Research Abstract

Thoracodorsal nerve and vein were cut and the proximal end of the nerve was anastomosed to the distal end of the vein. It was found that a newly regenerated nerve which runs through the vein innervates a latissimus dorsi muscle of a rat. Then, the sciatic nerve and the femora vein of a rat were also cut and the proximal end of the nerve and the distal end of the vein was anastomosed. The regenerated nerve also ran through the vein, but the maximum length it ran through was about 1cm long.
