Research Abstract |
In the chronic pain animal model caused by muscle insult with immuno-inflammatory and nociceptive stimuli, it was clarified that the delicate interaction between the immuno-inflammatory background and the nociceptive neural inputs may be essential to form long-persisting hypersensitivity, because pretreatment with larger-dose of immuno-inflammatory agent or treatment to immature animal prevented the development of long lasting hypersensitivity. In the cast immobilization model, it was observed that activation of spinal glial cells spread in response to spreading hypersensitivity. The sympathetic activity in this model was augmented during unilateral immobilizing, and then decreased below normal level while persisting pain behavior continued.
