This is a report of our experiences gained in experimental and clinical results on wound healing. The open skin wounds in ginea pigs were irradiated with an argon laser, non-polarized and linearly polarized light from nearinfrared light emitting diodes (LED) and light from cemiconductor laser diodes. The rate of wound closure was followed by photographing the wounds in a standardized way. Argon laser and linearly polarized light from LED radiation had a statistically significant stimulating effect.
As clinical application, 50 wounds which had resisted most types of conventional wound treating methods were irradiated with argon laser and 28 healed. Eighty seven wound were treated with LED polarized light and 67 healed or improved. Therefore the application of linearly polarized light included laser to stimulate wound healing in cases of nonhealing ulcers is recommended.
