Inflammatory bowel diseases are one of the important reasons of the referral to GI practitioners in our country and Ulcerative Colitis is the more frequent type of these disease in Iran. In this study 200 cases of Ulcerative Colitis, which has been referred to Imam Khomeini Hospital during that last 5 year, were studied. Data was collected using the patient's records and face to face interview ...
Background and purpose: Recent studies show that bronchial hyper-responsiveness occurs in a high proportion of inflammatory bowel disease. Âirway inflammation is a common pattern of respiratory involvement in ÏBD patients and is a major finding in bronchial asthma. This study was designed to evaluate the prevalence of asthma and air way hyper-responsiveness among ulcerative colitis patients. ...
T lymphocyte-expressing natural killer (NK) cell markers (NKT cells) play a role in immune regulation. Our aim was to evaluate the in vivo effect of adoptive transfer of immune-programmed NKT cells. Colitis was induced in C57/B6 mice by 2,4,6-trinitrobenzenesulfonic acid. NKT, CD4, CD8 lymphocytes, and dendritic cells (DC) were prepared from spleens of naive mice, animals with colitis, and anim...
BACKGROUND & AIMS Hydrogen sulfide (H(2)S) is an endogenous gaseous mediator of mucosal defense with antiinflammatory effects that promote ulcer healing. The effects of H(2)S during the pathogenesis of colitis have not been established. We analyzed the contribution of H(2)S to inflammation and ulceration of the colon in a rat model of colitis. METHODS Colitis was induced by intracolonic admin...
Faecal samples were collected from 23 patients with active ulcerative colitis, 15 patients with established ulcerative colitis in remission, 20 patients with active colitis of cause other than ulcerative colitis, and 20 normal control subjects. Ten coliform colonies were randomly selected from the faecal sample cultures and serotyped before the testing of each different serotype from each sampl...
The relation between inflammatory bowel disease (IBD), mainly ulcerative colitis, and primary sclerosing cholangitis (PSC) is particularly close, as approximately two thirds of patients with PSC have, or will develop, ulcerative colitis, and PSC occurs in approximately 3–7% of patients with ulcerative colitis. In a large Swedish epidemiological study, approximately 5.5% of patients with extensi...
Immunohistological techniques using monoclonal antibodies were employed to study the morphology and phenotypic expression of macrophage like cells in ulcerative colitis, Crohn's colitis and histologically normal colonic mucosa. The antibody RFD1 identifies interdigitating (antigen presenting) cells whereas RFD7 binds to mature tissue macrophages. In normal colonic mucosa, the majority of cells ...
Microscopic colitis is a common cause of chronic diarrhea. Over the last years the incidence and the prevalence of microscopic colitis are rising and this rise is largely attributed to a rising awareness, and concomitantly an increasing number of diagnoses are made. Patients with microscopic colitis report watery, nonbloody diarrhea of chronic, intermittent, or chronic recurrent course. Followi...
The prevalence of ulcerative colitis, one the inflammatory bowel diseases, has been increasing worldwide. Though fatty diet leads to development only little is known about separate and combined effects different fat compositions intermittent fasting, preventative dietary changes on experimental colitis. In this study, we investigated effect feeding type frequency inflammation Five groups, each ...
The intestinal mucosal barrier controlling the resident microbiome is dependent on a protective mucus layer generated by goblet cells, impairment of which is a hallmark of the inflammatory bowel disease, ulcerative colitis. Here, we show that IL-18 is critical in driving the pathologic breakdown of barrier integrity in a model of colitis. Deletion of Il18 or its receptor Il18r1 in intestinal ep...
