Plasticity of allogeneic muscle tissue implanted into a traumatized rat muscle on exposure to He-Ne laser light

The combined effect of muscle tissue alloplasty and He-Ne laser light on the regeneration of a traumatized skeletal muscle was studied. In implantation of untreated allogeneic tissue into the region of transverse cutting of the gastrocnemius muscle exposed to laser light in vivo before surgery, the muscle regeneration in recipient rats was successful. Active regeneration of the allogeneic tissue and the muscle tissue of the recipient rat was noted. In implantation of laser-exposed allogeneic tissue into the region of trauma of unexposed gastrocnemius muscle, the muscle regeneration was less successful. The alloplastic implant was replaced by connective tissue and prevented the growth of the muscle tissue of the recipient rat in the defective zone. Implantation of laser-exposed allogeneic muscle tissue into the region of trauma of the muscle x-irradiated to a dose of 20 Gy enhanced destructive processes in it.
