Abstract

Free-radical processes upon long-term omeprazole-induced gastric hypochlorhydria in the rat liver were researched. Intensification of oxidative processes in the liver tissue upon gastric hypoacid state was established: overproduction of superoxide anion, hydrogen peroxide, the quantitative changes of lipid functional groups, increased level of lipid peroxidation products, and augmentation of xanthine oxidase activity. The expression of Tgfb1 gene increased, while the expression of Hgf gene was not detected upon long-term suppression of gastric acid secretion of hydrochloric acid by omeprazole that indicated possible development of liver fibrosis. Abovementioned parameters were only partially restored to control values in the case of simultaneous administration of multiprobiotic "Symbiter acidophilic" concentrated with omeprazole, thus indicating the ability of this preparation to counteract the development of oxidative damages in liver tissues upon long-term gastric hypoacidic conditions.
