Mpakogiannis K, Fousekis FS, Katsanos AH, Katsanos KH. Can Hypnotherapy Be Considered a Valuable Component in the Management of Inflammatory Bowel Disease? Insights from a Comprehensive Review. Int J Clin Exp Hypn 2024:1-15. [PMID: 38743845 DOI: 10.1080/00207144.2024.2350460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 04/26/2024] [Indexed: 05/16/2024]
Abstract
Despite advancements in medication,managing inflammatory bowel disease (IBD) remains challenging, necessitatingalternative control methods. Gut-directed hypnotherapy, known for alleviating irritable bowel syndrome (IBS), is debated as an IBD management method. Anextensive search across PubMed, Cochrane Library, and Clinicaltrials.govuncovered five randomized trials and two case series involving IBD patients undergoing hypnotherapy. A small trial reported statistically significant remission at one year (p = .04), but larger trials, including one with 63 patients, showed no significant gastrointestinal improvements. The first case series noted post-intervention reduction in the mediators of inflammation in rectal mucosal, without long-term monitoring. The second case series observed the absence of flare episodes in 12 of 13 ulcerative colitis patients during follow-up, possibly influenced by the simultaneous use of two drugs alongside hypnotherapy. Psychological outcomes, demonstrated no significant differences between hypnotherapy and control groups. While current literature doesn't decisively support hypnotherapy for managing IBD symptoms, it underscores the importance of further research, including randomized clinical trials, to thoroughly assess its effectiveness in this context.

Abstract
Inflammatory bowel disease (IBD) is an inflammatory disorder that affects the gastrointestinal tract. IBD has become an increasingly common condition in both developed and developing nations over the last few decades, owing to a variety of factors like a rising population and diets packed with processed and junk foods. While the root pathophysiology of IBD is unknown, treatments are focused on medications aimed to mitigate symptoms. Alginate (AG), a marine-derived polysaccharide, is extensively studied for its biocompatibility, pH sensitivity, and crosslinking nature. This polymer is thoroughly researched in drug delivery systems for IBD treatment, as it is naturally available, non-toxic, cost effective, and can be easily and safely cross-linked with other polymers to form an interconnected network, which helps in controlling the release of drugs over an extended period. There are various types of drug delivery systems developed from AG to deliver therapeutic agents; among them, nanotechnology-based systems and hydrogels are popular due to their ability to facilitate targeted drug delivery, reduce dosage, and increase the therapeutic efficiency. AG-based carrier systems are not only used for the sustained release of drug, but also used in the delivery of siRNA, interleukins, and stem cells for site directed drug delivery and tissue regenerating ability respectively. This review is focussed on pathogenesis and currently studied medications for IBD, AG-based drug delivery systems and their properties for the alleviation of IBD. Moreover, future challenges are also be discoursed to improve the research of AG in the field of biopharmaceuticals and drug delivery.

Abstract
Ulcerative colitis (UC) is a chronic disease that is characterized by diffuse inflammation of the colonic and rectal mucosa. The burden of UC is rising globally with significant disparities in levels and trends of disease in different countries. The pathogenesis of UC involves the presence of pathogenic factors including genetic, environmental, autoimmune, and immune-mediated components. Evidence suggests that disturbed interactions between the host immune system and gut microbiome contribute to the origin and development of UC. Current medications for UC include antibiotics, corticosteroids, and biological drugs, which can have deleterious off-target effects on the gut microbiome, contributing to increased susceptibility to severe infections and chronic immunosuppression. Alternative, nonpharmacological, and behavioral interventions have been proposed as safe and effective treatments to alleviate UC, while also holding the potential to improve overall life quality. This mini-review will discuss the interactions between the immune system and the gut microbiome in the case of UC. In addition, we suggest nonpharmacological and behavioral strategies aimed at restoring a proper microbial-immune relationship.

