The article summarizes the achievements of research on the mechanism of auriculo-acu-points by us in recent years.(1) By stimulating and recording the electric activities of the sympathetic nerve, it has been observed that the abnormal sympathetic excitation is the cause for the reduction of the electric resistance itt ear acupoints, the occurrence of the low-resistance spots in the auricle, and the auricular resistance has a phasic process of rising ahead and falling behind, we have observed that the quantity change of the low-resistance spots in the auricle is parallel to the quantity of the syrnpathetlc fibres, with local injection of the specific sympathetic-destroying agent, 6-OHDA.(2) It was confirmed with animal cross-circulation method that humour factors participate in the viscera-auriculo-acupoint response. Furthermore, the adrenal effect was proved with the adrenal extirpation. A several models of Yang-deficiency syndrome were rnade to analyze the action of some substaflces secreted from adrenal cortex and adrenal medulla.(3) On the basis of the above-mentioned outcome, a hypothesis that specific and nonspecif1c viscera-auriculo-acupoint responses are mixed has been rendered, The specific response here means the special relationship between certain parts of the auricle and certain viscera which forms the foundation of auriculo-acupoints, while the nonspecific one refers to the general or diffused response in the whole auricle resulting from the actions of all the viscera and other parts of the body. The specific response may be fulfilled by the sympathetic nerve, wh1le the nonspecific response is accomplished by both of sympathetic nerve and adrenal gland. The significance of the research may be concluded in the following: the mechanism of auricle diagnosis in clinic has been further understood; the diagnostic accurracy and the therapeutical effect could be raised and a new breakthrough for expounding the substance of meridians and collaterals could be ma
