Therefore , it is important to study the profiles of gene expression , which will help understand the global cellular stress responses to chemical carcinogens , and further elucidate the mechanisms of nontargeted mutagenesis 所以，从整体上研究烷化剂作用后细胞基因表达谱改变，对于了解化学致癌物诱发的哺乳动物细胞应激反应的全貌和揭示非定标性突变的发生机制具有非常重要的意义。
These results , combined with earlier work , suggest that a distress response to a noxious stimuli may be almost entirely subcortical , however , the finer discrimination and emotional overlay of this painful appreciation may be cortical in location ( 1 ) 这些结果与早期研究综合表明，对伤害性刺激的不良应激反应可能完全是皮层下的，然而，对疼痛鉴别的良好判断和情感性加重在局部可能为皮层水平。
Results showed , after the lymphocytes accept the radiation , the luminescence was enhanced by mcla - a kind of luminescence probe . enhanced luminescence increased with the radiation dose firstly , then descended . this phenomenon is the result of stress reaction of radiated lymphocyte 实验显示，淋巴细胞受辐射后，在化学发光探针mcla的作用下，化学发光会增强；被增强的化学发光随淋巴细胞受辐射的剂量的增大先增强后急剧降低，而这种关系正是淋巴细胞活性与淋巴细胞受辐射后的应激反应的结果。
Objective to study the effects of operation by different anesthetic techniques on canine neuroendocrine and immune responses to stress , discuss mechanisms of immune depression at postoperation and provide therotical bases for alleviating stress reaction and immune depression during and after operation 目的探讨4种不同麻醉方法下手术对犬应激性神经内分泌及免疫反应的影响，寻求术后动物免疫抑制发生发展的规律，为减轻术中应激反应及术后免疫抑制提供理论依据。
In order to get some functional clues from their structures , the upstream regulation region of ndrgl gene and second structure of ndrg2 protein are performed bioinformatics analysis ; we found that there are several binding sequences of some diffirent transcription factors , their functions include regulating tissue - specific gene expression , regulating expression of genes related to growth and early development of cells , besides this , regulating expression of genes under some stimulated conditions , and so on . predict in protein fold classification shows that ndrg2 belongs to alpha / beta hydrolase fold family , and there are high similarity between ndrg2 and epoxide hydrolase from bacteria , this suggests that ndrg2 protein may has enzymatic functions associated with resisting the oxidative stress , maintaining the balance of cell redox potential , involving in the metabolism process of xenobiotics or intracellular toxic molecules 研究发现呷基因的调控区存在多种转录因子结合位点，功能主要涉及组织特异性表达调控，细胞生长发育相关基因的表达调控，刺激反应基因的表达调控等； ndrgz蛋白在结构上属于a小水解酶类折叠，折叠分类预测表明ndrg2与其中的的细菌环氧化物水解酶的二级结构极为相似，提示ndrgz蛋白具有一定酶活性，可能参与细胞抗氧化应激反应，维持细， an ） armtbffiofbfochmilsyn ） mdafblechmrbfobo4第四军医大学硕士学位论文胞内氧还电势平衡，参与内外源有毒物质的代谢等。
The headteacher can stay with the students and observe them all day ; he cam influence the students through his adminisiration ; be can create a small society with good atmosphere in the class ; be can communicate easily with the parents of the students and the society ; he can prevent the students ' improper reaction according to the regularity of the activities in the school and he can intervene urgently in the students ' improper behaviour 班主任可以与学生一起生活，朝夕相处，观察方便；班主任有管理学生的权力，可以通过管理影响学生；班主任可以将班级创造为一个心理氛围良好的小社会；班主任可以与学生家长、社会沟通；班主任可以根据学校活动的规律，预防学生的心理应激反应失当；班主任可以对学生的不良行为进行紧急干预。
The research purpose is to understand its sulfide tolerating mechanism from physiological , biochemical and molecular biological areas . a series of experiments show that u . unicinctus can respond to the sulfide of its living environment . when it is exposed to sulfide , its oxygen consumption changes ( 0 . 05 ~ 0 . 07mgo2h - 1g - 1 ) corresponding to various sulfide concentrations 经过一系列的实验，我们认为单环刺?能对生活环境中的硫化物做出相应的应激反应；其单位耗氧量随硫化物浓度的不同而在0 . 05 0 . 07mgo _ 2h ~ ( - 1 ) g ~ ( - 1 ) (湿重)间变化。
Gene population encoding proteins that involve in plant defensive reactions and adversity resistance , such as p1a5 gene encoding a non - specific lipid - transfer protein , p1b4 gene encoding a raucaffricine - o - p - d - glucosidase and p2d4 , encoding a proline - rich protein ; ( 2 ) gene populations with antagonistic effects occurred simultaneously in sprouting bract , e . g . , 如pib4基因编码的葡萄糖昔酶、 pias基因编码的植物脂肪转移蛋白、 pzd4基因编码的一种富含脯氨酸的蛋白都有参与植物的抗逆、防御或应激反应的功能八2 ）幼嫩苞片中有互为桔抗作用的基因同期表达。
