Electroacupuncture could induce the convergence and degranulation of subcutaneous mast cells innupoints. After unilateral transection of sciatic nerve

we studied the numbers of subcutaneous mastcells and its degranulation in bilateral Zusanli and Xiajuxu acupoints with electroacupuncture in Zusan-li. We found that sciatic nerve transection could reduce the total numbers of mast cells and the degranu-lation numbers of mast cells in Zusanli. The results suggested peripheral nerves play an important rolein the convergence and degranulation of mast cells in acupoints by electroacupuncture induction.