Abstract
Crohn's disease (CD) is a chronic inflammatory gastrointestinal disorder requiring lifelong medications. The currently approved drugs for CD are associated with relevant side effects and several studies suggest an increased use of nutraceuticals among CD patients, seeking for what is perceived as a more "natural" approach in controlling this highly morbid condition. Nutraceuticals are foods or foods' components with beneficial health properties that could aid in CD treatment for their anti-inflammatory, analgesic and immunoregulatory activities that come along with safety, high tolerability, easy availability and affordability. Depending on their biological effect, nutraceuticals' support could be employed in different subsets of CD patients, both those with active disease, as adjunctive immunomodulatory therapies, and/or in quiescent disease to provide symptomatic relief in patients with residual functional symptoms. Despite the increasing interest of the general public, both limited research and lack of education from healthcare professionals regarding their real clinical effectiveness account for the increasing number of patients turning to unconventional sources. Professionals should recognize their widespread use and the evidence base for or against their efficacy to properly counsel IBD patients. Overall, nutraceuticals appear to be safe complements to conventional therapies; nonetheless, little quality evidence supports a positive impact on underlying inflammatory activity.

Abstract
The onset of inflammatory bowel disease (IBD) involves many factors, including environmental parameters, microorganisms, and the immune system. Although research on IBD continues to expand, the specific pathogenesis mechanism is still unclear. Protein modification refers to chemical modification after protein biosynthesis, also known as post-translational modification (PTM), which causes changes in the properties and functions of proteins. Since proteins can be modified in different ways, such as acetylation, methylation, and phosphorylation, the functions of proteins in different modified states will also be different. Transitions between different states of protein or changes in modification sites can regulate protein properties and functions. Such modifications like neddylation, sumoylation, glycosylation, and acetylation can activate or inhibit various signaling pathways (e.g., nuclear factor-κB (NF-κB), extracellular signal-regulated kinase (ERK), and protein kinase B (AKT)) by changing the intestinal flora, regulating immune cells, modulating the release of cytokines such as interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ), and ultimately leading to the maintenance of the stability of the intestinal epithelial barrier. In this review, we focus on the current understanding of PTM and describe its regulatory role in the pathogenesis of IBD.

Abstract
Inflammatory bowel disease (IBD) is a term that encompasses conditions characterized by chronic inflammation of the gastrointestinal tract (GIT). It includes Crohn's disease and ulcerative colitis. Major scientific organizations interested in gastrointestinal systems or GIT-focused organizations worldwide release guidelines for diagnosing, classifying, managing, and treating IBD. However, there are subtle differences among each of these guidelines. This review evaluates four evidence-based guidelines in the management of IBD and seeks to highlight the differences and similarities between them. The main differences in the evaluated guidelines were in diagnosis and treatment recommendations. The diagnosing recommendations were comparable amongst the four guidelines; however, some were more specific about limiting the number of interventions necessary to confirm a diagnosis. Regarding treatment options, each guideline had clear suggestions about what was considered ideal. Although the treatment options were identical, the main differences existed in the recommended diets and initial therapy in patients with moderate disease. Clinical practice guidelines (CPGs) recommend evidence-based practice from opinion leaders in clinical decision-making. Rather than dictating a one-size-fits-all approach in IBD management, reviewing various guidelines can enhance the cross-pollination of ideas amongst clinicians to improve decision-making. Clearly describing and appraising evidence-based reasoning for scientific recommendations remain driving factors for quality patient care. The effectiveness of CPGs in improving health and the complexities of their formation requires constant review to maximize constructive criticisms and explore possible improvements.

Abstract
Traditional ayurvedic medicine, Arjunarishta (AA) is used to treat several inflammatory conditions including dysentery associated with blood. The formulation is a decoction of Terminalia arjuna (Roxb.) Wight and Arn. (TA), Madhuca indica J.F.Gmel., Vitis vinifera L., Woodfordia fruticosa (L.) Kurz., and Saccharum officinarum L. Terminalia arjuna, a major constituent of this formulation has been recognized for anti-inflammatory effects. This study aimed at evaluating beneficial effects of AA and probable mechanism of action in Trinitrobenzenesulphonicacid (TNBS) induced colitis model. Response to AA treatment was explored through determination of disease activity index (DAI), histological assessment and damage scores, colonic pro-inflammatory cytokine/chemokine expression and estimation of oxidative stress biomarkers. Improvement in gut microbiome and plasma zinc level was also assessed. Study findings directed therapeutic effects of AA treatment in colitis model by attenuating the colitis symptoms such as weight loss, diarrhoea, blood in stool; histological damage; and downregulated expression of pro-inflammatory cytokines/chemokine (TNF-α, IL-1β, IL-6) and MCP-1). Similarly reduced oxidative stress by decreased level of Nitric Oxide (NO), Myeloperoxidase (MPO), Malondialdehyde (MDA) and enhanced level of Catalase (CAT), Superoxide dismutase (SOD) and Reduced Glutathione (GSH) was also witnessed. In addition, an improved beneficial fecal microbiome profile and restored plasma zinc status was revealed compared to the TNBS control group. The present study directs that downregulated pro-inflammatory cytokines/chemokine expression, enhancement of antioxidant effect, increased plasma zinc status and promising role in modulating fecal microbiome might be potential mechanisms for the therapeutic effect of AA treatment against colitis.

