Several coterminous bands could be observed by PAGE of natural Eisenin Ⅰ and several coterminous peaks of Eisenin Ⅰ were also detected with MALDI-TOF-MS when the molecular weight of three main peaks are 24, 645, 25, 052 and 25, 281, separately. The amino acid composition of Eisenin Ⅰ(pI. 8) is specilized with high content of acidic amino acids and low content of alkaline amino acids; At the same time, the content of Ser and Thr are quite high and that of Lys, Met, Phe and Trp are quite low. Eisenin Ⅰ is highly homologous with serine proteases. Then, by fibrin plate assay, Eisenin Ⅰ was identified to be a plasmin and also a plasminogen activator, and the fibrinolytic activity was inhibited by PMSF (an inhibitor of serine proteases).

赤子素Ⅰ氨基酸组成特点为高的酸性氨基酸和低的碱性氨基酸含量，且Ser、Thr含量高而Lys、Met、Phe和Trp含量很低；等电聚焦电泳测得其等电点pI.8.N端序列比较结果显示赤子素Ⅰ与丝氨酸蛋白酶类高度同源，纤维蛋白平板法测得赤子素Ⅰ同时具有纤溶酶和纤溶酶激酶活性；通过PMSF对赤子素Ⅰ纤溶酶活性的抑制实验证明，赤子素Ⅰ属于丝氨酸蛋白酶类。

概述了饮酒后酒精在体内的代谢过程及代谢酶类，酒精对人体造成的伤害；中草药解酒药目前的发展状况，并对解酒药的研究发展进行了展望。

From the results of our studies we deduced that sucrose itself in the pith tissue of corn stalk could rule as a represser in someway to suppress the pathogen producing enzyme or toxin which can destroy host cells, or it could destroyor inactivate the enzyme produced by the pathogen, or it was not suitable for toxin surviving in it.

同时，从研究结果我们推断蔗糖本身可能具有阻遏镰刀菌产生酶类或毒素作用，病菌在侵染抗病品种过程中可能因寄主组织中蔗糖含量高，而导致病菌产生的可破坏寄主细胞组织的酶类受到阻遏或活性受到钝化；或者蔗糖不利于致病菌毒素的存活。

The research presented here is aimed at exploring the effect of DTT on the in vitro fibril formation of hen egg-white lysozymes with four disulfide bonds. In this work, we specifically addressed the effect of DTT concentration under different incubation temperatures on the hen lysozyme structure and fibril formation, the effect of addition of DTT at later time points on the amyloid fibrillization of hen lysozymes, and the effect of concentration ratio between reduced and oxidized forms of DTT on the fibril formation of lysozymes.

本研究以具有四对双硫键的母鸡蛋白溶菌酶为蛋白质模式系统，在含盐类之酸性溶液环境下诱导生成类淀粉纤维，再配合二硫代苏糖醇破坏溶菌酶中的双硫键，探讨：（1）不同温度下加入不同DTT浓度对溶菌酶类淀粉纤维形成之影响，（2）不同生长时期加入DTT对溶菌酶类淀粉纤维形成之影响，（3）不同比例之DTT和氧化态DTT浓度对溶菌酶类淀粉纤维形成之影响。
