Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.

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.
