Methods: Twenty-four rabbits were randomly divided into three groups:① the control group(group C, n=8): received sternotomy only and no ischemia;② the ischemia/reperfusion group(group I/R, n=8): the left lungs of rabbits were rendered ischemia by ligating the left pulmonary hili for 60 minutes followed by 60 minutes reperfusion;③ the edaravone group(group E, n=8): the left lungs were rendered ischemia for 60 minutes followed by 60 minutes reperfusion, and 10 mg/kg edaravone was administered intravenously 5 minutes prior to ischemia. Blood MDA and SOD were measured. Protein concentrations, WBC count, and PMN percentage in broncho-alveolar lavage fluid were determined. Samples of left lung tissue were sent for determining the left lung dry-to-wet weight ratio and evaluating the pathologic changes.

采用兔肺原位热缺血再灌注损伤模型进行研究。24只大白兔随机分为三组：①对照组(C组， n=8)，开胸后不阻断肺门，静脉缓慢推注生理盐水5ml/kg；②缺血再灌注组(I/R组， n=8)，左肺接受60min的缺血，然后接受60min再灌注，于缺血前5min静脉缓慢推注生理盐水5ml/kg；③依达拉奉干预组(E组， n=8)，于缺血前5min静脉缓慢推注依达拉奉10mg/kg（5ml/kg），左肺接受60min的缺血，然后接受60min再灌注。120min实验结束时，留取各组动物血液标本，测定血浆丙二醛含量及超氧化物歧化酶活性；收集支气管肺泡灌洗液，检测支气管肺泡灌洗液中白细胞计数、中性粒细胞百分比及肺通透性指数；留取肺组织标本，测定肺组织湿、干重量，计算干／湿重比及行肺组织病理检查。
