Abstract

Objective To examine the proto_oncoge ne c_f os expression and its distribution in rat medulla oblongata induced by electro_a cupuncture of Neiguan point. Methods Anti_c_fos immunohistochemical method w as applied. Results Fos_like immunoreactive positive neurons mainly located in nucleus tractus solitarius, dorsal motor nucleus of vagus nerve, inferior ol ive nucleus, cuneate nucleus, external cuneate nucleus, and ventrolateral m edulla(VLM). VLM included lateral reticular nucleus, ambiguous nucleus and the s urrou nding reticular structure.
