Basic Research Proves Efficiency of Magnetic and Laser Field Combination in Phototherapy. Prof. Dr. H.Friedmann

One of the basic mechanisms of photo-bio-modulation is the acceleration of electron transfer by electromagnetic radiation in the visible and near infra-red region of the spectrum [1,2]. In the presence of an electron acceptor such as molecular oxygen (O2), electron transfer reduces O2 to the super-oxide anion O2 , which subsequently dismutates into hydrogen peroxide (H2O2) [3]. Both O2 and H2O2 are highly reactive oxygen species (ROS). Acceleration of electron transfer also increases adenosine triphosphate (ATP) production by the respiratory chain in the mitochondria via the reduction of O2 to water [1,2]. ATP is the fuel that drives protein production and hence cell proliferation and regulates ion transport via the cell membranes. As a result of electron transfer, the redox state of the cell is displaced to a more oxidized redox state.
