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。

ABSTRACT Computer tomography is widely applied not only in the medical radiodiagnosis, but also in the industry inspection.

计算机断层成像无论在医学放射诊断方面，还是在工业领域中均有着广泛的应用。

Radiogenic heat, even from a fairly deep-seated uranium orebody, could be measured.

Objective: To evaluate the effects of radiations on thyroid function for the medical radiographer.

目的：了解电离辐射对医用放射工作人员甲状腺功能的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
