[Evaluation of cell membrane permeability for Ca2+ and adenylate cyclase in sheep peripheral blood cells, exposed to low doses of radiation]. / Otsenka pronitsaemosti plazmaticheskoi membrany dlia Ca2+ i aktivnosti adenilattsiklazy v kletkakh perifericheskoi krovi ovets, obluchennykh v malykh dozakh.

Chronic irradiation of sheep with doses of 2.6 and 12.9 mC.kg was characterized by the modification of the adenylatecyclase activity and Ca2+ permeability of plasma membrane in cells of the peripheric blood, with no changes in the clinical and hematological indicators. The observed effects are assumed to result from structural and dynamic variations in the lipids of membranes.
