[Postradiation changes in the structural-functional properties of the thymocyte plasma membranes of irradiated rats]

Rats were exposed to radiation doses of 1.5, 4, and 7 Gy. Binding properties of 1-anilinonaphthalene-8-sulfonate, lipid viscosity, membrane protein structure, the activity of Ca(2+)-ATPhase and Mg(2+)-ATPhase in thymocyte plasma membranes were studied were investigated in health and on 1, 8, 15, 22, and 30 days. The character of post-radiation changes in the structure of thymocytes plasma membranes was determined.
