title: [DNA contents and cycle analysis of porcine burn wounds treated with growth factors].
abstract: Wound healing is a complex biologic process in which peptide growth factors play a very important role. The object of this research was to study the effects of recombinant human epidermal growth factors (rh-EGF) and acidic fibroblast growth factor (aFGF), basic fibroblast growth factor (bFGF) and bovine brain extract (bBE) on porcine partial-thickness burn wound healing. The biopsies were taken for determination of DNA contents and cell DNA cycle with the aid of flow cytometry and histological observation. The results showed that more extensive reepithelization and greater thickness of epidermis exhibited in growth factor treated wounds, and DNA contents and percent of S phase of cell DNA cycle were also higher in those groups treated with growth factors. The results suggested that repeated topical application of rh-EGF, aFGF, bFGF and bBE accelerated epithelial healing of burn wounds, and it may be helpful in clinical practice.
