以前研究认为脑缺血中的细胞死亡是一种被动的坏死,然而最近研究提示缺血可能引起神经细胞凋亡,细胞凋亡是否为迟发性神经元损害的一种形式,还未得到证实。本实验应用先进的原位末端标记技术在大鼠脑缺血模型中证实了细胞凋亡存在,研究其发生规律,有助于认识缺血时神经元死亡的 Previous studies suggest that cell death in cerebral ischemia is a passive necrosis, but recent studies suggest that ischemia may cause neuronal apoptosis, whether apoptosis is a form of delayed neuronal damage has not been confirmed . In this study, advanced in situ terminal labeling technique was used to confirm the existence of apoptosis in rat cerebral ischemia model, to study its occurrence and help to know the neuronal death in ischemia