Abstract
Glioma, especially its most malignant type, Glioblastoma (GBM), is the most common and the most aggressive malignant tumour in the central nervous system. Currently, we have no specific therapies that can significantly improve its dismal prognosis. Recent studies have reported promising in vitro experimental results of several novel glioma-targeting drugs; these studies are encouraging to both researchers and patients. However, clinical trials have revealed that novel compounds that focus on a single, clear glioma genetic alteration may not achieve a satisfactory outcome or have side effects that are unbearable. Based on this consensus, phytochemicals that exhibit multiple bioactivities have recently attracted much attention. Traditional Chinese medicine and traditional Indian medicine (Ayurveda) have shown that phytocompounds inhibit glioma angiogenesis, cancer stem cells and tumour proliferation; these results suggest a novel drug therapeutic strategy. However, single phytocompounds or their direct usage may not reverse comprehensive malignancy due to poor histological penetrability or relatively unsatisfactory in vivo efficiency. Recent research that has employed temozolomide combination treatment and Nanoparticles (NPs) with phytocompounds has revealed a powerful dual-target therapy and a high blood-brain barrier penetrability, which is accompanied by low side effects and strong specific targeting. This review is focused on major phytocompounds that have contributed to glioma-targeting treatment in recent years and their role in drug resistance inhibition, as well as novel drug delivery systems for clinical strategies. Lastly, we summarize a possible research strategy for the future.

Clematichinenoside AR ameliorated spontaneous colitis in Il-10 -/- mice associated with improving the intestinal barrier function and abnormal immune responses. Life Sci 2019; 239:117021.

Abstract
OBJECTIVES Clematichinenoside AR (AR) is a saponin extracted for traditional Chinese medicine with the effects of improving the expression of tight junction (TJ) proteins and mediating anti-inflammatory activities. However, its effect on Crohn's disease (CD) is still unknown. We aimed to investigate the impact of AR on CD-like colitis and determine the mechanism underlying its effects. METHODS Interleukin-10 gene knockout (Il-10-/-) mice (male, fifteen weeks old) with spontaneous colitis were allocated to the positive control and AR-treated (32 mg/kg AR administered every other day by gavage for 4 weeks) groups. Wild-type (WT) mice (male, fifteen weeks old) composed the negative control group. The effects of AR on intestinal barrier function and structure and T cell responses as well as the potential mechanisms underlying these effects were investigated. RESULTS AR treatment significantly improved spontaneous colitis in Il-10-/- mice as demonstrated by reductions in the inflammatory score, disease activity index (DAI) and levels of inflammatory factors. The effects of AR on colitis in Il-10-/- mice were related to protecting intestinal barrier function and maintaining immune system homeostasis (regulatory T cell (Treg)/T helper 17 (Th17) cell balance). The anticolitis effect of AR may partly act by downregulating PI3K/Akt signaling. CONCLUSIONS AR may have therapeutic potential for treating CD in humans.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna Roxb. (Combretaceae) is traditionally used in Ayurveda medicine and holds ethnomedicinal importance for treatment of gastrointestinal disorders. In view of its anti-inflammatory, antidiarrheal and antioxidant potential, it could be beneficial for the treatment of inflammatory bowel disease (IBD), which is associated with interaction between genetic, environmental factors and intestinal microbiome leading to dysregulated immune responses. This study evaluates the effect of hydroalcoholic extract of Terminalia arjuna bark (TAHA) in trinitrobenzenesulfonic acid (TNBS) model of rat colitis which resembles human IBD. MATERIALS AND METHODS TAHA (500, 250, 125 mg/kg) was administered orally for 28 days in TNBS induced rats. Response to treatment was assessed by comparing observations in diseased and treated groups using disease activity index (DAI); macroscopic/histological damage; determining oxidative stress indicators: myeloperoxidase, malondialdehyde, nitric oxide, catalase, superoxide dismutase, and reduced glutathione; gene expression of pro-inflammatory cytokines such as IL-6, IL-1β, TNF-α and chemokine: MCP-1. Furthermore, the role of TAHA in altering the gut microbiota profile in rat feces and plasma zinc was also studied. RESULTS TAHA treatment in colitic rats directed decreased DAI scores, macroscopic and histologic damage. It also reduced myeloperoxidase, malondialdehyde and nitric oxide level. Whereas, prevented depletion of plasma catalase, superoxide dismutase and glutathione level. In addition, TAHA treatment down-regulated the gene expression of pro-inflammatory mediators and displayed altered beneficial effect on fecal microbiota. Furthermore, enhanced plasma zinc level supported the beneficial effect of TAHA in colitic rats. The dose of TAHA that produced most significant beneficial effect was 500 mg/kg. CONCLUSION TAHA administration relieved the disease activity in TNBS induced colitis by reducing expression of pro-inflammatory cytokines and chemokine, decreasing oxidative stress, and improving plasma zinc level and structure of gut microbiota.

