The authors seek a method of stimulating restorative processes in irradiated muscles of old animals. Rats were used in the experiments. Different series of experiments were performed, including complete transverse section of the gastrocnemius muscle after local x-ray irradiation, and laser therapy of the transversly divided gastrocnemius muscle. Post-traumatic regeneration of the gastrocnemius muscle of old rats is illustrated schematically. The experimental data showed that pulsed laser therapy or grafting of minced unirradiated muscle tissue can largely restore the regenerative capacity of the gastrocnemius muscle of old rats when depressed by x-ray irradiation, but the method of grafting minced unirradiated muscle tissue was more effective.
