RESUMEN
Objective To explore therapeutic effects and mechanisms of radical scavenger edaravone on experimental cerebral hemorrhage.Methods Two hundred-forty male SD rats were divided randomly into four groups:control group,cerebral hemorrhage group,edaravone treatment group before operation (A) and edaravone treatment group after operation (B).Experimental cerebral hemorrhage model was made according to the method reported by Rosenberg.Water quantity contained in brain and nervous missing sign were observed,meanwhile the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in brain tissue were measured.Results Compared with cerebral hemorrhage group,nervous missing sign and water quantity contained in brain obviously changed in edaravone treatment group (P
