[Effect of helium-neon laser rays on the process of postradiation recovery in skeletal muscle tissues].

Three series of experiments were conducted on the gastrocnemius muscle of rats. In the first series the entire muscles were autografted. In the second series autografting of the muscles was preceeded by irradiation of both hind limbs at a dose of 1000 R. In the third series x-ray irradiation at the limbs with helium-neon laser whereupon the muscles were autografted. The transplantation regeneration was studied histologically after 2 weeks, one and two months. It was established that exposure to laser stimulates cell reparation in the skeletal muscle tissues and makes post-traumatic regeneration depressed by x-rays return to normal.
