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.
