Abstract
BACKGROUND Phenylbutazone (PBZ) is the most commonly used drug to treat symptoms of lameness in horses; however, it is associated with adverse effects such as gastric ulcer syndrome (EGUS). Interestingly, many practitioners prescribe omeprazole (OME) concurrently with PBZ to prevent the development of EGUS. However, the efficacy and safety of this practice in Mongolian horses with chronic lameness remain unknown. OBJECTIVES To evaluate the clinical effects of a combination of PBZ and OME on chronic lameness in Mongolian horses. STUDY DESIGN Randomised block experimental design. METHODS Eighteen Mongolian horses with lameness score was ≥3 points, were divided into three treatment groups, with six horses in each group: placebo (CON), PBZ (4.4 mg/kg PO q. 24 h), or PBZ plus OME (4 mg/kg PO q. 24 h; PBZ + OME) in a randomised block design based on the initial lameness score. The horses were treated for 15 days. During this period, weekly gastroscopy, and physiological and biochemical tests were performed. RESULTS Both PBZ (median 1.0, interquartile range [IQR]: 0.8-1.3; p = 0.01) and PBZ + OME (median 1.0, IQR: 1.0-1.0; p = 0.01) significantly decreased the lameness score compared with before administration. In addition, PBZ significantly increased the equine glandular gastric disease (EGGD) score (3.0 ± 0.6, p < 0.001), GT-17 content (293.4 ± 21.8 pg/mL, p < 0.001), and pepsinogen-1 (PG1) content (295.3 ± 38.3 ng/mL, p < 0.001) compared with CON or PBZ + OME. However, it significantly reduced the total protein (53.6 ± 1.5 g/L, p < 0.05) and albumin (25.5 ± 1.8 g/L, p < 0.05) contents. Nevertheless, compared with PBZ, PBZ + OME significantly decreased the EGGD score (0.3 ± 0.5, p < 0.001) and significantly increased the gastric fluid pH (7.3 ± 0.5, p < 0.001), total protein content (62.5 ± 4.6 g/L, p = 0.009), and albumin content (29.4 ± 1.1 g/L, p = 0.004). Meanwhile, they significantly diminished the gastrin 17 (GT-17) (162.0 ± 21.0 pg/mL, p < 0.001) and PG1 (182.4 ± 22.5 ng/mL, p < 0.001) contents. MAIN LIMITATIONS Individual differences in horses were larger, but the sample size was small. There was larger interval between observations for each index. CONCLUSIONS Compared with PBZ alone, PBZ + OME had no therapeutic effect on chronic lameness; however, it reduced the occurrence of EGGD in Mongolian horses. Horses may be protected against chronic lameness and PBZ-induced EGGD by increasing the pH value, decreasing serum PG1 and GT-17 content, and preventing the reduction of myeloperoxidase content.

Investigating the prilling/vibration technique to produce gastric-directed drug delivery systems for misoprostol. Int J Pharm 2024; 651:123762.

Abstract
Prilling/vibration technique to produce oral microcapsules was explored to achieve local delivery of misoprostol (MIS), a prostaglandin E1 analogue indicated for the treatment of gastric-duodenal ulcers, at the gastric mucosa. To improve MIS chemical stability and reduce its associated systemic side effects, drug delivery systems were designed and developed as microcapsules consisting of a core of sunflower oil and MIS (Fs6 and Fs14) or a MIS complex with hydroxypropyl-beta-cyclodextrin (HP-β-CD) (Fs18), confirmed by specific studies, and a polymeric shell. The produced microcapsules showed high encapsulation efficiencies for those with MIS solubilized in sunflower oil (>59.86 %) and for the microcapsules with MIS/HP-β-CD (97.61 %). To demonstrate the ability of these systems to deliver MIS into the stomach, swelling and drug release experiments were also conducted in simulated gastric fluid. Among the three formulations, FS18 showed gastric release within 30 min and was the most advantageous formulation because the presence of the MIS/HP-β-CD inclusion complex ensured a greater ability to stabilise MIS in the simulated gastric environment. In addition, these new systems have a small size (<540 µm), and good flow properties and the dose of the drug could be easily adapted using different amounts of microcapsules (flexibility), making them a passepartout for different age population groups.

Front Nutr 2022; 9:857255. [PMID: 35464001 PMCID: PMC9026188 DOI: 10.3389/fnut.2022.857255] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 03/04/2022] [Indexed: 11/23/2022] Open
Abstract
Sepsis causes platelet activation, systemic inflammation, organ dysfunction, and mortality. Endotoxins play an important role in the manifestation of the symptoms of septic shock. As fish oil exert well known anti-inflammatory effects and sunflower seed oil exert less anti-inflammatory properties than fish oil, both oils are widely used. We aimed to test the hypothesis that dietary supplementation of these two oils before endotoxemia modulates the consequences of illness. Nine- to ten-week-old male Wistar rats (N = 55) were divided into four groups: group A (N = 6), control; group B (N = 17), saline + lipopolysaccharide (endotoxin); group C (N = 17), fish oil + lipopolysaccharide; and group D (N = 15), sunflower seed oil + lipopolysaccharide. After 28 days of feeding the designated diet, the rats in all groups were intraperitoneally injected with lipopolysaccharide. After 24 h, survival rate, endotoxemia severity, levels of platelet activation markers, organ function and biochemical variables were evaluated. Platelet-leukocyte aggregation was significantly high in group C (p = 0.005), and platelet-monocyte aggregation was significantly high in groups C (p = 0.003) and D (p = 0.016) than in group B. The survival rate, endotoxemia severity, expression of platelet P-selectin, CD40L, and TLR4, pulmonary function, renal function, liver function, or biochemical variables did not significantly differ among groups B, C, and D. Instead of an anti-inflammatory effect, the dietary supplementation of fish and sunflower seed oils exerted a pro-inflammatory effect, especially via platelet-monocyte aggregation, suggesting a rebound effect of the dietary supplementation of the oils. The oils did not affect other inflammatory platelet markers or improve the outcome of endotoxemic rats. However, further studies are required to understand the underlying mechanisms of such effects and to elaborate the clinical significance of these findings.

