[A comparative analysis of the action of red and infrared laser radiation and ultrasound on the regeneration of locally irradiated skeletal muscle and on immune system function in the rat].

The study was made of a regeneration ability of the rat skeletal muscle which had been mechanically injured and exposed to a 20 Gy irradiation, of the thymus and bone marrow condition after local exposure of the muscle to red and infrared laser radiation and ultrasound. These factors were found to stimulate regeneration of the injured soft tissues and to reduce cytogenetic damage to bone marrow cells in the irradiated zone under growing immunosuppression. The stimulation was most potent in prolonged exposure to the ultrasound.
