title: [Changes in the serum fraction composition of nucleic acids in radiation injuries. Alterations in an early period after gamma-irradiation of rats].
abstract: The content and fractional composition of nucleic acids of blood serum change after lethal (8 Gy) particularly superlethal (100 Gy) gamma-irradiation of rats. This concerns DNA the content of which increases by 7 times 5 h following 100 Gy irradiation. It has been shown by electrophoresis in 0.85% agarose that a heterogeneous DNA fraction with the molecular weight of (1-15) X 10(6) dalton increases. The analysis of the preparation in the polyacrylamide gel has revealed a DNA fraction that is not found in norm: the fraction possesses the electrophoretic mobility corresponding to that of nucleosome DNA.
