查询词典 lethal dose

On September 6, 2005, the US Food and Drug Administration licensed the combination tetravalent MMRV vaccine for use in children aged 12 months to 12 years. To prevent measles, mumps, rubella, and varicella, MMRV vaccine can be used instead of trivalent MMR vaccine and monovalent varicella vaccine. To fulfill the recommended 2-dose vaccine policies, the first dose is recommended at age 12 to 15 months and the second at age 4 to 6 years.

The results of surface dose rate determined with lithium fluoride thermoluminescent dosimeter chips in water-organic glass phantom and air had no obvious difference and the surface dose rate and its uniformity,(3.46±0.011) and (0.178±0.15)nGy/h*107Bq were obtained.

用LiF热释光片在水-有机玻璃体模及空气中，分别作125I眼科巩膜敷贴器的表面剂量测定，结果在误差范围内无明显区别，得到的最终表面剂量及其均匀性分别为：(3.46±0.01)、(0.178±0.15)nGy/h*Bq。

Since a recent randomized study showed no dose-response relationship, the target dose in future will be 20mg tid.

由于最近一项研究显示无量-效关系，所以将来的剂量可能是20毫克日三次。

objective to investigate the existence of the erythropoiesis inhibitors.methods the present study included twelve undialyzed esrd patients with anemia.the sera from the uremic patients were added to cfu-e and bfu-e culture in the concentrations ranging from 1.25% to 5%.in vitro cfu-e and bfu-e growth in the presence of sera from esrd patients was compared with in the presence normal human subjects with the use of normal mice bone marrows.results the effects of the sera from uremic patients on cfu-e and bfu-e colony growth in concentrations ranging from 1.25% to 5% were investigated to be dose-dependent.the effect increased with the concentrations increasing of the sera（p＜0.05）.there were not significant inhibitory effect on the cfu-e and bfu-e growth of mice bone marrow in vitro from sera of the normal subjects.conclusion the erythropoiesis inhibitors exist in uremic sera which has a dose-dependent inhibitive effects on the growth cfu-e and bfu-e of normal mice bone marrow cells.

选择12例尿毒症肾性贫血未透析患者为试验组，另选正常健康体检者12例为正常对照组，将实验组、正常对照组血清分别稀释成不同终浓度，采用甲基纤维素细胞培养的方法对小鼠骨髓细胞进行培养，对比不同浓度血清组红系集落形成单位、红系爆式形成单位的集落数。结果在实验组中，与血清浓度为0的浓度组相比，与各浓度组血清共同培养的小鼠骨髓cfu-e和bfu-e的集落数均明显减少，且随血清浓度的增加，小鼠骨髓cfu-e和bfu-e的集落数逐渐减少，各浓度组间差异有显著性（p＜0.05）。结论尿毒症患者血清抑制小鼠骨髓红系祖细胞集落形成，随患者血清浓度的增加，抑制作用增强，具有剂量依赖性。

The HSS action showed a dose-effect manner and this action was proved uneffective with the larger dose of CCl〓.

第三，谷胱甘肽对外源性毒物和内源性代谢产物的解毒起着重要作用。

The HSS action showed a dose-effect manner and this action was proved uneffective with the larger dose of CCl〓.(2) Hepatic histological findings indicated that CCl〓-induced hepatic lesions could been alliviated by HSS.(3) CCl〓-induced reduction of hepatic mitochondrial succinic dehydrogenase activity was restored by the treatment of HSS.

相反，如果CCl〓所用剂量过大，HSS将无抗损伤作用；(2)HSS可使CCl〓损伤肝组织的程度减轻，用肝组织切片可充分证明这一现象；(3)HSS可使CCl〓损害肝细胞线粒体琥珀酸脱氢酶的活性恢复，用组织化学法可得到证实。

The unirradiated and irradiated samples are analyzed by FTIR, SEM, PGC/MS and TG. At the same time, the gas products after irradiation are analyzed by GC/MS. The relationship of gel fraction of irradiated samples in air with the dose and the compression property and stress relaxation ratio along with the dose are determined.

采用傅立叶红外分析仪、扫描电镜、裂解色谱质谱联用仪以及热失重分析仪等对辐照前后的样品进行了分析，同时使用色质联用仪对辐照后产生的气体进行了分析，并且测定了空气中辐照试样的凝胶含量与吸收剂量的关系以及在室温下试样的压缩性能、应力松弛率与吸收剂量的关系。

At the experimental intensity of 20W/cm^2 and in the dose range studied (0.00, 0.24, 0.48, 0.72, 0.96 and 1.20kJ/m^2), both the population number and growthrate was the highest in the control and decreased with the increment of UV-B radiation. In addition, the population number and growth rate of rotifer Brachionus urceus showed a similar tendency of decrease with the dose increase of UV-B radiation. Both of them could be used as an ideal biomarker for the enhancement of UV-B radiation.

实验表明，在本实验辐射强度(20W/平方公分)和剂量范围内（0.24、0.48、0.72、0.96和1.20kJ/平方人公尺）壶状臂尾轮虫的种群数量和种群增殖率均以对照组最高，各UV-B辐射处理组则随UV-B辐射剂量的增大而呈一致性减小，说明该种群的种群数量和种群增殖率随UV-B辐射的增强显示一致性的影响，两者都可以作为大气UV-B辐射强弱的生物指标。

Results With the low-dose scan, The sensitivity and accuracy rates of the detection of nephrolithiasis and ureterolithiasis on the low-dose scan were 100% and 98% respectively.
