Results: we got the highest 18F-FDG productivity (55%) and radiochemistry purity (93%) with 0.2ml K2CO3, 0.3ml BMI, 0.7ml acetonitrile and TATM 25mg.

结果：采用25mg TATM在0.2ml K2CO3、0.3ml离子液体体积、0.7ml乙腈时获得最高的合成效率(55%)和放射化学纯度(93%)。

Alzheimer′s disease animal models were made by damaging bilateral nucleus basalis of Meynert of elderly rats (20-22 month) with quinolinic acid(150 nmol in 2 μL for each NBM, given d 3 after administration of test drugs). Activity of choline acetyltransferase was measured by radiochemistry assay. One time training passive avoidance step-down and water-maze spatial localization task were used to observe effects of ginsenoside of stem and leaf in combination with choline on learning and memory of AD model rats.

应用喹啉酸（每侧150 nmol，2 μL，给受试药后d 3注射）损毁老年大鼠双侧Meynert基底核制备阿尔茨海默病动物模型，放射化学法测定胆碱乙酰基转移酶活性，一次性训练被动回避跳台实验和水迷宫空间分辨能力测试，观察人参茎叶皂甙和胆碱合用对AD模型大鼠学习记忆的影响。

The produced thorium was radiochemically separated from the mixture of uranium and its reaction products.

用快速放射化学分离技术从铀及其反应产物的混合物中分离出Th同位素。

METHODS The formulation of tetrofosmin and stannous chloride for injection was optimized using orthogonal design with radiochemical purity.

方法以放射化学纯度为指标，选取替曲膦用量、氯化亚锡用量、制剂pH值和氮气保护时间四个因素，每个因素选取三个水平，选用L9(34)表进行正交实验，对注射用亚锡替曲膦的处方进行筛选。
