THE EFFECT OF HELIUM-NEON LASER, USING DIFFERENT METHODS AND FREQUENCIES OF RADIATION, ON WOUND HEALING
Journal Title: International Journal of Medical and Clinical Research - Year 2014, Vol 5, Issue 1
Abstract
He-Ne laser 632.8 nm plays an important role in wound healing. The aim of this research is to demonstrate the effect of He-Ne Laser on healing of deep wounds in rats employing : I-different methods of irradiation. The first method of irradiation is by a Laser beam spot of 4 mm in diameter. The second method, the spot Laser beam diameter was expand to 1cm by a converging lens, to produce a uniform irradiation on the entire wound length. II-different irradiation frequencies: (1) every other day, (2) daily, and (3) at the first post-operative day only. Eighty eight young male rats were used in this work, they divided in to four groups. The first group consists thirty two rats, which irradiated by He-Ne laser at the first post-operative day only. The second group consists twenty four rats which was exposed to laser every other day. The third group contains twenty four rats was exposed daily. Finally, the fourth group consists eight rats, which was regarded as a control group. A biopsy was taken from all irradiated rats for histological examination at 1, 3, 5, and 7 days post operatively. The results demonstrate a clear promoter of wound healing in irradiated groups. But the best one was found in group treated by He-Ne laser with lens, irradiated every other day.
