摘要
This study prepared a composite scaffold composed of curcumin and poly(epsilon-caprolactone)-poly(ethylene glycol)-poly(epsilon-caprolactone) (PCL-PEG-PCL, PCEC) copolymer using coelectrospinning technology. Incorporation of curcumin into the polymeric matrix had an obvious effect on the morphology and dimension of PCEC/curcumin fibers. The results of in vitro anti-oxidant tests and of the cytotoxicity assay demonstrated that the curcumin-loaded PCEC fibrous mats had significant anti-oxidant efficacy and low cytotoxicity. Curcumin could be sustainably released from the fibrous scaffolds. More importantly, in vivo efficacy in enhancing wound repair was also investigated based on a full-thickness dermal defect model for Wistar rats. The results indicated that the PCEC/curcumin fibrous mats had a significant advantage in promoting wound healing. At 21 days post-operation, the dermal defect was basically recovered to its normal condition. A percentage of wound closure reached up to 93.3 +/- 5.6% compared with 76.9 +/- 4.9% of the untreated control (p < 0.05). Therefore, the as-prepared PCEC/curcumin composite mats are a promising candidate for use as wound dressing.
