核仁

Psammoma bodies are less frequently found at cytological examination from ne-needle aspiration. Their nding in cytological preparations, however, strongly suggests malignancy, in particular, papillary thyroid carcinoma, although they are an unreliable predictor of this tumor in the absence of the other typical cytological features, such as nuclear grooves,micronucleoli, and true papillae .

沙砾体是不经常从细胞学检查细针穿刺发现，虽然肿瘤在没有其他典型的细胞学特征，如核沟槽，微核仁，和真正的乳头时，他们是不可靠的预测，但是细胞学的发现强烈暗示恶性肿瘤，特别是乳头状甲状腺癌。

Transmission electron microscope results revealed vascular endothelial cells with normal morphology in the control group and tumor cells with apparent nucleoli in the Ad-GFP group, while in the Ad-aMMP-2 group, some vascular endothelial cells exhibited chromatin pycnosis in the nucleus, forming apoptotic bodies.

Observed with transmission electronic microscope,ES-like cell have obvious nucleolus and a little heterochromatin,and many ribosomes in the cytoplasm with much endoplasmic reticulum and mitochondria. A part of cells appeared alveoli on the nuclear envelope,and chromatin was pycnosis and the .

在透射电镜下细胞核仁明显、核异染色质少；细胞质中核糖体较多，内质网、线粒体发达，部分细胞的细胞核膜上出现小泡，染色质边集，染色质形成凋亡小体。

These are small, brown shrimps cooked gently in clarified butter spiked with, those most English of spices, mace and nutmeg and then allowed to set in a ramekin.

在平底锅里把黄油融化掉，大多数英国人会选择往里面加肉蔻的皮和种子的核仁，接下来把褐色的小虾仁浸泡在清亮的黄油里，冷藏起来，待黄油完全凝固，一道黄油虾仁就大功告成了。

The HUVECs retained spindled shaped or cobblestone appearance and positively stained by anti-CD31. DAPI staining showed that 90％of scaffolds surface was reendothelialized and endothelial cells were distributed evently on the surface forming a confluent monolayer.

脱细胞支架细胞成分完全脱去，胞外基质保存完好；分离的细胞培养一周后，细胞呈梭形或多角形，核仁清晰，大小均匀，呈典型的铺路石样；免疫荧光检测可见细胞胞浆内有颗粒状红色阳性信号，说明Ⅷ因子相关抗原染色阳性；膜表面有蓝色阳性信号，说明CD31抗原染色阳性。

It is suggested that the algae symbiot can affect host organellar function,quantity and location, stimulate the food uptake and digestive activity, restrain the functional activity of the organelle, change the gene expression and cause the change of genome structiure in the P. bursaria-chlorellae system.

据结果推测，纤毛虫中的藻类共生体可影响宿主细胞中胞器的功能、数量和分布，可影响细胞核核仁的数量和分布；可影响宿主细胞的形态、生长、抗氧化能力及胞质糖含量；可影响宿主细胞的食物摄取及相关胞器的消化活性，抑制宿主胞器的功能活动；并可改变宿主细胞基因的表达，导致细胞基因组结构的变化。

Immunofluorescence staining and reverse transcription polymerase chain reaction were used to test the expression of syndecan-1 protein and its mRNA in cultured unstimulated RPE cells.

2在正常RPE细胞，可检测到syndecan一1蛋白和mRNA的表达；第四军医大学硕士学位论文未受刺激的RPE细胞胞膜/胞浆、核仁呈现强的黄绿色荧光；随TNF一。

The tumor cells are large in size, very pleomorphic, and have abundant, vacuolated to dense cytoplasm, and hyperpchromatic nuclei with irregular contours and prominent nucleoli.

瘤细胞个大，多形性明显，浆丰，胞浆从空泡状到致密，核深染，外形不规则，核仁明显。

RESULTS:①Morphology of skeletal myoblasts: After 48-72 hours primary culture, the cells were completely attached and gradually extended in the shape of spindle with the round nucleus, paralleled along their longitudinal axis and appeared chromatospherite. After 5-day culture, the cells stretched out one or several apophyses.

结果：①骨骼肌卫星细胞的形态：原代培养48~72 h细胞完全贴壁，呈梭形或纺垂形，长轴平行排列，胞核圆形，核仁明显。5 d时细胞可伸出一个或数个突起。

The cells survival rates of every group were determined by MTT technique.Results The tumor cells without any anti-glioma factor treatment were growing better and no change was observed in morphology.After 2-3 days,cell axons disappeared,cell bodies crimpled,nucleoli crinkled and cracked in each treated group.

结果 未加任何抗癌因子处理的C6细胞组肿瘤细胞生长旺盛，细胞形态无明显改变；各处理组的肿瘤细胞2～3天后开始逐渐出现细胞突触消失，细胞变圆，胞体皱缩，核仁固缩、裂解、甚至消失，继而逐渐死亡。

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。
