Introduction: It has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of H2S, but till now the effect of duodenal acidification on gastric H2S release has not been investigated. Therefore, the present study designed to evaluate the effects of duodenal acidification on gastric H2S release and level of mRNA expression of cys...

introduction: lymphoma may involve the gastrointestinal tract either primarily or as a manifestation of extensively disseminated systemic disease. stomach being the most frequent site of primary gastroin-testinal lyphoma, followed by the small bowel and colon respectively (1&2&3). for diagnosis of pi-mary small intestinal lymphoma (psil), one most satisfies the criteria specified by dawson and ...

abstract background: gastric cancer is one of the most common cancers in our country. recent studies have shown that adenocarcinoma of the cardia and distal stomach has increased in the past 25 years. however demographic data is lacking in this regard. methods: this study is a retrospective case series study. all records from 460 consecutive patients who were documented pathologically to have g...

conclusions gastric pouch is a suitable segment for bladder cystoplasty and neobladder. continence is mostly related to the capacity of pouch. results postoperative complications were rare. continence was defined as bladder capacity over 400 ml. their follow-up period ranged from five months up to writing the article. one of the studied cases is still alive and awaiting renal transplantation. m...

Background & Objective: Gastric cancer is the second most frequent cause of cancer death worldwide, despite differences in incidence around the world. The majority of gastric cancer cases concern gastric adenocarcinoma, which has a fairly high 5-year survival rate when coupled with early-stage diagnosis. Versican, a member of the aggregating chondroitin sulfate proteoglycans fa...

Objective(s) The liver has major role in the organism homeostasis, interactions with other systems, synthesis and metabolism of bile production, drug detoxification and hormone inactivation. Cholestasis can be defined as an impairment of the bile flow which can lead to hepatocytes necrosis and finally cirrhosis. Some studies reported a gastric acid secretion reduction in cirrhotic subjects, wh...

Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...

Introduction: Sodium hydrosulfide (NaHS) has shown to enhance the gastric emptying rate in normal rats but till now its effect on gastric emptying of food stuffs in diabetic rats was not investigated. Therefore, this study designed to determine the role of an oral administration of NaHS on gastric emptying rate (GER) of glucose, albumin and olive oil in gastroparetic and normal rats. Methods: T...

it is well established that the esophageal distention (ed) leads to gastric relaxation, partly by vago-vagal reflex, but till now, the effect of ed on gastric acid secretion has not been investigated. the aim of this study was to investigate the effect of ed on basal and stimulated gastric acid secretion. methods: adult male wistar rats (200-240 g) were deprived of food but not the water 24 h b...
