Prostaglandin analogues of the E-series theoretically offer the ideal antiulcer drugs. Peptic ulcer healing with prostaglandin analogues is, however, no better than would be predicted from their ability to inhibit gastric acid secretion and they are less effective than histamine H2 receptor antagonists in preventing ulcer relapse. It could be that prostaglandin analogues inhibit gastric mucosal...

The gastric output of acid and pepsin in response to two doses of the cholinergic drug carbachol was measured before and two months after complete truncal vagotomy and pyloroplasty in eight patients with duodenal ulcer. After vagotomy the basal output of acid and pepsin was reduced and there was no stimulation of secretion by a subthreshold dose of carbachol (0.5 units/kg) nor was there an incr...

This study was undertaken to determine the role of cholecystokinin in pancreatic enzyme secretion stimulated by bombesin and a meal by (a) comparing the pancreatic enzyme output during bombesin infusion and after a meal to output during caerulein infusion and (b) comparing the inhibitory effect of the cholecystokinin-receptor antagonist lorglumide (CR-1409) on enzyme output in response to bombe...

Relationships between the NO synthase inhibitor and gastric and pancreaticobiliary functions measured simultaneously in the digestive state have been little studied. The aim of this study was to estimate the effect of NO synthase inhibitor on integrated digestive function in conscious dogs. A strain gauge force transducer was implanted on the gastric antrum of 6 mongrel dogs to measure gastric ...

Accepted for publication 30 April 1990 Abstract This study was undertaken to determine the role of cholecystokinin in pancreatic enzyme secretion stimulated by bombesin and a meal by (a) comparing the pancreatic enzyme output during bombesin infusion and after a meal to output during caerulein infusion and (b) comparing the inhibitory effect of the cholecystokinin-receptor antagonist lorglumide...

In this study, we investigated the inhibitory activities on gastritis and gastric ulcer using liriodendrin which is a constituent isolated from Kalopanax pictus. To elucidate its abilities to prevent gastric injury, we measured the quantity of prostaglandin E2 (PGE2) as the protective factor, and we assessed inhibition of activities related to excessive gastric acid be notorious for aggressive ...

The control of gastric pepsin secretion continues to excite controversy. The diversity in the results obtained by different investigators may be due, at least in part, to the varying techniques employed to estimate pepsin activity. Thus, edestin (Polland and Bloomfield, 1929), gelatin (Gilman and Cowgill, 1930), egg albumen (Vineberg and Babkin, 1931), beef haemoglobin (Anson and Mirsky, 1932),...

Cimetidine has been shown to stimulate prolactin secretion after a intravenous administration. Cimetidine 200 mg and ranitidine 50 mg was given i.v. in a randomly allocated order to 22 volunteers on consecutive days; these doses can be regarded as equivalent as far as inhibition of gastric acid output is concerned. Plasma prolactin was estimated at regular intervals. The prolactin stimulating e...

BACKGROUND Further elucidation of the consequences of Helicobacter pylori infection on gastric mucosal inflammation and gastric secretory function would be facilitated by an animal model that is susceptible to infection with H. pylori, is broadly similar in gastric physiology and pathology to people, and is amenable to repeated non-invasive evaluation. The goal of this study was to examine the ...
