针刺人中对急性脑缺血大鼠海马rCBF神经元超微结构的影响

Effect of Electroacupuncturins Renzhong Point onRegional Cerebral Blood Flow (rCBF) and Ultrastructure inHippocampus of Rats with Acute Partial Cerebral Ischemia

研究结果表明，急性不完全性脑缺血大鼠海马出现局部脑血流量（rCBF）的下降，并伴有海马CA1区神经元超微结构损伤。电针人中穴能够增加缺血海马的rCBF，同时也减轻了因缺血造成的神经细胞损伤。提示针刺人中穴具有抗急性缺血性脑损伤的作用，且与其增加了缺血区的rCBF密切相关。

The study showed that rCBF in hippocampus of rats with acute partial cerebral ischemia was decreased and the ultrastructure of the nerve cells was injured before electroacupuncture.Electroacupuncture at Renzhong can increase the rCBF and rednce the damage of the ultrastructure in hipnyampus from ischemic injury. It indicated that Renzhong point has an antagonistic action on acuteinjury by cerebrAl ischemia and the effect is closely relative to its action.on Increasing rCBF.
