100 mice were randomly divided into high-dose group, middle dose group, low-dose group and the control group. The content of NO in liver, lung, cardiac muscle and skeletal muscle was detected after oral administration of different doses Tibetan Saussurea involucrata Kar. et Kir. water extract for treatment groups and saline water for control group in 24 days respectively.

方法］将100只小白鼠随机分为高剂量组、中剂量组、低剂量组和对照组，连续24 d分别灌服不同剂量的藏雪莲水提取物和生理盐水，然后处死小白鼠快速采取肝、肺、心肌和骨骼肌，测定各组织内一氧化氮的含量。

As compared to thermoluminescent dosimeter, Dose Ace radiophotoluminescent glass dosimeter had more advantages in clinical dose measurement, such as repeatability, suitability, stability, and small effective area. We postulate that radiophotoluminescent glass dosimeter is one of the most useful radiation dose measurement tools in the future.

Dose Ace系统玻璃剂量计与热发光剂量计相较之下，玻璃剂量计具有好的计读值再现性、稳定性、小的有效测读区域、且可重复测读；因此可预见玻璃剂量计在辐射剂量测量方面将占有极重要的地位。

The thermoluminescent dosimeters are widely used for measuring the radiation dose. However, the luminescence centers of thermoluminescent dosimeter are disappeared by reading process, and then repetition of measurement is impossible. Radiophotoluminescent glass dosimeters can be repeatedly read and keep the luminescence centers for a long time. The aims of this study are to develop and characterize the radiophotoluminescent glass dosimeter and measure the clinical radiation dose using Dose Ace system.

热发光剂量计广泛应用於辐射剂量的测量，其缺点为在计读过程中，发光讯号会消失不见，无法重复测读，而玻璃剂量计发光讯号不会因计读过程消失，可重复测读；本研究目的为进行试制玻璃剂量计，分析所试制玻璃剂量计的各项特性，亦使用商业化Dose Ace系统量测临床辐射剂量。

Low-dose MSCT is sensitive and safe in investigating ureterolithiasis. High accuracy for the detection of ureterolithiasis is obtained and the radiation dose is significantly decreased by using low-dose MSCT performed.

低剂量螺旋CT平扫是一种敏感、安全的输尿管结石的检查方法，它诊断输尿管结石能够获得高准确率，并且明显降低对病人的放射剂量，延长了球管的使用寿命。

Methods ①anti-inflammatory trial: 40 rats were randomly divided into control group, high-dose bushenlizhuo capsule group, middle-dose bushenlizhuo capsule group and low-dose bushenlizhuo capsule group(10 rats in each group).the rats in control group were given distilled water, and the rats in experimental groups were given different doses of capsule（4.0、2.0、1.0g/kg）, then enhance the capillary permeability of abdominal skin of rats by using xylic acid,and the od numerical value was detected.

(1)抗炎实验：将40只小鼠随机分为补肾利浊胶囊高、中、低剂量组及对照组各10只，补肾利浊胶囊高、中、低剂量组分别给予相应剂量的补肾利浊胶囊(分别为4.0、2.0、1.0 g/kg)，对照组给予蒸馏水，采用二甲苯酸致小鼠腹部皮肤毛细血管通透性增高，测定光密度值；(2)镇痛实验：40只小鼠分组及给药同抗炎实验，采用腹腔注射醋酸致小鼠出现扭体反应，纪录扭体次数并计算镇痛百分率；(3)抗前列腺炎实验：将雄性大鼠50只随机分为补肾利浊胶囊高、中、低剂量组及模型对照组及正常对照组，各10只。

After twenty-one days, they were challenged by white spot syndrome virus. The mortalities of crawfishes after challenged with WSSV of the same dilutions were negatively correlated with the the dose of Ig-Guard, that is, along with the increase of the dose of Ig-Guard, their mortalities were decline; The LD50 of the immune group was higher than the control group, further more, along with the increase of the dose of Ig-Guard, the effectes were obvious.

注射相同稀释浓度的螯虾，其死亡率与添加Ig-Guard的剂量呈负相关，即添加Ig-Guard剂量越高，其死亡率越低；免疫组螯虾的半数致死剂量(LD50)高于对照组的半数致死剂量，而且其效果随着免疫剂量的增加而越来越明显。

Result: B-2 can increase abdominal cavity macrophage phagocytic activity significantly (p.001) B-1 can increase abdominal cavity macrophage phagocytic activity (high dose of B-1: P.01, low dose of B-1: P.05). Only high doses of S. sphenanthera coarse polysaccharides can increase phagocytic activity (phagocytic index p.05) and show dose-dependent augmentor effects.
