亡

The level of VEGF mRNA was elevated after 6h when 8Gy irradiation was processed and maintained to 72h. Sense and anti-sense expression vector were transfected into vascular endothelial cells and stable cell lines were established. Cell line transfected sense expression vector of VEGF_(165) gene showed reduced inhibition of prolifetation, MNF, MNCF and apoptosis compared to that of control vector, while opposite results were obtained in anti-sense transfected cell line.

转染正义表达载体的ECV-304稳定细胞系经过4Gy γ射线照射后，与转染空载体的细胞相比，细胞增殖抑制率减弱，MNF、MNCF以及凋亡减少；而转染反义表达载体的细胞系与转染空载体的细胞相比，细胞增殖抑制率增强，MNF、MNCF以及凋亡增加。

Methods In vitro, human gastric cancer cell line SGC-7901 in log phase was intervened by As_2O_3 (final concentrations in order:1.0,5.0,10.0μmol/L) and 5-Fu (final concentration:50mg/L) respectively alone or in combination, and incubated for 24h、 48h、 72h. Blank group is set up. The cell apoptosis and cell cycle changes were observed by flow cytometry, and the expression of apoptosis-related gene Bcl-2 was analyzed by immunocytochemical method and absolute gray scales quantitative method.

将对数生长期的人胃癌细胞株SGC-7901(终浓度为2×10~5)经低、中、高三种浓度的As_2O(终浓度分别为1.0，5.0，10.0μmol/L)和5-Fu(终浓度50mg/L)单独及联合处理，设空白对照组，分别孵育24h、48h、72h后，收取标本采用流式细胞术测定细胞凋亡率及细胞周期变化；免疫组化绝对灰度定量分析检测凋亡抑制基因Bcl-2的表达。

The phagocytosis of apoptotic cells by phagocytes is physiologic and "silent". In this way the apoptotic cells never has a chance to lyse and release pro-inflammation molecules to the extracellular space.

巨噬细胞吞噬早期凋亡细胞是生理性的和"寂静无声的"，凋亡细胞不能裂解和把能引起炎症的分子释放到细胞的空间。

The staining of brush cells of experimental group showed nuclear shrinkage, margination, nuclear fragmentation and formation of apoptotic bodies, and the characteristic ladder band on gel electrophoresis. NO changes were observed in control group.

实验组细胞刷片染色显示有明显的细胞核固缩、核周边染色质加深、核断裂、凋亡小体现象，细胞DNA电泳可见梯状条带的凋亡特征，而空白对照组无此现象。

We transformed antiapoptotic genes Bcl-2, CED-9 and PpBI-1 into the yeast to evaluate their function of resistance to cold stress. The results are as follows:(1) Cold induced apoptosis in yeast cells, moreover, yeast cells display representive features such as chromatin condensation, DNA fragmentation and chromatin margination.

而且酵母没有如Bcl-2家族的主要凋亡调控基因的同源基因，因此酵母是研究外源抗凋亡基因Bcl-2，CED-9和PpBI-1在抗冷方面的作用及其调控机制的理想体系。

The morphological changes in condensation and margination of nuclear chromatin, apoptotic bodies and cell necrosis significantly increased in gen group and gen plus ddp group.

形态学观察可见gen组和gen+ddp组细胞凋亡、凋亡小体及变性坏死增多，而对照组少见。

In light and electronic microscopy, they appeared cell shrinkage, cell density increasing and eosinophilic, aggregation of cytoplasmic organelles, nucleolus fragmentation, and chromatin margination, condensation, and fragmentation. Those changes could be detected by TUNEL method.

在光镜和电镜下癌细胞凋亡表现为细胞体积缩小，胞浆浓缩嗜酸性，胞浆出泡、细胞器缩小或减少，核仁松解，染色质聚集、靠边、浓聚、断裂，在TUNEL法检测凋亡癌细胞时也可观察到相应的形态特点。

The bulk of cells in the positive control group were dead.2 Treated with different dosages of DMF for 24h, it can be observed that green,nuclear margination and chromatin condensation were distinct in cells exposed to DMF.

研究结果 1。二甲基甲酰胺致人肝细胞凋亡形态学观察： 1不同剂量DMF染毒12h后，AO／EB染色可见阴性对照组无明显凋亡细胞，50mmol／L剂量组开始出现细胞形态接近正常，胞质为亮绿色，核出现固缩呈圆珠状，与正常细胞比较核质比变大的细胞。

The participation of mitochondria in apoptosis is one of the most important pathways.

细胞内线粒体凋亡途径是凋亡的主要途径之一。

The imbalance of apoptosis relates with the occurred mechanism of many disease. It is very important for the multicellular organism to develop and keep their stability.

凋亡的失调与许多疾病的发病机理有关，细胞凋亡对多细胞动物正常机体的发育和自身稳定起着极其重要的作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
