A new therapeutic agent for leukemia:clofarabine;

新型抗白血病药氯法拉滨

This article summarizes the process mechanism, pharmacokinetics,pharmacodynamics,clinical studies and safety profile of clofarabine.

氯法拉滨是第2代嘌呤核苷酸类似物,对患有难治性或复发性急性淋巴细胞白血病的1～21岁病人有显著疗效,是近10年来首个FDA批准的专门用于治疗儿童白血病的新药。

Benzoylated clofarabine was achieved by reacting 2-chloroadenine with 1-deoxy-1-.

氯法拉滨是一种核苷类似物，对多种实体瘤均有作用，对急性白血病的治疗尤为有效，是FDA首个专用于治疗儿童白血病的药物。

Diagnose of Large Area Electron Beam with Faraday cup;

法拉第筒用于大面积电子束均匀性诊断

The measurement principle of faraday cup and the measurement error of faraday cup were analysed.

介绍了法拉第筒的测量原理,分析了法拉第筒的测量误差,设计出用于离子推力器束流特性测量的法拉第筒仪器,成功地应用于20 cm离子推力器束流特性的测量。

The apertures of Faraday Cups are covered with Mylar films of different thickness, and then the signal attenuations can be recorded with oscilloscope.

在偏压法拉第筒阵列各个法拉第筒的准直孔前分别覆盖0—6μm厚的Mylar膜,根据不同膜厚对应的信号衰减情况(叠片法),得到了高功率离子束的离子能谱,离子的最高能量>440keV,平均能量约为270keV,能量为200—300keV之间的离子数目最多,碳离子数和90keV以下的质子所占总离子数的组分不多于32%。
