ABSTRACT
@#ObjectiveTo observe the effect of Batroxobin and Urokinase on brain of diabetic rats following focal cerebral ischemia and reperfusion injury. To investigate the preventive mechanism of Batroxobin following focal cerebral ischemia and reperfusion injury in diabetic rats after thrombolysis therapy.MethodsDiabetic rat was induced by administrating streptozotocin intraperitoneally. Rat model of focal cerebral ischemia and reperfusion injury induced by intraluminal filament occlusion of middle cerebral artery(MCA) that removed 2h later was used. Batroxobin and Urokinase were administrated intravenously in different groups. Infarct volume,cerebral hemorrhage and matrix metalloproteinase (MMP)-2,MMP-9 were detected at 2h,24h,48h after ischemia and reperfusion injury.ResultsThe significant decrease of infarct volume were observed in Batroxobin and Urokinase groups. There were 5 rats observed cerebral hemorrhage in Urokinase group and no cerebral hemorrhage in Batroxobin group. The number of MMP-2 and MMP-9 positive cells in Batroxobin and Batroxobin Urokinase groups decreased compared with saline and Urokinase groups. ConclusionBatroxobin can decrease the infarct volume significantly without the complication of cerebral hemorrhage after ischemia and reperfusion injury in diabetic rats, which maybe relate to down regulation of the expression of MMP-2 and MMP-9.
