[Effects of autotransplantation of minced muscle tissue and subsequent laser therapy on recovery of the muscle injured by irradiation].

A comparative histological investigation of posttraumatic regeneration in irradiated with 30 or 40 Gy and cross-sectioned musculus gastrocnemius of rats after autotransplantation into muscle defect of non-irradiated minced muscle tissue and laser therapy of hind limb in post-operative period was conducted. The obtained results showed that in irradiated with 30 Gy sectioned muscle (control series) the inflammatory reaction, resorption of fibrin in the area of trauma were inhibited and proliferation of muscle tissue from proximal and distal stump was suppressed. The rough connective tissue scar was formed. In experimental series for stimulation of regeneration the method of autografting minced muscle tissue into the defect of irradiated (30 or 40 Gy) cross-sectioned muscle and combination of this method with helium-neon laser rays exposition was used. The more marked recovery was obtained in irradiated with 30 Gy operated muscle after a 10-day treatment of limb with laser rays.
