title: [Endothelial dysfunction in pathogenesis of duodenal ulcer].
abstract: It is shown that in patients with ulcer associated with Helicobacter pylori (HP) there is a close correlation between the severity of the lesion of gastroduodenal protective mucous barrier and that of endothelial dysfunction manifesting in elevated level of endothelin-1, serum levels of TBK-active products, inhibition of blood flow and narrowing of the celiac trunk. The correlation becomes stronger with expanding contamination of gastroduodenal mucosa with HP. Thus, HP may participate in breaking the protective mucous barrier in endothelial dysfunction.
