摘要
通过对65例疼痛症的电针治疗,比较了巨刺与患侧针刺的镇痛效应,证实了同、对侧刺激有相似的止痛作用。通过检测大鼠痛阈和记录D-PAG神经元活动,观察到同、对侧电针均不能提高一侧D-PAG损毁大鼠的痛阈,同、对侧电针"足三里"时,均能在一侧D-PAG核团记录到兴奋的细胞放电。实验结果表明巨刺与患侧针刺镇痛有着相同的高位中枢传入途径。
Through the treatment of 65 cases of painful diseases with electroacupuncture, in comparing with the analgesic effect of contralateral stimulation(CS) and ipsilateral stimulation(IS), it was verified that IS and CS had the similar effect on pain-relieving, while CS was better in improving motor impairment. By testing the rat's pain threshold and recording the neuronal activity in the D-PAG,it was found that neither IS nor CS could increase the pain threshold in the unilateral D-PAG lesioned rats, and the excited neuronal discharge was recorded in the unilateral D-PAG by stimulating rat's Zusanli(ST 36)at each side. It indicates that IS and CS might share the same high level afferent pathway in acupuncture analgesia in CNS.
