Abstract

The intensity of free-radical processes upon long-term omeprazole-induced hypoacidity in the rat pancreas was investigated. Significant violation of oxidative-antioxidative balance in pancreatic tissue upon gastric hypochlorhydria was established: overproduction of superoxide anion, quantitative changes of lipid functional groups, increased level of lipid peroxidation products, augmentation of xanthine oxidase, superoxide dismutase and glutathione transferase activity, as well as depletion of catalase, glutathione peroxidase activity and reduced glutathione content. The inflected expression of Cckbr gene in the rat pancreas upon these conditions was also observed, thus suggesting an increased risk of pathological changes development in the gland. Abovementioned parameters were only partially restored to control values in the case of simultaneous administration of multiprobiotic "Symbiter" with omeprazole, thus indicating the ability of this preparation to efficiently counteract the development of oxidative damages in pancreatic tissues upon long-term hypoacidic conditions.
