When the barrier to acid back-diffusion is disrupted, there is a protective increase in gastric mucosal blood flow to help remove the back-diffusing acid. Only recently has the mechanism for calling forth this protective hyperemia been determined. The gastric mucosa and submucosa are innervated by many capsaicin-sensitive sensory nerve fibers containing vasodilator peptides. The gastric mucosal...
This study was designed to determine the gastroprotective properties of quercetin in ischemia/reperfusion-induced gastric mucosal injury and the involvement of endogenous prostaglandins in this process. Oral pretreatment of rats with quercetin (100 mg x kg(-1)) 30 min before surgery significantly decreased the length of gastric mucosal lesions. However, lower doses of quercetin (25 and 50 mg x ...
objective(s) several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. in the present study, we aimed to investigate the gastroprotective potential of either per...
Diabetic gastroparesis is associated with increased oxidative stress attributable to loss of upregulation of heme oxygenase-1 (HO1), with resultant damage to interstitial cells of Cajal and delayed gastric emptying. These changes can be reversed by induction of HO1. HO1 catalyzes the breakdown of heme into iron, biliverdin and, carbon monoxide (CO). The aim of this study was to determine whethe...
In the present study, we examined the gastroprotective effect of selenium against ethanol-induced gastric mucosal lesions in rats. The gastric mucosal lesions were produced by oral administration with various concentrations of ethanol for three days, and 80% ethanol treatment was determined to be the optimal condition for induction of gastric damage. To identify the protective effect of seleniu...
The present study was designed to compare ulcer protective effect of proton pump inhibitors viz. omeprazole, rabeprazole and lansoprazole against dexamethasone plus pylorus ligation induced ulcer model. Dexamethasone (5 mg/kg) was used as an ulcerogen. Dexamethasone suspended in 1% CMC in water was given orally to all the rats 15 min after the pylorus ligation. Omeprazole (20 mg/kg), rabeprazol...
This study was performed to evaluate the protective effect and safety of Oryeongsan water extract (OSWE) on ethanol-induced acute gastric mucosal injury and an acute toxicity study in rats. Acute gastric lesions were induced via intragastric oral administration of absolute ethanol at a dose of 5 mL/kg. OSWE (100 and 200 mg/kg) was administered to rats 2 h prior to the oral administration of abs...
clinically used for the treatment of gastric ulcers and gastritis. Takagi and Yano reported that when gefarnate was orally administered to fasted rats for 5 d, the level of hexosamine, an index of gastric mucus, in the pyloric tissue of the stomach increased and that the reduction of hexosamine content in the gastric pyloric tissue of rats with 3 d of water immersion restraint stress (WIRS) was...

Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract.
