ba ckground: although some studies have shown positive effects of omega-3 fatty acid supplementation on nutritional status of cancer patients undergoing different treatments, there is no consistency in results. the aim of this study was to examine the effects of omega-3 fatty acid on the nutritional status of gastric cancer patients during the course of chemotherapy. m ethods : in a double-blin...

Objective(s): Prostaglandins have been shown to mediate the gastro-protective effect of sodium hydrosulfide (NaHS) but effect of NaHS on mRNA expression of prostaglandin E2 receptors (EP1, 3-4; EPs) has not been investigated. Therefore, this study designed to evaluate the effect of NaHS on mRNA expression of EPs receptors in response to mucosal acidification and distention-induced gastric acid ...

CONTEXT Causal factors of gastrojejunal ulcers after Roux-en-Y gastric bypass include peptic acid secretion from the gastric pouch. Esomeprazole is a potent inhibitor of acid secretion. OBJECTIVE To assess the occurrence of dyspepsia and gastrojejunal ulcers within the first 2 months after Roux-en-Y gastric bypass during the use of esomeprazole. METHODS One hundred eighteen morbid obese sub...

5 roton pump inhibitors (PPIs) suppress gastric acid secretion by selectively inhibiting the enzyme P hydrogenepotassium adenosine triphosphatase, located in gastric parietal cells. These drugs superseded H2-receptor antagonists as first-line acid suppressants in the 1980s, and their potent effect has revolutionised the management of common upper gastrointestinal (GI) disorders, including gastr...

Introduction: Garlic (Allium Satiyum) is a plant widely used in traditional medicine. Its anti-hypertensive, lipid lowering, oxidative activities, anti-viral, anti-bacterial, anti-fungal properties have been proven. It has a tonic effects on stomach but its effects on gastric secretion is not known. Propose of study: To investigate the effect of garlic extract on basal and pentagastrin stimulat...

The gastric glands of Triturus carnifex (Amphibia, Caudata) have been examined by histochemical and immunohistochemical methods with particular regard to hydrochloric acid and pepsinogen secretion. Fundic glands consist of mucous neck cells, endocrine cells and oxynticopeptic cells producing both pepsinogen and hydrochloric acid. The neck cells showed an unexpected distribution pattern which wa...

Sonic hedgehog (Shh) is found within gastric parietal cells and processed from a 45-kDa to a 19-kDa bioactive protein by an acid- and protease-dependent mechanism. To investigate whether Shh is associated with the parietal cell membrane compartment that becomes exposed to both acid and proteolytic enzymes during acid secretion, the cellular location of Shh within resting and stimulated gastric ...

noise is considered as one of the most severe sources of environmental and work place constraints. noise effects on immune function, hormonal levels, cardiovascular and respiratory systems are well known. the aim of the study is to evaluate the effects of traffic noise on basal and stimulated gastric acid secretion. 48 healthy rats were divided into five traffic noise exposures (1, 7, 14, 21, 2...

tion of connective tissue mast cells, but not mucosal mast cells, with release of serotonin and histamine from the cells. We have shown in rats with a single C48/80 treatment that the development of gastric mucosal lesions occurs with decreases in Se-glutathione peroxidase (Se-GSHpx) activity and vitamin E and hexosamine levels and increases in neutrophil infiltration, xanthine oxidase (XO) act...

Introduction Gastric ulcer disease has been recognized in foals and adult horses. It is a complex disease and lesions vary in anatomic distribution, severity and cause. In the neonatal foal (<30 days of age) gastric ulcers and mucosal desquamation have been documented in clinically normal foals [1-4]. Due to this finding many clinicians feel it is necessary to treat critically ill neonates prop...
