Paper Abstract

The 632.8 nm wavelength low intensity He-Ne laser was used to irradiate on 40 rats which have skin scalded wound with three different laser dose. We observed that: (1) The wound healing process was accelerated by laser irradiation. (2) After laser irradiation for 14 days, the healed-up skin was cut off, the healing process of the new wound was delayed than the groups which also have new wound but without laser irradiation. (3) Both of above appearances were related with the laser dose. In each stage of healing process, the healing speeds were different. Our observation shows that the low intensity He-Ne laser (632.8 nm) irradiation can accelerate the healing process of skin scalded wound in rats, but it can delay the healing process of new open cutting wound which was made after the laser irradiation, especially when using little dose laser. Thus, it must be noted that new wound should be avoid before the healing process completed.
