Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage. Dextran sodium sulfate (DSS)-induced rat colitis models was used...

Inflammatory bowel disease (IBD) is associated with a number of immune-mediated extra-intestinal manifestations. Over half of all IBD patients have some form of respiratory pathology, most commonly neutrophil-mediated diseases such as bronchiectasis and chronic bronchitis. Using murine models of colitis, we aimed to identify the immune mechanisms driving pulmonary manifestations of IBD. We found increased neutrophil numbers in lung tissue associated with the pulmonary vasculature in both trinitrobenzenesulfonic acid- and dextran sulfate sodium-induced models of colitis...

End stage renal disease (ESRD) population account for 1.9 per patient year of hospital admissions annually. ESRD population are at increased risk of bleeding secondary to use of anticoagulation during hemodialysis and uremia induced platelet dysfunction. Gastrointestinal bleeding accounts for 3-7% of all deaths in ESRD population. Lower gastrointestinal bleeding refers to blood loss from a site in the gastrointestinal tract distal to the ligament of Treitz. It is usually suspected when a patient complains of hematochezia...

Nfκb2(p52/p100) plays essential roles in many chronic inflammatory diseases. Tracing the dynamic expression of Nfκb2 during different biological processes in vivo can provide valuable clues to understand the biological functions of this gene and develop anti-inflammatory drugs. In this study, B6-Tg(Nfκb2-luc)Mlit transgenic mouse line, a mouse model in which the expression of firefly luciferase gene is under the control of a 14.6-kb mouse Nfκb2 promoter, was generated to monitor the expression of p52/p100 in vivo...

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...

Chronic non-communicable diseases (NCDs) are low-level inflammation processes affected by several factors including diet. It has been reported that mixed whole grain and legume consumption, e.g. corn and common bean, might be a beneficial combination due to its content of bioactive compounds. A considerable amount would be retained in the non-digestible fraction (NDF), reaching the colon, where microbiota produce short-chain fatty acids (SCFAs) and phenolic compounds (PC) with known anti-inflammatory effect...

Chronic beryllium disease is a granulomatous lung disease, characterized by the accumulation of macrophages and beryllium-specific CD4+ T-cells that proliferate and produce T-helper cell type 1 cytokines. Previous studies indicate that beryllium-mediated oxidative stress enhances cytokine response in chronic beryllium disease CD4+ T-cells. 5-Aminosalicylic acid (5-ASA) is currently used to treat inflammatory bowel disease and has both antioxidant and antiinflammatory actions. We hypothesized that 5-ASA therapy may be a beneficial therapy in chronic beryllium disease...

Spondyloarthritis is a common type of arthritis which affects mostly adults. It consists of idiopathic chronic inflammation of the spine, joints, eyes, skin, gut, and prostate. Inflammation is often asymptomatic, especially in the gut and prostate. The HLA-B*27 allele group, which presents intracellular peptides to CD8+ T cells, is by far the strongest risk factor for spondyloarthritis. The precise mechanisms and antigens remain unknown. In 1959, Catterall and King advanced a novel hypothesis explaining the etiology of spondyloarthritis: an as-yet-unrecognized sexually acquired microbe would be causing all spondyloarthritis types, including acute anterior uveitis...

Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory condition that affects millions of people with high morbidity and health-care cost. The precise etiology of IBD is unknown, but clear evidence suggests that intestinal inflammation is caused by an excessive immune response to mucosal antigens. Recent studies have shown that activation of the aryl hydrocarbon receptor (AhR) induces regulatory T cells (Tregs) and suppresses autoimmune diseases. In the current study, we investigated if nontoxic ligand of AhR, 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE), can attenuate dextran sodium sulphate (DSS)-induced colitis...

Colorectal cancer is the most serious complication of chronic inflammatory bowel disease. It is generally accepted that dysplasia in most cases precedes the development of colorectal cancer. Thus, detection of dysplasia through surveillance may allow therapeutic interventions to lower the risk of cancer. Our understanding of dysplasia has evolved over the past decades and guided rational decision-making, but many questions remain unanswered. We are currently at the brink of a new era, where new avenues in the endoscopic detection and management of dysplasia are pursued, and the paradigm of a colectomy being the preferred treatment for advanced neoplasia is changing...

BACKGROUND: Previous data suggest that fecal S100A12 has clinical utility as a biomarker of chronic gastrointestinal inflammation (idiopathic inflammatory bowel disease) in both people and dogs, but the effect of gastrointestinal pathogens on fecal S100A12 concentrations is largely unknown. The role of S100A12 in parasite and viral infections is also difficult to study in traditional animal models due to the lack of S100A12 expression in rodents. Thus, the aim of this study was to evaluate fecal S100A12 concentrations in a cohort of puppies with intestinal parasites (Cystoisospora spp...

The yeast Saccharomyces cerevisiae and its components are used for the prevention and treatment of enteric disease in different species; therefore, they may also be useful for preventing Johne's disease, a chronic inflammatory bowel disease of ruminants caused by Mycobacterium avium ssp. paratuberculosis (MAP). The objective of this study was to identify potential immunomodulatory S. cerevisiae components using a bovine macrophage cell line (BOMAC). The BOMAC phagocytic activity, reactive oxygen species production, and immune-related gene (IL6, IL10, IL12p40, IL13, IL23), transforming growth factor β, ARG1, CASP1, and inducible nitric oxide synthase expression were investigated when BOMAC were cocultured with cell wall components from 4 different strains (A, B, C, and D) and 2 forms of dead yeast from strain A...
