[Changes in the spinal cord of rats following the effects of single and multiple gravitational overloads of the "head-pelvis" direction].
The state of the neurons of the spinal cord and intervertebral ganglia in rats was studied morphologically after effects of single (12 units) and repeated for ten days with increase (from 3 to 12 units) gravitation stresses of the head-pelvis direction. Single and repeated gravitation stresses caused both hemodiscirculatory and considerable dystrophic alterations in the spinal cord. These processes were of undulatory character and were better pronounced during a month after single stresses. After repeated stresses they were less pronounced.
