Wound healing is a complex and highly organized biological response to injury that results in the loss of tissue integrity. Our particular interest was propolis, traditional used as an antimicrobial and an anti-inflammatory agent. The purpose of this study was to see the effects of propolis on healing of the laser induced wounds and the level of collagen formation. 808 ㎚ laser (20 J) was irradiated on the back of rats. Irradiated wounds were divided into gel control and 6 experimental groups (3 and 5% of different three kinds of propolis). Gel type of propolis (supplied by Seoul Propolis Co., Daejeon, Korea) in water based were applied on the laser wound once daily for 14 days. One fourth of rats were sacrificed on 3rd, 7th, 10th, and 14th day and each wound was evaluated for degree of wound healing and the level of collagen formation. Healing of wound was evaluated by measuring and comparing the width and depth of the wounds. The levels of collagen were increased in 3 and 5% gel groups comparing to control on 3rd day and the collagen level were increased more on 7th day. Wounds of the experimental groups showed better healing in width comparing to the healing of the control. The results of this study demonstrated that propolis accelerated healing of wounds induced by laser irradiation and good collagen formation.
