introduction: recently, hydrogen sulfide has been introduced as the third gas that acts as a transmitter. it has many physiological and pharmacological roles in the human body. the aim of the present study was to investigate the effect of exogenously administered and endogenously produced h2s on the basal and distention-induced gastric acid secretion in rats. methods: forty-nine male wistar rat...

sub chronic exposure to lead in rats slows gastric emptying, but little is known about the effects of lead on gastric secretion. this study was designed to investigate the effects of lead on gastric acid secretion and its possible mechanisms in rats. lead acetate was dissolved in drinking water in a concentration of 1%. sodium acetate-containing water with a molar concentration similar to lead ...

abstract injection of sulpiride (d2 receptor antagonist, antipsychotic drug) into vmn hypothalamus, increased gastric volume secretion and decreased gastric ph. the present study the effect of sch23390 (d1 dopamine receptor antagonist) on the gastric acid secretion and its acidity were studied. 70 rats were divided into 7 groups: two control groups, two sham groups given medicine solvents, a sc...

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...

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 ...

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 ...

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, whi...