Abstract
This review summarizes the use of spectroscopic processes-based analytical tools coupled with chemometric techniques for the identification of adulterants in edible oil. Investigational approaches of process analytical tools such asspectroscopy techniques, nuclear magnetic resonance (NMR), hyperspectral imaging (HSI), e-tongue and e-nose combined with chemometrics were used to monitor quality of edible oils. Owing to the variety and intricacy of edible oil properties along with the alterations in attributes of the PAT tools, the reliability of the tool used and the operating factors are the crucial components which require attention to enhance the efficiency in identification of adulterants. The combination of process analytical tools with chemometrics offers a robust technique with immense chemotaxonomic potential. These involves identification of adulterants, quality control, geographical origin evaluation, process evaluation, and product categorization.

Abstract
A new triterpenoid named 3β,20α-dihydroxy-30-nor-olean-12-ene-23,28 dioic acid (4) along with 3β-hydroxy-23-aldehyde-lup-20(29)-ene-28-oic acid (1), 3β-hydroxy-23-aldehyde-30-nor-olean-12,20(29)-diene-28-oic acid (2), 3β-hydroxy-lup-20(29)-ene-23,28 dioic acid (3), 3β-hydroxy-lup-20(29)-ene-23,28 dioic acid-23-O-β-D-glucopyranosyl ester (5), 3-O-β-D-glucuronopyranosyl-lup-20(29)-ene-23,28 dioic acid-28-O-β-D-glucopyranosyl ester (6), 3-O-β-D-glucuronopyranosyl-lup-20(29)-ene-23-aldehyde-28-oic acid-28-O-β-D glucopyranosyl ester (7) were isolated for the first time from the aerial parts of Anabasis articulata (Forssk) Moq. Isolated pure compounds were structurally elucidated using spectral analysis. Cytotoxic, antimicrobial, antiulcer activities and antioxidant parameters were evaluated using the total methanol extract and its successive fractions. The methylene chloride fraction showed strong cytotoxic activity against HepG-2 (6.9 µg/ml) and HCT-116 (5.5 µg/ml) tumour cell lines in comparative with 5-fluorouracil (7.9 µg/ml). Treatment of indomethacin induced ulcerated rats with ethyl acetate fraction (400 mg/kg, p.o./day) achieved reduced Ulcer index (0.18), potent inhibition percentage of ulceration (84.86%) in comparison to ranitidine and high antioxidant effect. Compound(6) exhibited high docking score against gastric H+/K+ ATPase.

Abstract
Aims: Delphinidin (DEL) is a plant-derived antioxidant with clinical potential to treat inflammatory pain but suffers from poor solubility and low bioavailability. The aim of the study was to develop a well-tolerated cyclodextrin (CD)-DEL complex with enhanced bioavailability and to investigate the mechanisms behind its antinociceptive effects in a preclinical model of inflammatory pain. Results: CD-DEL was highly soluble and stable in aqueous solution, and was nontoxic. Systemic administration of CD-DEL reversed mechanical and heat hyperalgesia, while its local application into the complete Freund's adjuvant (CFA)-induced inflamed paw dose-dependently reduced mechanical hyperalgesia, paw volume, formation of the lipid peroxidation product 4-hydroxy-2-nonenal (4-HNE), and tissue migration of CD68+ macrophages. CD-DEL also directly prevented 4-HNE-induced mechanical hyperalgesia, cold allodynia, and an increase in the intracellular calcium concentration into transient receptor potential ankyrin 1 expressing cells. Both 4-HNE- and CFA-induced reactive oxygen species (ROS) levels were sensitive to CD-DEL, while its capacity to scavenge superoxide anion radicals (inhibitory concentration 50 [IC50]: 70 ± 5 μM) was higher than that observed for hydroxyl radicals (IC50: 600 ± 50 μM). Finally, CD-DEL upregulated heme oxygenase 1 that was prevented by HMOX-1 siRNA in vitro. Innovation:In vivo application of DEL to treat inflammatory pain is facilitated by complexation with CD. Apart from its antioxidant effects, the CD-DEL has a unique second antioxidative mechanism involving capturing of 4-HNE into the CD cavity followed by displacement and release of the ROS scavenger DEL. Conclusion: CD-DEL has antinociceptive, antioxidative, and anti-inflammatory effects making it a promising formulation for the local treatment of inflammatory pain.

