[Posthypoxic changes in the cerebral cortex of dogs in the late recovery period after 4-hour hypovolemic hypotension].
On the 14th-21st day of the restorative period after four-hour hypovolemic hypotension the level of total RNA decreased in the tissue of the gray matter of the brain by 20.9%, and of DNA-by 13%. In the postmitochondrial supernatant the concentration of prealbumins was reduced by 26.5%, alpha-globulins--19.2%, gamma-globulins--by 59.8%; the concentration of albumins and beta-globulins was increased by 12.6% and 50.0%, respectively. The activity of acid cathepsins  rose by 50%, and of acid phosphatase--by 44%. The activity of total lactic dehydrogenase (LDH) and glutamic dehydrogenase failed to differ essentially from the control level. However, LDH isoenzyme spectrum changes towards the reduction of LDH3+4+5 from 31.9 to 14.2%. Analysis of densitograms of electrophoresis in polyacrylamide gel showed physico-chemical changes in the protein molecules similar in nature to the denaturation phenomenon. The Purkinje's cell count decreased in the cerebellum by 41.3% in comparison with control.
