title: [Biochemical study of erythroid hematopoietic reserves during prolonged irradiation].
abstract: A study was made of the effect of hydrochloride phenylhydrazine on the content and rate of biosynthesis of nucleic acids in the bone marrow and spleen of rats exposed to long-term fractionated gamma-irradiation (0.5 Gy, 6 times a week). The stimulatory effect of phenylhydrazine on the rate of the nucleic acid biosynthesis was shown to decrease in the tissues under study with dose cumulation from 2.5 to 25 Gy.
