抑制白色念珠菌用载氟康唑明胶纤维支架的制备及表征
|
Abstract:
摘要 目的:制备载氟康唑明胶纤维支架,作为抑制白色念珠菌生长的新型制剂,探讨其理化性能及生物性能。方法:采用静电纺丝方法制备载氟康唑明胶纤维支架,在扫描电镜下观察其形貌表征;通过体外降解实验测试其稳定性;紫外分光光度检测氟康唑释放量;细胞黏附实验观察其黏附性;MTT检测生物安全性;体外培养白色念珠菌测试其抑制白色念珠菌性能。结果:载氟康唑明胶纤维支架具有纳米级纤维直径,呈交错的三维网络结构,5 d时体外降解量约为10%;细胞存活率高,部分细胞黏附在支架表面,部分伸入其中;氟康唑在6 h内释放较快,此后缓慢释放;支架材料对白色念珠菌具有抑制作用。结论:载氟康唑明胶纤维支架的稳定性、黏附性及生物安全性好,药物释放量大而持久,抑制白色念珠菌性能优异
