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 ...

OBJECTIVE To study the effect of nimesulide on acid secretion in mouse isolated stomach. METHODS Isolated lumen-perfused mouse stomachs were monitored by pH-electrodes (1). Gastric acid secretion was stimulated with histamine or 5-methylfurmethide (5-MeF, a stable acetylcholine derivative), and the effect of nimesulide and indomethacin were studied alone and in combination with famotidine. ...

In this study, albino Wistar rats were placed on normal rats chow + drinking water and/or 500mg/kg, 1000mg/kg body weight of the Ocimum gratissimum extract orally, once daily for 28 days and gastric acid, mucus and ulcers determined. All the rats received normal rat chow + drinking water ad libitum for 28 days. Gastric acid, mucus secretion and ulcer scores were determined with standard procedu...

Ascorbic acid is one of the most well-known nutritional supplement and antioxidant found in fruits and vegetables. Calcium ascorbate has been developed to mitigate the gastric irritation caused by the acidity of ascorbic acid. The aim of this study was to compare calcium ascorbate and ascorbic acid, focusing on their antioxidant activity and effects on gastric juice pH, total acid output, and p...

Upper gastrointestinal function in response to a mixed nutrient meal was evaluated in hyperthyroid patients, both before and after therapy, and in healthy controls. Gastric secretion, gastric emptying, and pancreatic secretion were all normal and normally integrated postprandially in the hyperthyroid patients. Bile acid output was reduced (P less than 0.05) in this group of patients relative to...

OBJECTIVE Gut-brain axis (GBA) is very important in creation and modulation of gastrointestinal problems. Aloe vera gel has gastroprotective properties. The purpose of this study was to evaluate the effect of aqueous extract of Aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. MATERIALS AND METHODS Gastric ulce...

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 ...

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...

This study examined the effects of eradication of Helicobacter pylori (H pylori) infection on gastric mucosal morphology and acid secretion. Sixteen H pylori positive patients with enlarged gastric body folds were divided into two groups: (a) patients with moderate enlargement (fold width: 6 to 10 mm, n = 8) and (b) patients with severe enlargement (> 10 mm, n = 8). After successful treatment, ...

Peak acid outputs in normal subjects and patients with duodenal and gastric ulcer were significantly (and similarly) correlated with body weight and calculated lean body mass. Expression of measurements of peak acid output as a function of body weight or lean body mass lessened but did not abolish the significance of the situation that men with no dyspepsia or gastric ulcer secreted more acid t...
