Chinese Journal of Rehabilitation Theory and Practice 2004;10(12):726-728
ObjectiveTo investigate the effect of hyperbric oxygen (HBO) on infarct volume and relevant mechanism after permanent focal cerebral ischemia in adult rats.MethodsRat model of focal cerebral ischemia induced by intraluminal filament occlusion of middle cerebral artery (MCA) was used. HBO(2.0 ATA) was applied to HBO group. Infarct volume, matrix metalloproteinase 2 (MMP-2) and MMP-9 were detected at 6h, 24h, 48h, 72h,120h and 10d after ischemia.ResultsThe infarct volume obviously decreased at 120h and 10d and expression of MMP-9 lowered at 48—120h in HBO groups. There was no significant change in MMP-2.Conclusion HBO can reduce infarct volume after cerebral ischemia, which may be related to downregulation of MMP-9 levels.

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.
