Biophysical studies of irradiated thymocytes. 2

In order to study postirradiation changes in thymus lymphocyte membrane, a complex of biophysical analytical methods was used: chemiluminescence, fluorescence of nonpolar probe of pyrene (lipid bilayer) and ultraviolet fluorescence and phosphorescence (membrane proteins). Increase in strength of microenvironment of membrane proteins 1 hour after irradiation, as well as reduction of microviscosity and amplification of processes of peroxide oxidation of lipids belonging to the membrane lipid bilayer in the interval of 2-3 hours of X-ray irradiation at a dose of 4 Gy are shown.
