摘要: 目的初步探讨人工神经移植物丝素蛋白导管的生物相容性。方法将丝素蛋白导管植入兔子皮下,术后4周、8周、12周、24周取材,切片,HE染色,观察局部组织反应。结果大体观察和组织切片观察,局部组织反应轻,纤维包裹逐渐变薄,丝素蛋白导管至24周完全降解。结论丝素蛋白导管有良好的生物相容性和可降解性,是理想的人工神经移植物。

Abstract: Objective To evaluate the biocompatibility of the silk fibroin-based nerve grafts in vivo.Methods Silk fibroin conduits were subderma implanted,harvested at 4,8,12,and 24 weeks after operation and processed for histologic analysis.Results There was mild inflammatory reaction at the implant sites.Silk fibroin conduits were completely absorbed after 24 weeks.Conclusion Silk fibroin conduit had an excellent compatibility and suitable degradable properties to be used for peripheral nerve regeneration.
