Abstract:
Objective To compare the difference of wound healing quality of composite skin grafting consisting of xenogeneic (porcine) acellular dermal matrix (PADM) combined with micro-autograft or split-thickness autograft of skin. Methods Seventy-two Sprague-Dawley rats with full-thickness skin defect on the back were randomly divided into three groups,namely test group I with PADM with split-thickness autologous skin,test group II with HADM with autologous micro- skin and allogeneic skin graft,and control group with autologous micro-skin with allogeneic skin graft to cover the skin defect area respectively. The take rate and the condition of wound healing,and also the rates of wound contraction were calculated. Tissue samples were harvested for histological examination. Results The wound contraction was less in test group I and II than that in control group( P
