Abstract
Diabetic foot ulcer is a major complication of diabetes mellitus with negative effects on the life quality. Management of diabetic foot ulcers is a big challenge with poor and low sufficient outcome management. Therefore, achievement to effective treatments may treat these ulcers. Nowdays, platelet products are used as an effective and safe agent for promotion of healing proposes in regenerative medicine. Serum rich in growth factors (SRGF) is a source of released growth factors from the platelets. In the present study, effect of allogenous SRGF was investigated on the streptozotocin (STZ)-induced diabetic wounds in rats. STZ (50 mg/kh, SC) caused significant increase in blood glucose and weight loss in rats. Full thickness cutaneous wounds (8 mm diameter) were created bilaterally on the dorsal of the diabetic rats. SRGF was injected at the edges of the wounds of one side only on the first day, and the contrary sides were considered as the control group. The percentage of wound contraction was demonstrared on day 3, 7, 11 after surgery. Tissue specimens were collected for microscopic study on days 7 and 14.Results showed a significant higher rate of wound contraction on days 5 and 7 in the treated group. Histopathologic findings displayed acceleration of re-epithelialization, increased angiogenesis and dense collagen fibers with better organization in the treated group.Current study suggests that SRGF was efficient because facilate wound healing and showed rapid re-epithelialization and increased angiogenesis.
