Abstract: | The effect of high dose of gamma radiation (200 Gy) on energy of rat liver mitochondria was studied. 1 hour after irradiation state 3 (V3) increased by 32 +/- 7%, state 4 (V4)- by 25 +/- 8%, the rate of ATP synthesis by 52 +/- 11%. 48 hours after irradiation these parameters decreased to control levels inspite of accumulation of lipid peroxidation products. |
