The changes of the discharge from postganglionic fibers of the celiac ganglion induced by electroacupuncture(EA) at Zusanli and Yanglingquan were measured on 25 healthy rabbits. The result shows that the sympathetic activity can be inhibited by EA at both acupoints above. The depression of the sympathetic activity resulted from EA at Zusanli was significant stronger than that at Yanglingquan(P<0.05). This result indicates that there is the relative individuality in the function of the different acupoints on the different channels
