In this study, rabbits with their common bile ducts obstructed were used, the changes of myoelectric frequency were taken as the index, and the effect of emitted qi on the needles which were inserted into zusanli points bilaterally was achiever. In the experiment, the rabbits were operated on to block their common bile ducts and the electrodes were put on Oddi's sphincter to induced myoelectric signals. The records were observed through an ST-41 multichannel physiological recorder. The rabbits were divided into three groups. In the emitted qi group, zusanli points were needled bilaterally, emitted qi was given to the place of the needle body which is 3-5 cm away from the end of the needle for 30 minutes after 10 minutes of recording the myoelectric signals. Then the myoelectric signals were again recorded for 30 minutes after the emitted qi was stopped. Myoelectric signals were taken during 10' before emitted qi was given; during 0-10', 10'-20' and 20'-30' when emitted qi was given; and during 0-10', 10'-20' and 20'-30' after emitted qi was stopped. In the acupuncture controlled group, zusanli points were needled bilaterally and the myoelectric signals were recorded for 30 minutes just after the needles were inserted. In the general controlled group, myoelectric signals were recorded for 70 minutes without acupuncture and emitted qi. The results showed that comparison with that before emitted qi, the myoelectric frequency decreased significantly during emitted qi or 30 minutes after stopping emitted qi. There was no significant differences between the acupuncture controlled group and the general controlled group. This indicated that emitted qi might go through the needle body into the point and channel to make the tensity of Oddi's sphincter reduce, so benefiting excretion of bile and gallstones, relieving pain and diminishing inflammation.
