| Outline of Final Research Achievements |
We have reported that one of the antinociceptive mechanisms of beta-endorphin acted without releasing of substance P from primary afferent. In order to further elucidate such mechanisms, we assessed the optical synaptic transmission for neuropathic mice by using brain vison system.
Electrical stimulation of dorsal root ganglion showed that fluorescent change of voltage-sensitive dye in dorsal horn in a sequential manner, and the ratio of the release of substance P rised compared with control group.
