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 4
Skin wound after 6 days of healing in diabetic rats. (a) Control wound (1—granulation tissue of the wound, arrows marked isolated new vessels). (b) Wound treated at 1 mW/cm2 LLLT (1—granulation tissue of the wound, arrows marked proliferating fibroblasts and forming new vessels). (c) Wound treated at 5 mW/cm2 LLLT (1—proliferating fibroblasts, 2—granulation tissue rich in new collagen, arrows marked forming new vessels). (d) Wound treated at 15 mW/cm2 LLLT (1—proliferating fibroblasts, 2—granulation tissue rich in new collagen, arrows marked forming new vessels). HE stain; scale bar represents 500 μm.
