[The effect of low doses of long-term internal irradiation on the ultrastructure and intensity of lipid peroxidation in rat brain and blood].
Rats were administered with the mixture of 137Cs and 85Sr for 30, 56 and 90 days. Dynamic of ultrastructural changes of lipid peroxidation has been studied in cerebrum and blood. Maximum biochemical changes have been detected after radionuclide administration for 30 days (increase in spontaneous chemiluminescence intensity and quantity of TBA-active products). Under further administration lipid peroxidation parameters as well as radionuclide content in blood and organs were sufficiently stable, while ultrastructural changes were in progress during the influence.
