The model of ECV-304 cell oxidative stress injury was established by hydrogen peroxide (H2O2).Then EPZ-contained blood serum was taken as experimental drug. The adherence of monocytes to endothelial cell were measured by method of rose Bengal. The total RNA of cells was extracted. The intercellular adhesion molecule-1 (ICAM-1),vascular cell adhesion molecule-1 (VCAM-1) and MCP-1 mRNA expression in cells were detected by RT-PCR.MCP-1 protein expression were detected by ELISA.

采用过氧化氢建立离体培养的血管内皮细胞(ECV-304)氧化应激损伤模型，取健康大鼠每日灌服不同剂量的鲜姜有效部位(200，400，800 mg·kg-1)或阳性对照药洛伐他汀(40 mg·kg-1)，取含药血清作为受试药物，用孟加拉玫红染色法测定单核细胞与内皮细胞的黏附力；逆转录聚合酶链反应测定细胞内细胞间黏附分子-1(ICAM-1)、血管细胞黏附分子(VCAM-1)以及单核细胞趋化蛋白(MCP-1)的mRNA表达水平；酶联免疫吸附法测定MCP-1蛋白表达水平。

These enzymes are incapable of breaking down or digesting wool,hair or silk fibres which are to them indigestible protein.

这些酶不会降解毛类，毛发及丝类纤维。这些蛋白对于这类酶来说是不可降解的蛋白。

As the only phosphatase regulated by Calmodulin, calcineurin plays an important role in psycological function.

钙调蛋白磷酸酶是唯一一个受钙调素调节的蛋白磷酸酶，有着重要的生理功能作用，然而它的CaM结合区及自抑制区的结构信息却长期处于未知状态。

The IWFs were purified by (NH4)2SO4 precipitation fractionation, and then applied to Sephadex G-75 column. The column eluates were collected separately according to A280 nm and injected into the health wheat leaves to examine the eliciting activities by PAL, PO assays.

IWF经硫酸铵粗沉淀后，将蛋白沉淀用重蒸水重新溶解后进行凝胶过滤柱层析，以280nm紫外吸收检测、收集不同的蛋白峰，分别注射到健康的Thatcher叶片中，以苯丙氨酸解氨酶(phenylalanine ammonialyase，PAL)、过氧化物酶(peroxidase，PO)防卫反应作为评价诱导活性的指标，检测活性成分在各部分中的分布和诱导活性的强弱。

Combined with the test of All〓wden reaction and observation with SEM, the data have proved that protease SZ can digest the protein of epicuticle and then hydrolyzed the cuticle of wool, while the other proteases have no this distinctive effects, although they can confer wool bigger weight loss too. As protease SZ can digest the epicuticle and cuticle, the wool can be confered excellent antifelting property with low tenacity and elongation loss.

本文结合羊毛的阿尔瓦登反应和电镜观察，证明了绝大部分酶制剂由于不具有对羊毛鳞片表层蛋白的水解特性，因而处理后的羊毛不具有良好的防毡缩性能，而SZ酶却可对羊毛鳞片表层蛋白进行水解，进而可以对羊毛的鳞片进行有效的减量改性，使羊毛获得优良的防毡缩性能。
