| 摘 要： | Histochemistry and EM were used in this experiment to study the effect of EAon the spinal dorsal horn of rat. After 30 minutes EA, the pain threshold of EA rats were elevated400%, the acid phosphatase reaction in spinal dorsal horn of EA rats increased obviously, the roundagranular vesicles of the C-terminals of EA group was more than that of control's. The results sug-gested that the histochemical components and numbers of synaptic vesicles in SG and their functionscould be regulated by acupuncture.
