Acute and chronic wound treatment research on 20 experimental rabbits with 1 percent SSD combines the semiconductor red laser (lamta = 630-670nm), at power density 4J/cm2 compared with the control group treated with 1 percent SSD only. Results: on acute wounds, rabbits systemic manifestation did not change under laser treatment. At 10th day of treatment, the wound surface area in the experimental group was significantly narrower than in control group (3.41 +/- 0.62cm2 vs. 4.18 +/- 0.69cm2; p 0.05). On chronic wounds, closure time of the experimental group was significantly shorter than in control group (27.9 +/- 2.23 days vs. 23. 8 +/- 3.76 days; p 0.05). Exudate level and number of inflammatory cells was also statistically lower than in control group (p 0.05) demonstrating that treatment with laser irradiation in combination with 1 percent SSD reduces inflammation in chronic wound than 1 percent SSD alone.