Abstract
Ulcer is the most common undesirable result of using non-steroid anti-inflammatory drugs such as indomethacin. In the present study, osajin was experimentally used on indomethacin-induced gastric ulcer in rats. Osajin was purified from Maclura pomifera (Raf.) C. K. Schneid fruits by using the chromatographic methods. Thirty six rats were divided into six groups as follows: healthy (control), IND (indomethacin), RAN (ranitidine, 25 mg/kg), OSJ 100 (osajin, 100 mg/kg), OSJ 200 (200 mg/kg) and OSJ 400 (osajin, 400 mg/kg). Following a 24-h fasting, IND was administered to the treatment groups at a dose of 25 mg/kg. RAN and OSJ were given orally to rats following 5 min of IND administration. Then, gastric tissues were taken 6 h after the IND administration. Determination of the ulcer area, pathological evidence, and biochemical indices such as lipid peroxidation, superoxide dismutase, glutathione, and catalase were performed. IND generated diffuse ulcer areas, severe hyperaemia, oedema, necrotic epithelium, and mononuclear cell infiltration in the mucosa, and significantly increased lipid peroxidation while also decreasing the glutathione concentration, superoxide dismutase and catalase activities of the tissue. OSJ and RAN showed significant amelioration on ulcer area and biochemical indices. Therefore, OSJ may be potentially therapeutic for gastric ulcers.

Abstract
This study was aimed to investigate the antihemorrhoidal effects of ethanol (CBE) and water extracts (CBW) of Capsella bursa-pastoris, an edible plant and a precipitant (CBW-1) obtained from the CBW in croton oil (CO)-induced hemorrhoid model in rats. CBW-1 was contain three organic acids, citric acid (36.09%), malic acid (35.56%), and quinic acid (17.73%). Hemorrhoids were evaluated by histopathology of recto-anal tissues and biochemical parameters in plasma and recto-anal tissues of rats. CBW, CBE, and CBW-1 significantly reduced hemorrhagic necrotic enteritis induced by CO. CO also increased the cytokines and lipid peroxidation (LPO) in serum, and myeloperoxidase (MPO) activity and LPO in recto-anal tissues, and reduced the GSH, CAT, GPx, and SOD levels in serum and recto-anal tissues. However, CBE, CBW, and CBW-1 ameliorated the levels of the cytokines, LPO, MPO, and the antioxidants. Our results conclude that the curative effect of Capsella bursa-pastoris is closely related with its organic acids constituents, citric, malic, and quinic acids. PRACTICAL APPLICATIONS: The fresh leaves of Capsella bursa-pastoris are edible, eaten raw or cooked, and also used in salad. It has a widespread traditional usage in the treatment of the hemorrhoids in the Anatolia and in the Middle East Countries. According to our literature survey, any scientific evidence has not been found in the literature that C. bursa-pastoris could be used in the treatment of hemorrhoids. Therefore, in the current study, we aimed to investigate the antihemorrhoidal and antioxidant effects of ethanol and water extracts, and a precipitant (CBW-1) obtained from the CBW of C. bursa-pastoris in croton oil (CO)-induced hemorrhoid model in rats. The current results showed that its water extract and CBW-1 containing three organic acids, citric acid (36.09%), malic acid (35.56%), and quinic acid (17.73%) significantly reduced the hemorrhagic necrotic enteritis induced by CO ameliorating the levels of the cytokines, LPO, MPO, and the antioxidants. Our results conclude that the curative effect of C. bursa-pastoris is closely related with its organic acids constituents, citric, malic, and quinic acids.

Abstract
Tocotrienol (T3) is a subfamily of vitamin E known for its wide array of medicinal properties. This review aimed to summarize the health benefits of T3, particularly in prevention or treatment of non-communicable diseases (NCDs), including cardiovascular, musculoskeletal, metabolic, gastric, and skin disorders, as well as cancers. Studies showed that T3 could prevent various NCDs, by suppressing 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) in the mevalonate pathway, inflammatory response, oxidative stress, and alternating hormones. The efficacy of T3 in preventing/treating these NCDs is similar or greater compared to tocopherol (TF). TF may lower the efficacy of T3 because the efficacy of the combination of TF and T3 was lower than T3 alone in some studies. Data investigating the effects of T3 on osteoporosis, arthritis, and peptic ulcers in human are limited. The positive outcomes of T3 treatment obtained from the preclinical studies warrant further validation from clinical trials.

Abstract
BACKGROUND Gastric ulcer is one of the main prevalent gastrointestinal multi-etiological disorders with many associated complications and adverse effects. Our aim was to develop safer antiulcer therapies based on methanol or ethyl acetate extracts of tubers and aerial parts from Cyperus alternifolius. METHODS Gastric ulceration was experimentally generated by administration of single oral doses of indomethacin (30 mg/kg) to fasted rats. The animals received methanol or ethyl acetate extracts of C. alternifolius tuber and methanol or ethyl acetate extracts of aerial parts at two dose levels (50 or 100 mg/kg). Ranitidine (50 mg/kg) was used as standard anti-ulcer drug. After 4 h, the ulcer number and the total ulcer score were determined and TNF-α was assessed. Also, pathological and histochemical examination for gastric mucosa were performed. The metabolome heterogeneity of the different extracts was explored using (UPLC-MS) aided by supervised pattern recognition, i.e., orthogonal partial least squares discriminate analysis (OPLS-DA). A second OPLS-DA model was employed to link the UPLC-MS derived metabolome of the different extracts to their antiulcer activity to identify activity mediating metabolites. RESULTS The extracts significantly reduced ulcer number, total ulcer score and TNF-α content in the stomach. Methanol or ethyl acetate extracts of tubers were most effective even more than ranitidine. In parallel, the histopathological examination showed an improvement of damaged mucosa. A high PAS reaction was observed in the treated groups indicating a relieve of the mucosal layer. A mechanistic clue of the C. alternifolius antiulcer potential was provided by the identification of its bioactive compounds using OPLS-DA. Both methanol extracts of tubers and aerial parts were more enriched in phenolic acids. The ethyl acetate extract of the aerial part was more abundant in two aldehydes. A mechanism of action was postulated based on their reported actions viz. α-carbonic anhydrase inhibition, anti-inflammatory and analgesic activity by its antioxidant activity and downregulation of several inflammatory mediators. CONCLUSION This is the first study to report on the antiulcer activity of C. alternifolius tubers with identification of the key bioactive compounds and the mode of action. Future phytochemical and biological evaluation of the identified bioactive compounds are needed to confirm the plant tubers as safer alternative or adjunct therapy compared to conventional antiulcer drugs.

