Changes of TNF-alpha and malondialdehyde content in brain tissue and therapeutic effect of edaravone on rats after intracerebral hemorrhage / 第三军医大学学报

ABSTRACT

Objective To observe the protective effect of edaraven on brain tissue and the therapeutic mechanism in rats following intracerebral hemorrhage(ICH).Methods In this series,96 Sprague-Dawley rats were divided into three groups at random(n=32 in each group):sham-operative group,ICH model group and edaraven therapy group.ICH model was induced by infusion of autologous whole blood into the caudate-putamen.Rats in sham-operative group were treated the same as above,but no blood injected.Rats in edaraven therapy group were treated with edaraven(3 mg/kg)by peritoneal injection 30 min before operation and once per 12 hours after operation.These rats were killed at 6,24,72,and 168 h after neurologic impairment test with Longa criteria.Brain water content was measured by dry-wet weight method.Malondialdehyde and TNF-alpha in the vicinity of the hematoma were measured by thio-barbituric acid method and ELISA respectively.Results Compared with sham operative group,neurologic impairment score,brain water content,malondialdehyde and TNF-alpha in brain tissues were obviously higher in ICH model group(P
