Materials and methods: The composite was respectively prepared by blending Lysine, Histidine, Arginine with PLGA, while the composite respectively prepared by blending Algin, chitosan, NaHCO3 with PLGA as the comparison and the pure PLGA as the control. All composites were degradated in tri-distilled-water at 37℃ for 7 weeks. The degradation property of PLGA with the addition of basic additives was investigated by using gross observation, the pH change of degradation solution and the mass loss ration of the composite.
材料方法:将赖氨酸、组氨酸、精氨酸分别各按5%和10%的比例与PLGA制成复合物,于体外在37℃下在三蒸水中进行降解2个月;通过总体观察、降解液PH的变化、复合物的失重率等指标来考察碱性氨基酸对PLGA体外降解特性的调节作用,同时将碱性氨基酸的调节效果与海藻酸钠、壳聚糖、碳酸氢钠的进行对比。