Abstract
Ulcerative colitis (UC) is a chronic, relapsing, remitting, and inflammatory disorder that afflicts millions of people around the world. It carries a substantial economic burden, reducing the quality of life, ability to work, and increasing disability. Conventional medical treatment of UC includes the use of aminosalicylates, corticosteroids, and immunosuppressive drugs. However, these medicines are not always effective due to some serious side effects. Nuclear factor-kappa B (NF-κB) is a key factor in the inflammatory setting and strongly affects the course of mucosal inflammation in UC. This review aims to describe the complex role of NF-κB in UC and discuss existing pharmacological attempts by curcumin for blocking NF-κB activation to develop new therapeutic strategies in UC. Several studies have shown intriguing pharmacologic effects associated with curcumin, which inhibits NF-κB expression by regulating NF-κB/IkB pathway and down-regulation expression of pro-inflammatory cytokines, such as Interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor (TNF)-α. The efficacy of curcumin has been confirmed in several experimental models of UC. Furthermore, curcumin significantly induced clinical remission in active mild-to-moderate UC patients and reduced clinical relapse in quiescent UC patients. The inhibitory effects of curcumin on NF-κB and its unrivaled safety profile indicate that it remains effective for the treatment of UC. In addition, curcumin is a nontoxic, inexpensive, and easily available natural polyphenol. In conclusion, curcumin can be used as a potential and safe drug in the management of patients with remission and mild-to-moderate UC.

Abstract
Inflammatory Bowel Disease (IBD) is characterized by chronic inflammation of all or part of the digestive tract. Nutraceuticals include bioactive compounds such as polyphenols with anti-inflammatory activities, thus these products have the potential to treat chronic inflammatory diseases. We have emphasized the role of nutraceuticals in ameliorating the symptoms of IBD in rodent models of human IBD through modulation of key pathogenic mechanisms including dysbiosis, oxidative stress, increased inflammatory cytokines, immune system dysregulation, and inflammatory cell signaling pathways. Nutraceuticals have an important role in IBD patients as a preventive approach to extend remission phases and as a therapeutic intervention to suppress active IBD. Further clinical trials on nutraceuticals with positive results in rodent models are warranted.

Abstract
The complement-activated product, complement component 5a (C5a), is a potent inflammatory peptide with a broad spectrum of functions. In vivo and in vitro studies have demonstrated that C5a serves an important role in inflammation; however, the role of C5a in the pathogenesis of inflammatory bowel disease (IBD) is not known. The purpose of the current study was to investigate the role of C5a in IBD using an experimental mouse model of colitis. Colitis was induced in mice using 2,4,6-trinitrobenzene sulfonic acid (TNBS), and C5a aptamers were subsequently administered via intraperitoneal injection. Clinical symptoms of the disease, histopathological analysis of the colon and the level of inflammatory components were examined. The symptoms of colitis, including changes in behavior, weight loss, colon damage and an increase in inflammatory cytokines, were attenuated following the treatment of mice with TNBS-induced colitis with C5a aptamers. The aptamer-treated mice exhibited a marked attenuation of colitis when compared with untreated mice, as demonstrated by the phenotypic observations, histological examinations and inflammatory cytokine levels. Colitis is characterized by an imbalance between pro-inflammatory and anti-inflammatory mediators. The results of the current study suggest that C5a may serve a critical role in inflammation in IBD.

