Research Abstract	The purpose of this study was to evaluate role of spinal microglia for hypersensitivity in postoperative pain and neuropathic pain. For postoperative pain, using rat model of postoperative pain, microglial inhibitors were injected into rats with paw incision to examine the role of spinal microglia in postoperative hypersensitivity In neuropathic pain model, rats were received microglial inhibitors immediately, 2 weeks and 2 months after L5 spinal nerve transection to determine when microglia have a most important role in the development and maintenance of neuropathic pain. I finished 70% of this study right now. Therefore, I will do my best to continue and complete this study.
