Paper Abstract

At present, foolproof methods are needed for control of low-power light biomedical effects. Transmission spectra of whole blood from 108 patients were recorded before and after action of low-intensity He-Ne laser and extracorporal UV irradiation. We have observed changes in the blood transmission spectrum caused by oxygen saturation changes in venous blood. It has shown that He-Ne laser irradiation more selectively acts to venous blood than extracorporal UV irradiation.
