Helicobacter Pylori infection has been identified as a pathogenic factor in a number of gastroduodenal diseases, most importantly in gastric and duodenal ulcer disease. This association and the development of H. PYLORI eradication therapies has had a tremendous influence on the surgical therapy for these disorders. Decades ago, surgery was the therapy of choice for gastric and duodenal ulcers. ...

Frequently used for humans as non-steroidal anti-inflammatory drug, naproxen has been known to induce ulcerative gastric lesion. The present study investigated the in vivo protective effect of astaxanthin isolated from Xanthophyllomyces dendrorhous against naproxen-induced gastric antral ulceration in rats. The oral administration of astaxanthin (1, 5, and 25 mg/kg of body weight) showed a sign...

Background: Evidences show that Aloe vera (A. vera), Camellia sinensis, Hibiscus sabdariffa and Sophora alopecuroides may prevent gastric ulcer induced by non-steroidal anti-inflammatory drugs (NSAIDs). Objective: To examine the protective potential of these plants against indomethacin-induced gastric ulcer in the rat. Methods: Saline, A. vera leaf gel powder and 70% alcoholic extracts of...

The pronounced geographical and temporal variations in gastric and duodenal ulcer suggest that important environmental factors must play a part in their aetiology. To determine the nature of possible factors, the Registrar General's decennial supplement and the vital statistics special reports of the United States Department of Health, Education, and Welfare on occupational mortality were analy...

This study reports the electrophoretic pattern of the proteins in human gastric juice of control patients and patients with gastric ulcer and gastric carcinoma. Autodigestion was prevented by intragastric neutralization. The statistical limits of normal are defined and the changes found in the gastric juice of gastric ulcer and gastric patients with gastric carcinoma described.

Measurements were made of the amounts of histamine extracted from patients with peptic ulcer disease and control subjects suffering from various gastrointestinal diseases. Patients with duodenal ulcer, gastric ulcer, or recurrent duodenal ulcer after proximal gastric vagotomy often had less gastric mucosal histamine than did normal controls. Cimetidine therapy increased the amounts of the hista...

Aim: To investigate the protective effect of sildenafil citrate, a selective inhibitor of cyclic guanosine monophosphate-specific phosphodiesterase, on gastric mucosal damage induced by cold restraint stress (CRS) in rats. Further, the study was extended to investigate some possible mechanisms underlying this effect. Material and Methods: Forty rats were randomly divided into 4 groups. Normal c...

Upper gastrointestinal tract integrity is dependent upon the delicate balance between naturally occurring protective factors as mucus or prostaglandins and damaging factors as hydrochloric acid present normally in the digestive juices. An imbalance causes peptic ulcer formation and destruction of gastrointestinal tract mucosal lining. Ulcer may develop in the esophagus, stomach, duodenum or oth...

Mesenchymal stem cells (MSCs), a subpopulation of adult somatic stem cells, are an attractive stem cell source in regenerative medicine because of their multipotentiality. We examined the effects of MSC transplantation on gastric ulcer healing. Putative MSCs, isolated from bone marrow aspirates of male rats by dish adherence and expanded in culture, were characterized by flow cytometry and reve...
