Paper Abstract

Effects of laser at the wavelength of 650 nm on the isolated vessels of white rat mesentery have been analyzed. Influence of laser irradiation on the statement of blood microcirculation in mucous membrane of human oral cavity has been investigated. Temporal changes of hemodynamics have been studied by methods of laser photoplethysmography, Doppler diagnostics and laser speckle imaging technique. Influence of coherent light (at the wavelength 630 nm) on the intensity of microcirculation in the capillary net of mucous membrane has been demonstrated directly during the short-time session of laser therapy.
