Results (1) Compared with that of 4-Retro-decoction group and heart failure control group, the activity of Na〓-K〓-ATPase in low- and middle- dosage ginger group showed to be decreased with statistically significant difference. P＜0.05.(2) The activity of Ca〓-ATPase and Mg〓-ATPase in the lower- and middle-dosage ginger group were not statistically different from that of 4-Retro-decoction group and control group, but the activity of Ca〓-ATPase showed an ascending tendency in low-dosage ginger group.

结果 (1)低、中剂量干姜组的Na〓-K〓ATP酶活性明显偏低，与四逆汤组和心衰组比较，差别均具有显著性，P＜0.05；(2)低、中剂量干姜组的Ca〓-ATP酶和Mg〓-ATP酶活性与四逆汤组和心衰对照组比较，无统计学意义，但低剂量干姜组的Ca〓-ATP酶与其它三组相比有升高趋势。

Objective To investigate the difference between the effects of Ginger Extract and4-Retro-deˉcoctionon cardiac systolic/diastolic function of rabbit with heart failure.Methods 40pure-breed New-Zealand rabbits were randomly divided into4groups:low（0.028mL/kg）,middle（0.056mL/kg）,high（0.112mL/kg）dosage ginger group and4-Retro-decoction group.The heart failure model of rabbit was established by intravenous administration of20g/L pentobarbital sodium at a certain rate.Oral tube perfusion of ginger extract and4-Retro-decoction were administrated after the establishment of the model.Their hemodynamic changes were detected before and after the model establishment,and at5,10,15,20,30,45,60,90,120,150minutes respectively after the ginger administration by a RM-6004-graph physiological monitor.
