But the plasticization and application of PLA is dramatically influenced by the migration of ATBC. So in this paper PBA as a novel plasticizer is used to plasticize PLA.

本文首次采用PBA作为PLA增塑剂，对比研究发现当增塑质量大于20wt%时，PBA较ATBC具有更高的增塑效率。

Nifedipine was used as the model drug, PLA as the carrier, and poly vinyl alcohol as the stabilizer, respectively.The mechanism of PLA microspheres formation was developed.

载药体系以硝苯地平为模型药物、聚乳酸（poly-lactic acid， PLA）为载体材料、聚乙烯醇（poly vinyl alcohol， PVA）为稳定剂。

The results show that the hydrophilicity of PLA film is improved by introduction amido: the contact angle decreases from 78° to 56° and the free energy increases from 42.7mJ/m^2 to 51.4mJ/m^2. Compared with the control, osteoblast spread out more filopodia after 3 d incubation on amidation surface, and it entered cell division phase more quickly, which indicated that the surface amidation could promote the cell's adhesion and proliferation on the PLA film.

结果表明，酰胺基的引入改善了PLA膜的表面亲水性，其表面水接触角由78°减少到56°，自由能由42.7mJ/平方公尺增大到51.4mJ/平方公尺；与对照组相比，成骨细胞在改性表面培养3d后有大量的丝状伪足伸出，并且较快地进入了细胞分裂期，表明PLA膜表面的酰胺化能够促进细胞的黏附和增殖。

MethodsCaS/PLA/GM implant tablets were made from composite of citrated calcium sulfate and polylactic acid mixed with gentamycin at a certain ratio. According to ISO 10993-1 standards, following biological experiments were performed to evaluate the biocompatibility and safety of the CaS/PLA/GM delivery system, as well as haemolysis, cytotoxicity, pyrogenic, and intramuscular implanting tests.

本实验以已研制的生物可降解柠檬酸化硫酸钙[2]作为抗生素载体，研制新型抗生素释放系统-硫酸钙/聚乳酸/庆大霉素释放系统(calcium sulfate/polylactic acid/genta-mycin CaS/PLA/GM)，对其生物相容性进行评价。

Objective To prepare the sustained-release pellets of Ginkgo leaves sustained-release pellets using the polymerization(PLA-PCL-PLA) of εcyclohexyl lactone polylactic acid as carrier,and test the release rate.

目的利用ε-己内酸酯与聚乳酸共聚改性聚合物(PLA-PCL-PLA)为载体，制备银杏叶有效成分的缓释微丸制剂，并考察其溶出度。

The drug release experiments in vitro indicated that with the increase of PLA molecular weight, the drug release rates decreased. 4ac releasing from 4ac-PLA-NP could be characterized by Weibull's equation. The interaction between 4ac and others compositions was not detected by DSC. The peak position of 4ac in DSC did not changed comparing 4ac with 4ac-PLA-NP lyophilize injection. Thc X-ray result showed that the peak of 4ac-PLA-NP was piled up between 4ac and other compositions.

差示扫描量热分析结果表明药物与各组分之间无明显的相互作用，制成4ac-PLA-NP冻干针剂后，其放热峰主要表现为聚乳酸的放热峰：X-射线衍射结果表明药物与载体间无相互作用，4ac-PLA-NP主要表现为4ac与载体之间的叠加峰；TLC、FT-IR也同样表明药物与载体无相互作用，它们之间是一种物理结合，并未有新物质生成。
