The Relationship of C Fiber to 5-hydroxytryptamine in Spinal Cord of Rat in Electroacupuncture Analgesia[J]. Acupuncture research, 1996, (4): 22-24.DOI:
it was observed that electroacupunture at "Huantiao"points of rat could derease the content of 5-hydroxytryptamine(5-HT)and increase the content of 5-hydroxyindoleacetic acid(5-HIAA)in spinal cord.However
the above effects of electroacupunture were obviously treduced after the C fibers of rats had been destroyed by capsaicin
which suggesting that capsaicinsensitive C fiber might take part in the roles of electroacupuncture's promoting the release and utilization of 5-HT in spinal cord
