[Metabolic disorder of various protein fractions in the thymocytes of irradiated rats (an electrophoretic analysis and proteins interacting with DNA].

Using PAAG-electrophoresis and subsequent fluorography no essential disorders were detected in the biosynthesis of some protein fractions of the cytoplasm and nuclear sap of thymocytes during the first 2 h following irradiation of rats with a dose of 8 Gy. There was a decrease, progressing in time, in the rate of the synthesis of certain polypeptides. Inhibition of the biosynthesis of the proteins reacting with DNA was demonstrated by the chromatography, on DNA-containing columns, of labeled proteins of different fractions. The most pronounced changes were observed in the group of firmly bound proteins.
