In this research, the activities of CWDE were measured by saccharifying according to the theory that red-brown amino compounds were produced when 3, 5-dinitro salicylic acid and aldehyde were heated together. And the testing conditions were made clear. The activity of Cx should be tested with optimal temperature of 50℃, optimal pH of 4.8, incubation time of 30 min, and optimal substrate of 0.6% CMC-Na. Due to the heat-libality, Cx should be sterilized more than 10 min. The testing conditions of the activity ofβ-G were almost the same with Cx except the substrate of 0.5% salicin and the sterilization time of more than 15 min.

This paper introduced a single antioxidant extraction system--5% sulphosalicylic acid which could extract and assay ASA/DHA and GSH/GSSG simultaneously. Through analysis of kinetic curve of DTNB-GR recycling, the suitable time parameter was selected for the measurement GSH/GSSG. This system made the extraction of antioxidant quick and easy, and enhanced the accuracy, reproducibility and comparability for the antioxidant measurement through it compared to original method of extraction and measurement.

文章介绍了在一个单一提取系统—— 5 %磺基水杨酸中同时提取并测定了抗氧化剂 ASA/DHA和 GSH/GSSG，通过 DTNB— GR循环的动力学分析固定了 GSH/GSSG测定的最佳时间参数；通过与原提取和测定方法的比较，此法对于测定抗氧化剂有很好的准确性、重复性和可比性，使抗氧化剂的提取和测定变得简便快速。

Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.

结果 生理盐水组，2mg／kg组，10mg／kg组PO_2值依次提高(p＜0.01)，脑皮质血流量依次提高(p＜0.01)；脑血流速度依次减低；脑梗死体积依次减少(p＜0.01)；同时在测定的时间段里PO_2和脑组织血流量值与时间成正相关(p＜0.01)；脑梗死体积和脑组织血流速度值与时间成正相关(p＜0.01)。E一选择素在脑缺血再灌注损伤中表达的实验研究中文摘要结论E一选择素能增加脑缺血再灌注损伤的脑组织氧饱和度，脑血流量，减低脑血流速度；减少脑损伤体积；从而保护了脑缺血再灌注损伤的脑组织。

Meanwhile or 24 h later, 316 mg.l-1 sod was added to the culture to act for 24 h, and then, the intracellular reactive oxygen species, apoptosis ratio and expressions of mutant p53 and c-fos protein of hela cells were determined. results the production of ros and the apoptosis of hella cells increased as the action of ddp and adm continued within 24 h, but vp-16 failed to produce such effects.