Abstract
The objective of this current study is to search the impacts of furan and lycopene on a diabetic rat's heart. Diabetes increases prevalence with a sedentary lifestyle and obesity. Furan, a carcinogen, was detected in foods that had undergone thermal treatment. Two groups were formed, such as: the control and diabetic groups. Diabetic groups fall into four allocated groups: control, lycopene, furan, and furan + lycopene. The changes in malondialdehide levels, antioxidant enzymes' activities, and histopathology of the heart were pointed out. We observed that the changes in both the MDA level and the antioxidant enzymes' activities were due to diabetes. Furan-induced increment in MDA levels, but GST, CAT, SOD, and GPx activities showed a decrease. Lycopene influenced these changes positively. In terms of the pathological studies, changes were also observed in diabetic rats. The histological damage in the diabetic furan groups was found to be very serious. Lycopene was protective against furan that caused histopathological changes. Diabetes and furan resulted into heart damages in rats and lycopene showed preventive effects. But this was not a complete protection. PRACTICAL APPLICATIONS: Furan by product of chlorinated chemical compounds production and chemical processes including combustion, are virtually ubiquitous in the environment. Because of this, furan occur potential risk for human health. Furan is known to exist at higher levels in fatty foods, such as full-fat milk and dairy products, meat and eggs. They can accumulate in the fatty tissues of animals and humans. Diabetes increase in the prevalence of a sedentary lifestyle and obesity. Diabetes with furan-induced cardiotoxicity. Foods should not be heated over and over again, especially diabetic heart patients should stay away from this situation.

Abstract
Maternal stress during pregnancy is associated with an increased risk of psychopathology in offspring. Resident immune cells of the brain, microglia, may be mediators of prenatal stress and altered neurodevelopment. Here, we demonstrate that neither the exogenous pro-inflammatory cytokine, interleukin-1β (IL-1β), nor the glucocorticoid hormone, corticosterone, recapitulated the full effects of prenatal stress on the morphology of microglial cells in the cortical plate of embryonic mice; IL-1β effects showed greater similarity to prenatal stress effects on microglia. Unexpectedly, oil vehicle alone, which has antioxidant properties, moderated the effects of prenatal stress on microglia. Microglia changes with prenatal stress were also sensitive to the antioxidant, N-acetylcysteine, suggesting redox dysregulation as a mechanism of prenatal stress.

Abstract
Rice bran, one of the most abundant and valuable byproducts produced during the rice milling process, is of steadily growing interest in recent years due to its potential health benefits. Evidence is rapidly accumulating for the beneficial effects of nutraceuticals. However, the potential benefits of rice bran are found in several of its bioactive ingredients including oils, polysaccharides, proteins, and micronutrients. In addition, a significant advantage of rice bran is that it contains more than 100 antioxidants and several categories of bioactive phytonutrients, such as polyphenols, phytosterols, tocotrienols, γ-oryzanol, B vitamins, minerals, and trace minerals. As an immunomodulator, rice bran has beneficial constituents such as polysaccharides, proteins, and oils. Numerous studies also reported that potent antioxidants in rice bran included immune system enhancing compounds, such as phytosterols, polysaccharides, minerals and trace minerals including magnesium, selenium, zinc, vitamin E, omega-3 fatty acids and several other phytonutrients. We believe that this review will be a valuable resource for more studies on rice barn as a dietary source.

Abstract
The gastrointestinal (GI) mucosa provides the first protective barrier for digested food and xenobiotics, which are easily attacked by toxic substances. Nonsteroidal anti-inflammatory drugs, including aspirin, diclofenac, indomethacin, and ketoprofen, are widely used in clinical medicine, but these drugs may cause oxidative stress, leading to GI damage such as ulcers. Lansoprazol, omeprazole, and other clinical drugs are widely used to treat duodenal and gastric ulcers and have been shown to have multiple biological functions, such as antioxidant activity and the ability to upregulate antioxidant enzymes in vivo. Therefore, the reduction of oxidative stress may be an effective curative strategy for preventing and treating nonsteroidal anti-inflammatory drug induced ulcers of the GI mucosa. Phytochemicals, such as dietary phenolic compounds, phenolic acids, flavan-3-ols, flavonols, flavonoids, gingerols, carotenes, and organosulfur, are common antioxidants in fruits, vegetables, and beverages. A large amount of evidence has demonstrated that natural phytochemicals possess bioactivity and potential health benefits, such as antioxidant, anti-inflammatory, and antibacterial benefits, and they can prevent digestive disease processes. In this review, we summarize the literature on phytochemicals with biological effects, such as angiogenic, antioxidant, antiapoptotic, anti-inflammatory, and antiulceration effects, and their related mechanisms are also discussed.

