无细胞异体真皮基质在烧伤后整形患者功能部位的应用

AIM:To investigate the effect of allogeneic acellular dermal matrix(ADM) on cograft in joint functional positions of patients with post burn plastic operation. METHODS:9 patients with hypertrophic scar and joint dysfunction after severe burns were used. After pre treating with trypsin and TritonX 100, 13 reticulated ADM were overlapped with autogenous ultrathin split thickness skin grafts(USTS), and were transplanted to the scar excision wounds in the joints of four limbs at the same time. The neighbouring autogenous thin split thickness skin grafts(TSTS) were used as control.RESULTS:The composite skin grafts as well as the controls were all survived. The rejection and hypertrophic scars were not found during (1- 5) years follow up studies. The appearance, fiber and function of composite skin grafts were near to normal skins. CONCLUSION:The ADM could be used to joint functional positions of patients with post burn hypertrophic scars and could produce satisfactory plastic results as dermal substitute.

Acellular porcine dermal matrix produced with different methods and an experimental study on its transplantation to skin wound.]

OBJECTIVE: To observed the effect of healing quality of composite skin grafting consisting of acellular porcine dermal matrix combined with autologous split-thickness skin graft. METHODS: Porcine skin was treated with dispase II/triton X-100 or hyperosmotic saline/sodium-dodecyl-sulfate (SDS) respectively, and acellular porcine dermal matrix I (APDMI) and APDM II were obtained. Sixty-three Sprague-Dawley rats with full-thickness skin defects on the back were separately covered with APDMT + split-thickness autologous skin, or APDM II + split-thickness autologous skin. The quality of wound healing was observed, the rates of survival and contraction of the grafts were calculated, the tissue samples were harvested for histological examination, and compared with that of autologous split-thickness skin graft. RESULTS: The wound healing quality of composite skin I, and II was good. There was no significant difference in the rate of survival and contraction of the grafts between the two composite skin grafting groups. It was indicated by histological examination intact basal membrane. There was no significant difference in the survival rate between composite skin grafting groups and autologous split-thickness skin at the 6 th week after operation, but the contraction rates of the grafts in the composite skin groups were lower. CONCLUSION: Full-thickness skin defect can be healed by covering with acellular porcine dermal matrix produced by two methods combined with split-thickness autolograft, and it can help improve the quality of wound healing.
