英文摘要
To search the new therapeutic approach to treating neuropathic pain, we investigated the role of nociceptin, pituitary adenylate cyclase activating polypeptide (PACAP), N-acetyl-aspartic-glutamate (NAAG) and orexin-A in spinal nociceptive transmission in the rats. Intrathecal administration of nociceptin, PACAP and orexin-A produced significant analgesic effect in the inflammatory pain models and intrathecal administration of either nociceptin or orexin-A attenuate the level of mechanical allodynia induced by partial sciatic nerve ligation. NAAG was catalyzed by NAALADase and inhibition of spinal NAALADase produced significant analgesic effect in both inflammatory pain models and neuropathic pain models. These data strongly suggested that nociceptin, inhibition of spinal NAALADase and orexin-A are new candidates for treating neuropathic pain in clinical situation.