Abstract
This study investigated possible role of U-II and its receptor expression in inflammation by using UTR agonist and antagonist in carrageenan induced acute inflammation. Rats were divided into 5 groups as (1) Healthy control, (2) Carrageenan control, (3) Carrageenan +Indomethacin 20mg/kg, orally, (4) Carrageenan +AC7954 (U-II receptor agonist, intraperitoneally) 30mg/kg and (5) Carrageenan +SB657510 (UTR antagonist, intraperitoneally) 30mg/kg. 1h after drug administration, carrageenan was injected. At the 3rd hour after carrageenan injection, agonist produced no effect while antagonist 63% anti-inflammatory effect respectively. UTR and UT-II expression increased in carrageenan induced paw tissue. Antagonist administration prevented the decrease in an antioxidant system and also capable to decrease TNF-α and IL-6 mRNA expressions. This study showed the role of urotensin II receptors in the physiopathogenesis of acute inflammatory response that underlying many diseases accompanied by inflammation.

Abstract
Silibinin, a major polyphenol in milk thistle, has been reported to have multiple pharmacological activities; therefore, there is an urgent need to well understand how silibinin works on inflammation-associated skin diseases. We herein designed silibinin on 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated skin inflammation to test its inhibitory effects. It was demonstrated that silibinin, applied topically onto mouse ears following TPA stimulation, effectively down-regulated the expressions of TPA-induced interleukin-1β (IL-1β), interleukin-6 (IL-6), necrosis factor-alpha (TNF-α) and cyclooxygenase-2 (COX-2) in a dose-dependent manner. Further mechanistic investigations indicated that silibinin suppressed the expression of IκB kinase (IKK) by inhibiting the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway, and thereby suppressing TPA-stimulated nuclear factor-κB (NF-κB) activation. Promisingly, silibinin, used for transdermal application, may be a potent naturally occurring anti-inflammatory agent for the prevention of inflammation-associated skin diseases.

Abstract
In vitro studies have been carried out to establish the nutritional differences between crude and refined vegetable oils; however, the impact of the consumption of these foods on metabolism, in particular the effect of buriti oil, needs to be further evaluated. The aim of this study was to evaluate the biochemical and murine parameters and the vitamin A and E status in young rats fed with diets supplemented with crude or refined buriti oil. The animals (n = 30) were randomized into three groups receiving diet added of soybean oil (control), crude buriti oil (CBO) and refined buriti oil (RBO) for 28 days. Rats fed with diet added of refined buriti oil (RBO) showed reduced total cholesterol (up to 60.27%), LDL (64.75%), triglycerides (55.47%) and enzyme aspartate transaminase (21.57%) compared to those fed with diet added of crude oil. Serum and hepatic retinol and tocopherol were higher by two to three times in CBO and RBO groups compared to the control group, but no differences were observed for murine parameters. The results indicate that buriti oil is an important source of the antioxidant vitamins A and E, and refined buriti oil is suggested as alternative to improve the lipid profile of healthy rats.

Abstract
Excessive UV-B radiation by sunlight produces inflammatory and oxidative damage of skin, which can lead to sunburn, photoaging, and cancer. This study evaluated whether nanoencapsulation improves the protective effects of rice bran oil against UVB radiation-induced skin damage in mice. Lipid-core nanocapsules containing rice bran oil were prepared, and had mean size around 200 nm, negative zeta potential (∼-9 mV), and low polydispersity index (<0.20). In order to allow application on the skin, a hydrogel containing the nanoencapsulated rice bran oil was prepared. This formulation was able to prevent ear edema induced by UVB irradiation by 60 ± 9%, when compared with a hydrogel containing LNC prepared with a mixture of medium chain triglycerides instead of rice bran oil. Protein carbonylation levels (biomarker of oxidative stress) and NF-κB nuclear translocation (biomarker of pro-inflammatory and carcinogenesis response) were reduced (81% and 87%, respectively) in animals treated with the hydrogel containing the nanoencapsulated rice bran oil. These in vivo results demonstrate the beneficial effects of nanoencapsulation to improve the protective properties of rice bran oil on skin damage caused by UVB exposure.

Clin Nutr 2015; 35:428-435. [PMID: 25818123 DOI: 10.1016/j.clnu.2015.03.006] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2015] [Revised: 03/09/2015] [Accepted: 03/10/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND AND AIMS Lycopene, the main antioxidant compound present in tomatoes, has high singlet oxygen- and peroxyl radicals-quenching ability, resulting in protection against oxidative damage in aerobic cell. Indomethacin is a nonsteroidal anti-inflammatory drug, and can promote oxidative damage in gastric tissue. The aim of this study was to investigate the protective effects of lycopene on an indomethacin-induced gastric ulcer model. METHODS A total of 42 adult male Wistar rats were divided into six groups of seven animals as follows: control, indomethacin, lansoprazole, lycopene 10 mg/kg, lycopene 50 mg/kg and lycopene 100 mg/kg. Gastric ulcers were induced by oral administration of indomethacin, after which the differing doses of lycopene were administered by oral gavage. The efficacy of lycopene was compared with lansoprazole. DNA damage of lymphocytes was measured by comet assay. Activities of superoxide dismutase, catalase and myeloperoxidase, as well as malondialdehyde and glutathione levels were determined in stomach tissue. This tissue was also taken for pathological investigations. The TUNEL method was used to detect apoptotic cells in paraffin sections. RESULTS The results showed that 100 mg/kg lycopene administration significantly decreased % Tail DNA and Mean Tail Moment in the gastric ulcer group, compared with the other treatment groups. This same dose of lycopene also significantly decreased high malondialdehyde level and myeloperoxidase activity, and increased the activity of antioxidant enzymes (with the exception of catalase) in tissue. Apoptosis rates in the stomachs of the rats correlated with the biochemical and histopathological findings. CONCLUSIONS These results indicated that lycopene might have a protective effect against indomethacin-induced gastric ulcer and oxidative stress in rats.

