Wound healing remains a challenging clinical problem, especially in the presence of diabetes. Diabetic patients have the impaired ability to fight infection and insufficient inflammatory response. The aim of this study was to evaluate the effects of boronophenylalanine (BFA) and/or Zn-containing nanoemulsion (NE) formulations on wound healing in diabetic rats. MTT and scratch assays were performed to evaluate the proliferative effects of BFA and/or Zn on human dermal fibroblast (HDF) cells and the migration of these cells, respectively. The BFA and/or Zn-NE were prepared, and the effects of NEs on wound healing in diabetic rats were evaluated by applying once a day for 14 days. MTT assay showed that 10 to 25 mu M BFA and/or 50 mu M Zn had very significant positive effects on cell proliferation. In the scratch assay, 10 mu M BFA significantly increased the migration of HDF cell compared with control. The droplet sizes of all the NEs were <115 nm and their zeta potential values were in range of (-) 23.9 +/- 2.356 to (-) 33.1 +/- 1.438 mV. There was a significant reduction in the wound contraction values (%) of the groups treated with the BFA and/or Zn-NE on the 14th day compared with the untreated diabetic rats group. According to histopathological findings, wound healing was nearly complete in BFA and/or Zn-NE compared with untreated diabetic rats. Especially, the group treated with the NE containing the low concentration of BFA showed highly promising results in wound healing of diabetic rats within 14 days with complete epithelialization and the completely closed wound area.
