Abstract
Ulcerative colitis (UC) is an inflammatory disease of the large intestine that is characterized by diarrhea, bloody stools, abdominal pain and mucosal ulceration. UC is treated with nonsteroidal anti-inflammatory drugs, corticosteroids or immunosuppressants, but long-term use of these drugs can cause adverse effects. Arum maculatum is used as a traditional treatment for digestive system disorders, but its use for treatment of UC has not been investigated rigorously. We investigated the possible protective effect of a methanol extract of A. maculatum against dextran sulfate sodium (DSS) induced experimental UC in rats. Total phenolic and flavonoid contents of the extract were 32.919 ± 1.125 mg gallic acid equivalent (GAE)/g and 52.045 ± 7.902 µg rutin equivalent (RE)/mg, respectively. The half-maximal inhibitory concentration (IC50) for the extract was 105.76 µg/ml according to the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity assay. Effects of A. maculatum extract on UC induced by DSS were assessed both macroscopically and histologically. We also investigated effects of A. maculatum extract on malondialdehyde (MDA) levels and the oxidative stress index (OSI) in normal rats and rats with UC. We found that treatment with A. maculatum extract protected the colon against DSS induced UC in a dose-dependent manner.

Şen A, Özbeyli D, Teralı K, Göger F, Yıldırım A, Ertaş B, Doğan A, Bitiş L, Şener G. Protective effects of Rubus tereticaulis leaves ethanol extract on rats with ulcerative colitis and bio-guided isolation of its active compounds: A combined in silico, in vitro and in vivo study. Chem Biol Interact 2023; 369:110263. [PMID: 36375516 DOI: 10.1016/j.cbi.2022.110263] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 11/01/2022] [Accepted: 11/11/2022] [Indexed: 11/13/2022]
Abstract
The aim of this study was to evaluate the therapeutic effect of active ethanol extract obtained from the leaves of Rubus tereticaulis (RTME) against colitis, and to purify major compounds from this extract by bioassay-directed isolation. Rats with colitis induced via intra-rectal acetic acid administration (5%, v/v) received RTME or sulfasalazine for three consecutive days. On day four, all rats were decapitated, and the colonic tissue samples were collected for macroscopic score, colon weight, reduced glutathione (GSH), myeloperoxidase (MPO), and malondialdehyde (MDA) analyses. The active compounds and chemical composition of RTME were determined by bio-guided isolation and LC-MS/MS, respectively. Compared to the colitis group, the rats treated with RTME displayed significantly lowered macroscopic scores and colon wet weights (p < 0.001). These effects were confirmed biochemically by a decrease in colonic MPO activity (p < 0.001), MDA levels (p < 0.001), and an increase in GSH levels (p < 0.001). Kaempferol-3-O-β-d-glucuronide (RT1) and quercetin-3-O-β-d-glucuronide (RT2) were found to be the major compounds of RTME, as evidenced by in vitro anti-inflammatory and antioxidant activity-guided isolation. Their anti-inflammatory/antioxidant activities were also predicted by docking simulations. Additionally, quinic acid, 5-caffeoylquinic acid, quercetin pentoside, quercetin glucoside, quercetin-3-O-β-d-glucuronide, kaempferol-3-O-β-d-glucuronide, and kaempferol rutinoside were identified in RTME via using LC-MS/MS. RT2, along with other compounds, may be responsible for the observed protective action of RTME against colitis. This study represents the first report on the beneficial effects of RTME in an experimental model of colitis and highlights the potential future use of RTME as a natural alternative to alleviate colitis.

