[The comparative characteristics of the hemodynamic and biochemical indices of the postischemic period in relation to the regimens of brain autohemoperfusion].

In anesthetized cats, comparative characteristics of hemodynamics and biochemical indications of postischemic period in respect to autohemoperfusion with stable blood volume and perfusion pressure, were determined. Cerebral ischemia was caused by the 15-min stop of the perfusing pump or flowmeter and a decrease of systemic arterial blood pressure to 40 ml Hg. In the autohemoperfusion of brain vessels in stable volume or stable arterial pressure, a phasic postischemic phenomenon becomes obvious. The regularity of modifications of the glucose and oxygen consumption by the brain, concentration of lactate and pyruvate under different conditions of autohemoperfusion, was found.
