Result: All the basic additives investigated in the experiment showed good potential to relieve the level of acid collection in the course of PLGA degradation. Among those, the relieving ability of NaHCO3 was in the top, basic amino acid in the moderate, while Algin and chitosan ranked lower. 5% addition of Lysine produced a best outcome.

结果：各种碱性添加剂都有一定的缓解酸度的能力， NaHCO3的缓解能力最强，海藻酸钠和壳聚糖的缓解能力较低，而碱性氨基酸的缓解能力适中；赖氨酸为5%时的添加量时能够得到较佳的综合调节缓解效果。

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。

Key words: applied chemistry; L-lysine; anisaldehyde; schiff base; Cu complex; fluorescence capacity

关键 词：应用化学；L-赖氨酸；茴香醛；席夫碱；铜配合物；荧光活性

In the following chart, the foods at the top of the list have higher lysine to arginine ratios.

在下面的图表，在列表顶部的食品有较高的赖氨酸精氨酸比率。

The eukaryotic translation initiation factor 5A (eIF-5A) is a small acidic protein (18k Da), widely presents in all organisms from archebacteria to mammals but not in eubacteria, with highly conserved sequences. eIF5A is unique in that it is the only protein known to contain the unusual amino acid residue hypusine (hydroxyputrescine-lysine), which is essential for eIF5A function and is formed by post-translational modification of a specific lysine residue.

真核生物翻译起始因子5A(eIF5A)是一个分子量约18 kDa的酸性蛋白，其序列从古细菌到哺乳动物高度保守，并广泛存在于各种真核生物细胞中。eIF5A是迄今为止唯一一种已知含有特殊氨基酸残基hypusine的蛋白质。hypusine是一种蛋白翻译后修饰产物，它的形成对eIF5A的功能完整至关重要，相关的研究结果表明hypsine在控制细胞周期循环的过程当中扮演着一个重要的角色。

Methods: Using GV1 and GV2 targetable non-viral vectors, the influences of the poly-L-lysine and protamine on in vitro gene transfer efficiency and the course of gene expression were observed. Results:β-galactosidase was expressed at intermediate level (50%) in A375 cells using a complex containing either protamine or poly-L-lysine.

目前，大部分受体介导的靶向性非病毒载体都利用多聚赖氨酸作为骨架分子来包裹DNA形成复合体，并在实验室研究中取得了较好结果，但由于多聚赖氨酸的临床安全性未知，难以应用于临床研究。
