Effect of Equal Daily Doses Achieved by Different Power Densities of Low-Level Laser Therapy at 635 nm on Open Skin Wound Healing in Normal and Diabetic Rats
Figure 5
Skin wound after 14 days of healing in diabetic rats. (a) Control wound (granulation tissue of the wound; collagen fibers are colored in pink; arrows marked isolated new vessels). (b) Wound treated at 1 mW/cm2 LLLT (granulation tissue of the wound; collagen fibers are colored in pink; arrows marked isolated new vessels). (c) Wound treated at 5 mW/cm2 LLLT (granulation tissue of the wound rich in new collagen, colored in pink, arrows marked only isolated new vessels in regression). (d) Wound treated at 15 mW/cm2 LLLT (granulation tissue of the wound with a significant amount of new collagen, arrows marked new vessels in regression). VG stain; scale bar represents 200 μm.
