ABSTRACT
Laser radiation has come into wide and varied used in biology and medicine. In biology lasers are used for study of the molecular processes by spectral methods, to investigate the microstructure and state of the cells, for the selective exposure of certain biomolecules to laser pulses, etc. The best studied applications of lasers in medicine are determined by thermal effects. In surgery focused laser radiation with a power of several tens of watts represents a “light scalpel” permitting operations in blood free and sterile conditions. All biomedical laser applications are based on the interaction of laser light with biological systems. On the one hand, low-power laser therapy is undoubtedly successful in treating trophic ulcers and indolent wounds of diverse etiology, as well as some other deseases when traditional drug treatments are of low efficiency. On the other hand, the method seems to be highly incredible and even mysterious.
