Objective To observe the clinical effect of the human tissue engineered activeskin (ActivSkin) with full thickness on the donor site of the split thickness skin graft. Methods Nine patients with 18 wounds of the donor sites, and every p atient had 2 wounds. The wounds of each patient were randomly assigned to the therapy group and the control group. Autocontrol observation was performed. Nine donor sites of the split thickness skin graft were repaired with ActivSkin in the therapy group. Nine donor sites of the split thickness skin graft were repaired with the vash oil gauze in the control group. The wound pain, the time to complete closure, and the ratio of the complete healing in the ActivSkin therapy gro up was measured and compared with those in the control group. The donor sites of the split thickness skin graft were assessed at 180 days of the follow-up visit . Results The wound pain was obviously reduced after the harvest ing of the skin grafts in the therapy group. The time to complete closure on the donor sites of the split thickness skin graft was significantly shorter in the ActivSkin therap y group than in the control group (9.67±2.92 d vs.16.56±2.96 d, Plt;0.05 ). Both the ratios of the complete healing in the ActivSkin therapy group and the control group were 100%(Pgt;0.05). The subsequent results showed that neit her the blister nor the residual wound occurred with an alleviated scar after the Ac tivSkin treatment. Conclusion ActivSkin can promote wound closure, prevent blister and residual wound, and alleviate scarring on the donor sites of the splitthickness skin graft after the ActivSkin treatment.
