Repair sciatic nerve gap of the rats with novel artifical nerve guide

ObjectiveTo explore the possibility of repairing sciatic nerve gap of rats with artifical nerve graft.MethodsA novel artifical nerve guide was developed and used to suture the 15 milimeter long right sciatic nerve gap of 10 rats, other 7 rats were the control with the right sciatic nerve gap alone.2 and 4 monthes after operation, immunohistochemistry, Osmium staining, Bodian staining,motor end plate staining,WGA HRP stain tracing have been done to observe the effect of repairing.Results2 months after operations, the sciatic nerve gap were repaired by the regeneration nerve.There was not evident inflammation in the defects.ConclusionsThe artifical nerve graft can induce the nerve to regenerate.
