Purpose: The purpose of this study was to investigate the effect of Ulmus root-bark dressing in fibroblast growth factor (FGF) and vascular endothelial growth factor (VEGF) of induced pressure ulcers in rats.
Methods: 54 male Sprague-Dawley rats were used and randomly divided into 2 groups. The rats were anesthetized and pressure ulcers were induced at 140 mmHg for three hours, using a personally-designed pressing apparatus. Ulmus dressing was applied in the experimental group (n=27) and saline gauze dressing in the control group (n=27). Each of the dressings was changed every other day, and after a month, the wounds were examined by microscopy biweekly for 20 weeks.
Results: After 4 weeks, the epidermis of the wounds was recovered, but inflammatory infiltration of the dermis was remained. After 6 weeks, inflammatory cells were diminished and the number of capillaries was decreased. Examined by immunofluorescence staining, the FGF positive cells in the experimental group changed negatively after 18 weeks, but the control group still existed even after 20 weeks. VEGF positive cells in the experimental group also changed negatively after 20 weeks, but the control group still existed.
Conclusion: The findings of this study demonstrate that Ulmus dressing is effective in minimizing scar formation and inflammatory reaction by decreasing FGF and VEGF in the terminal phase of wound healing.
