BACKGROUND Cell migration (restitution) occurs in the early phase of gastric ulcer healing. Tumor necrosis factor (TNF)-alpha is overexpressed at the ulcer margin and plays a physiologic role in gastric ulcer healing. Dexamethasone, which is a potent corticosteroid, delays rat gastric ulcer healing. We evaluated whether dexamethasone inhibited TNF-alpha-stimulated gastric epithelial cell migrat...

Gastric ulcer healing is a complex process that is regulated by several promoting factors including COX-2 and iNOS. Diabetes mellitus is usually associated with delayed gastric ulcer healing. Hence, the current study was designed to investigate the effect of sitagliptin (dipeptidyl peptidase-4 inhibitor) on gastric ulcer healing and expression of iNOS and COX-2 in rat stomach.The study was cond...

Falcaria vulgaris is a member of Umbelliferae family and is used for treatment of stomach disorders in the folk medicines of the west of Iran. This study was designed to evaluate the gastroprotective effect of F. vulgaris extract on ethanol (%50) induced gastric ulcers in rat. Thirty five young white male rats were divided to five groups (7rats/ group).Three case groups received plant extract (...

introduction: indomethacin increases generation of mitochondrial reactive oxygen species (ros) which have a crucial role in the indomethacin-induced gastric ulcer. coenzyme q10 has an antioxidant activity on mitochondria and cell membranes and protects lipids from oxidation and is essential for stabilizing biological membranes. superoxide dismutase (sod) acts as one of the defense mechanisms ag...

the antiulcer effects of different tricyclic antidepressants (trimipramine, doxepin, imipramine, and amitriptyline) in comparison with those of cimetidine, pirenzepine and omeprazole were investigated in male rats with acute gastric ulcer. acute gastric ulcer was induced by oral administration of o. 6n hcl solution, 1 ml/rat. pretreatment of animals with doxepin, trimipramine, amitriptyline, im...

Introduction: Alhagi camelorum belongs to the Leguminosae family is used in Iranian folk medicine to treat some gastric diseases. 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...

The susceptibility of healed, experimental gastric ulcers to chemical carcinogenesis was investigated. Slowly healing gastric ulcers were induced by the acetic acid method in the fundic and pyloric gastric mucosae of inbred male Wistar rats. N-Methyl-N'-nitro-N-nitrosoguanidine (MNNG) was administered in drinking water at a concentration of 50 mg/liter for 360 days after ulcer induction. Twenty...

Experimental evidence was provided to demonstrate the relationship between blood sugarlevel and stress-induced gastric ulcers in the albino rat; the stress employed being emotional (restraint) (i), In this paper are reported the results of experiments to demonstrate theinfluence of blood sugar level on volume of gastric contents, acidity and ulcer production In the stomach of the albino rat fol...

The aim of this study was to investigate the effect of fenugreek seeds on aspegic induced gastric mucosal ulcer in rats. Forty-eight male albino rats of Sprague Dawley strain were classified into normal control group and five aspirin induced gastric ulcer groups which divided into non treated control (+ve) and treated groups that were drug, fenugreek seeds extract, fenugreek oil and fenugreek p...

OBJECTIVE To determine the potential antiulcer activity of methanol extract of Melastoma malabathricum leaves (MEMM) using various established rat models. MATERIALS AND METHODS Ten groups of rats were used and orally administered 10% DMSO (negative control), 100 mg/kg ranitidine (positive control) or MEMM (50, 250 and 500 mg/kg) followed by gastric ulcer induction either using ethanol or indo...
