摘要

Our previous studies demonstrated that topic application of recombinant human acid fibroblast growth factor (aFGF) significantly, but still not completely, improved in diabetic ulcer healing. To obtain a maximal therapy for diabetic ulcer healing, a combined protocol containing aFGF, anti-oxidative reagent zinc (Zn) and stem cell stimulator granulocyte colony-stimulating factor (G-CSF), i.e.: aFGF/G-CSF/zinc sulphate (ZnSO_4), was explored in the present study. Diabetes was induced by a single dose of streptozotocin (STZ, 55 mg/kg) in Sprague Dawley rats, and full thickness skin wound was made in diabetic rats at 2 months after diabetes onset. Diabetic ulcer rats were treated with aFGF, G-CSF, ZnSO_4, aFGF/G-CSF/ZnSO_4 or vehicle control, respectively and 3, 6, 9, 12, 15, 18, 21 and 28 days later, therapeutic effects were evaluated by calculating ulcer area. On day 7, 14, 21 after treatment, rats were sacrificed to collect 2 pieces of dorsal skin from 3 different sites (wound center, edge and healed area) to perform histopathological examination.
