In order to isolate the active compounds in ethyl acetate fraction of Psoralea corylifolia L., activity-guided isolation was performed along with chromatographic techniques. Four active compounds were isolated from ethyl acetate fraction and identified by their NMR spectral data and physical-chemical properties. They are corylin and bavachin, which showed stimulating effect on osteoblastic proliferation and differentiation, isopsoralen and psoralen exhibited activity of promoting cell differentiation in some degree.

为了追踪分离补骨脂乙酸乙酯萃取物中的活性成分，本实验采用多种色谱分离技术，以活性测试为导向，结合波谱技术及理化数据，从补骨脂乙酸乙酯萃取物中分离并鉴定了4个活性化合物的化学结构，它们是具有促进细胞增殖和分化作用的补骨脂异黄酮和补骨脂二氢黄酮，对细胞分化有一定促进作用的异补骨脂素和补骨脂素。

This dissertation, based on (1) field investigations and observation along Jiangsu coastal environment (including: sea bottom and tidal flat sediment sampling, water depth, salinity, current velocity and direction, core drilling and so on);(2) integrative laboratory analyses of micropalaeontology, sedimentology and computer-processed mathematical statistics on over 300 samples and about 100 thousand foraminifera tests, try to find and formulize the relations between foraminiferal thanatocoenose and environment.

本文的写作基础是：通过野外进行的海岸环境调查和测量（主要调查项目有：水深、盐度，流速、流向、含沙量、底质采样、浅地层地震剖面仪探测、潮滩钻孔取样、潮滩探槽的挖掘与沉积物取样、观测等等）取得了环境参数和大量样品；在实验室运用微体古生物学、沉积学、数理统计与计算机分析相结合的方法，对所采集的现代表层沉积物和钻孔岩芯样品共计三百多个进行了分析研究，鉴定统计有孔虫标本十万余枚，研究有孔虫埋葬群特征与环境参数之间的定性-定量关系。

The results show that the complex ［Ru2］2+ intercalates into the DNA base pair via the intercalative ligand.

结果与结论所合成的配合物结构得到确证，该配合物与DNA之间通过插入作用结合。

The results show that the complex [Ru2](superscript 2+) intercalates into the DNA base pair via the intercalative ligand.

The absorption spectrum of the inclusion complex was decreased and shifted toward long waves in the presence of DNA, confirming the intercalative interaction ofβ-CD-TH with DNA.

可见吸收光谱实验的结果是DNA与硫堇包合物之间的嵌插结合作用使包合物的最大可见吸收峰红移、吸光度降低。

The ratio of free Mit content to total Mit content in IM was 1. 1%, and that in ISM was 4. 7%. Because of its higher drug conjugation rate and good solubility, ISM was select to carry out further investigation. The lyophilized powder of solution type was prepared by using 3% mannitose as the supporting agent with ISM content of 1mg per bottle, whose comprehensive properties were evaluated. The preparation, having hygroscopic property, should keep airtight storage.

选择药物结合率高且偶联物水溶性好的ISM，以3％甘露醇为冻干保护剂，将偶联物制成了溶液型冻干粉针剂，剂量每瓶1mg，并进行了制剂综合性能评价；本制剂有一定吸湿性，应密闭贮存；4℃贮存3个月后制剂稳定性良好，制剂中胰岛素仍保持生理活性，而25℃贮存3个月后胰岛素活性有所降低，所以制剂应低温保存。

DSC and WAXD studies showed that the block copolymers were meltable, and due mainly to the flexible nylon6 segments.

采用DSC热分析的方法，结合WAXD，研究发现，所合成的嵌段共聚物具有可熔融的性质，主要的转变来自柔性的尼龙链段；通过对聚合物空间立体结构的改造，分子链中间位结构的引入以及两嵌段组分分子间和分子内的相互作用强烈影响嵌段共聚物的结晶行为，使结晶更不完善，晶体结构更为疏松，自聚集倾向在很大程度上得到抑制。

N -(4-vinyl)benzylimidazole and its copolymer with octyl methacrylatewere synthesized and characterized,and oxygen—binding properties of cabaltporphyrincomplexes with imdazole ligands were studied.