Abstract
Autoimmune diseases are still considered to be pressing concerns due the fact that they are leaders in death and disability causes worldwide. Resveratrol is a polyphenol derived from a variety of foods and beverages, including red grapes and red wine. Anti-inflammatory, antioxidant, and antiaging properties of resveratrol have been reported, and in some animal and human studies this compound reduced and ameliorated the progression of autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, psoriasis, inflammatory bowel disease, and type 1 diabetes mellitus. Thus, this review aims to summarize and critically analyze the role of resveratrol in the modulation of several organ-specific or systemic autoimmune diseases.

Abstract
ETHNOPHARMOCOLOGICAL RELEVANCE Terminalia catappa Linn (Combretaceae) is a medicinal plant with anti-inflammatory, anti-diarrhoeal and antioxidant properties, frequently found in tropical regions. Considering its characteristics, it could be useful for the treatment of inflammatory bowel disease, which is associated with inflammation, oxidative stress and an immune dysfunction. Thus this study evaluates the immunomodulatory properties and the intestinal anti-inflammatory effect of an ethanolic extract of the stem bark of T. catappa (ETCB) both in vitro (in RAW 264.7 macrophages) and in vivo, in the trinitrobenzenesulfonic acid (TNBS) model of rat colitis. MATERIALS AND METHODS The phenolic compounds in ETCB were identified and quantified using HPLC-DAD-qTOF-MS. The immunomodulatory activity ETCB was tested in vitro by determining the macrophage production of IL-1β and nitrites. In vivo studies were performed in the TNBS model of rat colitis. ETCB was given (25, 50 and 100mg/kg/day) orally for two days prior to colitis induction and thereafter for 7 days. Response to treatment was assessed by scoring the gross appearance of the colon, and determining myeloperoxidase activity, gene expression of pro-inflammatory cytokines like TNF-α, IL-23 and IL-6, chemokines, inducible nitric oxide synthase and proteins crucial in the maintenance of the intestinal mucosal barrier integrity like mucins (MUC-2, MUC-3) and villin. RESULTS ETCB was able to inhibit IL-1β and nitrite production in vitro in RAW 264.7 macrophages. Moreover, treatment of TNBS colitic rats with ETCB resulted in a decreased colonic damage score and weight/length ratio. It also reduced the colonic neutrophil infiltration indicated by a lower myeloperoxidase activity and prevented the depletion of colonic glutathione levels in colitic rats. In addition, treatment with ETCB down-regulated the gene expression of pro-inflammatory mediators (TNF-α, IL-23, IL-6 and CINC-1) and iNOS in colitic rats. Moreover, the gene expression of mucosal barrier proteins like MUC-2, MUC-3 and villin were up-regulated in colitic rats treated with ETCB. The dose of ETCB that produced the most significant beneficial effect was 100mg/kg. Regarding the chemical composition of ETCB, 31 phenolic compounds were identified, including ellagic acid, catalagin and gallic acid. CONCLUSION The beneficial effect of ETCB in the TNBS induced colitis in rats could be related to its antioxidant, immunomodulatory and anti-inflammatory activities, which could be attributed to the phenolic compounds identified.

Abstract
BACKGROUND AND AIMS Ulcerative colitis (UC) is a chronic idiopathic inflammatory disease in which reducing pro-inflammatory and/or increasing anti-inflammatory molecules is the mainstay of treatment. The aim of this study was to evaluate the effects of supplementation with resveratrol as an antiinflammatory and antioxidant agent on inflammation and quality of life in patients with active UC. METHODS AND RESULTS In this randomized, double-blind, placebo-controlled study, 50 eligible patients with active mild to moderate UC were supplemented with either a 500-mg resveratrol or placebo capsule for 6 weeks. Serum inflammatory markers, activity of NF-κB in peripheral blood mononuclear cells (PBMC) and quality of life were assessed at baseline and at the end of the study. Resveratrol supplementation led to a significant reduction in plasma levels of TNF-α (19.70 ± 12.80 to 17.20 ± 10.09 pg/mL) and hs-CRP (4764.25 ± 2260.48 to 2584.50 ± 1792.80 ng/mL) and activity of NF-κB in PBMCs (0.19 ± 0.05 to 0.10 ± 0.04 OD) (p <0.001), whereas there were no significant changes of these factors in placebo group. Also, the score of inflammatory bowel disease questionnaire -9 (IBDQ-9) increased, whereas the clinical colitis activity index score decreased significantly in the resveratrol group (32.72 ± 7.52 to 47.64 ± 8.59) (p <0.001) and when compared with the placebo group (35.54 ± 9.50 to 41.08 ± 6.59) (p <0.001). CONCLUSION Our results indicate that 6 weeks supplementation with 500 mg resveratrol can improve quality of life and disease clinical colitis activity at least partially through inflammation reduction in patients with UC. Whether these effects will be continued in longer duration of treatment remains to be determined.

