title: [Immunological reactivity of rats exposed on the Kosmos-605 and 690 biosatellites].
abstract: Immunological reactivity of rats flown aboard the biosatellites Cosmos-605 and Cosmos-690 was compared with respect to the complementary activity of serum and frequency antibodies to sheep red blood cells. Cosmos-605 rats showed changes that rapidly returned to the normal whereas Cosmos-690 rats irradiated inflight with a dose of 800 rad exhibited significant and stable changes in immunological reactivity. Those latter seemed to be associated with the combined effect of ionizing radiation and other space flight factors.
