摘　　要：本文综述了有关中缝大核内神经细胞的递质性质及其超微结构的特点;中缝大核中枢传入和传出纤维的递质性质和中缝大核的超微结构及其在针刺镇痛中的变化等方面的研究结果。Nucleus Raphe Magnus(NRM)is a complex cell group.5-HT,SP and ENK neurons in theNRM were identified by immunocytochemistry method.The afferent fibers containing 5-HT,SP,M-ENK,L-ENK,B-EP and SRIF were observed in NRM,the efferent fibers containing 5-HT,SP,ENK and TRH from NRM to spinal cord were studied.Two neurotransmitters(such as5-HT with SP,ENK or TRH)were found in same neuron,fiber or vesicle.The neurons andaxo-dendritic synapses of the NRM were analysed during Electroacupuncture(EA).The NRM in-creased their synapitc releases and the neurons were in active functional state during EA“gusnanli”.Studies show that NRM is one of important positions in EA analgesia.
