[Effect of prolonged hypokinesia on PO2 dynamics in the brain tissues of rats in orthostatic and antiorthostatic tests].
Variations of PO2 in rat brain tissues were assessed polarographically during orthostatic tests. Prolonged hypokinesia (up to 100 days) did not induce significant changes of PO2 in rats at rest. During orthostatic tests PO2 of control rats changed insignificantly. Prolonged hypokinesia led to more marked changes of PO2 in rats exposed to an orthostatic test. Changes in the cerebral oxygenation of hypokinetic rats were varying and inadequate, differing appreciably from the cerebral oxygenation of control animals.
