In the present study

the following experiments were performed on rabbits to evalute the relationship between acupuncture points and visce- ral organs. 1. The effect of electroacupuncture (EA) at "Zusanli" point on auricular responsive points induced by stimulating gastricus vagus. 2. The effect of EA at "Neiguan" point on auricular responsive points induced by stimulating the heart. 3. The effect of EA auricular point on auricu- lar responsive points induecd by stimulating the heart. Measurements were taken on the acupoints of the left side and EA was delivered on the corresponding acupoints of the right side. Methods: For stimulation

a pair of special silver electrode was implanted

under aseptic condition

around the ventralis gastricus branch of the va- gus or in musculus pectoralis in front of the heart and near the esopha- gus at the back of the heart. When recovered from the operation about 7 days

the animals were stimulated in awake condition. During cardiac stimulation

the animals were examined by ECG which serves as an objective index for effectiveness of stimulation. Auricular resistance was measured with high frequency AC dermome- ter once every day before stimulation for 3 days and after stimulation until recovery. Results: 1. After stimulating the ventralis gastricus branch of the vagus

the number of auricular low resistance points(LRP)was increased obviously in abdomen area of auricular

which last for about one week till recovering to the control level. During stimulation

a response of excess- ive secretion of saliva and nasal mucus occured before the increase of LRP. In the group of stimulating gastricus vagus and EA at "Zusanli" the obvious increase of LRP lasting only for 3 days

was less than that in the group of stimulating gastricus vagus alone. The excessive secre- tion of saliva and nasal mucus werealso supressed by EA. 2. After cardi- ac stimulation alone

an obvious increase in number of auricular LRP appeared mainly in thoracic area and maintained for about 3 days

which was significant

as compared with pre-stimulation leve. A change of ECG was found simultaneously. After cardiac stimulation and EA at "Nei- guan"

a less increase in number of auricular LRP was observed. The significant variation lasted only for one day. The change of ECG was less evident that in the group of stimulating the heart alone. 3. After cardiac stimulation

an increase in LRP and change in ECG were also observed. But when the corresponding response points of theopposite side were stimulated every day after cardiac stimulation

the number of LRP decreased rapidly from the highist peak and recovered to the pre-stimu- lation level. The above results indicates that

a significant increase in number of auricular LRP of specific region could be induced by chronic stimulstion of visceral or their distributed nerves

i.e. Viscera-Auricular point Re- sponse. This response could be inhibited by EA at body poins or auri- cular points of the opposite side to a ceratain extent. This suggests the existence of a close relationship between triqartition-body points

au- ricular points and visceralorgans.