Abstract
ETHNIC PHARMACOLOGICAL RELEVANCE Plant materials are used as complementary and alternative therapies all over the world for the treatment of various diseases. Ulcerative colitis (UC), a chronic nonspecific inflammatory bowel disease listed as one of the modern refractory diseases by the World Health Organization, has a long course, is challenging to cure, and is prone to cause cancer. Recent years have witnessed a growing trend of applying traditional Chinese medicine (TCM) to UC. AIM OF THIS REVIEW This review presents an overview of the pathogenesis of UC and reports the therapeutic effect of TCM on UC (including TCM prescriptions, single TCM, and treatments using TCM ingredients) to provide a theoretical basis for the use of TCM in treating UC. METHODS We performed a collection and collation of relevant scientific articles from different scientific databases regarding TCM and its usefulness in treating UC. In this paper, the therapeutic effect of TCM is summarized and analyzed according to the existing experimental and clinical research. RESULTS There are positive signs that TCM primarily regulates inflammatory cytokines, intestinal flora, and the immune system, and also protects the intestinal mucosa. Hence, it can play a role in treating UC. CONCLUSION TCM has a definite curative effect in the treatment of UC. It can alleviate and treat UC in a variety of ways. We should take syndrome differentiation and treatment differentiation as the basis. With the help of modern medicine, TCM's clinical curative effects can be enhanced for the treatment of UC.

Yiyi Fuzi Baijiang Decoction Alleviates Ulcerative Colitis Partly by Regulating TLR4-Mediated PI3K/Akt and NF- κB Pathways. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8780514. [PMID: 35211182 PMCID: PMC8863463 DOI: 10.1155/2022/8780514] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Accepted: 01/12/2022] [Indexed: 12/28/2022]
Abstract
Yiyi Fuzi Baijiang Decoction (YFBD), an ancient prescription developed by the ancient Chinese physician, Zhang Zhongjing, has shown remarkable effects in treating ulcerative colitis (UC). However, there are few studies on its mechanism. This study was designed to explore the potential mechanism of YFBD in treating UC. The principal ingredients of YFBD were analyzed using high-performance liquid chromatography (HPLC). Dextran sulfate sodium- (DSS-) induced mice and lipopolysaccharide- (LPS-) stimulated RAW264.7 cells were used in the study. The body weight and disease activity index (DAI) of mice were recorded and analyzed for 10 days. After sacrifice, the colonic tissues were harvested. The colon length was measured, and the histopathological changes were observed by hematoxylin and eosin staining. The levels of inflammatory cytokines in mice colons and RAW246.7 cells were determined by real-time quantitative PCR and immunofluorescence. The effects of YFBD on the TLR4-mediated PI3K/Akt and NF-κB pathways were determined by western blot analysis. HPLC identified five compounds in YFBD: chlorogenic acid, caffeic acid, benzoylmesaconine, benzoyl aconitine, and quercetin. YFBD alleviated weight loss, colon shortening, and colonic histopathological lesion in mice. Meanwhile, it decreased the DAI and histological score of mice with UC. In addition, YFBD remarkably decreased the levels of interleukin- (IL-) 6, IL-1β, and tumor necrosis factor (TNF)-α in the colons of DSS-induced mice and LPS-stimulated RAW246.7 cells. Furthermore, the expression of key proteins in TLR4-mediated PI3K/Akt and NF-κB pathways significantly decreased with YFBD treatment. In conclusion, YFBD had protective effects on mice with UC, which was in part related to its anti-inflammatory effects and downregulation of TLR4-mediated PI3K/Akt and NF-κB pathways.

