[Quantitative analysis for histochemical grouping of muscle fibers after skeletal muscle transplantation by microneurovascular anastomoses].
A poly-histochemical quantitative assay was carried out on fibers of grafted rectus femoris muscles of rabbit which had undergone simulated free muscle transplantation by microneurovascular anastomoses in speciments at 3, 6, 12 months postoperatively. At the same time, the same assay was done for two experimental control groups: either the motor nerve or the patella tendon was simply severed and immediately sutured. It was found that the contractile characteristics of whole muscle were depended on relative number of different muscle fibers. That meant it was depended on the relative number of different motor fibers which had run through the anastomosed site. The caliber change among different types of muscle fibers mainly represented there was cross reneurotization during nerve regeneration.
