| Research Abstract |
Experimental study using the rectus femoris muscle of rabbits was performed to investigate the recovery process of the muscle transplantation with microneurovascular anastomosis.After 2~24 postoperative weeks, tissue specimens obtained from muscle tissue were examined for pathological analysis. In the pathological analysis, fluorescent staining was used for visualizing the muscle fibers and distribution of acetylcholine receptors together with H-E staining and Azan staining.Wet weight of transplanted muscle had gradually increased after it decreased to about half of control model in innervation model. Degeneration and recovery of muscle fibers were confirmed by H-E and Azan staining in the each model, although the comfortable result for statistical analysis could not be obtained in the fluorescent staining, because the determination of the distribution of acetylcholine receptor was unstable.
