Abstract:
ObjectiveTo study neural protective effect of combined medication with nimodipine and mannitol on injury of cerebral ischemia-reperfusion for screening the better medication method in acute cerebral ischemia-reperfusion. MethodsA model of cerebral ischemia-reperfusion was performed by clipping bilateral common carotid artery of rats with vago- and releasing them 3 hours later. 40 Wistar female rats within 1 month were divided into 5 groups randomly with 8 rats each: model group (no use of medicine), nimodipine group(0.2mg/kg), mannitol group(0.5g/kg), nimodipine and mannitol group, sham-operated group (no use of medicine and no clipping process). The changes of SOD and MDA in brain tissue were measured 24 hours after cerebral ischmic reperfusion in all groups. At the same time pathologic study was performed to compare the different groups.ResultsThere were significant differences between nimodipine and mannitol group and other groups in changes of SOD, MDA and pathological changes(P<0.01). Conclusions Combined medication with nimodipine and mannitol is the better way to protect brain tissue from acute cerebral ischemia-reperfusion than other way in present experiment, by synergistic action.
