Outline of Final Research Achievements |
We first established a rat model for the judgement of cell transplantation therapies. Drugs for neuropathic pain were effective in rats with their left sciatic nerve pinched at fixed constant pressure, whereas NSAIDs were ineffective. The rats showed motor function decline represented by Sciatic Function Index from one day to two weeks after surgery. Immunohistochemistry using clipped site of sciatic nerve and dorsal root ganglia showed the evidence of axonopathy and demyelination. Although rat Schwann cells transplantation into injured sites were not clearly effective, statistically significant relief of hyperalgesia was observed with the stronger clip pressure. Above results indicated the possibility of cell transplantation therapies for neuropathic pain.
