Abstract

By means of an autoradiographic technique employing 14C-2-deoxyglucose, abnormalities of local brain glucose utilization were studied 90 min following occlusion of the left middle cerebral and common carotid arteries in a series of pentobarbital-anesthetized cats. In animals with vascular occlusion, a zone of greatly suppressed glucose utilization occupied the caudate nucleus of the ischemic hemisphere, with variable extension, and was surrounded by a narrow rim of increased local brain glucose utilization, suggesting the occurrence of enhanced anaerobic glycolysis in the latter zones. The cerebral cortex, which was less constantly affected, showed alternating regions of increased and decreased glucose utilization. Quantitation of local brain glucose utilization values from the contralateral nonischemic hemisphere revealed a mild suppression of cortical glucose utilization relative to the control animals. This may be the metabolic equivalent of diaschisis.
