BACKGROUND/AIMS The role of H. pylori in the pathogenesis of ulcer disease in cirrhotic patients is poorly defined. Therefore, we sought to investigate the prevalence of H. pylori infection and the occurrence of gastroduode-nal lesions in patients with liver cirrhosis. METHODS AND PATIENTS Seroprevalence of H. pylori was tested in 110 patients with liver cirrhosis and 44 asymptomatic patients...

Glycyrrhiza glabra L. is used in folk medicine for treatment of stomach disorders includingpeptic ulcers. The hydroalcoholic extract of Glycyrrhiza glabra L. (HEGG) was evaluated forantiulcerogenic activity and acute toxicity profile in mice. Various doses of HEGG (50-200mg/kg) were administered orally to animals of different groups. Omeprazole and cimetidine atdoses of 30 and 100 mg/kg were us...

Helicobacter pylori infection is present in almost all patients with duodenal ulcers and 80-90% of patients with gastric ulcers, whereas the prevalence of infection among young adults without a history of ulcer is fairly low in Western countries. To investigate the importance of transmission from parent to child we assessed the relation between a parent’s history of gastric or duodenal ulcer an...

23 8 0 31 Summary of the Madras statistics. (1) The number of gastric operations has increased from 8 in 1918 to 260 in 1926. (2) The total of all admissions for these ulcers has increased from 205 in 1922 to 422 in 1926. (3) There was a sudden increase in gastric operations from 12 in 1921 to 132 in 1922. (4) All duodenal ulcers are admitted to the surgical wards and two out of three undergo o...

Hormonal peptides like ghrelin, orexin A (OXA) or nesfatin-1 not only regulate appetite, which is their basic biological function, but also contribute to mechanisms responsible for maintaining integrity of the gastric mucosa. Previous studies including those from our laboratory have revealed that their gastroprotective effect results from cooperation with other factors responsible for protectio...

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 ...

Gastrointestinal symptoms are a common manifestation of adverse drug effects. Non-steroid anti-inflammatory drugs (NSAIDs) are widely prescribed drugs that induce the serious side effect of gastric mucosal ulceration. Biomarkers for these side effects have not been identified and ulcers are now only detectable by endoscopy. We previously identified five metabolites as biomarker candidates for N...

A review of 82 (68 male) Kelantanese patients with non-alcoholic cirrhosis who underwent gastroduodenal endoscopy revealed duodenal and gastric ulcers in 4.9% and 7.3% of patients respectively. Comparing with prevalence rates of peptic ulcer disease reported in the literature, there was no evidence to suggest that duodenal ulcers occur more frequently in patients with non-alcoholic cirrhosis. T...

BACKGROUND Prostaglandin endoperoxide synthase/cyclooxygenase (COX) is the key enzyme in gastric mucosal protection and repair but its cellular localisation in the human stomach is still unclear. AIMS To investigate immunohistochemically the cellular distribution of COX-1 and COX-2 proteins in the human stomach with or without gastritis or ulceration. PATIENTS AND METHODS Tissues were obtai...

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...
