Abstract
Experiments irradiated by straight polarized light caused acceleration of wound healing. In case of using the right-hand circular polarized light, the first experiment showed that the effect was noticed on both the irradiated and non-irradiated side. However, in the repeated experiment, the effect was observed only on the irradiated side. However, there was no effect by the left-hand polarized light. Laser which was actually a straight polarized light was changed to a circular polarized light in a few cases. In this group, little effect was obtained by irradiating left-hand polarized light using 1.3μm laser diode, 514.5nm Argon laser or 632.8nm He-Ne laser. This finding strongly suggested that there might be a difference between the left- and right-hand circular polarized light on the heling of experimental wound. More informations on such a mechanism requires further study.
