Z DEVD AMC substrate cleavage and TBARS methods were used to measure the activity of caspase 3 and the content of lipid peroxide in right ventricular myocardium,respectively.

• 分别用Z DEVD AMC底物降解法和TBARS方法测定右心室caspase 3活性和MDA含量。 结果 CHD病人右心室心肌细胞凋亡数、caspase 3活性和MDA含量均明显高于ASD病人 (分别P =0 0 2 6,0 0 13和 0 0 0 2 ) ;
