Vitamin D treatment accelerated diabetic wound healing. (a) 6 mm diameter wounds were created by punch biopsy, and the closure of the wound area was measured by digital camera every 3 days until day 14. (b) Percentage of wound closure (means ± SD). Healing of diabetic wounds significantly delayed compared with normal wounds. Vitamin D began to improve diabetic wound closure on day 6. At the end of the observation (day 14), the VD treatment group exhibited improved wound healing, compared with the diabetic group.
