[Structure-functional states of liver mitochondrial membranes of rats exposed to irradiation]. / Strukturno-funktsional'noe sostoianie mitokhondrial'nykh membran pecheni obluchennykh krys.

The effect of the low dose gamma-irradiation (270 cGy--one-fold; 90 cGy per day during 3 days) on oxidative phosphorylation, lipid peroxidation, microviscosity of the annular and free lipids membrane, and membrane protein structural state was studied. The post-radiation influence on membrane functional activity and structural state in accordance with the irradiation regimes was established.

[Effect of supposed radioprotectors on oxidation-reduction of vitamin E in the tissues of irradiated rats]. / Izuchenie vliianiia predpolagaemykh radioprotektorov na sostoianie redoks-sistemy vitamina E v tkaniakh obluchënnykh krys.

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. The drugs might be used as radioprotectors, but they exhaust the reserves of the liposoluble vitamins. Therefore they should be used in a combination with vitamin preparations.
