[Effects of minced muscle tissue implantation and subsequent laser therapy on regeneration of skeletal muscles in guinea pigs].

It is known that regenerative capacity of skeletal muscles in guinea pigs is less than in rats. The guinea pig muscle regenerates are characterized by smaller muscle fibers and greater amounts of interstitial connective tissue. The present experiments were designed to stimulate the regenerative capacity of muscle tissue in adult guinea pigs, using tissue and laser therapy. It was shown that the minced muscle tissue implantation to the site of injury in m. gastrocnemius increased the quantity of regenerating muscle tissue. When the same operation was combined with following laser therapy the increase of muscle tissue was observed as well but not by far. At the same time laser therapy promoted noticeable acceleration of fibrin resorption, wound healing and regenerative modifications in implanted muscle fragments. Thus, the present methods stimulated relatively law regenerative capacity of guinea pig muscle tissue and promoted more qualitative recovery of injured area.
