| Outline of Final Research Achievements |
We investigated the effect of DHEAS and PRE-084, which are sigma 1 receptor agonists, on excitatory synaptic transmission in the dorsal horn neurons of the adult rat spinal cord using electrophysiological technique. We demonstrated that DHEAS enhanced excitatory transmission and suppressed inhibitory transmission in spinal lamina II neurons,resulting in showing pronociceptive effects on the spinal cord. On the other hand, PRE-084 showed no obvious effect on spinal dorsal horn neurons.
