Gastric ulcer is a multifaceted, pluricausal illness. Knowledge of the pathophysiology of gastric ulcer disease remains incomplete. Current pharmacological management of gastric ulceration is directed primarily at the reduction or neutralization of gastric acid secretion despite evidence that patients with this disease often exhibit normal gastric secretory activity. Attempts have been made to ...

BACKGROUND: Gastric ulcer is one of the most common diseases in racehorses. Colic, weight loss and poor performance are some of the clinical signs. The second and third larval stages of the bot fly Gasterophilus spp live in the stomach of the horse. This parasite is often found in large numbers of horses in all of the countries. OBJECTIVES: The a...

The effect of alcoholic extract of Nigella sativa was investigated in rats to evaluate the anti-ulcer activity by using two models, i.e. pyloric ligation and aspirininduced gastric ulcer. The parameters taken to assess anti-ulcer activity were volume of gastric secretion, free acidity, total acidity and ulcer index. The results indicate that the alcoholic extract significantly (P < 0.001) decre...

BACKGROUND It is presently not well understood to what extent peptic ulcer and gastric cancer represent related diseases. AIMS The objective of this study was to assess past occurrence of gastric and duodenal ulcers in patients with cancer of the gastric cardia or other parts of the stomach. METHODS The association between peptic ulcer and gastric cancer was studied among patients followed ...

Carbenoxolone sodium was studied to determine its effect against restraint-induced gastric mucosal damage in the rat. Significant anti-ulcer activity was observed following intraperitoneal administration in nonfasted but not in either 24 or 48 h fasted rats. Orally, carbenoxolone had no statistically significant effect in non-fasted rats although the data suggest that it may have afforded some ...

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...

Gastric mucins are high molecular weight extracellular glycoproteins that play a major role in the protection of the gastrointestinal tract and besides that they are also involved in many disease processes. In the present study, size exclusion chromatography under non-degrading conditions was used to study the fragmentation pattern of native gastric mucins. The samples of gastric mucins of diff...

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 o...

Background: CD1d presents glycolipid antigens to invariant natural killer T (iNKT) cells. The role of CD1d in the development of peptic ulcer and gastric cancer has not been revealed, yet. Objective: To clarify the expression of alternatively spliced variants of CD1d in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dys...

Sodium/hydrogen exchanger (NHE) 8 is an apically expressed membrane protein in the intestinal epithelial cells. It plays important roles in sodium absorption and bicarbonate secretion in the intestine. Although NHE8 mRNA has been detected in the stomach, the precise location and physiological role of NHE8 in the gastric glands remain unclear. In the current study, we successfully detected the e...
