Abstract

In the paper the results of studies of the absorption and fluorescence spectra of cells and tissues in the (250-1200 nm) are reported. It is shown that irradiation of tissues in the red and near IR regions of spectrum (600-800 mn) is determined by fluorescence of Fe ions equally with the known endogenous fluorophors such as atomic amino acids, reduced NADH, oxidized flavins, and porphyrin compounds. These fluorophors take participation in all basic biochemical and biophysical processes which provide the equilibrium among different gomeostatic systems including immune, hormone, oxidation-reduction ones, etc. Therefore, it is possible to exert a fine control over different gomeostatic mechanisms and to affect the state of the whole organism by the aid of even insignificant external actions imposed on these molecules, for example, by selective photoexcitation of a certain group of fluorophors.
