[Correlation of chemiluminescent parameters of blood in non-irradiated animals with their survival after irradiation].

Blood chemiluminescence is a reflection of the free radical oxidation process in every organism. The changes of its intensity, as a consequence of changes in the rate of this process, are connected, in its turn, with the changes, in the functional state of the organism. It is supposed that the differences in the radiosensitivity depend on the conditions in which free radical oxidation processes take place. Therefore, the indices of blood chemiluminescence of intact rats have been studied. The aim of the investigation is to find the correlations between these indices and the survival of animals irradiated with gamma-quantas in doses of 3.5, 7.0 and 9.0 Gr. It is established that the coefficients of the reaction rate (k1, k2 and k3) most reliably correlate with survival, whereas no correlation is observed between the other indices of chemiluminescence and survival.
