  • Title: [Recovery of hemopoiesis in rats irradiated in space].
    Author: Kalandarova MP, Rodina GP, Smirnova TM.
    Journal: Kosm Biol Aviakosm Med; 1978; 12(5):15-20. PubMed ID: 692063.
    Abstract:
    Repair regeneration of hemopoiesis of rats exposed to gamma irradiation with doses of 220 and 800 rad in space flight was studied. There was an insignificant difference in the dynamics of the most blood and bone marrow formed elements. It can be concluded that myelopoiesis in space flight was more active than on the Earth. Irradiation of animals with 800 rad aboard the biosatellite Cosmos-690 induced more pronounced hemopoietic changes than the ground-based exposure (on the 1st-2nd post-flight day the count of myelokaryocytes and lymphocytes in bone marrow decreased). The Most hematological parameters returned to the norm on the 36-37th post-irradiation day (on the 26th postflight day).
