Abstract

The effect of a course of cerebrocrast, a 1,4-dihydropyridine derivative, on brain edema (as shown by impedometry) and cerebral tissue microvascularization in ischemia caused by ligation of the left common carotid artery and 50% restriction of the bloodflow in the right common carotid artery is studied in Wistar rats. Cerebrocrast is found to appreciably limit the development of brain tissue edema and to improve the status of microvessels by reducing the number of sharply constricted nonfunctioning capillaries and increasing the number of capillaries of 4 μ and more in diameter. Pronounced antioxidative effects of cerebrocrast in transitory cerebral ischemia are demonstrated.
