查询词典 lethal dose

Methods: 50 normal Wistar male rats were randomly divided into five geoups: the sham operated group, injury model group, shenjindan capsule treat group, high dose and low dose group (duzhongyaotong pill treat, D and E)(n=10each). Autogenous nucleus pulposus was removed from the coccygeal vertebral and placed into the back of left L5~6 nerve root, The modle of the non-compressive nucleus pulposus protrusion was created by transplanting autogenous nucleus pulposus in the back of left L5~6 nerve roots. At tow weeks, the SP in dorsal root ganglion was determined by immunohistochemistry.

取健康Wistar大鼠50只，随机分为假手术组、模型组、对照组、高剂量组（D组、腰腿理痛散高剂量组）、低剂量组（E组、腰腿理痛散低剂量组），每组10只，将大鼠自身的尾椎髓核取出移植于左侧硬膜外腔L5、L6神经根背侧，造成非压迫性大鼠自体髓核移植硬膜外模型，通过免疫组化的方法测定大鼠2周时DRG中CGRP的变化。

The dose of the craniospinal irradiation was 36Gy and the total posterior fossa dose was 54Gy.

全脑全脊髓剂量36Gy，后颅窝局部加量至54Gy。

Different treatment regimens had been designed according to different classification.②Properly combined chemotherapy protocols reduced therapy intensity and decreased drug toxicities to patients with standard risk ALL.High dose methotrexate,instead of craniospinal radiation,had become effective phylaxis,and decreased the incidence of extramedullary relapse and CNSL (if indispensably,radiation dose was reduced).This measurement reduced radiation chemotherapy long term side effects and improved survival quality.

化疗方案合理组合在保证疗效的同时对ALL后期治疗降低强度，减少药物毒性，同时改进了庇护所预防措施———采用大剂量氨甲蝶呤，大大减少了髓外复发，使相当一部分患儿放弃以往颅脑预防性放疗，即使需要放疗者也降低了剂量，从而减少放化疗远期毒副作用，提高了生存质量。

In commonly cribble and ultra-fine powder group, heavy, middle and slight dose groups were included. Every heavy, middle and slight dose groups mice were administered with the pulyis by gavage every day at 0.6mL, 0.4mL, 0.2mL and every NS group mouse were ig 0.4mL NS every day.

低、中、高剂量组小鼠分别灌服1∶1的&促免散&粗粉、微粉煎液0.2mL/只/天、0.4mL/只/天和0.6mL/只/天，生理盐水对照组小鼠灌服生理盐水0.4mL/只/天，共灌药6天。

Lower dose of antivenom recommended by the poison control center is probably as effective and safe as higher dose used in the surgical group for the treatment of crotaline snakebites.

因此毒药物防治谘询中心所建议的抗蛇毒血清治疗剂量，就现有证据而言，应该与较高治疗剂量的抗蛇毒血清一样有效。

3NE、MTT、LDH、ET-1、ICAM-1 and Tie-2experiment show: in the process of oxygen glucose deprivation/reoxygenation ,BMEC have subjected great damagement, I/R groups have significant differences compared with NC groups (p.05);polymorphonuclear leukocyte can aggregrate this injury, I/R+PMN groups have significant differences compared with I/R groups (p.05); after Sivelestat Sodium treatment, the effect of I/R injury has been decreased, I/R+PMN+Siv groups have significant differences compared with I/R+PMN groups (p.05), and NE、MTT、LDH experiment show that the three dose groups there was a significant dose-effect relationship.

3测定NE、MTT、LDH、ET-1、ICAM-1、Tie-2 mRNA均显示：氧糖剥夺/复氧复糖过程能对BMEC造成损伤，I/R组与NC组比较有明显的统计学差异(p.05)；中性粒细胞能加重对BMEC的损伤，I/R组与I/R+PMN组之间比较亦有统计学差异(p.05)；西维来司钠处理后，血管内皮细胞的损伤明显减轻，I/R+PMN组与I/R+PMN+SIR组比较有统计学差异(p.05)，并且NE测定以及MTT、LDH实验提示在西维来司钠三个剂量组之间存在明显的量-效关系，其对BMEC的保护作用有剂量依赖性。

KGy dose of γ-irradiation decreased content of vitamin B1 significantly and did not had a significant effect on the content of vitamin E, protein, fat, amino acid and unsaturate fatty acid. The results of x-ray diffract grams revealed that the relatively diffraction intensity tended to decrease and the diffraction angle (2θ) tended to increase with the increase of irradiation dose.

X-射线衍射图谱分析表明，1～5kGy 剂量辐照处理可明显降低水饺皮的相对衍射强度，3kGy 辐照水饺的相对衍射强度最低；背景线强度最大值的角度位置(2θ)有随辐照量增加而增加的趋势，辐照对水饺皮淀粉老化有一定的抑制作用。

The two plans were evaluated by means of the dose coverage of the targets,dose-volume histogramand other dosimetric index.

根据靶区的等剂量分布、剂量。

MethodsThe behavior changes of learning and memory disorder induced by dysmnesia were observed on mice, related indexes were detected as well.Mice were divided into five groups randomly:normal group, control group, piracetam group, prepared Radix Rehmanniae high-dose group, PRR low-dose group.
