[Lipid peroxidation and ATPase activity in synaptosomal and mitochondrial fractions of the brain in hypoxia].
Acute hypoxia was accompanied by intensification of lipid peroxidation in synaptosomal and mitochondrial rat brain fractions as well as by inhibition of Na+, K+- and Mg2+-ATPases. Preadministration of antioxidants vitamin E and ionol into animals prevented distinctly the increase in lipid peroxidation rate, while the ATPases activity was unaltered. Inhibition of the ATPases may be considered as a result of impairing effect of the lipid peroxidation products, which appears to be of importance for structure-functional deteriorations of the nervous system in hypoxia.
