Free radicals play an important role in stomach ulcer formation. The present investigation validates the anti ulcer activity of hesperidin, isolated from Citrus sinensis (L.) Osbeck, Rutaceae, through the assessment of its antioxidant potential over stomach mucosal tissue by histological examination. Hesperidin was isolated from the dried peel of C. sinensis, and authenticated by TLC, IR and HP...

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...

This study investigated the gastroprotective effect of Lcarnitine against indomethacin-induced gastric ulcer in rats and the possible mechanisms underlying this effect. Two sets of experiments were performed. In the first set male albino rats (170-210 g) were randomly allocated into a normal control group, ulcer control group (received a single dose of indomethacin 30 mg/kg po) and three ulcer ...

BACKGROUND/AIMS Folic acid modulates several disorders in humans. We investigated the effects of folic acid supplementation at varying doses on ulcer formation in the rat. MATERIALS AND METHODS Male Wistar rats were treated with 1 mg/kg, 2 mg/kg and 3 mg/kg diet of folic acid for 21 days. Gastric ulceration was induced by indomethacin, scored, and assayed to determine the concentration of muc...

The aim of the study was to study the anti-ulcer activity of the methanolic extract of the leaves of Capparis zeylanica Linn on experimental animal models. The methanol extract of Capparis zeylanica Linn. leaves was investigated for anti-ulcer activity against aspirin plus pylorus ligation induced gastric ulcer in rats. HCl-Ethanol induced ulcer in mice and indomethacin induced ulcer in rats at...

The pathogenesis of gastric mucosal injury is still poorly understood. Recent reports implicate redox active metals and reactive oxygen species as mediators of gastric damage induced by ethanol or non-steroidal anti-inflammatory drugs. Attempts were made therefore to prevent gastric injury using chelators and the antioxidant enzymes catalase and superoxide dismutase. These attempts, at best, wo...

Purpose: To investigate the activity of Feronia elephantum fruit pulp extract (which is used in folk medicine) against indomethacin-induced gastric ulcer in rats. Methods: The fruit pulp was extracted with ethanol and the anti-ulcer activity of the extract in indomethacin-induced gastric ulceration in Swiss albino rats was evaluated. The parameters assessed were pH and acid concentration of gas...

We compared the effects of an anti-ulcer agent, benexate hydrochloride betadex (BHB), on prostaglandin (PG) levels in gastric tissue and inflammatory exudate in untreated and indomethacin-treated rats. BHB (100, 300 and 1000 mg/kg, p.o.) showed dose-dependent inhibition of gastric mucosal lesions induced by indomethacin (30 mg/kg, p.o.). Sustained decrease of PGs (PGE2 and 6-keto-PGF(1alpha)) i...

Background: Several plants are used as analgesic in traditional medicine. Capparis spinosa (C. spinosa) is widely for the treatment of gout and rheumatic arthritis. The previous studies have reported antinociceptive effects this plant. Objectives: study was aimed at examining C. spinosa’s gastric-ulcerogenecity effect comparison to indomethacin. Methods: percolated extract Indomethacin were ora...

In this study, the anti-inflammatory and anti-ulcerative effects of metyrosine, a selective tyrosine hydroxylase enzyme inhibitor, were investigated in rats. For ulcer experiments, indomethacin-induced gastric ulcer tests and ethanol-induced gastric ulcer tests were used. For these experiments, rats were fasted for 24 h. Different doses of metyrosine and 25 mg/kg doses of ranitidine were admini...
