In this study, LDL was oxidized by copper ion, 2, 2'-azobis(2-amidio-propane)dihydrochloride or macrophages in the absence or presence of apoH to delineate the correlation between apoH and LDL peroxidation,. It was shown that the formation of thiobarbituric acid reactive substances and conjugated dienes was decreased and the electrophoretic mobility of LDL was reduced in the presence of apoH. It suggests that apoH exerts an antioxidative effect.

为了进一步了解脂蛋白元 H 的表现与低密度脂蛋白氧化之间的关连性，分别以铜离子、 2， 2'-azobis(2-amidio-propane)dihydrochloride (一种可生成自由基的化合物)或巨噬细胞等来氧化低密度脂蛋白，发现在有脂蛋白元 H 的存在下，不论是 thiobarbituric acid reactive substances、共轭双烯的生成以及低密度脂蛋白电泳移动速率，都受到明显抑制。

The effect of controlling microstickies in recycled newspaper pulp and the effect on the resultant paper property of some fixatives,including inorganic polyaluminum chloride,organic polyamine,polydiallydimethyl ammonium chloride,and high cationic starch,were investigated in this paper.

The results available now indicate that glass-like carbon synthesized from phenolic resin is a non-graphitizing carbon, and consists of both sp 2-hybridized carbon atoms that form imperfect graphite structure and sp 3-hybridized carbon atoms that are due to the presence of disordered carbon; and in the fullerene-related structure of glass-like carbon, there exist some pentagons and heptagons carbon rings.

玻璃炭作为一种特殊炭材料已广泛应用于许多领域，其制备、性质、应用以及基本结构的研究已经取得了很大的进展，已有的研究结果表明酚醛树脂基玻璃炭是一种典型的非石墨化炭材料，由 sp2杂化态碳原子和 sp3杂态碳原子组成，且在其类富勒烯结构中存在五元环和七元环。

A normal-phase liquid chromatographic method has been developed for determination of tocopherols and tocotrienols in hull-less barley.

本论文以裸大麦为原料，研究与探讨了生育三烯酚的分析检测、提取分离及对超氧阴离子自由基损伤人脐静脉内皮细胞的防护作用，主要实验结果如下

Moreover, MeJA induced defense genes, such as pathogenesis-related proteins (PR2a), phenylalanine ammonia-lyase, BX9, and TPS. MeJA also increased DIMBOA and Vannillic acid content of leaves and roots significantly but leaf p－Hydroxybenzoic acid concentration was decreased significantly and Protocatechuric acid was produced in roots only.

1MeJA叶片处理能诱导叶片和根系中丙二烯氧化物环化酶基因、糖基转移酶（BX9）基因、苯丙氨酸转氨酶基因的表达，使叶片和根系中丁布含量升高，同时，6μL/L MeJA处理使第二叶中原儿茶酸含量显著降低，诱导根中产生原儿茶酸，使第二叶中香草酸含量和根中未知物质峰面积显著增大。

A series of imides oligomers were synthesized with the phenylethynylphthalic anhydride , nadic anhydride and cyanophthalic anhydride as endcapped agents.

我们以苯乙炔苯酐、降冰片烯二酸酐和氰基苯酐为封端剂合成了一系列的酰亚胺低聚物。