Abstract
Aim: To evaluate the protective effects of Platycladi Cacumen Carbonisata-derived nanoparticles (PCC-NPs) against 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced ulcerative colitis (UC) in rats. Methods: This study developed and characterized novel PCC-NPs synthesized by a green and simple pyrolysis process using Platycladi Cacumen (PC) as the sole precursor. The UC model prepared with rectal instillation of TNBS was used to evaluate the potential efficacy of PCC-NPs, and the underlying mechanisms were preliminarily explored from the perspective of anti-inflammatory and antioxidative stress for the first time. Results: PCC-NPs exhibited low cytotoxicity, good dispersibility and copious surface functional groups. Nanoparticles with diameters ranging from 40-60 nm mainly manifested a therapeutic effect by downregulating tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6) and upregulating interleukin-10 (IL-10). In addition, PCC-NPs relieved colon injury by inhibiting myeloperoxidase (MPO) activity, limiting the release of malondialdehyde (MDA) and increasing the activity of superoxide dismutase (SOD). Conclusion: Green synthetic PCC-NPs is a potential candidate as a complementary drug for intestinal inflammation of inflammatory bowel disease, and its regulatory mechanisms may be to balance the levels of pro-/anti-inflammatory cytokines and improve resistance to oxidative stress.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease with limited therapeutic management approaches. The present study evaluated the potential therapeutic impact of betulin on acetic acid (AA)-induced UC in rats. UC was induced by intracolonic instillation of AA (3% v/v). Rats were treated with betulin (8 mg/kg, I.P., once daily) four days post AA instillation and for 14 consecutive days. Betulin attenuated AA-induced UC as evidenced by retracted macroscopic scores, serum CRP titre and LDH activity, attenuated histopathological hallmarks of UC including mucosal necrosis, haemorrhage, congestion and inflammatory cells infiltration. Moreover, betulin dampened UC-associated colonic inflammatory load with modulation of TLR4/NF-kB axis and reduction in colonic inflammatory cytokines; TNF-α, IL1β and IL-6. Nevertheless, betulin suppressed colonic apoptosis with reduced colonic caspase-3 and caspase-8 expression. The current findings confirm a beneficial therapeutic impact of betulin against UC. The prospective underlying mechanisms include down-regulation of TLR4/NF-κB and the subsequent downstream signalling pathways.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) is an inflammatory disorder of the colon. Garcinia mangostana Linn. (GM) has been traditionally used for its anti-inflammatory and antioxidant activities. AIM OF THE STUDY The effects of GM and its bioactive constituent α-mangostin on dextran sulfate sodium (DSS)-induced UC in mice were investigated. MATERIALS AND METHODS Adult ICR mice (n = 63) were pretreated with ethanolic GM extract at 40, 200, and 1000 mg/kg/day (GM40, GM200, and GM1000), α-mangostin at 30 mg/kg/day, or sulfasalazine at 100 mg/kg/day (SA) for 7 consecutive days. On days 4-7, UC was induced in the mice by the oral administration of DSS (40 kDa, 6 g/kg/day), while control mice received distilled water. The UC disease activity index (DAI) and histological changes were recorded. The activities of myeloperoxidase, catalase, and superoxide dismutase, and the levels of reactive oxygen species (ROS), nitric oxide (NO), and malondialdehyde (MDA) were determined. The mRNA expression of inflammatory related genes including proinflammatory cytokine Tnf-α, Toll-like receptor (Tlr-2), adhesion molecules (Icam-1 and Vcam-1), and monocyte chemoattractant protein (Mcp-1) were evaluated. RESULTS Treatment with GM or α-mangostin decreased the UC DAI and protected against colon shortening and spleen and kidney enlargement. GM and α-mangostin prevented histological damage, reduced mast cell infiltration in the colon, and decreased myeloperoxidase activity. GM and α-mangostin increased catalase and superoxide dismutase activity and decreased ROS, NO, and MDA production. GM downregulated mRNA expression of Tnf-α, Tlr-2, Icam-1, Vcam-1, and Mcp-1. CONCLUSIONS GM and α-mangostin attenuated the severity of DSS-induced UC via anti-inflammatory and antioxidant effects. Therefore, GM is a promising candidate for development into a novel therapeutic agent for UC.

Abstract
Oleuropein is one of the main phenolic secoiridoid of the olive leaf extract, which is known for its antioxidant and anti-inflammatory effects. The main objective of the present study was to investigate the effectiveness of oleuropein in the ulcerative colitis treatment. An experimental study was designed on rats, which were divided into three groups, group 1 (normal control), group 2 (induced for ulcerative colitis and untreated), and group 3 (induced for ulcerative colitis and treated with oleuropein). Colonic tissue samples were collected from all studied groups and the oxidative stress and antioxidant activity were assessed by evaluating malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), myeloperoxidase (MPO), and nitric oxide (NO) levels. The expression levels of pro-inflammatory cytokines such as IL-1β, TNF-α, IL-10, COX-2, iNOS, TGF-β1, MCP-1, and NF-κB, the pro-apoptotic gene Bax, and the anti-apoptotic gene Bcl2 were assessed in colon tissues to evaluate the effectiveness of oleuropein treatment. Oleuropein was effective on reducing the mortality rate and disease activity index. Oleuropein caused a significant reduction in colon MDA, MPO, and NO levels and a significant elevation in SOD, CAT, and GPX levels and induced the down regulation of analyzed proinflammatory cytokines. Also, downregulation of Bax and upregulation of Bcl2 were observed as a result of oleuropein treatment in comparison with untreated acetic acid induced ulcerative colitis group. Oleuropein showed intestinal anti-inflammatory, antioxidant, and anti-apoptotic effects in ulcerative colitis experimental model.

