CD62p reexpression rate induced by thrombin was 50.88% and PAC1 reexpression was 54.55%. It is concluded that the ability of recovered lyophilized platelets added with reversible activationinhibitors, DMSO and trehalose to aggregate and coagulate has showed no significant difference as compared with FPRP. The reversible activationinhibitors can decrease CD62p expression of lyophilized platelets, and may enhance their survival ability and prolongate survival time. Therefore the efficiency of lyophilizing platelets can be improved based on this freezedrying procedure.

添加血小板可逆性激活抑制剂，海藻糖和DMSO后的冻干血小板，其聚集活性和促凝血功能与新鲜血小板无明显差异，血小板可逆性激活抑制剂降低了冻干血小板的CD62p表达，增强了冻干血小板的生存能力，因而延长了其生存时间，因此可以该冻干方法为基础进一步提高冻干保存血小板的效率。

The experiment result demonstrates that luohanguo has a lot of pharmacody functions, for instance:resisting thrombus form、repelling blood platelet conglomeration、falling blood fat、contradicting cruor、promoting blood circulation and absorbing clots, and so on. They provided preliminary scienced reference for empoldering and applying luohanguo flavone in the future. Pharmacody functions in other faces still need to research furtherly .

药理结果表明罗汉果黄酮具有一定的抗血栓形成、抗血小板聚集、降脂、抗凝血等活血化瘀作用，为将来罗汉果黄酮的开发应用提供了初步科学依据，对于罗汉果黄酮的其他方面的药理作用还有待于进一步研究。

When both of them are present, the dispersion forms sterically stable state of strip structure.

TME表明，蒙脱土分散体系中加入 KCl使得蒙脱土颗粒聚集，而聚乙二醇导致经微絮凝；二者同时加入，体系形成细枝条状的空间稳定结构。

There were two kinds of pores in the materials which were proved to be packed ordering and disordering respectively. The former was formed by the templating function of surfactant micelles and the latter was considered to be the inter-particle pore that formed by the aggregation of colloid particles during the sol-gel process.

材料中两种类型的孔道分别呈有序排列和无序排列的特征，前者是由表面活性剂胶束的模板作用在胶体颗粒内部的造孔作用形成的，而后者则是在溶胶-凝胶过程中胶体粒子之间发生相互聚集而形成的颗粒间孔。

METHODS Acute incomplete ischemia was induced by ligaturing bilateral carotid arterise and cutting heads in mice, the survival time and asthmatic time were observed; the coagulation timewas measured by sheet glass method,and the blood viscosity was also assayed; the platelet aggregation induced by collagen were studied by turbdimetry in vitro.

采用结扎小鼠双侧颈总动脉造成急性不完全性脑缺血模型，观察平均存活时间；另取小鼠断颅后测定断颅喘息时间；采用玻片法，观察胡芦巴总皂苷对凝血时间的影响；采用比浊法；观察其对体外血小板聚集率的影响，并测定全血粘度。

Results il lustrated that the size of SnO2 crystal particle prepared with sol- gel method is owing to nanometer-size.

结果表明，溶胶-凝胶法制备的电极为纳米涂层电极，表面裂纹较少，晶体发育完全，有利于SnO2， Gd2 O3和吸附氧的表面聚集，进而提高了电催化电极的性能。

Results showed that HOmg inclusion bodies of recombinant pThr-2 were overproduced in E.coli BL21 (DE3) per liter broth, which increased about 40%.

同时也进一步验证了PNIPA凝胶协助复性主要是通过抑制蛋白质相互间的聚集反应来实现的。

He results show that the virus regained infectivity, and the tannins did not direct viricidal effect. Tannins extracted from Polygonum perfoliatum or Archontophoenix alexandrae seeds showed strongly anti-TMV activities separately. TMV virions seems to be aggregated when TMV incubated with the tannins by electron microscope. It seems that TMV coat protein bind to the tannins based on PAGE. Tannins did not reduce infectivity when applied either before or after TMV inoculation. It is proposed that tannins extracted from the 11 species inhibited TMV by binding with TMV coat protein to interfere with recognition site essential for viral coat protein. Tannins extracted from Euphorbia hirta, P. perfoliatum, P. cuspidatum reduce infectivity when applied immediately in N.

MV分别与这11种植物单宁混合后，通过透析除去单宁后，可恢复大部分侵染力，表明单宁对病毒粒体并无直接毒害作用；TMV与杠板归和假槟榔种子中提取的单宁分别混合后，电镜下观察粒体呈现明显的聚集现象；TMV外壳蛋白分别与这两种植物单宁混合后，聚丙烯酰胺凝胶电泳中CP泳带滞后；单宁在病毒接种前施用未降低TMV对叶片的侵染能力；这些结果表明植物单宁对TMV抑制作用可能是单宁与TMV-CP结合影响病毒对叶片侵染位点的识别而降低TMV侵染性，而这种结合是可逆的。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
