[Features of the structural-functional organization of muscles of replanted rat limb]

The article characterizes the structural-functional organization of fast and slow muscles of replanted rat limb by methods of light-optic, ultrastructural, and morphometric analysis. The results of the study allowed a conclusion to be drawn that the initial organization of the muscles is not restored in the late terms after replantation. New structural-functional units form in them which differ from the initial system of functioning and vitality provision. Grounds for advancement of destructive-degenerative changes are laid down in the newly formed system of neuro-muscular and vascular-tissue relations. The possible vascular, neural, and autoimmune mechanisms of timing of the pathological process in the replant muscles are discussed.
