摘要
本文采用脑刺激和损毁法,探讨了大鼠下丘脑室旁核(PVH)在针刺镇痛中的作用。结果表明:电刺激PVH及PVH内微量注射谷氨酸钠均可增强“足三里”的针刺镇痛效果,呈量效关系;电解损毁PVH则削弱针刺镇痛效果;去除脑下垂体不能抑制PVH内注射谷氨酸钠的作用。
The role of hypothalamic paraventricular nucleus (PVH) in acupuncture analgesia was investigated by local brain stimulation and cauterization. Theresults showed that electrical or L-glutamate sodium stimulation of PVH couldenhance the effect of analgesia of Zusanli acupuncture, both in a dose dependentmanner. Electrical cauterization of PVH decreased the effect of acupunctureanalgesia, while removal of pituitary had no effect on the enhancing effect byL-glutamate sodium injection.
