摘要(Abstract):
本研究运用TUNEL染色法观察电针对大鼠脑缺血后脑内神经细胞凋亡的影响。结果显示:在假手术组和单纯电针组,大鼠脑内未见神经细胞凋亡,脑缺血后12小时,大脑皮层梗塞区内大量的神经细胞凋亡,在缺血十电针组,大脑皮层梗塞区内神经细胞凋亡数目显著减少。结果表明:电针抑制脑缺血后脑内神经细胞凋亡。
In this study, TUNEL staining was used to observe the effect of electro-acupuncture(EA) on apoptotic neuronal death induced by focal cerebral ischemia in rats. The results were as follows: In the sham-operated group and the EA treated group, TUNEL positive stained cell was not detected in the brain. In the ischemic group, a large number of apoptotic neuronal cells were detected in the infarcted area of cerebral cortex at 12h postischemia. In the ischemia + EA treated group, the number of apoptotic neuronal cells in the infarcted area reduced significantly. The results suggest that EA inhibits apoptotic neuronal death induced by focal cerebral ischemia.
