Simvastatin appeared to have additional benefits beyond their lipid lowering effects, which has led to interest in the use of this class of drugs outside the field of cardiovascular disease. Aim: This study aimed to investigate the possible gastroprotective effect of simvastatin against both indomethacin and cold restraint stress (CRS) induced gastric ulcers in rats and to study its effect on g...

The herbal medicines derived from various plants extracts are being increasingly utilized to treat a wide variety of clinical diseases 1 . Besides their action as gastroprotectives, flavonoids also act in healing of gastric ulcers 2 . The study was designed to investigate the anti-ulcer effect of chloroform extract of Chrozophora plicata leaves (600mg/kg) against experimentally induced ulcer mo...

Crocin is a plant-derived carotenoid and bears potent antioxidant property. Ranitidine (a histamine H2 receptor blocker) is used for peptic ulcer treatment. The present study was planned to investigate the effects of crocin and ranitidine on indomethacin-induced ulcer in small intestine of rats. Animals were randomized into two major groups including indo-methacin (10.00 mg kg-1...

Introduction : Peptic ulcer occurs more frequently in men than in women, sex differences are less marked after 45 years of age probably because the incidence of ulcer increases in post menopausal women. The general assumption is that the ulcer differences between sexes are related in some way to sex hormones and that the female sex hormones protect against ulceration. The aim of the this study ...

Abstract Ghrelin has been shown to ameliorate gastric injury by several mechanisms in experimental animal models. The present study aimed to investigate the effect of pretreatment with ghrelin on indomethacin induced gastric injury in rats and the role of heme oxygenase -1(HO-1) pathway as a novel mechanism underlying the gastroprotective effect of ghrelin. In all groups studied, ulcer score (U...

The effect of different extracts of leaves and fruits of Moringa oleifera Lam. (Moringaceae) on gastric and duodenal ulcers was evaluated by using different gastric ulcer models and cysteamine-induced duodenal ulcer method. The leaf extracts (500mg=kg, p.o.) of Moringa oleifera showed gastric ulcer healing effect in acetic acid–induced chronic gastric ulcers. The acetone extract and methanol ex...

Objective: Zataria multiflora has been reported to have several medicinal properties including antioxidant, antibacterial, antispasmodic, and expectorant activities. This study aimed to investigate the effect of Z. multiflora hydro-alcoholic extract (ZMHE) on peptic ulcer caused by indomethacin in rats. Materials and Methods: ZMHE was prepared by maceration,  condensed by rotary evaporator and ...

BACKGROUND/AIMS There are increasing evidences for gastrointestinal motility disorder (GIMD) and gastric stress ulcer induced by noise stress. The present study was to investigate the reversed effect of melatonin on GIMD and gastric stress ulcer induced by noise stress and potential mechanism. METHODS Noise stress was induced on rats, and melatonin (15 mg/kg) was administered to rats by intra...

Tricyclic antidepressants are particularly useful in the treatment of endogenous depression. Since the 1950s, tricyclic antidepressants (TCAs) have also been used for the treatment of gastric ulcer disease. Many TCAs have been evaluated for their antiulcer effects, but there are presently no data in the literature specifically concerning the antidepressant opipramol. This study aimed to investi...