Abstract
Background and Objective This study was aimed to elucidate the molecular mechanism of Momordica charantia (MCh), along with a standard drug prednisolone, in a rat model of colitis induced by trinitrobenzene sulfonic acid (TNBS). Methods After the induction of the experimental colitis, the animals were treated with MCh (4 g/kg/day) for 14 consecutive days by intragastric gavage. The colonic tissue expression levels of C-C motif chemokine ligand 17 (CCL-17), interleukin (IL)-1β, IL-6, IL-23, interferon-γ (IFN-γ), nuclear factor kappa B (NF-kB), and tumor necrosis factor-α (TNF-α), were determined at both mRNA and protein levels to estimate the effect of MCh. Besides, colonic specimens were analyzed histopathologically after staining with hematoxylin and eosin. Results The body weights from TNBS-instigated colitis rats were found to be significantly lower than untreated animals. Also, the IFN-γ, IL-1β, IL-6, Il-23, TNF-α, CCL-17, and NF-kB mRNA and protein levels were increased significantly from 1.86-4.91-fold and 1.46-5.50-fold, respectively, in the TNBS-instigated colitis group as compared to the control. Both the MCh and prednisolone treatment significantly reduced the bodyweight loss. It also restored the induced colonic tissue levels of IL-1β, IL-6, IFN-γ, and TNF-α to normal levels seen in untreated animals. These results were also supported with the histochemical staining of the colonic tissues from both control and treated animals. Conclusion The presented data strongly suggests that MCh has the anti-inflammatory effect that might be modulated through vitamin D metabolism. It is the right candidate for the treatment of UC as an alternative and complementary therapeutics.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Guchang Zhixie Wan (GC) is a traditional Chinese patent medicine used in the treatment of colitis in clinical trials. Though the notable effect of GC on colitis, the concrete mechanism of GC remain elusive. Emerging evidence showed that the imbalances of inflammatory cytokines and gut microbiota were both closely related to the initiation and progression of colitis. AIM OF THE STUDY To elucidate the relationship between the protective effects of GC on colitis and gut microbiota. MATERIALS AND METHODS Male Kunming (KM) mice were enrolled in our work to establish colitis model induced by dextran sulfate sodium (DSS). The colitis mice were randomly divided into different groups and treated orally with 125 mg/kg of sulfasalazine (positive control) and 25, 50, 100 mg/kg of GC for 7 days, respectively. Inflammation cytokines of IL-1β, IL-4, IL-6, IL-8, IL-11, IL-12 and TNF-α were detected by ELISA analysis and the histological changes were detected by H&E staining. Gut microbiota diversity was analyzed by 16S rDNA sequencing. Metagenomes analysis were also conducted to reflect the protective effects of GC on colitis. RESULTS The results of CAS (Clinical Activity Score) confirmed the protective effects of GC on colitis. After administration of GC, the levels of pro-inflammatory cytokines IL-1β, IL-6, IL-8, IL-11, IL-12 and TNF-α were all decreased while the anti-inflammatory cytokines IL-4 was slightly increased, indicating that GC could down regulate pro-inflammatory cytokines. H&E staining revealed that GC could improve the histopathological structure of the colon tissue. The results of 16S rDNA sequences analysis showed that GC could decrease the relative abundance of Turicibacter and increase the relative abundance of Ruminococcaceae_UCG-005. CONCLUSION GC greatly improve the health condition of colitis mice induced by DSS through improving the imbalances of inflammatory cytokines and gut microbiota.

