[Effects of helium-neon laser on regeneration capacity of skeletal muscles of adult guinea pigs].
The muscle regeneration was studied in across-cut gastrocnemius muscle of adult guinea pigs. Both hind guinea pig legs were exposed to laser therapy (3-9 procedures for 5 min each) after operation. It was shown that laser therapy accelerated fibrin resorption and wound healing, decreased the muscle fiber degeneration, increased DNA and RNA synthesis in regenerating tissues, stimulated regenerative muscle fiber capacity. However, the regenerating muscle tissue did not connect both muscle stumps, and the narrow connective tissue scar was formed. Before it was shown that the same laser therapy conditions were more effective for rats. Probably, the stimulating effect of laser rays on regenerative tissue ability depends on species peculiarities of animals.
