摘 要:目的制备壳聚糖与聚乙烯醇纤维膜并研究其体外的生物相容性,为应用于临床提供一定的理论依据。方法利用静电纺丝技术制备壳聚糖与聚乙烯醇纤维膜,通过扫描电子显微镜对其超微结构进行表征,采用溶血实验和细胞毒性实验评价其体外生物相容性。结果通过电纺制备的壳聚糖与聚乙烯醇纤维膜,质地均匀,伴有少量的珠状结构,纤维直径在60-300 nm之间,溶血实验显示溶血率为2.80%,无溶血作用,细胞毒性实验中,纤维膜的细胞增殖度为89.96%,细胞毒性为1级,评分合格,无细胞毒性。结论通过静电纺丝法可成功制备壳聚糖与聚乙烯醇纤维膜,生物相容性较好,有望应用于口腔临床中。Objective To prepare of chitosan/poly(vinyl alcohol) fiber membrane and to explore the biocom-patibility in vitro, in order to provide certain theoretical basis for clinical application. Methods The chitosan/poly(vi-nyl alcohol) fiber membrane was prepared by electrospinning technique. Its ultrastructure was characterized by scan-ning electron microscope (SEM), and its in vitro biocompatibility was studied with hemolysis test and cytotoxicity test. Results The chitosan/poly (vinyl alcohol) fiber membrane prepared was found to have a good appearance and homoge-nous fibers, with a little beads and the diameter of 60-300 nm in average. The hemolysis rate was 2.8%, which means no hemolysis. The cell relative growth rate of the fiber membrane was 89.86%, with the cytotoxicity of gradeⅠ, which indi-cated no cytotoxicity. Conclusion The chitosan/poly (vinyl alcohol) fiber membrane can be prepared by the electrospin-ning technique successfully, with good biocompatibility, which is expected to be applied in oral clinical practice.
