Quantum Biology of Laser Photostimulation Most human beings feel excited by sunshine and depressed by prolonged sunlight deprivation. This familiar observation highlights the importance of light in supporting human and other forms of life. Reports that suggest the con -trary, i.e., that low intensity lasers are not effective in these situations, complicate the matter, creating the present scenario in which laser therapy is viewed with skepticism.

Human ulcers respond in the same manner.
That the ulcers were not responding favorably to other forms of therapy before the lasers were used is worthy of note. The work reported here by Ohshiro et al. of Japan Medical Laser Laboratory, and Keio University School of Medicine in Tokyo, Japan, suggests that the stimulating effects of laser therapy may be more extensive than previously thought, i.e., it may have an overall whole body effect. The report of Ailioaie and Ailioaie of the University Department of Medical Physics, Iassy, Romania, further supports the notion that laser therapy can induce whole body responses. Many of these findings are not entirely new, however, the precise mechanisms involved remain unclear, making the contributions of the international group of Sattayut, Hughes and Bradley from Khon Kean University, Thailand, and the Royal London School of Medicine and Dentistry, in the U.K., timely and relevant.