Abstract
CONTEXT Many scientific reports have shown the involvement of oxidative stress and inflammation as well as diminished gastroprotective substances in the pathogenesis of gastric lesions using various models. Therefore, treatment with antioxidants like tocopherol and tocotrienol may afford beneficial effects in attentuating the formation of the gastric lesions. OBJECTIVE The aim of this work was to summarize documented reports on the effects of vitamin E on various models of gastric lesion. METHODS A literature search was performed from databases in Medline (PubMed), Web of Science, ScienceDirect, and Googlescholar from June to December 2013. RESULTS AND CONCLUSION The potential roles of tocopherol and tocotrienol in modifying the effects of ulcerogenic agents are discussed in this review. The protective effects of the vitamin E might involve ameliorating oxidative stress and inflammation as well as restoration of endogenous gastroprotective substances. This vitamin has the potential to be used as a therapy for gastric mucosal injury.

Possible potentiation by certain antioxidants of the anti-inflammatory effects of diclofenac in rats. ScientificWorldJournal 2014; 2014:731462.

Abstract
In the present study, we investigated the potential beneficial impact of the addition of antioxidant supplements to diclofenac regimen in a model of carrageenan-induced paw. Rats were treated daily with antioxidants, that is, a-lipoic acid (50 mg/kg), selenium (2.5 mg/kg), vitamin C (1 g/kg), vitamin E (300 mg/kg), or zinc (25 mg/kg) on seven successive days and then received a single treatment with diclofenac or saline before carrageenan was injected to induce paw inflammation. The results indicated that these combinations did not significantly affect the percentage inhibition of paw edema caused by diclofenac alone; however, some combination treatments ameliorated signs of concomitant oxidative stress (such as alterations in plasma malondialdehyde (MDA) levels, hemolysate reduced glutathione levels, and erythrocytic superoxide dismutase enzyme activities) imparted by diclofenac alone. In some cases, few tested antioxidants in combination with diclofenac resulted in increased plasma levels of interleukin- (IL-) 6 and C-reactive protein (CRP). In conclusion, the results of these studies suggested to us that the added presence of natural antioxidants could be beneficial as standard anti-inflammatory therapeutics for a patient under diclofenac treatment, albeit that these effects do not appear to significantly build upon those that could be obtained from this common anti-inflammatory agent per se.

Abstract
Nonsteroidal anti-inflammatory drugs, such as ketoprofen, are generally used to treat pain and inflammation and as pyretic agents in clinical medicine. However, the usage of these drugs may lead to oxidative injury to the gastrointestinal mucosa. Camellia oil ( Camellia oleifera Abel.) is commonly used in Taiwan and China as cooking oil. Traditional remedies containing this oil exert beneficial health effects on the bowel, stomach, liver, and lungs. However, the effects of camellia oil on ketoprofen-induced oxidative gastrointestinal mucosal lesions remain unknown. The objective of this study was to evaluate the effect of camellia oil on ketoprofen-induced acute gastrointestinal ulcers. The results showed that treatment of Int-407 cells with camellia oil (50-75 μg/mL) not only increased the levels of heme oxygenase-1 (HO-1), glutathione peroxidase (GPx), and superoxide dismutase (SOD) mRNA expression but also increased vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE2) protein secretion, which served as a mucosal barrier against gastrointestinal oxidative injury. Moreover, Sprague-Dawley (SD) rats treated with camellia oil (2 mL/kg/day) prior to the administration of ketoprofen (50 mg/kg/day) successfully inhibited COX-2 protein expression, inhibited the production of interleukin-6 (IL-6) and nitrite oxide (NO), reversed the impairment of the antioxidant system, and decreased oxidative damage in the gastrointestinal mucosa. More importantly, pretreatment of SD rats with camellia oil strongly inhibited gastrointestinal mucosal injury induced by ketoprofen, which was proved by the histopathological staining of gastrointestinal tissues. Our data suggest that camellia oil exerts potent antiulcer effects against oxidative damage in the stomach and intestine induced by ketoprofen.

Abstract
Triptolide (TP) often causes adverse reactions in the gastrointestinal tract when it is administered orally. This study aimed to prepare and optimize triptolide-loaded solid lipid nanoparticles (TP-SLN) with reduced gastric irritation. The microemulsion technique was used to formulate TP-SLN employing a five-level central composite design (CCD) that was developed for exploring the optimum levels of three independent variables on particle size, encapsulation efficiency (EE) and drug loading (DL). Quadratic polynomial models were generated to predict and evaluate the three independent variables with respect to the three responses. The optimized TP-SLN was predicted to comprise fraction of lipid of 49.73%, surfactant to co-surfactant ratio of 3.25, and lipid to drug ratio of 55.27, which showed particle size of 179.8 ± 5.7 nm, EE of 56.5 ± 0.18% and DL of 1.02 ± 0.003% that were in good agreement with predicted values. In addition, the optimized nanoparticles manifested a sustained-release pattern in vitro and were stable during 3 h of incubation in simulated gastric fluids without significant size change and the majority (91%) of the drug was protected. Furthermore, the nanoparticles did not show obvious gastric irritation caused by oral administration of TP in rats.