Abstract
Averrhoa carambola is commonly known as star fruit because of its peculiar shape, and its fruit is a rich source of minerals and vitamins. It is also used in traditional medicines in countries such as India, China, the Philippines, and Brazil for treating various ailments, including fever, diarrhea, vomiting, and skin disease. Here, we present the first draft genome of the Oxalidaceae family, with an assembled genome size of 470.51 Mb. In total, 24,726 protein-coding genes were identified, and 16,490 genes were annotated using various well-known databases. The phylogenomic analysis confirmed the evolutionary position of the Oxalidaceae family. Based on the gene functional annotations, we also identified enzymes that may be involved in important nutritional pathways in the star fruit genome. Overall, the data from this first sequenced genome in the Oxalidaceae family provide an essential resource for nutritional, medicinal, and cultivational studies of the economically important star-fruit plant.

Abstract
Nature is a rich source of natural drug-like compounds with minimal side effects. Phytochemicals
better known as “Natural Products” are found abundantly in a number of plants. Since time immemorial, spices
have been widely used in Indian cuisine as flavoring and coloring agents. Most of these spices and condiments
are derived from various biodiversity hotspots in India (which contribute 75% of global spice production) and
form the crux of India’s multidiverse and multicultural cuisine. Apart from their aroma, flavor and taste, these
spices and condiments are known to possess several medicinal properties also. Most of these spices are mentioned
in the Ayurveda, the indigenous system of medicine. The antimicrobial, antioxidant, antiproliferative,
antihypertensive and antidiabetic properties of several of these natural products are well documented in
Ayurveda. These phytoconstituemts are known to act as functional immunoboosters, immunomodulators as well
as anti-inflammatory agents. As anticancer agents, their mechanistic action involves cancer cell death via induction
of apoptosis, necrosis and autophagy. The present review provides a comprehensive and collective update
on the potential of 66 commonly used spices as well as their bioactive constituents as anticancer agents. The
review also provides an in-depth update of all major in vitro, in vivo, clinical and pharmacological studies done
on these spices with special emphasis on the potential of these spices and their bioactive constituents as potential
functional foods for prevention, treatment and management of cancer.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 248:112322. [PMID: 31644942 DOI: 10.1016/j.jep.2019.112322] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 10/04/2019] [Accepted: 10/16/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The ethnobotanical studies conducted in Turkey and other countries have revealed that Cornus mas L., from the family Cornaceae have been used against stomachache, diarrhea and colitis. AIM OF THE STUDY The objective the present study is to determine the possible activity of C. mas in experimentally induced ulcerative colitis in rats and to identify its phytochemical feature. MATERIALS AND METHODS 2,4,6-Trinitrobenzene sulfonic acid-induced colitis model was induced in rats. The rats were orally treated with different doses (50, 100, 200 and 400 mg/kg) of C. mas 80% methanol extract for 14 days. Increase in body weight, consumed amount of feed, form of the stool, presence of rectal prolapse were followed every day. At the end of the experiment, colon tissues were removed and wet weights for each animal were measured and colon damages were scored. Total antioxidant and total oxidant status, cytokine (TNF-α and IL-1β) and protein levels of colon tissues were evaluated and histopathological analyses were carried out. After the detection of the effective dose as 400 mg/kg, the aqueous methanol extract was fractionated by using liquid-liquid fractionation technique and the sub-extracts were also tested for in vivo biological activities. High Performance Liquid Chromatography analyses were conducted to determine the phytochemical profile of the active crude extract and n-butanol sub-extract. RESULTS Amount of feed consumed per day and increase in body weight were the lowest in the control group, while those values were determined to be the highest in 80% methanol extract (at 400 mg/kg dose), n-butanol sub-extract and reference groups. Following colitis induction, it was determined that the fecal form was yellow-slippery in all groups and returned to normal after the treatment with C. mas extracts. Rectal prolapse score was less in the extract (400 mg/kg) and n-butanol sub-extract treated groups. Total antioxidant, total oxidant status, cytokine and protein levels were found to be in parallel with macroscopic findings. 80% methanol extract (400 mg/kg) and n-butanol sub-extract provided the best healing according to the wet weight measurements and colon damage scoring performed on the removed colon tissues. These findings supported the results of histopathological analysis. According to the chromatographic analysis, ellagic acid was determined in both extracts and its amount was quantified. CONCLUSIONS The present study has verified the ethnomedical use of C. mas for the treatment of ulcerative colitis.

