Ischemia Reperfusion Injury after Gradual versus Rapid Flow Restoration for Middle Cerebral Artery Occlusion Rats.

ABSTRACT: Ischemia-reperfusion injury (IRI) is an important cause of adverse prognosis after recanalization in patients with acute occlusion of major intracranial artery (AOMIA). Here, we provided data indicating that gradual flow restoration (GFR) would be superior to rapid flow restoration (RFR) in alleviating cerebral IRIs in middle cerebral artery occlusion (MCAO) rats. A total of 94 MCAO rats with 15, 30 and 60-minute occlusion were randomly assigned to receive either GFR or RFR intervention. There were significant differences between GFR and RFR group in mean neurological severity score (1.02 versus 1.28; p < 0.05), median infarct ratio (0.016 versus 0.12; p < 0.001), median neuronal apoptosis ratio (1.81 versus 14.46; p < 0.001), and mean histopathological abnormality score (0.92 versus 1.66;
