background: colorectal cancer is a common and lethal disease with various distribution of incidence in different part of the world and it is known as the third most common cause of cancer death in the world. since several studies in the world represented different survival rates for colorectal cancer in this study we aimed to determine the survival of a group of iranian patients and some relate...

BACKGROUND Several papers have indicated that glutamine is a preferred fuel for the enterocyte and that it can increase intestinal epithelial cell proliferation. AIMS To investigate the effects of glutamine on intestinal epithelial cell proliferation in the parenterally fed rat. METHODS Five groups of six rats were fed parenterally; a group of orally fed rats was also studied. Crypt cell pr...

Because of the difficulty often encountered in deciding whether a patient's symptoms originate in the upper or lower gastrointestinal tract, gastrointestinal transit scintigraphy is a uniquely suited noninvasive, quantitative, and physiologic method of determining whether there is a motility disorder affecting the stomach, small bowel, or colon. Small-bowel and colon transit studies can be perf...

In a large retrospective survey of colics from 14 Universities in the USA and from 2 in the United Kingdom from 1979 to 1984, case fatality rate was 68.2% for the small intestine, compared with 40.7% for the large colon, regardless of treatment. In a more recent study (1987-1991), the survival rate for surgery on the cecum and colon (80%) was significantly higher than survival (52%) for horses ...

The effects of chronic inhibition of ornithine decarboxylase (ODC) by the specific inhibitor difluoromethylornithine (DFMO) in the rat colon and small intestine on mucosal contents of polyamines, decarboxylated S-adenosylmethionine (decarboxylated AdoMet) and S-adenosylmethionine decarboxylase (AdoMet decarboxylase) activity were studied. Administration of 1% DFMO in the drinking water for 10 o...

This report discusses a case of 15 years oldyoung boy who surprisingly presented late with huge congenital diaphragmatic hernia having stomach, part colon, small bowel, spleen, tail pancreas and left kidney.

Introduction Atresia of the colon is an uncommon entity distinct from congenital pouch colon, which is a more frequent occurrence in India and Asia, and is associated with anorectal malformations. Although the underlying cause of colonic atresia may be vascular insufficiency, the association with Hirschsprung’s disease, in particular, and the gross discrepancy between the proximal and distal bo...

introduction: computed tomography (ct) is an imaging technique with gives us an opportunity to review cross sections of the body in live animals. in veterinary medicine although ct is mostly used for diagnostic purposes in small animals, but in recent years ct also has been used as a non invasive modality in non clinical studies. jebeer gazelle (gazella bennettii) is one of the species of the g...

FIG. 1.-Case 1. Radiograph of abdomen showing immense faecal distension of caecum, ascending colon, and hepatic flexure. The collapsed bowel distal to the colostomy has been outlined by barium for comparison. FIG. 2.-Case 2. Radiograph showing faecal distension of hepatic flexure. FIG. 3.-Case 3. Radiograph of abdomen showing multiple fluid levels throughout small bowel together with marked fae...

A research model has been devised to assist in an assessment of the relative susceptibility of small bowel and colonie mucosa to potential intestinal carcinogens, and an application of this model to azoxymethane is reported. Intestinal transpositions were performed on Sprague-Dawley rats. In one group, segments of small intestine were transposed to the ascending and descending colon and, in ano...
