In this dissertation, firstly, the conditions of isolation and purification of specific toxin fractions produced by Exserohilum turcicum has been studied, and a high-efficient method has been established;secondly, the toxins were analysed by UV-Vis spectrophotometry;then the effect of specific toxin on death rate of corn leaves protoplast was studied by FDA as a tinct reagent;finally, using ANS as a probe and SDS-PAGE to study the membrane protein of the corn leaves with Htl gene. In a word, the aim of the research is to search some existent evidences of the toxin binding site on protoplasmic membrane, and provide proofs for nosogenesis of specific toxin in terms of cytology and the molecular biology.

本研究对玉米大斑病菌1号小种毒素的特异性组分进行分离，建立了高效的特异性毒素分离纯化方法，并对其进行了紫外波谱分析；用荧光素双醋酸酯染色法，测定了毒素特异性组分对原生质体死亡率的影响；进而用1-苯胺基-8-萘磺酸荧光探针标记法和SDS-PAGE电泳法对特异性毒素组分与Htl基因玉米细胞互作过程中的质膜蛋白进行了研究，旨在证明Htl基因玉米细胞质膜上存在特异性毒素组分结合蛋白，为从细胞和分子生物学角度阐明毒素的致病机理提供证据。

Results: Low-dose TSN had no obviously influence on the electrophysiology of rabbit?

目的：研究丹参酮Ⅱ-A磺酸钠对兔在体心室电生理及实验性心律失常的影响。

The behavior of hydrophilic association of sulfonated SEBS ionomers with different counterions in nonpolar solvent was studied by viscometry and dynamic light scattering presenting quantitative measurements of the associated aggregates.

用动态光散射和粘度法表征了基于SEBS的不同配对离子的磺酸离聚物在非极性溶剂中的缔合行为，给出了缔合物存在的证据和缔合物尺寸的定量数据。

The existing form of boron on the rubbing surfaces is sodium metaborate which can be dissolved in water. The hydration water of so- dium metaborate can reduce the aiitiwear function on Four-ball Machine but enhance its antiwear ability on Timken Tester. The study also revealed that sulfonate dispersant Can reduce the antiwear function of sodium metaborate while succinimide dispersant enhance its antiwear ability.

结果表明，含偏硼酸钠的白油能在摩擦表面形成含偏硼酸钠的表面膜而具有较好的抗磨性，硼在摩擦表面膜中以偏硼酸钠的形式存在，钠和钙的石油磺酸盐型分散剂会降低偏硼酸钠的抗磨性，而丁二酰亚胺类分散剂则能提高其抗磨性。

Meanwhile, several physicochemical descriptors of xanthone molecules were calculated by using quantum chemistry method.

同时，运用量子化学计算了山酮分子的物化参数，并选择相互作用能、疏水常数(log P；其中P为正辛醇-水分配系数)和山酮分子总能量作为分析结构-电泳迁移定量关系的物化参数，用以研究分离机制及在毛细管区带电泳分离中山酮类化合物与β-CD 和磺酸化β-CD间的分子识别过程。

Meanwhile, several physicochemical descriptors of xanthone molecules were calculated by using quantum chemistry method. Among the physicochemical parameters, interaction energy, the logarithms of octanol-water partition coefficient and total energy of xanthone molecules were selected to investigate the separation mechanism and describe molecular recognition process between the xanthones and the CDs in CZE by means of quantitative structure-electromigration relationships.
