Abstract

The reversible changes of cerebral cortex vessels prevail in cerebrovascular ischemia caused by unilateral ligation of the common carotid artery in rats. In bilateral ligation of the common carotid arteries, vertebral arteries, stenosis of ascending aorta the dystrophic vascular changes are manifested significantly. In postepileptic period in the presence of cerebrovascular disorders the dystrophic changes of cerebral cortex vessels prevail. In audiogenic epilepsies in the presence of renal hypertension and alimentary atherosclerosis the dystrophic changes of the vessels increase.
