心肌顿抑(Myocardialstunning,MS)是临床上常见的短暂心肌缺血后心功能障碍,离体心脏试验显示心肌质膜Na+-K”.ATP酶、内质网Ca’”-ATP酶活性降低与MS的发生有关。作者观察了在体大鼠MS时心肌质膜、内质网和线粒体CaZ”-ATP酶活性及心肌ATP含量的变化,旨在进一步探
Myocardial stasis (MS) is a common cardiac dysfunction after transient myocardial ischemia in vitro. In vitro cardiac studies showed that the activity of Na + -K “.ATPase, endoplasmic reticulum Ca ’” -ATPase decreased MS related to the occurrence. The authors observed changes in CaZ "-ATPase activity and myocardial ATP content in the plasma, endoplasmic reticulum and mitochondria of rats in vivo MS, aiming to further explore
