摘要: 目的 观察大鼠心肌缺血时心肌线粒体Na+、Ca2+、Mg2+含量、ATPase 活性的变化及油茶皂甙(SQS)对它们的影响。方法 以皮下多点注射异丙肾上腺素(ISO 4 mg · kg-1)诱导心肌缺血损伤为模型, 测定Na +、Ca2+、Mg2+含量及ATPase 活性。结果 心肌缺血时线粒体Mg2+含量明显减少, Na+、Ca2+含量显著增多;Na+-K+-ATPase 、Ca2+-Mg2+-ATPase 活性显著下降。SQS(0.2 mg ·kg-1, iv)能显著对抗缺血心肌线粒体Na+、Ca2+、Mg2+含量及Na+-K+-ATPase 、Ca2+-Mg2+-ATPase 活性的上述改变。结论 SQS 具有抗钠钙超载的心肌细胞保护作用。

Abstract: Aim and Methods To observe the effects of sasanquasaponin(SQS)on the activities of Ca2+-Mg2+-ATPase and Na+-K+-ATPase and the contents of Na+, Ca2+ and Mg2+ in ischemic myocardial mitochondria of rats, my ocardiali schemiarat model was induced by subcutaneous injection of isoprote renol (ISO, 4 mg · kg-1)and some model rats were given SQS (0.2 mg · kg-1)once daily for 3 days.Results As compared with those in the control, myocardial mitochondrial Mg2+ content was markedly reduced, while the contents of Na+ and Ca2+dramatically increased and the activities of Ca2+-Mg2+-ATPase and Na+-K+-ATPase were decreased significantly in ischemic rats administering SQS(0.2 mg · kg-1, iv).Conclusions QS has cytopretectiveef ect by antagonizing the overload of Na+, Ca2+ in ischemic myocardial mitochondria.
