[Photoreactivation of Ca2+-ATPase and Mg2+-ATPase after exposure to ionizing radiation].
Plasma membranes of thymocytes in doses 10(2), 10(3) and 10(4) Gr were irradiated and subsequently illuminated by lambda = 445,5 nm or lambda = 518 nm light. Then the activity of Ca(2+)-ATPase and Mg(2+)-ATPase was determined. The photomodulation of the electron shell of calcium and magnesium atoms is a factor decreasing the effect of radiation on Ca(2+)-ATPase or Mg(2+)-ATPase.