Abstract
The upregulation of heme oxygenase-1 (HO-1) has proven to be a useful tool for fighting inflammation. In order to identify new HO-1 inducers, an efficient screening method was developed which can provide new lead structures for drug research. We designed a simple ELISA-based HO-1 enzyme activity assay, which allows for the screening of 12 compounds in parallel in the setting of a 96-well plate. The well-established murine macrophage cell line RAW264.7 is used and only about 26µg of protein from whole cell lysates is needed for the analysis of HO-1 activity. The quantification of HO-1 activity is based on an indirect ELISA using the specific anti-bilirubin antibody 24G7 to quantify directly bilirubin in the whole cell lysate, applying a horseradish peroxidase-tagged antibody together with ortho-phenylenediamine and H2O2 for detection. The bilirubin is produced on the action of HO enzymes by converting their substrate heme to biliverdin and additional recombinant biliverdin reductase together with NADPH at pH 7.4 in buffer. This sensitive assay allows for the detection of 0.57-82pmol bilirubin per sample in whole cell lysates. Twenty-three small molecules, mainly natural products with an α,β-unsaturated carbonyl unit such as polyphenols, including flavonoids and chalcones, terpenes, an isothiocyanate, and the drug oltipraz were tested at typically 6 or 24h incubation with RAW264.7 cells. The activity of known HO-1 inducers was confirmed, while the chalcones cardamonin, flavokawain A, calythropsin, 2',3,4'-trihydroxy-4-methoxychalcone (THMC), and 2',4'-dihydroxy-3,4-dimethoxychalcone (DHDMC) were identified as new potent HO-1 inducers. The highest inductive power after 6h incubation was found at 10µM for DHDMC (6.1-fold), carnosol (3.9-fold), butein (3.1-fold), THMC (2.9-fold), and zerumbone (2.5-fold). Moreover, the time dependence of HO-1 protein production for DHDMC was compared to its enzyme activity, which was further evaluated in the presence of lipopolysaccharide and the specific HO-1 inhibitor tin protoporphyrin IX. Taken together, we developed a convenient and highly sensitive ELISA-based HO-1 enzyme activity assay, allowing the identification and characterization of molecules potentially useful for the treatment of inflammatory and autoimmune diseases.

Abstract
INTRODUCTION Nowadays, there is an increasing interest for alternative options in the treatment of inflammatory bowel diseases (IBDs) that combine efficacy and an adequate safety profile. METHODS The intestinal anti-inflammatory effects of Serpylli herba, the officinal drug in the European Pharmacopeia composed by the aerial parts of wild thyme (Thymus serpyllum), were evaluated in the trinitrobenzenesulfonic acid (TNBS)-induced rat colitis and dextran sodium sulfate (DSS)-induced mouse colitis, which are well characterized experimental models with some resemblance to human IBD. RESULTS S. herba extract exerted an intestinal anti-inflammatory effect in both experimental models of colitis, as evidenced both histologically, since it facilitated the tissue recovery of the damaged colon, and biochemically as showed by the improvement of the different inflammatory markers evaluated, including myeloperoxidase activity, glutathione content, and leukotriene B4 levels as well as the expression of the inducible proteins iNOS and COX-2. This beneficial effect was associated with the reduction in the expression of different cytokines, like TNFα, IL-1β, IFNγ, IL-6 and IL-17, the chemokine MCP-1, and the adhesion molecule ICAM-1, thus ameliorating the altered immune response associated with the colonic inflammation. CONCLUSION S. herba extract displays an anti-inflammatory effect on different models of rodent colitis that could be attributed to its immunomodulatory properties.

