摘   要：

A chondroitin sulfate zinc(CSZn)complex was prepared by an ion-exchange method.The purified product was characterized by energy-dispersive X-ray spectroscopy,high-performance chromatography,elemental analysis Fourier transform infrared spectroscopy,inductively coupled mass spectrometry,and nuclear magnetic resonance spectroscopy.The CSZn demonstrated antibacterial activity against Escherichia coli and Staphylococcus aureus and satisfied MTT cell viability(NIH3T3 fibroblasts)at <50 μg/mL.RT-PCR demonstrated significant promotion by CSZn of fibroblast growth factor beta(p-FGF),collagen III(COLIIIal),vascular endothelial growth factor(VEGF)and reduction of cytokines IL-6,IL-1β & TNF-alpha.An in vivo rat full-thickness wound healing model demonstrated significant wound healing of CSZn relative to controls of saline treatment,zinc chloride treatment and chondroitin treatment.CSZn has demonstrated promising antibacterial and wound healing properties making it deserving of consideration for more advanced wound healing applications.
