[Effect of artificial gravitational force in space flight on the concentration of water soluble proteins in nerve tissue structures].
The content of water-soluble proteins in the grey and white matter of the spinal cord, spinal ganglia, and the sensory-motor area of the large hemispheres of the brain of rats after a 18.5-day space flight was measured. The content of water-soluble proteins in the grey and white matter of the spinal cord and spinal ganglia of rats exposed to weightlessness showed a significant decrease 4.5--9.5 hours postflight. The water-soluble protein content in the white matter of the spinal cord diminished in rats exposed to artificial gravity inflight. The water-soluble proteins content in the grey matter of the spinal cord of rats exposed to weightlessness increased significantly 25 days postflight. The content of water-soluble proteins in the grey matter of the cortex of the sensory-motor area of the large hemispheres of the brain of rats exposed to weightlessness and artificial gravity remained unchanged in comparison with the vivarium controls both 4.5--9.5 hours and 25 days postflight.
