Using HPLC separation and receptor binding assay, the present study demonstrated that the principle in the water extract of Huangqin acted on the BDZ binding site was not baicalin, wogonin or chrysin. In vivo study, WEH had no significant effect on pentylenetetrazol-induced clonic seizures in mice, although it could inhibitmaximal electroshock-induced tonic seizures with an ED50 of 3.6g/Kg.

The results show that the introducing of multivinyl monomer and CaCO3 can slow down polymerization rate to different extent.Using 1％～5％ trimethylolpropane trimetbacrylateor divinyl benzene,tight encapsulation of CaCO3 can be realized and beyond 94％PS cannot be extracted. The amount of crosslinker or emulsifier should be accommodated when the load amount of CaCO3 is increased.CaCO3 content in the product increases consequently with the increase of the loaded amount of CaCO3,which can be known from FT-IR and TGA.TEM observations reveal that when the load amount of CaCO3 is 14.8％,most CaCO3 particles are encapsulated and each latex particle contains one CaCO3 particle.Composite particles have well-defined core—shell structure and the thickness of polymer shells is around 10 nm.However,the thickness of polymer shell decreases and many free CaCO3 particles appear when the load amount of CaCO3 reaches 29.3％and 58.7％,respectively.

结果表明，多乙烯基单体以及碳酸钙的引入会使聚合反应速率有不同程度的降低；使用1%～5%的TMPTMA或DVB，可实现PS对碳酸钙颗粒的牢固包覆，不可抽提的PS达94%以上；当碳酸钙用量改变时，需要适当调整乳化剂和多乙烯基单体的用量；IR和TGA的结果表明，随着碳酸钙用量增加，产物中的碳酸钙含量也相应增加；TEM照片和计算结果显示，当碳酸钙用量为14.8%时，绝大部分碳酸钙颗粒被包覆，且基本上每个乳胶粒中包覆一个碳酸钙颗粒，复合粒子具有清晰的核壳结构，壳层厚度约为10 nm，而当碳酸钙用量增加到29.3%和58.7%时，壳层厚度减小，并且出现较多裸露的碳酸钙颗粒。

After selective extraction, the cyst wall of two kind of resting cysts displayed a filament network. In the resting cysts of Tachysoma pellionella and Euplotes encysticus, the filament was located in mesocyst and endocyst respectively. On the other hand, a special filament scaffold region was observed below the cyst wall in two kind of cysts. Compared with the true IF which was located in central part of cyst, the filament of this region was net as well as uniform, and no any cytoplasm residue can be seen in this region. In the resting cyst of Euplotes encysticus, a filamental boundry which partitioned the special filament scaffold region and the true IF region was observed.

两类休眠包囊的包囊壁经生化分级抽提后均显示纤维结构，急纤虫休眠包囊中纤维定位于中间层，包囊游仆虫休眠包囊中纤维定位于内层壁；其次，在两类休眠包囊的包囊壁下，相当于细胞质表质层的位置，均有一个特殊的纤维网络区，与细胞质深层的网络区相比，此部分的纤维纯净、均匀，未见附着细胞器及细胞质残留物，在包囊游仆虫休眠包囊中此纤维网络区与真正的细胞质纤维网络之间由纤维构成的界膜隔开。
