Abstract
Objective To investigate the effect of cinepazide maleate preconditioning on rat models of cerebral ischemia,and explore its neuroprotective function.Methods SD rats were randomly divided into cinepazide maleate preconditioning group(treatment-operation group),normal saline preconditioning group(control-operation group) and cinepazide maleate preconditioning without operation group(treatment-non-operation group).After preconditioning for 5 d,ischemic rat models were established by the modified suture method of left middle cerebral artery occlusion in treatment-operation group and control-operation group.One day,3 d and 7 d after operation,the changes of behaviors and brain tissues of rats in each group were observed.In treatment-operation group and control-operation group,the hemiplegia status was scored,areas of cerebral ischemia were calculated with TTC staining of brain slices,and the severity of cerebral ischemia was compared.Results One day and 3 d after operation,there was no significant difference in the hemiplegia score and area of cerebral ischemia between treatment-operation group and control-operation group(P0.05).The hemiplegia score was significantly lower,and the area of cerebral ischemia was significantly smaller in treatment-operation group than those in control-operation group 7 d after operation(P0.05).No behavior changes and ischemic area of brain slices was observed in treatment-non-operation group.Conclusion Cinepazide maleate may have a neuroprotective function in cerebral ischemia.