Abstract
Gastroprotective effects of α-lipoic acid (ALA) against oxidative gastric damage induced by indomethacin (IND) have been investigated. All doses (50, 75, 100, 150, 200, and 300 mg/kg body weight) of ALA reduced the ulcer index with 88.2% to 96.1% inhibition ratio. In biochemical analyses of stomach tissues, ALA administration decreased the level of lipid peroxidation (LPO) and activities of myeloperoxidase (MPO) and catalase (CAT) in gastric tissues, which were increased after IND application. ALA also increased the level of glutathione (GSH) and activities of superoxide dismutase (SOD) and glutathione S-transferase (GST) that were decreased in gastric damaged stomach tissues. In conclusion, the gastroprotective effect of ALA could be attributed to its ameliorating effect on the antioxidant defense systems.

Abstract
The effect of consumption of fatty acids and selected nutrients, along with regular physical activity, on cardiovascular risk factors in rats was investigated.Male rats were divided into the seven groups: Group 1: regular food and drinking water, Group 2: same as Group. 1 + physical activity (whole body vibration; WBV), Group 3: same as Group. 2 + calcium, vitamin D, boron, Group 4: same as Group. 3 + canola oil, Group 5: same as Group. 3 + sunflower oil, Group 6: same as Group. 3 + mix of sunflower oil and canola oil, Group 7: same as Group. 3 + coconut oil. Rats were treated for 8 weeks, and analysis of the frozen plasmas was performed. A- Analysis between the treatment groups and control revealed that vibration training in Group 2 increased body weight (P = 0.04), plasma creatin kinase (CK), (P = 0.02), and estradiol (E2), (P = 0.03). Rats in Group 5 consumed less food and plasma levels of cholesterol and LDL-cholesterol (LDL-C) increased significantly (P = 0.02) in Group 6 and in Group 7 (p<0.05). B- Analysis of data among Group 4 - 7 (the oil consuming groups) and Group 3 revealed significant differences in cholesterol (Chol), LDL-C, HDL-cholesterol (HDL-C), triglycerides (TG), C- reactive protein (hs-CRP), estradiol (E2), atherogenic index (AI), and risk factor (RF), (p<0.05). In addition, plasma levels of testosterone (T) and free testosterone (FT) in Group 7 had a remarkable but non-significant increase. As a result of vibration training, a similar trend was observed for vitamin D in Group 2-7. The findings show that WBV is effective in improving health status by influencing cardiovascular disease (CVD) risk factors. Moreover, canola oil and sunflower oil, separately, showed beneficial impacts on CVD risk factors; whereas their combination had negative impacts on lipid profile. Coconut oil revealed to be efficient to provide health benefits in terms of CVD treatments.

Abstract
High consumption of polyunsaturated fatty acids, such as sunflower oil has been associated to beneficial effects in plasma lipid profile, but its role on inflammation and insulin resistance is not fully elucidated yet. We evaluated the effect of sunflower oil supplementation on inflammatory state and insulin resistance condition in HFD-induced obese mice. C57BL/6 male mice (8 weeks) were divided in four groups: (a) control diet (CD), (b) HFD, (c) CD supplemented with n-6 (CD + n-6), and (d) HFD supplemented with n-6 (HFD + n-6). CD + n-6 and HFD + n-6 were supplemented with sunflower oil by oral gavage at 2 g/Kg of body weight, three times per week. CD and HFD were supplemented with water instead at the same dose. HFD induced whole and muscle-specific insulin resistance associated with increased inflammatory markers in insulin-sensitive tissues and macrophage cells. Sunflower oil supplementation was not efficient in preventing or reducing these parameters. In addition, the supplementation increased pro-inflammatory cytokine production by macrophages and tissues. Lipid profile, on the other hand, was improved with the sunflower oil supplementation in animals fed HFD. In conclusion, sunflower oil supplementation improves lipid profile, but it does not prevent or attenuate insulin resistance and inflammation induced by HFD in C57BL/6 mice.

Anti-inflammatory and antinociceptive effects of salbutamol on acute and chronic models of inflammation in rats: involvement of an antioxidant mechanism. Mediators Inflamm 2012; 2012:438912.

Abstract
The possible role of β-2 adrenergic receptors in modulation of inflammatory and nociceptive conditions suggests that the β-2 adrenergic receptor agonist, salbutamol, may have beneficial anti-inflammatory and analgesic effects. Therefore, in this study, we induced inflammatory and nociceptive responses with carrageenan-induced paw edema or cotton-pellet-induced granuloma models, both of which result in oxidative stress. We hypothesized that salbutamol would prevent inflammatory and nociceptive responses by stimulating β-2 adrenergic receptors and the prevention of generation of ROS during the acute inflammation process in rats. Both doses of salbutamol used in the study (1 and 2 mg/kg) effectively blocked the acute inflammation and inflammatory nociception induced by carrageenan. In the cotton-pellet-induced granuloma test, both doses of salbutamol also significantly decreased the weight of granuloma tissue on the cotton pellets when compared to the control. Anti-inflammatory and analgesic effects of salbutamol were found to be comparable with those of indomethacin. Salbutamol decreased myeloperoxidase (MPO) activity and lipid peroxidation (LPO) level and increased the activity of superoxide dismutase (SOD) and level of glutathione (GSH) during the acute phase of inflammation. In conclusion, salbutamol can decrease acute and chronic inflammation, possibly through the stimulation of β-2 adrenergic receptors. This anti-inflammatory effect may be of significance in asthma treatment, where inflammation also takes part in the etiopathology. This study reveals that salbutamol has significant antioxidative effects, which at least partially explain its anti-inflammatory capabilities. These findings presented here may also shed light on the roles of β-2 adrenergic receptors in inflammatory and hyperalgesic conditions.

