The compound 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS) is an efficient anion exchanger inhibitor that can block the activities of anion exchanger 2 (AE2), which plays an indispensable role in gastric acid secretion. DIDS also has potent anti-oxidative and antiapoptosis activities. This study aimed to investigate the effect of DIDS on ethanol-induced mucosal damage in rats and to e...
The effect of 16,16-dimethyl prostaglandin E2 (dmPGE2) on gastric surface epithelial cell (SEC) damage induced by vagal nerve stimulation (VS) in urethane-anesthetized rats was studied using scanning electron microscopy. VS (1.25-10 Hz, 0.2 mA, 2 msec, 10 min) resulted in a graded increase in the SEC damage, increased gastric contractions, increased gastric acid secretion, and a decrease in hea...
BACKGROUND This study evaluates the effect of eradicating Helicobacter pylori on basal and bombesin-stimulated gastric acid secretion and serum gastrin in non-ulcer dyspepsia. METHODS Before and 1 month after an attempt to eradicate H. pylori basal and bombesin-stimulated gastric acid outputs were measured in 23 patients. H. pylori was eradicated in 15 patients (group A) but not in the other ...
We examined the effect of L-lactic acid on calcium absorption in male Wistar rats made achlorhydric by dietary omeprazole, a proton pump inhibitor. The dietary omeprazole intake (0.03 g/100 g of diet) increased the gastric pH and decreased the apparent calcium absorption ratio. Dietary famotidine (0.03 g/100 g of diet), an H2-receptor antagonist, and lower doses of omeprazole (0.005 or 0.01 g/1...
The possible effects of organic acids or an organic salt on the rate of gastric emptying was studied to identify the cause for reduced postmeal responses of blood glucose and insulin to foods containing such components, eg, sourdough bread. Paracetamol was included in bread products with added lactic acid or sodium propionate and used as a marker for the rate of gastric emptying in healthy subj...
Studies of gastric acid secretion and mucosal appearances have been made in a group of 14 patients suffering from hypopituitarism. Achlorhydria was found in six of the patients suffering from Addison's disease but in only one patient suffering from hypopituitarism. In both groups the mean gastric secretion of hydrochloric acid was considerably lower than in a group of control subjects and repla...
The role of histamine in acid secretion is controversial. Improvements in the techniques of histamine assay allow a better assessment of the relationship of histamine to acid secretion. Patients with duodenal ulcers were studied to determine the mucosal histamine responses to pentagastrin stimulation to relate the appearance of histamine in the gastric juice to acid production during stimulatio...
ABSTRACT Introduction: Formation of gastric ulcer is a multifactorial process so that vascular changes, mucous secretion, gastric acid and gastrointestinal tract mucous biochemistry are involved in gastric ulcers. Despite therapeutic properties, ibuprofen as a non-steroidal anti-inflammatory drug (NSAID) can cause mucosal lesions in the stomach. In this study, the effect of Matri...
Abstract Background Folic acid modulates gastrointestinal inflammatory disorders via a number of suggested gastroprotective mechanisms. Gastric acid, inflammation, cell proliferation and angiogenesis play significant role in gastroprotection restoration mucosal integrity following injury. This two-section-study assessed (1) output, parietal mass, neutrophil infiltration inflammation after 6 h p...
Somatostatin (cyclic growth-hormone release-inhibiting hormone--GH-RIH) was infused into dogs with gastric fistulae. Somatostatin inhibited gastric acid response to four gastric stimulants--insulin, food, histamine, and pentagastrin. Histamine- and pentagastrin-stimulated pepsins were inhibited similarly to inhibition of acid. Somatostatin inhibited the gastrin response to insulin and food.
