再灌注时梗塞相应部位的冠状动脉重新开放是治疗急性心肌梗塞的目的,但再灌注期间心肌细胞继续死亡。对这种细胞死亡的机制尚有争议。凋亡是一种形态学上特有的,受遗传调控的细胞死亡类型。DNA基因组经内源性核酸内切酶作用大量断裂成核小体样片段是凋亡的生化特点。该研究旨在观
The reopening of coronary arteries at the corresponding site of infarction at reperfusion is the goal of treating acute myocardial infarction, but cardiomyocytes continue to die during reperfusion. The mechanism of this cell death is still controversial. Apoptosis is a morphologically specific, genetically controlled type of cell death. DNA genome by endogenous endonuclease large number of nucleosome-like fragments fragmentation is the biochemical characteristics of apoptosis. The study aims to observe
