青蒿

Artemisinin is made from the sweet wormwood plant found in China and Vietnam.

青蒿素是从在中国和越南发现的一种叫青蒿的植物中提取出来的。

They placed genes from the wormwood plant into a yeast organism and got it to produce large amounts of artemisinic acid.

他们把青蒿的基因放置到一种酵母的生物体内，并让它生产出大量的青蒿素酸。

FT-Raman, normal Raman spectra of artemisinin in solid state and surface-enhanced Raman scattering spectra of 1 ?10-5 mol/L artemisinin aqueous solution were recorded. 1756 Cm-1 hexat. lactonic ring vibration which was shown strong in FT-Raman and normal Raman spectra disappeared in SERS spectra. This phenomenon appeared to result from the broken of lactonic ring.

本文对固态青蒿素的FT-Raman光谱和普通Raman光谱以及低浓度(1×10^-^5mol/L)青蒿素水溶液的表面增强Raman散射光谱进行了检测，着重观察了1756cm^-^1六元内酯环振动谱带，发现其在FT-Raman和普通Raman光谱中表现为强振动，而在SERS光谱中此振动谱带消失，说明分子内酯环发生了破裂。

AIM: To investigate the effects of artemisinin on apoptosis and differentiation of classic human acute monoblastic leukemia cell line U937 and to study the possibility of treatment of leukemia with artemisinin.

目的：通过青蒿素对经典人白血病细胞系U937的作用研究，探索青蒿素治疗白血病的可能。

He says artesunate and mefloquine could have a use in places like Eastern eastern Africa where there are high level levels of resistance to several drugs. The Drugs for Neglective Disease Neglected Diseases Initiative began in two thousand three. It was established by the * institute Pasteur Institute and Doctors with Without Borders along with form four publicly supported research organizations.

目前，在非洲，有两种重要的使用青蒿琥酯与其他药物的治疗方法，他说青蒿琥酯与甲氟喹可以用于像东非那样有高抗药作用的地区。2003年被忽略疾病研发药物计划开始，由Pasteur研究所与无国界医生及其他四个公共支持的研究组织成立。

And then,the soluble target protein was purified with Ni-NTA column,and its C-terminal was sequenced with mass spectrum analysis.13 amino acids of C-terminal is identical to the Plasmodium falciparum TCTP when blasted in GenBank. Plasmodium falciparum ; Translationally controlled tumor protein ; Cloning expressing

虽然报道认为TCTP具有钙结合、金属内环境稳定、细胞内信号传导、作为IgE依赖性组胺释放因子、作为青蒿素类药物受体蛋白(Bhisutthibhanet al。，1998)和在约氏恶性疟原虫青蒿类药物抗性系中过表达等功能，但其具体生物学功能尚待进一步研究阐明

Extraction rate of artemisinin increased obviously with the decrease of dielectric constant of the mixed trichloromethane and dichloromethane, which was opposite to the results of mixed solvent of hexane and cyclohexane.

用正己烷、环己烷以及它们的混合溶剂作溶剂时，青蒿素的提取率随着溶剂的介电常数的增大而增大，而用二氯甲烷、三氯甲烷以及它们的混合溶剂作溶剂时，青蒿素的提取率随溶剂的介电常数的增大而减小。

To expand the usage dextrin（I3-CD） was prepared of artemisinin in animals, the inclusion complex of artemisinin with β-cyclo- according to the method we had established. The chemical characterization of the inclusion complex of Art with β-CD was identified by XRD and ^1HNMR in this study.

为了拓宽青蒿素在动物中的应用，扬州大学兽医学院临床兽医实验室制备了青蒿素-β-环糊精包合物，利用X射线粉末衍射和核磁共振氢谱（^1 HNMR）技术对该包合物的表征进行了鉴定。

A theoretical study on geometric structure of the Qinghaosu molecule has been Carried out by ab initio method of the Quantum Chemistry.

文章用量子化学从头算法，研究了青蒿素分子的几何结构，结果表明青蒿素分子的构型、键距、键角、二面角C1-O24-O23-C20等参数与X—射线分析测定值十分接近。

Methods A modle of DTH induced by dinitrofluorobenzene in mice was established and the effect of various concentrations of Qinghaosu, FK506 ,FK506 combined with Qinghaosu on DTH response were observed.

通过建立小鼠DTH模型，灌胃给药，给予不同浓度的青蒿素、FK506及青蒿素与FK506联合用药，观测其对小鼠DTH的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
