西洋参茎叶皂甙对大鼠培养心肌细胞氧化损伤的保护作用

Protective Effects of PQS on Oxidative Damage of Cultured Rat Cardiac Cells

黄嘌呤-黄嘌呤氧化酶可引起大鼠培养心肌细胞电参数变小、心肌细胞起搏比例减少及心肌细胞超微结构破坏。西洋参茎叶皂甙可使上述指标明显改善,说明其有抗氧化损伤作用。

When cultured cardiac cells of rats were exposed to X-XOD containing medium, the absolute values of electronic parameters were decreased the percentange of beating clusters reduced and the microscopic structure destroyed. PQS significantly converted all the indices, which shows that PQS can protect the cells from oxidative damage.
