On wistar rats expression of P-glycoprotein in the brain after unilateral occlusion-reperfusion of the common carotid artery was studied. Correlation between the expression of the transporter and redox status of the brain cerebral cortex was assessed. Occlusion was simulated under ether anesthesia by common carotid artery clamping using vascular clamp for 180 minutes followed by recanalization. Samples of cerebral cortex were taken after 60 min, 4 h, 24 h, 5 days and 14 days after reperfusion and subjected to standard immunohistochemical processing, as well as evaluating the redox status. It was revealed that the 180-minute occlusion of unilateral common carotid artery followed by reperfusion causes a decrease in the expression of P-glycoprotein after 60 min and 4 hours after reperfusion by 52,5% и 63,1% (p<0,05) respectively. P-glycoprotein expression is conversely related with the level of TBA-reactive species.
