在动物实验观察到针刺可兴奋Ⅰ、Ⅱ、Ⅲ、Ⅵ各类传入纤维,但哪类纤维在镇痛中起主要作用?尚有不同看法。为了进一步探讨这一问题,首先要建立动物模型。用于研究镇痛的动物模型已有不少报道。如下颌运动模型简便而又可显示出较高中枢的情况,我们就此加上某些改进后,用以观察在某些条件下针刺镇痛的作用,为进一步分析针刺镇痛传入纤维类型刽造必要条件。 In animal experiments, it is observed that acupuncture can excite various kinds of afferent fibers of Ⅰ, Ⅱ, Ⅲ and Ⅵ, but which kind of fibers play a major role in analgesia? In order to further explore this issue, we must first establish an animal model. There have been many reports of animal models used to study analgesia. Such as jaw movement model is simple and can show a higher central situation, we add some improvements, to observe the effect of acupuncture analgesia under certain conditions, for further analysis of acupuncture analgesic afferent fibers Type 刽 made the necessary conditions.
