| Abstract: | The effect of laser (632 nm) and LED (630 nm) on lipid peroxidation in rat wound fluid (exudate) was studied with the aim of comparing the efficiency of coherent and incoherent light on the processes that take place during wound healing. The study was performed using the model of cut aseptic wounds proposed by L.I. Slutskii. It was shown that irradiation of wounds with light of both laser and LED caused a decrease in the concentration of lipid peroxidation products in wound fluid as compared with the control group. An increase in the antioxidative activity of wound fluid was observed. It was concluded that irradiation with light of both laser and LED decreases the level of oxidative stress in wound fluid and that radiation coherence does not play a significant role. |
