[Effects of low-intensity garnet laser irradiation on microorganisms and wounds]

The influence of low-intensity garnet laser radiation a wavelength of 0.53 microns (green spectrum) on Mycobacterium tuberculosis (MT), nonspecific microflora and regeneration of aseptic and purulent wounds has been studied experimentally for the first time. Irradiation of MT and nonspecific microflora inoculations has shown that this type of laser radiation fails to stimulate growth of MT and nonspecific microflora and has an inhibiting action on MT manifested by delayed MT growth, a lower number of dimensions of the growth colonies as compared to those of the control inoculations and has a bacteriostatic action on micrococci and Neisseria organisms. Influence of this type of laser on the aseptic and purulent wounds in 50 guinea pigs has revealed a more rapid regeneration of aseptic wounds (by 3-4 days) as compared to the control.
