title: [Regeneration of nucleic acid metabolism in rat bone marrow and spleen at prolonged intervals after lengthy fractionated irradiation].
abstract: A study was made of the content and rate of biosynthesis of nucleic acids in the bone marrow and spleen, the mitotic activity of splenocytes and the lienogram of rats during a year after the end of fractionated irradiation with cumulative doses of 9.7 and 19.4 Gy. It was shown that the completeness of restoration of the parameters changed by irradiation depended upon radiation dose received by the animals. Inhibition of proliferative processes in the bone marrow was noted a year after irradiation with a dose of 19.4 Gy.