Abstract
Background Ulcerative colitis is a chronic mucosal inflammation of the large intestine mainly affecting the colon and rectum. The lack of effective and safe therapeutic agents led to the identification of new therapeutic agents to effectively manage the symptoms and complications of ulcerative colitis. The present study aimed to evaluate the protective effect of sodium benzoate in acetic acid-induced ulcerative colitis in rats. Methods Infusion of 3% acetic acid in the colon through the rectum was done to construct a rat model of ulcerative colitis. After 5 days of infusion, macroscopic, biochemical, and histopathological examinations and disease activity scoring of the colon were done to assess colonic damage. Results Acetic acid infusion resulted in severe inflammation in the colon assessed macroscopically and histopathologically. Moreover, it also led to increase in myeloperoxidase (MPO) and reduction in glutathione (GSH) levels. In the present study, repeated administration of sodium benzoate (400 and 800 mg/kg i.p.) and sulfasalazine (500 mg/kg orally) for 7 days, i.e. 2 days before and continued for 5 days after acetic acid infusion, significantly attenuated macroscopic damage and disease activity score as compared to disease control. Further, it also significantly reduced the levels of MPO and enhanced colonic levels of reduced GSH. However, the lower dose of sodium benzoate (200 mg/kg) did not show sufficient protective effect in acetic acid-induced ulcerative colitis. Further, sodium benzoate per se did not show any effect in normal rats. Conclusions The observed protective effect of sodium benzoate may be due to its antioxidant and anti-inflammatory activities in an ulcerative colitis model.

Abstract
Ulcerative colitis is a common intestinal inflammatory disease characterized by upregulation of pro-inflammatory cytokines and oxidative stress. Zeaxanthin is a nutritional carotenoid that belongs to the xanthophyll family of pigments. It exerts potent anti-inflammatory and antioxidative effects. The present study aimed to evaluate the effect of zeaxanthin on acetic acid-induced ulcerative colitis in rats. Rats were randomly categorized into five groups: control, zeaxanthin, acetic acid, acetic acid + zeaxanthin, and acetic acid + prednisolone groups. Zeaxanthin (50 mg/kg/day) or prednisolone (5 mg/kg/day) was orally administered for 14 days before induction of ulcerative colitis. On the 15th day, colitis was induced by transrectal administration of 3% acetic acid. The rats were sacrificed 24 h after rectal instillation and their colon tissues were examined. Pretreatment with zeaxanthin significantly reduced disease activity index, wet colon weight, ulcer area, macroscopic scores, and histological changes. Zeaxanthin also effectively downregulated the levels of myeloperoxidase and malondialdehyde, upregulated the enzymatic activity of superoxide dismutase and catalase, and raised glutathione levels. With regard to anti-inflammatory mechanisms, zeaxanthin suppressed tumor necrosis factor-alpha, interferon-gamma, interleukin-6, interleukin-1 beta, and nuclear transcription factor kappa B levels, and inhibited nitric oxide synthase and cyclooxygenase-2 protein expression. Our results indicate that oral administration of zeaxanthin ameliorates acetic acid-induced colitis in rats via antioxidative effects and modulation of pro-inflammatory cytokine and mediator activity. Therefore, zeaxanthin may be an effective therapeutic candidate for the treatment of ulcerative colitis.

