided into BA group, GA group and GA + LM group that were treated with serum-free RPMI1640 culture medium, serum-free RPMI1640 culture medium containing 50 ng/mL glycyrrhetinic acid, serum-free RPMI1640 culture medium containing 50 ng/mL glycyrrhetinic acid and 100 ng/mL LM22B-10 respectively; normal guinea pigs were collected and bronchial smooth muscle cells were cultured as control group. The cell proliferation activity as well as the expression of proliferation and apoptosis genes, inflammatory factors and p-ERK1/2 was determined. RESULTS Proliferation activity value and mRNA expression of Bcl-2, TNF-α, IL-4, IL-6, YKL-40, protein expression of p-ERK1/2 of airway smooth muscle cell in BA group were significantly higher than those of control group while mRNA expression levels of Bax, caspase-9 as well as caspase-3 were significantly lower than that of control group (P < 0.05); proliferation activity value and mRNA expression of Bcl-2, TNF-α, IL-4, IL-6, YKL-40, protein expression of p-ERK1/2 of airway smooth muscle cell in GA group were significantly lower than those of BA group (P < 0.05) while the mRNA expression levels of Bax, caspase-9 as well as caspase-3 were significantly higher than those of BA group (P < 0.05); proliferation activity value and mRNA expression of Bcl-2, TNF-α, IL-4, IL-6, YKL-40 of airway smooth muscle cell in GA + LM group were significantly higher than those of GA group (P < 0.05) while mRNA expression levels of Bax, caspase-9 as well as caspase-3 were significantly lower that of GA group (P < 0.05). CONCLUSION GA can inhibit the proliferation of bronchial smooth muscle cells and reduce the expression of inflammatory factors by inhibiting the phosphorylation of ERK1/2.
