曾认为末期已分化成熟的心肌细胞不发生细胞凋亡 ,但近来研究发现 ,某些因素可以诱导成年心肌细胞凋亡 ,并且许多心脏疾病的发病过程中有细胞凋亡参与。本实验采用定性定量方法 ,观察了缺血—再灌注损伤诱发心肌细胞凋亡的情况 ,以及人参皂甙单体Ｒｂ1对细胞凋亡的抑制作用1　? It has been considered that terminal differentiated cardiomyocytes do not undergo apoptosis, but recent studies have found that certain factors can induce apoptosis in adult cardiomyocytes, and apoptosis is involved in the pathogenesis of many heart diseases. In this experiment, qualitative and quantitative methods were used to observe the apoptosis of cardiomyocytes induced by ischemia-reperfusion injury and the inhibitory effect of ginsenoside Rb1 on apoptosis.
