电针内关穴诱导大鼠延髓原癌基因c-fos表达

Effect of Electro-acupuncture of Neiguan Point on Proto-oncogene c-fos Expression in Rat Medulla Oblongata

【目的】观察电针内关穴诱导大鼠延髓内的原癌基因c -fos表达及分布特点。【方法】采用抗FOS蛋白的免疫组织化学方法。【结果】电针内关穴可引起大鼠延髓内神经元的广泛c -fos表达 ,其FOS样免疫反应 (FOS -like -immunoreactivity ,FLI)阳性神经元广泛分布于延髓的孤束核、迷走神经背核、下橄榄核、楔束核、楔束外核、腹外侧网状核、疑核 ,网状结构中也散在分布着FLI神经元如网状巨细胞核等。【结论】提示电针“内关”穴激活了上肢的本体觉传导路 ,并且激活了延髓内与内脏信息相关的中枢核团。

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. Conclusion Electro_acupuncture of Neiguan point c an activate the proprioceptive pathways and the nucleus in the medulla oblongata that is related to visceral informatio n.
