| Research Abstract |
In chronic pain conditions including neuropathic and inflammatory pain, enhanced efficacy of synaptic transmission in the spinal dorsal horn contributes largely to hyperalgesia and tactile allodynia. Moreover, patients with chronic pain frequently express various symptoms of neuropsychologic impairment, including chronic fatigue, depression, anxiety, sleep disturbance and cognitive deficits, which further affects quality of life. In the study presented here, in particular focusing on monoamines, glycine and acetylcholine, behavioral studies as well as in vivo and in vitro electrophysiological studies were made to explore pathophysiology of neuropathic pain and the effects of some potentially analgesic drugs, which we consider is important to obtain crucial information for developing novel analgesic drugs to treat patients with chronic pain.
