    Abstract:
    OBJECTIVE: To observe the effect of composite skin graft consisting of heterogeneous (swine) acellular dermal matrix and combined micro-autograft and allograft with the aim at overcoming shortcomings of repairing materials for burn wound. METHODS: Forty-eight Sprague-Dawley rats with full-thickness skin defect on the back were grafted with the composite skin (compound skin grafting group, G) and autologous particulate skin (control group, C), respectively. The area of wound healing and the rates of wound contraction were measured. Tissue specimens were harvested for histological examination. RESULTS: The composite skin graft resulted in less contracture and better elasticity. Compared with group C, the wound contraction rate was lower significantly. Histological examination revealed that there was full differentiation of epithelium, orderly collagen arrangement and intact basement membrane. CONCLUSION: Coverage of wound with composite skin composing heterogeneous (swine) acellular dermal matrix and autologous particulate skin could promote wound healing and improve wound healing quality.
