摘要
蚕丝丝素膜是弱两性天然高分子荷电膜,用丝素膜作载体,固定抗肿病药5-氟尿嘧喧,并探索其在pH=3、7、9,25℃下的缓释性能。结果表明:适量的5-氧尿嘧啶能够固定在丝素膜上,且经过丝素涂层保护,5-FU释放速率变慢,释放时间可以延长;在酸性条件下缓释效果好。
Researches the controlled release per formance of 5-FU fixed on silk fibroin membranewith the conditions of pH3, 7 or 9 at 25℃. Concludes that release rate of 5-Fluorouracil fixed on silk fibroin becomes slower, especially under acidic condition.
