[The antioxidative activity of homogenates and lipids obtained from intact and ischemic organs in rats].

The antioxidative activity of homogenates and lipids isolated from the brain, heart and liver was studied. The model of thermal autoxidation of linetolum in the presence of specimens studied was used. The antioxidative activity of lipids from the heart is higher than that of lipids from the brain.

[Effect of supposed radioprotectors on oxidation-reduction of vitamin E in the tissues of irradiated rats].

In experiments with mature Wistar male rats under irradiation by dose of 5 Gy the effect of emoxypine, citomedine and echinacea purpurea on the content of liposoluble vitamin A, carotene, vitamin E and its metabolites (quinone and oxidized tocopherol) in blood plasma, spleen, liver and testes was studied. It was shown the drugs under study mobilized the internal reserves of these vitamins and promoted effective functioning of vitamin E redox system. Mechanisms of their action are different.
