[Post-irradiation changes in the content of phospholipids and cyclic nucleotides in the mouse brain].

The effect of ionizing radiation (5, 20, 100, 200 and 400 Gy) on the content of phospholipids and cyclic nucleotides in the brain tissue has been studied in experiments on albino mice. During the development of evident behavioural disturbances in irradiated mice (2 h after irradiation with doses 100-400 Gy), significant changes were observed in the content of phosphatidylinositides and cyclic GMP. These changes may account for disturbances in the function of the central nervous system during cerebral forms of acute radiation injury.
