| Research Abstract |
The aim of this project was to explore the mechanism of chronic pain (neuropathic pain) and establish its treatment using the genetic engineering approach. As one of target receptors involved in the mechanism of chronic pain, we have focused on the NMDA receptors in the central nervous system. First, we examined the interactions of NMDA receptor and the neuropathic agents such as local anesthetics, general anesthetics using the recombinant receptor technique. Then we tried to examine the role of NMDA receptor in the neuropathic pain model rat using the anti-sense strategy by adenovirus vectors. However, the effectiveness of the receptor knock down technique by adenovirus was poor to affect in vivo the neuropathic pain of the rat model and this methods have resulted in not getting reproducible data. Therefore in this reports we addressed to the specific interactions of the neuropathic drugs and central nervous receptors related to the pain sensation such as NMDA, 5HT3 and GABA_A receptors.
