[Comparative study of chemiluminescence and resistance of serum and its components after radiation exposure].

Kinetics of spontaneous chemiluminescence (CL) and electrochemiluminescence (ECL) and resistance of blood serum and its protein, lipid and carbohydrate components under the effect of X-rays (3 to 1622 Gy) and the indirect effect of radiation initiated by the addition of hydrogen peroxide (1.5 X 10(-5)-1.5%) was studied to estimate the contribution of each of the serum components to cumulative changes in the kinetics of free radical oxidation initiated by the effect of radiation. There was a parametric dependence between the absorbed dose, the rate of ECL and the resistance of blood serum and its components. As the absorbed dose or hydrogen peroxide concentration increased ECL contribution to the cumulative luminescence signal regularly decreased. Changes in CL and ECL of blood serum induced by ionizing radiation and H2O2 were qualitatively similar. The kinetics of free radical oxidation of blood serum initiated by irradiation was determined integrally (according to CL and ECL parameters) by a complex of changes in its components.
