| Abstract: | The functional effects (activation and cell damage) of low-power, continuous-wave HeNe laser irradiation were studied in different
in vitro cultured cell lines. A characteristic dose-dependence was observed between 0.14 and 28.0 J/cm2. The functional activation (increased phagocytic activity, immunoglobulin secretion) or cell destruction could not be detected
after irradiation by normal monochromatic light of the same wavelength and energy output. The experiments suggested that low-power
laser irradiation has a specific influence on the cells which depends on the coherent and polarized physical features of the
laser light. |
