Methods:

The experimental rat cardiac and lung injury was reproduced by acute cardiac infraction ligating left coronary artery for 4 weeks.Cardiac function were assayed by hemodynamics,heart index and lung index were detected by weighting,pathologic change was checked out by histophathology,and cardiac infarction size was assayed by image analysis system.

Results:

After operation 4 weeks,cardiac function was disturbed according to the results of hemodynamics.Cardiac and lung index,and cardiac infarction size was significantly increased in model group.Results of histopathology indicated that cardiac myocyte decrease,cardiac fibrosis functional disorder of the heart,increase of heart index and lun index,inflammatory cell infiltration,and pulmonary congestion and edema and so on indicated the model was succeed.Continued administration of n-butanol extract from RP for 4 weeks can remarkable ameliorate cardiac function,decrease the cardiac and lung index,and attenuate the heart failure pathological change.
