[The role of ligands in the effect of exposure to ionizing radiation on Ca2(+)-ATPase and Mg2(+)-ATPase].
The change of Ca(2+)-ATPase and Mg(2+)-ATPase activity in plasma membranes of thymocytes irradiated with doses of 10(2), 10(3) and 10(4) Gy in the presence of Ca2+, Mg2+ and ATP was studied. Stabilizing effect of Ca2+ and Mg2+ on Ca(2+)-ATPase and ATP on Mg(2+)-ATPase under irradiation was established.
