[The effect of the repeated irradiation of rats on the Ca2(+)- and Mg2(+)-ATPase activity of thymocyte plasma membranes].
Rats were daily irradiated at doses 0.5 Gy in period of two weeks. The activity of Ca(2+)-ATPase, Mg(2+)-ATPase and the extent of lipid peroxidation in thymus were determined. The peculiarity of changing of enzymes activity demonstrates the dependence of Mg(2+)-ATPase on lipid peroxidation.