Abstract
Inflammatory bowel disease (IBD) is a serious health concern among western societies. The disease is also on the rise in some East Asian countries and in Australia. Health professionals and dietitians around the world are facing an unprecedented challenge to prevent and control the increasing prevalence of IBD. The current therapeutic strategy that includes drugs and biological treatments is inefficient and are associated with adverse health consequences. In this context, the use of natural products is gaining worldwide attention. In vivo studies and clinical evidence suggest that well-planned dietary regimens with specific nutrients can alleviate gastrointestinal inflammation by modulating inflammatory cytokines, such as tumor necrosis factor α (TNF-α), interleukin 1 (IL-1), IL-6, IL-1β, and IL-10. Alternatively, the avoidance of high-fat and high-carbohydrate diets is regarded as an effective tool to eliminate the causes of IBD. Many functional foods and bioactive components have received attention for showing strong therapeutic effects against IBD. Both animal and human studies suggest that bioactive functional foods can ameliorate IBD by downregulating the pro-inflammatory signaling pathways, such as nuclear factor κB, STAT1, STAT6, and pro-inflammatory cytokines, including IL-1β, IL-4, IL-6, COX-2, TNF-α, and interferon γ. Therefore, functional foods and diets have the potential to alleviate IBD by modulating the underlying pathogenic mechanisms. Future comprehensive studies are needed to corroborate the potential roles of functional foods and diets in the prevention and control of IBD.

Abstract
Inflammatory bowel disease (IBD) is a notable health problem and may considerably affect the quality of human life. Previously, the protective roles of tryptanthrin (TRYP) against dextran sulfate sodium (DSS) induced colitis has been proved, but the concrete mechanism remained elusive. It has been suggested that TRYP could diminish the weight loss and improve the health conditions of mice with DSS induced colitis. Hematoxylin and eosin staining revealed that TRYP could improve the histopathological structure of the colon tissue. Two signaling pathways (TNF-α/NF-κBp65 and IL-6/STAT3) were investigated using immunochemistry and western blot. The detected concentrations of the two cytokines TNF-α and IL-6 showed that their levels decreased after TRYP treatment of the colitis. The protein expression level of NF-κBp65 in cytoplasm increased after TRYP treatment of the induced colitis. However, the protein level of NF-κBp65 in the nucleus decreased after administration of TRYP. The expression level of IκBα, the inhibitory protein of NF-κBp65, was tested and the results suggested that TRYP could inhibit the degradation of IκBα. The phosphorylation level of STAT3 was inhibited by TRYP and the expression level of STAT3 and p-STAT3 decreased after administration of TRYP. We conclude that TRYP improves the health condition of mice with DSS induced colitis by regulating the TNF-α/NF-κBp65 and IL-6/STAT3 signaling pathways via inhibiting the degradation of IκBα and the phosphorylation of STAT3.

Abstract
Diclofenac is a Non-Steroidal Anti-inflammatory drug which is used as an analgesic. It is known to cause heptotoxicity on over dose and long term usage. Madhuca longifolia is an evergreen tree found widely in India that is known to have several ethnomedical uses. The aim of our study is to evaluate the beneficial effect of the aqueous leaf extract of M. longifolia against diclofenac-induced toxicity. Rats were dived into five groups of six rats each. Group-I was normal control. Group-II was administered with diclofenac (50 mg/kg. b.w./day, i.p) on 4th and 5th day. Group-III rats were treated with aqueous leaf extract of M. longifolia (500 mg/kg b.w./day, oral) for 5 consecutive days and diclofenac (50 mg/kg. b.w./day, i.p) was given on 4th and 5th day. Silymarin (25 mg/kg. b.w./day, oral) was used as standard drug which was given to the rats of group-IV along with diclofenac on 4th and 5th day. Aqueous leaf extract of M. longifolia (500 mg/kg b.w./day, oral) alone was administered in group-V. After the study period, the rats were evaluated for liver enzyme markers, antioxidant parameters, histopathological changes, and cytokines levels. The hepatic proinflammatory mediator cytokines like TNF-α, IL-6, and IL-1β were evaluated through ELISA. The protein expression of Caspase-3, COX-2, and NF-κB were analysed through Western blotting techniques. Aqueous leaves extract of M. longifolia was able to normalize the changes caused by diclofenac. Current study indicatesthe protective effect of the aqueous leaves extract of M. longifolia against diclofenac-induced toxicity.
