Abstract:
AIM:To investigate the protective effect of a new type nerves protectant TQ0701-2,as the derivate of edaravone free radical scavenger,on cerebral ischemia reperfusion injury rat.METHODS:120 male SD rats were randomly divided into sham group,model group,edaravone group(3.0 mg/kg)and TQ0701-2 high-dose group(6.0 mg/kg),middle-dose(3.0 mg/kg)and low-dose group(1.5 mg/kg).Animals in the latter five groups were subjected to transient focal ischemia by the middle cerebral artery occlusion(MCAO)for 2 h before reperfusion,while the sham group wasn't ischemic.The rats were injected with edaravone or TQ0701-2 30 min before ischemic and 0 min,2 h after reperfusion in edaravone and TQ0701-2 groups,sham group and model group were treated with normal saline as well.After 24 h of reperfusion,the infarct ratio,neurological and histological deficient and the changes of pathohistology were evaluated.RESULTS:The infarct ratios and neurological deficit scores in the model group were increased(P
