[The effect of millimeter-range electromagnetic and of ionizing radiation on the body and thymocytes of mice and rats].
Radiomodifying effects of ultra-high frequency electromagnetic radiation (UHFER) were studied using laboratory mice and rats, as well as irradiated rat thymocytes in vitro. The resistance of mice to lethal effects of X irradiation was increased by preceding UHF treatment at 7.1 mm wavelength. By means of electron paramagnetic spin resonance, it was revealed that UHFER induced a sufficient decrease in free radicals and iron-binding proteins in rat thymus following UHF irradiation in vivo. The UHFER of rat thymocytes caused similar changes in Acridine orange binding to cellular DNA, light scatter parameters of thymocytes, their own UV fluorescence and partition in two phase systems as X irradiation. Possible mechanisms of these effects are discussed.
