A group of novel nitric oxide (NO) donating chalcone derivatives was prepared by binding various amino chalcones with different NO donating moieties including; nitrate ester, oximes and furoxans. Most of the prepared compounds showed significant anti-inflammatory activity using carrageenan-induced rat paw edema method compared with indomethacin. The prepared compounds exhibited more protection ...

Helicobacter pylori is an important risk factor for gastric cancer, gastric ulcer, and duodenal ulcer, yet most infected persons do not develop disease. We examined two correlates of acquisition age, sibship size and birth order, to evaluate the hypothesis that early life acquisition of //. pylori is a risk factor for the development of these illnesses. In earlier nested case-control studies of...

Anti gastric ulcer activity of root, stem and leaves of Amaranthus spinosus Linn. was studied against ethanol, hydrochloric acid, indomethacin, stress and pyloric ligation induced gastric ulceration in albino rats. Omeprazole was used as standard anti gastric ulcer drug. Significant anti gastric ulcer activity was noted in root, stem and leaves of Amaranthus spinosus Linn. Root of the plant, ho...

Context: In our previous study we have suggested that Rohitukine attenuates gastric mucosal injury; however its exact mechanism has not yet been established. Objective: The aim of present study was to evaluate the gastro protective mechanism of Rohitukine. Materials and methods: Sprague dawley rats and guinea pigs weighing 180–200 g were used. Dudenol ulcer was observed through Histamine induce...

Helicobacter pylori is an important risk factor for gastric cancer, gastric ulcer, and duodenal ulcer, yet most infected persons do not develop disease. We examined two correlates of acquisition age, sibship size and birth order, to evaluate the hypothesis that early life acquisition of H. pylori is a risk factor for the development of these illnesses. In earlier nested case-control studies of ...

AIM To explore the roles of nitric oxide synthase (NOS), heme oxygenase (HO) and cyclooxygenase (COX) in gastric ulceration and to investigate the relationships of the expression and activities of these enzymes at different stages of gastric ulceration. METHODS Gastric ulcers (kissing ulcers) were induced by luminal application of acetic acid. Gastric tissue samples were obtained from the ulc...

A previous study has demonstrated that locally administered growth factors such as epidermal growth factor, basic fibroblast growth factor and hepatocyte growth factor can accelerate healing of experimental gastric ulcers in rats. That study indicates that locally administered growth factors can exert potent biological effects resulting in enhanced gastric ulcers healing. However, the fate of i...

Aloe buettneri A. Berger is commonly used in traditional Togolese medicine to treat inflammatory and gastric ulcers. The present study examined the gastro-protection effect of the hydro-alcoholic extract of A. buettneri on mucus production and gastric pH. A gastric ulcer is induced by ethanol 95° alone (1 mL/kg body weight), after pre-treatment with indomethacin (300 mg/kg) or by utilising L-NA...

Recurrent, peptic ulcer following surgery has a 3% to 10% recurrence rate. Recurrence is due to one of the following causes: incomplete vagotomy, failure of gastric drainage, inadequate gastric resection, Zollinger-Ellison syndrome, hyperplasia of the antral gastric-secreting cells or due to use of nonabsorbable sutures. Lack of or incomplete vagotomy has been the most common cause. Gastric ulc...