Abstract
D-002, a mixture of higher aliphatic beeswax alcohols, produces gastroprotective and antioxidant effects. To investigate the gastroprotective effect of D-002 against indomethacin-induced ulcers, oxidative variables and myeloperoxidase (MPO) activity in the rat gastric mucosa were examined. Rats were randomized into six groups: a negative vehicle control and five indomethacin (50 mg/kg) treated groups, comprising a positive control, three groups treated orally with D-002 (5, 25 and 100 mg/kg) and one group with omeprazole 20 mg/kg intraperitoneally (ip). The contents of malondialdehyde (MDA), protein carbonyl groups (PCG), hydroxyl radical generation and catalase (CAT), glutathione peroxidase (GSH-PX), superoxide dismutase (SOD) and MPO enzyme activities in the rat gastric mucosa were assessed. Indomethacin increased the content of MDA and PCG, the generation of *OH radical and MPO enzyme activity, while it decreased the CAT, GSH-PX and SOD activities as compared to the negative controls. D-002 (5-100 mg/kg) significantly and dose-dependently reduced indomethacin-induced ulceration to 75 %. Also, D-002 decreased the content of MDA and PCG, the generation of hydroxyl radicals and MPO activity as compared to the positive controls. The highest dose of D-002 (100 mg/kg) increased significantly GSH-PX and SOD activities, while all doses used increased CAT activities. Omeprazole 20 mg/kg, the reference drug, reduced significantly the ulcers (93 %), MDA and PCG, the generation of hydroxyl radicals and MPO activity, and increased the CAT, GSH-PX and SOD activities. D-002 treatment produced gastroprotective effects against indomethacin-induced gastric ulceration, which can be related to the reduction of hydroxyl radical generation, lipid peroxidation, protein oxidation and MPO activity, and to the increase of the antioxidant enzymes activities in the rat gastric mucosa.

Abstract
α-Lipoic acid (ALA) has been termed the 'ideal' antioxidant, a readily absorbed and bioavailable compound capable of scavenging a number of free radicals, and it has been used for treating diseases in which oxidative stress plays a major role. The present study was designed to gain a better understanding for the positive effects of ALA on the models of acute and chronic inflammation in rats, and also determine its anti-oxidative potency. In an acute model, three doses of ALA (50, 100 and 200 mg/kg) and one dose of indomethacin (25 mg/kg) or diclofenac (25 mg/kg) were administered to rats by oral administration. The paw volumes of the animals were calculated plethysmometrically, and 0·1 ml of 1 % carrageenan (CAR) was injected into the hind paw of each animal 1 h after oral drug administration. The change in paw volume was detected as five replicates every 60 min by plethysmometry. In particular, we investigated the activities of catalase, superoxide dismutase (SOD), glutathione S-transferase (GST), glutathione peroxidase (GPx), glutathione reductase (GR), inducible NO synthase (iNOS) and myeloperoxidase (MPx), and the amounts of lipid peroxidation (LPO) or total GSH in the paw tissues of CAR-injected rats. We showed that ALA exhibited anti-inflammatory effects on both acute and chronic inflammations, and a strongly anti-oxidative potency on linoleic acid oxidation. Moreover, the administration of CAR induced oedema in the paws. ALA significantly inhibited the ability of CAR to induce: (1) the degree of acute inflammation, (2) the rise in MPx activity, (3) the increases of GST and iNOS activities and the amount of LPO and (4) the decreases of GPx, GR and SOD activities and the amount of GSH. In conclusion, these results suggest that the anti-inflammatory properties of ALA, which has a strong anti-oxidative potency, could be related to its positive effects on the antioxidant system in a variety of tissues in rats.

Abstract
Three Hypericum perforatum L., Hypericaceae (St. John’s Wort) oil extracts (HPE) were prepared according to the prescriptions from traditional medicine – fresh flowering tops were macerated in three different vegetable oils: sunflower (E1), olive (E2) and palm oil (E3) for 40 days, exposed to the sunlight. The aim of the study was to investigate the gastroprotective activity of the obtained extracts in respect to their quercetin content. HPLC analysis confirmed the presence of quercetin in all of the investigated HPEs, but in different amounts: 15.1, 5.8 and 21.7 μg/mL in E1, E2, and E3, respectively. Gastroprotective activity was evaluated using cold-restraint stress (CRS) induced rat gastric mucosa lesions test. All of the HPEs showed gastroprotective activity, which was close to that achieved by the one of the most studied anti-ulcer flavonoids, quercetin [percentages of inhibition of ulcer index (UI) were 35, 62 and 40 % in E1, E2 and E3, respectively]. Contrary to the lowest quercetin content, HPE prepared with olive oil (E2) offered the highest protection against gastric damaging action of CRS. It may be assumed that this is due to other constituents of E2, which probably play an additional role in complex gastroprotective activity.
