title: [DNA content in the organs of animals in space flight on the Kosmos-690 satellite].
abstract: The DNA content in the liver, spleen and bone marrow of white rats exposed to a prolonged gamma-irradiation at a dose of 220 and 800 rad on the 10th day of the 20.5-day space flight and the ground-based synchronous experiment was measured. Space flight factors produced a modifying effect on the postradiation changes in the DNA content. This modifying influence was detected in all organs tested, although in a different degree, and involved an enhancement of the radiation effect which was associated with retardation of postradiation regenerative processes.
