The effect of 632 nm and 360 nm light on NIH fibroblast cells was examined. Mitosis counts of irradiated cells at various energy doses were taken. Scanning Electron Micrographs of these cells enriched and nonenriched with porphyrins were studied. It is suggested that low-level laser therapy (LLLT) in the visible and in the far infra-red region is due to cell respiration stimulation by either the endogeneous porphyrins in the cell, or by the cytochromes.
