OBJECTIVE: To prepare cytotoxin/poly lacticoglycolic acid nanoparticles, and to study the general property and drug release in vitro.

目的：制备眼镜蛇毒细胞毒素-聚乳酸-羟基乙酸微球，观察其一般性质和体外释药特性。

The original crystal configuration of KGM was destroyed, and the molecular structure was disordered. The glass transition temperature T(subscript g of TKGM was only 13.14℃, and there's an obvious melting decalescence peak at 102℃, the difference between decomposed temperature and melting temperature is above 200℃. This means that TKGM has a good thermoplasticization property.

结果表明：合成了KGM和乙酸乙烯酯、丙烯酸甲酯的接枝共聚物；KGM原有的结晶结构被破坏，分子结构呈现无序化；玻璃化转变温度T(下标 g仅为13.14℃，且在102.5℃处有明显的熔融吸热峰，分解和熔融温差达200℃以上，具有较好的热塑加工性能。
