Conference paper


The effect of monochromatic electromagnetic radiation in the visible spectral range on human peripheral leucocytes was investigated in allogeneic and mitogenic stimulations as well as in migration inhibition assays. For irradiation we used HeNe-, Ar+-, Kr+-lasers and a thermal light source. The influence of the following parameters of the applied light was considered: wavelength, power density, exposure time, state of polarization and particularly the coherence. No influence of irradiation with any light source was seen in mixed lymphocyte reactions and mitogenic stimulations. In contrast irradiation with coherent HeNe-laser light effected leucocytes in migration inhibition assays. Linearly polarized incoherent light of the same wavelength and power density showed no influence.
