- Radiation Accumulated Dose 辐射积聚剂量
- Methods Blood samples were collected from patients exposed to radiation at the accumulated dose of 0, 4, 10, 28, 48 Gy and 68 Gy for the comet assay and determination of DNA damage and hprt gene mutation, respectively. 方法 在病人接受放射治疗累积剂量为 0、4、10、2 8、48Gy和 68Gy时 ,取病人外周血淋巴细胞分别进行彗星试验 ,淋巴细胞DNA的损伤及hprt基因突变检测。
- The mean annual dose and the mean accumulated dose for the whole bodywere 0.26 rad and 3.24 rad,respectively. 平均年剂量为0.;26rad;平均累积剂量为3
- However, under more accumulated dose, there is no error in devices in power off mode and new data can be written in these devices with programmer. 然而不加电的器件在更高的累积剂量辐照下未出现错误,而且可以用编程器重新写入数据。
- There is an accumulated dose threshold.Errors occur when accumulated dose is above the threshold, no error occurs when below the threshold. 器件出现错误有个累积剂量阈值,当累积剂量小于某一值时,无数据错误。
- After 10~20 min,if the resuscitation was not good,the above intravenous injections can be given again,the maximum accumulated dose was 450mg(AM) and 210mg(propafenon). 观察10~20分钟若未转复可重复应用,最大累积量胺碘酮为450 mg,心律平为210 mg。
- The relations were analyzed among clinical symptom, accumulated dose, endoscopic findings of esophagus, pathological changes and the rate of chromosome aberrations and micronuclei with lymphoid blood. 方法 对我科收治的放疗照射野包括食管,符合入组条件的病人,采用多种国际上常用的评价方式(RTOG临床评分、内镜评分、食管炎指数)评价急性放射性食管炎,并在不同的累积剂量点观察外周血淋巴细胞染色体畸变率、微核率,分析RTOG临床评分、累积剂量、内镜下发现、病理改变、外周血淋巴细胞染色体畸变率、微核率之间的关系,观察各项指标的诊断价值。
- maximum permissible accumulated dose 最大容许累积剂量
- MLD RIT could increase the accumulated radiation dose. 多次RIT能有效的提高肿瘤组织的累积辐射剂量。
- Results The HPRT gene mutation frequecy rose with the increase of accumulative dose and the doserate,both relationships could be described by linearquadratic models. 结果随着累积剂量和剂量率的增加,HPRT基因突变频率随之上升,其剂量效应关系符合线性平方模型。
- In the accident, the workers received a heavy dose of radiation. 在这次事故中,工人受到大剂量的辐射。
- Lead aprons shield people from radiation. 铅做的工作裙可使人免进辐射。
- Results The clony efficiencies of rat peripheral blood lymphocytes and spleen lymphocytes both declined with the increase of accumulative dose,while the HPRT gene mutation frequency rose. 结果外周血淋巴细胞和脾淋巴细胞的克隆效率均随内照射剂量的增加而降低,HPRT基因突变频率均随放射性核素内照射剂量的增加而增加。相同条件下,脾淋巴细胞HPRT基因突变比外周血淋巴细胞敏感。
