[Postradiation changes in Ca2+-ATPase and Mg2+-ATPase in thymocyte plasma membranes].
The rats were irradiated in the doses 1, 5, 4, 7 and 10 Gr and on the 1, 8, 15, 22 and 30 day after the irradiation activity of Ca(2+)-ATPase and Mg(2+)-ATPase and peroxidation lipids in the thymocytes was determined. It was found that postradiation changes in activity of Mg(2+)-ATPase were characterized by a higher sensitivity to the processes of lipids peroxidation as compared to Ca(2+)-ATPase.
