[Effect of ionizing radiation on ATPase activity of thymocyte plasma membranes]

Thymocytes were irradiated by the doses of 4-1000 Gr. Activity of Ca(2+)-ATPase and Mg(2+)-ATP-ase, and lipid peroxidation were determined. It is supposed that changes in Ca(2+)-ATPase activity is connected with the adsorption of irradiation energy, while changes in Mg(2+)-ATPase activity are determined by effect of lipid peroxidation.
