Effect of Light Therapy of Blue LEDs Irradiation on Sprague Dawley Rat

摘要

In order to examine the healing effect of the blue light emitting diode (LED) irradiation on skin wounds, a round slice of wound 1 cm in diameter was cut on the back of the laboratory animal. Animals treated with blue light emitting diode (LED) irradiation (p < 0.05) healed at a faster rate than non-irradiated controls. The blue light emitting diode (LED) irradiated groups also had more collagen, according to Masson's trichrome staining for collagen analysis. In conclusion, blue light emitting diode (LED) irradiation had a beneficial effect on wound healing and could probably replace low level laser therapy.
