核仁

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。

So,we can say that B23 may bind to RPS10 methylated and store it in the GC region in nucleus.

这项研究说明，B23能够选择性的结合甲基化的RPS10，并将其存储在核仁颗粒区。

By in situ hybridization, 53BP2 mRNA expression is revealed in tumor cell nests of NPC paraffin sections. The strong positive particles localize in the nuclei of tumor cells; but slight positive signals are also found in tissue cells of chronic nasopharyngitis and connective tissue, such as lymphocytes and smooth muscle cells; There are also positive signals in the nuclei of hyperplastic squamous epithelial cells. However, 53BP1 mRNA expression is not found in nuclei of tumor cells, tissues of chronic nasopharyngitis and connective tissue.

原位杂交结果显示，石蜡切片的鼻咽癌癌巢内，可见53BP2的强阳性表达信号，信号呈紫色颗粒状分布于胞核，核仁清晰可见；而在相同条件下，在慢性鼻咽炎组织和癌旁上皮的结缔组织，也可见弱表达信号，如淋巴细胞和平滑肌细胞；在增生的鳞状上皮细胞的核内，可找到强阳性信号。53BP1在鼻咽癌、慢性鼻咽炎组织和癌旁上皮的结缔组织切片上，均无表达信号。

In the treatment of higher concentration of NaN_3,some cells appeared crystalloid,two nuclei,abnormal nucleus,nucleolus losing.

较高浓度NaN3处理的PLB细胞中出现晶体物质、双核、畸形核和核仁丢失等现象。

Treated by higher concentration of EMS,some cells appeared micronuclei,abnormal nucleus,poly nuclei,broken nucleus,and nucleolus losing.

较高浓度EMS处理的PLB细胞中出现微核、畸形核、多核、核破裂和核仁丢失等现象。

The significant changes were obseved in the morphology,size,number and the degree of development of nuclei,nucleole,mitochondrial and chloroplast of apicalmeristem cell.

在这期间茎端细胞内核仁、线粒体、叶绿体等的形态、大小、数量、发育程度等发生明显变化。

There were two or more nucleole in the nuclei of the apicalmeristem cell when the plant went into reproductive phase from vegetative phase.

植株由营养生长转入生殖生长时，茎端细胞的核内有2个或多个核仁。

Results:Typical apoptotic cellular changes were found after As2O3 treatment,transmission electron microscopy showed nucleole disappeared,chromatin condensated under nucleonic membrane.

结果：经As2O3作用后VSMCs出现典型的凋亡变化，透射电镜下可见细胞核仁消失，染色质浓缩聚集于核膜下。

Thirdly,The nuclear chromatin of lung carcinoma cells concentrate to periphery, the electron density of cytoplasm increased, in some cells,the heterochromatin of nucleus were blurry,and the nucleole became uniform in electron density, the formatio reticularis of nucleole disappeared.

细胞核的改变：细胞核内染色质边集，基质电子密度增高。有些细胞核内异染色质分界不清，核仁呈均一电子密度，网状结构消失。

The ultrastructure:monstrous nucleus,ovious nucleole,desmosome-likestructure and surface microvilli.

电镜观察细胞核形状怪异，常染色质为主，核仁明显，细胞器少，可见高尔基器，有桥粒样结构，表面有许多绒毛状突起。

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。
