[Epidemiology of stomach cancer in North Caucasus].

The study of gastric cancer epidemiology in the North Caucasus has indicated that this disease shows a definite regularity in its spread--sharply pronounced regionality, conditioned by natural (geochemical and hydrochemical) local conditions. Geohydrochemical conditions of the region determine differences in the gastric cancer incidence among Russian population living in different geographical zones. Fluctuations in the incidence of gastric cancer morbidity between males and females are mostly conditioned by different habits of nutrition and alcohol consumption.

[Effect of psychotropic and anticonvulsive preparations on transport ATPase in the renal tubules of the guinea pig].

The effect of 4 groups of medicamentous agents, viz. neoruleptics, tricyclic antidepressants, somnifacients and antiepileptics - on the activity of the transport ATPase and p-nitrophenylphosphatase from the renal tubules of the guinea pig was studied. Used in high concentrations neuroleptics suppress almost completely the activity of the enzyme, but in small doses influence but little that of the p-nitrophenylphosphatase.
