| Abstract: | As a result of total chronic gamma irradiation of mice (137Cs, 0.6 cGy/day, 9 days) the functioning of superoxide generation and utilisation systems in liver were disturbed. The regulatory links between the activities of superoxide dismutase and glutathione peroxidase are found to be maintained. Postradiation effects were more expressed for a total dose of 1.2 cGy than for a dose of 5.4 cGy, providing support for the hypothesis of delayed reparation as a reason of harmful action of low-dose irradiation. |
