摘　　要：目的探讨依达拉奉对大鼠脑出血后脑水肿及脑组织氧化损害的影响。方法选取健康雄性清洁的SD大鼠150只,随机分为假手术组、对照组、治疗组,每组50只,分别于术后0.5、1、2、3、4 d 5个时间点对每组中不同10只进行观察。采用立体定向自体血注入法制作大鼠脑出血模型,检测3组并比较各时间点血肿周围脑组织含水量变化、丙二醛（MDA）含量变化及超氧化物歧化酶活力情况。结果假手术组和治疗组术后1~4 d各时间点血肿周围脑组织含水量均显著低于对照组（P〈0.05）;对照组在术后2d脑水肿达到最高值;假手术组、治疗组术后0.5~4 d各时间点血肿周围脑组织MDA含量均显著低于对照组（P〈0.05）;假手术组、治疗组术后0.5~4 d各时间点血肿周围脑组织SOD活力均显著高于对照组（P〈0.05）。结论依达拉奉能明显改善脑出血大鼠血肿周围脑组织水肿,减轻脑出血大鼠脑组织氧化损害。Objective To discusse the effect of edaravone for brain tissue oxidative damage after cerebral hemorrhage through observing the hemorrhage rats back edema and the change of lipid peroxidation. Methods 150 healthy and clean male SD rats,were randomly divided to sham operation group,control group,treatment group,50 cases in each group,each group choose five time points,post operative 0. 5 day,1 day,2 days,3 days,4 days,observed different 10 rats at each time point. The intracerebral hemorrhage model was made by using the method of stereotactic autologous blood injection. The changes of water content,the content of MDA and the activity of superoxide dismutase were monitored in three groups at different time points. Results Surrounding the hematoma in the brain tissue around the hematoma after intracerebral hemorrhage in sham operation group,treatment group of postoperative day 1-4 days each time hematoma surrounding brain tissue water content was significantly lower than that in control group（ p〈0. 05）; Control group after 2 days of cerebral edema and reached the highest value; Sham operation group and treatment group of postoperative half of the day to 4 days each time the content of MDA were significantly lower than in control group（ p〈0. 05）; Sham operation group and treatment group postoperative half of the day to 4 days each time the brain tissue SOD activity was significantly higher than control group（ p〈0. 05）. Conclusion The effect is obvious that edaravone for cerebral hemorrhage rats brain tissue around hematoma edema,reduce cerebral hemorrhage rat tissue oxidative damage.
