introduction: the protective and antisecretory effects of dopamine agonists on the stomach have been already reported, but the effect of bromocriptine (d2 dopamine agonist) on histamine stimulated gastric acid secretion (gas) needs to be investigated. methods: for gastric sampling, animals were anesthetized and a polyethylen tube was introduced into the stomach through esophagus. a cannula was ...

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...

Introduction: The effect of esophageal distension (ED) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ED on gastric secretion. The aim of this study was to investigate the effect of ED on gastric acid and pepsin secretion and the mechanism(s) involved. Methods: Male adult Wistar rats (200-240 g) were anesthetized with urethane (1...

background: opioid peptides and their receptors are present in the majority of body tissues including gastrointestinal tract.  heroin is one of the opioid derivatives that abuse increasingly today.  so far, there is no study on the effect of acute heroin administration on gastric acid and pepsin secretion.   objective:  to define the effect of the acute heroin consumption on basal and vagal-sti...

background many studies have shown that h2s protects the gastric mucosa on different models of stress but till now there are few studies about the effects of h2s on gastric acid secretion. therefore, the aim of the present study was to investigate the role of autonomic nervous system in mediating the inhibitory effect of hydrogen sulfide donor (nahs) on stimulated gastric acid secretion in rats...

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...

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 ...
