[Neurochemical characteristics of rats during flight on the Kosmos-782 artificial satellite and after returning to earth].
The brain of rats flown aboard the biosatellite Cosmos-782 was sampled immediately postflight and taken under neurochemical study. It was shown cytospectrophotometrically that the absolute content of RNA decreased by 20% in the cytoplasm of cerebellar Purkinje cells and remained unaltered in glial cells-satellites, and that the protein content did not change. In the frontal cortex (homogenates) the concentration of sulfhydryl groups decreased by 26%, activity of nonspecific cholinesterase by 33%. The activity of the latter in the cerebellum also diminished.
