Abstract
We examined the change of regional cerebral blood flow (rCBF) and loca l cerebral glucose utilization (LCGU) in the middle cerebral artery (M CA) occlusion or recirculation model of rats, and tested anti-ischemic effects of a free radical scavenger, 3-methyl-1-phenyl-pyrazolon-5-on e (MCl-186). A remarkable increase in LCGU was observed in the cortex supplied by the anterior cerebral artery after recirculation. This hyp ermetabolism of glucose was at least partly caused by the postischemic oxidative injury, since MCl-186 ameliorated the high LCGU in this are a. These results suggested the usefulness of this type of free radical scavenger for inhibiting the postischemic injury.
