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...

Gastric cancer (GC) is one of the most common malignant tumors and the Kazakh population in Xinjiang has been reported to be one of the highest incidence of GC in the world. Serum pepsinogen (PG) test provides a valuable method for detecting GC, but little study about the role of PG in Kazakh GC. Therefore, we aimed to investigate the role of PG in Kazakh GC and to elucidate the usefulness of t...

AIM to find out biomarker as diagnostic tool of H. pylori chronic gastritis. METHODS the design of present study was a diagnostic test and there were 104 subjects with H. pylori chronic gastritis who fulfilled the inclusion and exclusion criteria. The diagnosis of H. pylori chronic gastritis was based on histopathological examination and PCR with ureC primer of the gastric biopsy specimen. In...

Endoscopic findings of the background gastric mucosa are important in the Helicobacter pylori-seroprevalent population. It is strongly correlated not only with the risk of gastric cancer, but also with the excretion ability of gastric mucosa cells. In noninfected subjects, common endoscopic findings are regular arrangement of collecting venules, chronic superficial gastritis, and erosive gastri...