Abstract
The pleiotropic effects of resveratrol include anti-inflammatory, antioxidant, and anticancer activities, and thus unique possibilities exist to explore mechanistic pathways of chemoprevention. The aim of this study was to investigate the role of microRNA (miRNA) alterations induced by resveratrol in the context of chemopreventive mechanisms against dextran sodium sulfate (DSS)-induced colitis-associated tumorigenesis in the Apc(Min/+) mouse. To that end, Apc(Min/+) mice were exposed to 2% DSS to enhance intestinal inflammation and polyp development. Concurrently, mice received either vehicle or resveratrol treatment via oral gavage for 5 weeks. Interestingly, treatment of DSS-exposed mice with resveratrol resulted in decreased number and size of polyps, fewer histologic signs of cell damage, and decreased proliferating epithelial cells in intestinal mucosa compared with vehicle. Resveratrol treatment dramatically reversed the effects of DSS on the numbers of specific inflammatory CD4(+) T cells, CD8(+) T cells, B cells, natural killer T cells, and myeloid-derived suppressor cells in mesenteric lymph nodes. Resveratrol treatment also decreased interleukin-6 (IL-6) and tumor necrosis factor-α protein levels and reduced IL-6 and cyclooxygenase-2 mRNA expression. Microarray analysis revealed 104 miRNAs exhibiting >1.5-fold differences in expression in the intestinal tissue of resveratrol-treated mice. Among them, two miRNAs with anti-inflammatory properties, miRNA-101b and miRNA-455, were validated to be upregulated with resveratrol treatment by reverse-transcription polymerase chain reaction. Pathway analysis revealed that numerous differentially regulated miRNAs targeted mRNAs associated with inflammatory processes with known roles in intestinal tumorigenesis. These results suggest that resveratrol mediates anti-inflammatory properties and suppresses intestinal tumorigenesis through miRNA modulation.

Cooked navy and black bean diets improve biomarkers of colon health and reduce inflammation during colitis. Br J Nutr 2014; 111:1549-63.

