Biological study of biodegradable Poly(propylene carbonate) Prepared from Copolymerization of Carbon Dioxide with Propylene Oxide. |
초록 |
We synthesized poly(propylene carbonate) (PPC) films by copolymerization of carbon dioxide with propylene oxide. We investigated bacterial and cell adhesion to PPC in vitro, and biocompatibility and biodegradability in mice. Adhesion of human cells (cell line HEp-2) and five bacterial species [Staphylococcus epidermidis (S. epidermidis), Staphylococcus aureus (S. aureus), Enterococcus faecalis (E. faecalis), Pseudomonas aeruginosa (P. aeruginosa) and Escherichia coli (E. coli)] to PPC films was examined. PPC was also implanted subcutaneously in mice to assess biocompatibility by examining tissue reactions around implant sites and to assess biodegradation causing morphologic changes to the film surface. In addition, in vitro oxidative degradation tests were carried out to understand the mechanism of PPC biodegradation in mice. |
