| Research Abstract |
This study focused on the cannabinoid-induced analgesic effect at the level of the spinal cord. Spinal administration of ACEA inhibited the withdrawal latency to noxious heat. Next the change of EPSC in chemotherapy-induced peripheral neuropathy model was examined using in vivo patch-clamp recording. Spontaneous EPSCs and cold stimuli-induced EPSCs increased in the neuropathy model compared to those in sham model, and they were suppressed after ACEA perfusion. The spinal administration of cannabinoids produces the analgesic effects by inhibition of EPSC.