Abstract
Common beans contain non-digestible fermentable components (SCFA precursors) and phenolic compounds (phenolic acids, flavonoids and anthocyanins) with demonstrated antioxidant and anti-inflammatory potential. The objective of the present study was to assess the in vivo effect of cooked whole-bean flours, with differing phenolic compound levels and profiles, in a mouse model of acute colitis. C57BL/6 mice were fed a 20 % navy bean or black bean flour-containing diet or an isoenergetic basal diet (BD) for 2 weeks before the induction of experimental colitis via 7 d dextran sodium sulphate (DSS, 2 % (w/v) in the drinking-water) exposure. Compared with the BD, both bean diets increased caecal SCFA and faecal phenolic compound concentrations (P< 0·05), which coincided with both beneficial and adverse effects on colonic and systemic inflammation. On the one hand, bean diets reduced mRNA expression of colonic inflammatory cytokines (IL-6, IL-9, IFN-γ and IL-17A) and increased anti-inflammatory IL-10 (P< 0·05), while systemically reduced circulating cytokines (IL-1β, TNFα, IFNγ, and IL-17A, P< 0·05) and DSS-induced oxidative stress. On the other hand, bean diets enhanced DSS-induced colonic damage as indicated by an increased histological injury score and apoptosis (cleaved caspase-3 and FasL mRNA expression) (P< 0·05). In conclusion, bean-containing diets exerted both beneficial and adverse effects during experimental colitis by reducing inflammatory biomarkers both locally and systemically while aggravating colonic mucosal damage. Further research is required to understand the mechanisms through which beans exert their effects on colonic inflammation and the impact on colitis severity in human subjects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Different species from genus Phlomis, frequently native from the the eastern Mediterranean zone, have been used in traditional medicine as an anti-inflammatory remedy. Among other constituents, they contain polyphenols that show antioxidant properties, which are interesting for the treatment of inflammatory pathologies associated with oxidative stress in humans, such as inflammatory bowel disease (IBD). The aim of this study was to evaluate the intestinal anti-inflammatoy effect of hydroalcoholic extracts of Phlomis lychnitis and P. purpurea in the trinitrobenzenesulphonic acid (TNBS) model of rat colitis, a well characterized experimental model with some resemblance to human IBD. MATERIALS AND METHODS Hydroalcoholic extracts of both plants were characterized by determining their polyphenolic content and then assayed in the TNBS model of rat colitis. For this purpose, female Wistar rats were assigned to seven groups (n=10): healthy control, untreated TNBS-colitis and five TNBS- colitis groups treated with Phlomis lychnitis (10 and 20mg/kg), P. purpurea (10 and 25mg/kg) and sulphasalazine (200mg/kg), as a positive control. Treatments started the same day of TNBS colitis induction, and rats were sacrificed one week later. Colonic inflammation was evaluated both histologically and biochemically. RESULTS The histological (macroscopic and microscopic) analysis of colonic samples revealed that both extracts showed an anti-inflammatory effect, which was confirmed biochemically by a decreased colonic MPO activity, a maker of neutrophil infiltration, an increased colonic glutathione content, which counteracts the oxidative status associated with the inflammatory process, and a down-regulated iNOS expression. However, only the extract of P. purpurea reduced the expression of the proinflammatory cytokines IL-1β and IL-17, the chemokines CINC-1 and MCP-1, as well as the adhesion molecule ICAM-1, ameliorating the altered immune response associated with the colonic inflammation. Furthermore, both P. lychnitis and P. purpurea extracts were able to significantly increase the expression of markers of epithelial integrity such as MUC-2, MUC-3 and villin, thus revealing an improvement in the altered colonic permeability that characterizes colonic inflammation. CONCLUSIONS Both extracts showed intestinal anti-inflammatory activity in the TNBS model of rat colitis, thus confirming their traditional use in digestive inflammatory complaints. In addition to their antioxidant properties, other mechanisms can contribute to this beneficial effect, like an improvement in the intestine epithelial barrier and a downregulation of the immune response.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Brazilian traditional medicine, Arctium lappa (Asteraceae), has been reported to relieve gastrointestinal symptoms. AIM OF THE STUDY In the present study, we investigated the effects of the lactone sesquiterpene onopordopicrin enriched fraction (ONP fraction) from Arctium lappa in an experimental colitis model induced by 2,4,6 trinitrobenzene sulfonic acid and performed experiments to elucidate the underlying action mechanisms involved in that effect. MATERIALS AND METHODS ONP fraction (25 and 50 mg/kg/day) was orally administered 48, 24 and 1 h prior to the induction of colitis and 24 h after. The inflammatory response was assessed by gross appearance, myeloperoxidase (MPO) activity, tumor necrosis factor alpha (TNF-α) levels and a histological study of the lesions. We determined cyclooxygenase (COX)-1 and -2 protein expressions by western blotting and immunohistochemistry assays. RESULTS TNBS group was characterized by increased colonic wall thickness, edema, diffuse inflammatory cell infiltration, increased MPO activity and TNF-α levels. On the contrary, ONP fraction (25 and 50 mg/kg) treatment significantly reduced the macroscopic inflammation scores (p<0.05 and p<0.01, respectively) and morphological alterations associated with an increase in the mucus secretion. Similarly, the degree of neutrophil infiltration and the cytokine levels were significantly ameliorated. Moreover, COX-2 expression was up regulated in TNBS-treated rats. In contrast, ONP fraction (50 mg/kg) administration reduced COX-2 overexpression. CONCLUSIONS We have shown that the ONP fraction obtained from Arctium lappa exert marked protective effects in acute experimental colitis, confirming and justifying, at least in part, the popular use of this plant to treat gastrointestinal diseases.

Abstract
Ulcerative colitis (UC) is an inflammation-associated disease of the colon and rectum. The onset and progress of the disease are directly influenced by the nature of the intestinal microflora, the intestinal barrier function, and the immunological responses of the host. The epithelial invasion of pathogenic bacteria due to excess contact and/or barrier dysfunction is related to inflammation mediated by intestinal immune responses. Although the etiology of UC is not clearly understood, recent studies have shown a rising incidence of UC worldwide, and this phenomenon is more prominent in Asian countries and in Asian immigrants in Western countries. The increased prevalence of UC also contributes to an increased risk of developing colorectal cancer. Environmental factors, including changes in dietary habits, have been suggested as major risk factors of UC. A systematic review showed a negative association between UC risk and vegetable intake, whereas total fat, omega-6 fatty acids and meat intake were positively associated with an increased risk of UC. Individual dietary factors and energy balance have been suggested as having important roles in inducing changes in the microbial population and intestinal barrier integrity and in regulating inflammatory immune responses, directly or indirectly. Excess energy intake is now known to increase pathogenic microbial populations. Likewise, the application of appropriate probiotics may reverse the pathogenic progression of the disease. In the meantime, dietary anti-inflammatory compounds, including omega-3 fatty acids and other phytochemicals, may directly suppress inflammatory responses in the course of UC development. In this review, the increased prevalence of UC and its management are interpreted from the standpoint of nutritional modulation to regulate the intestinal microflora population, intestinal epithelium permeability, and inflammatory responses.
