Helicobacter pylori (H. pylori) infection prevails from 60-80% in patients with gastric ulcer and 90100% in those having duodenal ulcer. Patients with such type of chronic infection are at increased risk to develop peptic ulcers or gastric adenocarcinomas. The present work aims mainly to identify the pattern of chronic gastritis and potential effect of H. pylori infection using certain biomarke...
BACKGROUND AND AIMS Helicobacter pylori infection and gastric atrophy are both risk factors for gastric cancer. We aimed to elucidate the natural history of gastric cancer development according to H pylori infection and gastric atrophy status. SUBJECTS AND METHODS A total of 9293 participants in a mass health appraisal programme were candidates for inclusion in the present prospective cohort ...
To investigate the mechanism of the anti-peptic action of ecabet sodium (TA-2711) observed in pylorous-ligated rats, effects of this drug on the peptic activity of rat gastric juice, purified hog pepsin and pepsinogen were studied in vitro. After incubation with or without ecabet at acidic pH, the reaction mixture was centrifuged, and the peptic activity of the supernatant was measured. Ecabet ...
In children and adolescents from two areas of Costa Rica with contrasting gastric cancer risks, two factors suspected to be linked to the natural history of the disease were tested: serum antibodies to Helicobacter pylori and serum pepsinogen levels. One hundred fifty-five subjects from the high-risk area of Turrubares were compared to 127 from the low-risk area of Hojancha. No significant diff...
The gastric glands of Triturus carnifex (Amphibia, Caudata) have been examined by histochemical and immunohistochemical methods with particular regard to hydrochloric acid and pepsinogen secretion. Fundic glands consist of mucous neck cells, endocrine cells and oxynticopeptic cells producing both pepsinogen and hydrochloric acid. The neck cells showed an unexpected distribution pattern which wa...
