[Tissue interactions of regenerating muscle tissue with skeletal muscle under the effect of ionizing radiation].
The effect of the muscle tissue, ground into a fine chyme, to restoration of the m. gastrocnemius ability to posttraumatic regeneration after x-ray radiation in the doses 20--30 Gy, has been studied in 64 non-inbred white male rats with the body mass about 200 g. The ground muscle is a viscous mass, consisting of finest scraps of muscle fibers, pieces of sarcolemmal tubules with 2--3 nuclei and separate cells. The great destruction of the muscle stroma relieves metabolites to get out and to diffuse. As demonstrate the histological investigations carried out for 1 month, an essential part of the muscle autotransplant, put into the irradiated extremity, regenerates up to formation of differentiated muscle fibers and promotes to restore the regenerative activity in the irradiated m. gastrocnemius.
