When the inorganic crystal in clay is irradiated by the above radioactive materials , part of the radiation will be released in the form of light and the rest will be trapped in the crystal 同时，粘土中又含有各种无机晶体和矿物质。当无机晶体受到上述放射性物质照射后，一部份辐射能量会令晶体发热，另一部分能量则贮藏在晶体中。
Some other few patients may suffer from slight maladjustment of movement , local numbness or other neural disorders within a few of weeks or months after the treatment , but they can also be recuperated by themselves or under the help of medicines 还有少数病人在照射后几周或数月，可能出现轻度运动失调局部麻木等神经系统体征，一般也可自行修复或经药物治疗恢复正常。
5 . after induced with iptg , jm109 with pgex - 4t - l / 6 - 4 was radiated by uv for 30 seconds , cultivate these e . coli with light or without light . the survival rate proved the gene of d . salina ( 6 - 4 ) photolyase has photoreactivation 5 .工ptg诱导过的转化菌，经过30秒的紫外光照射后，分别进行光培养或暗培养，计算存活率，从而证明了及sa了z ’ na的( 6一4 )光裂合酶在大肠杆菌中可进行光修复活性作用。
Different from traditional surgical operation that can remove the morbid tissue at a time , gamma knife treatment requires a long - term period for gradual metamorphosis and putrescence after the garget tissue has been irradiated . generally the period can be divided into the following three stages 它不像外科手术那样可以马上切除病变组织，需要治疗的部位在接受一次性照射后，有一个蜕变坏死的较长过程，一般可分为三个阶段：
Second , balb / c mice were conditioned with 9 . 0gy lethal tbi and divided into two groups randomly . group a were injected with bone marrow cells 4x107 and speen cells 2107 from chimeric rats , and group b injected with bone marrow cells 4xl07 and speen cells 2xl07 from normal rats 第二步， balb c小鼠经至死剂量全身照射后随机分为两组， a组输入嵌合体大鼠的骨髓细胞和脾细胞， b组输入正常大鼠的骨髓细胞和脾细胞，比较gvhd发生情况。
The protein level of p27 klpl increased at ih , decreased from 6 to 24h after 2gy , it decreased from 3 to 24 h after logy , and the level of p27kipl associated with cdk2 decreased , then lost its inhibition function to cyclin - dependent kinase Eycline / enkz的负调控因子p27k ， p ’蛋白表达水平在zoy照射后lh略有增加， 6一9h开始下降; 10gy照射后3h开始下降，持续到24h ，可见，随着ir剂量的加大和处理时间的延长， p27kip ‘蛋白表达水平下降的程度加大。
The section plane display algorithm is studied in the thesis , and the interaction section and curve section display is achieved , which can provide the aids for observation and analysis of organs . also , it is very helpful for the dose distribution analysis 本文研究了显示任意剖面的算法原理，并实现了交互式的任意剖面显示和曲线剖面显示，这不仅能为器官的观察、分析提供帮助，同时能为在组织器官受到射线照射后定量、定位地分析剂量分布提供很好的手段。
The expression of topoisomerase ii of cultured cells treated low dose ionizing radiation decreased and then returned as time went . and become outstanding as radiation dose and frequency were added . inhibitor of topoisomerase ii could cause chromosome non - dis juction in mitosis and meiosis . and the co - effect of inhibitor of topoisomerase ii and ion 05 ） ，具有随照射次数增加而增加的趋势；小剂量电离辐射可以引起拓扑异构酶a表达变化，随照射后时间延长先下降后回升，随照射剂量和次数的增加，变化更加明显；拓扑异构酶11a抑制剂可引起有丝分裂和减数分裂时染色体的不分离；拓扑异构酶a抑制剂和电高辐射的协同作用使染色体不分离更加明显。
The protein level of cyclin e increased lightly after 2gy , but it increased from 1 to 24 h after logy , level of cyclin e associated with cdk2 increased in response to logy , at the same time , there was no significant changes in the level of cdk2 , while cdk2 levels remained constant in hela cells . our results indicated that the kinetics of cyclin e / cdk2 kinase activity reflected the increase in cyclin e expression levels Cycline蛋白表达水平在zgy照射后略有增加， 1ogy照射后lh开始增加，持续到24h ，但ir后cdkz蛋白水平未发生变化，通过免疫共沉淀检测了10gy照射后edkz与cydine结合，发现随着照射时间的延长， cycline与cdkz结合量增多，这说明cycline蛋白水平的增加能反映cycline / cdkz的激酶活性。
Different from traditional surgical operation that can remove the morbid tissue at a time , full - body gamma knife treatment is a kind of non - invasive radiosurgery that requires a long - term period for gradual metamorphosis and putrescence . to analyze its curative effects , you can refer to the following internationally universal standards : 1 体部伽玛刀的治疗不同于外科手术，可立即摘除病变组织，它采用的是无创放射治疗，病变组织在被照射后，有一个蜕变坏死的变化过程，在分析其治疗效果时可采用目前国际上通用疗效判断标准：
