[ 1 ] - اثر اتساع مری بر ترشح پایه و تحریک شده اسید معده در موش صحرائی
زمینه: بخوبی اثبات شده است که اتساع مری از طریق رفلکس واگی- واگی موجب شل شدن معده میگردد. با این وجود تاکنون در مورد تأثیر این رفلکس بر عملکرد ترشحی معده تحقیقی انجام نشده است. هدف از مطالعه حاضر بررسی اثر اتساع مری بر ترشح پایه و تحریک شده اسید معده میباشد. مواد و روشها: موش های صحرائی نر از نژاد ویستار (Wistar) با وزن تقریبی 240-200 گرم، ۲۴ ساعت قبل از آزمایش تحت گرسنگی قرار میگرفتند. ...
[ 2 ] - Effect of Esophageal Distention on Basal and Stimulated Gastric Acid Secretion in Rats
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...
[ 3 ] - Effect of esophagus distension on gastric blood flow, gastrin and somatostatin secretion in rat
Abstract Introduction: There are many studies about the inhibitory effect of the esophageal distention (ED) on gastric motility. Recently, it has been shown that ED decreases the gastric secretions. It is well established that the inhibitory effect of ED is mediated by activation of vago-vagal inhibitory reflex. However, there is not any investigation about the effect of the reflex on the gast...
[ 4 ] - Effect of esophageal distension on gastric secretions in rat and the possible mechanism
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...
[ 5 ] - Gastroprotective effect of Alhagi camelorum on experimental gastric ulcer in rats

The present study was undertaken to evaluate the Alhagi camelorum aqueous extract for anti-ulcer activity in rats. Methods: Male Wistar rats were pretreated with the A. camelorum aqueous extract (150, 300 or 450 mg/kg of B.W., P.O.) before induction of gastric ul...
