摘要
The present study was aimed at the investigation of the ultrastructuralchanges of nucleus centromedianus(CM)of nuclei intralaminares under acupuncture analge-sia.The results of the observations on 18 healthy and adult rats were as follows.1.Thesynapses of the CM belong mainly to the axodendricular synapses and also with some suc-cessive or juxtaposing synapses.2.The presynaptic sac contains a lot of round and clearvesicles,some granular vesicles also spread among clear vesicles in a few synapses.3.Theround clear synaptic vesicles of CM in the electroacupuncture analgesia(EA)group are de-creased significantly than that in the control group.It is suggested that CM plays a role inacupuncture analgesia.
