核仁的

OVCs were isolated by density ladder centrifugation in the 4th week, and then OVC's morphology was observed under transmission electromicroscrope and immunocytochemistry were performed to detect the expression of ICAM-1. Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast.

结果 透射电镜下观察到OVCs超微结构的改变为核大，核/浆比大，核仁小，胞浆内细胞器少，可见少量内质网和小线粒体，整个细胞呈幼稚、未分化状态；ICAM-1免疫细胞化学检测阳性；损伤肝组织HE染色和ICAM-1免疫组化检测显示，肝损伤初期，Hering管周围OVCs增生并且ICAM-1阳性表达，随着肝损伤的加重，OVCs继续增生，并且，OVCs沿增生的肝纤维向肝小叶迁移，同时，ICAM-1阳性表达也继续增多，并逐渐向肝小叶弥散分布；透射电镜下观察到，肝损伤初期，OVCs在Hering管周围增生，肝纤维随之增生，增生的OVCs与肝纤维黏附生长。

Results Observing OVC's morphology under transmission electromicroscrope showed that OVC was infantile and undifferentiated with big nucleus, clear nucleolus, large nucleoplasm-ratio, small mitochondria, and little endoplast. In initial stage of damaged liver, OVCs and the expression of ICAM-1 mostly distributed around Hering duct, and then gradually increased and expanded toward hepatic lobule, shown by staining paraffin sections with HE, immunochemistry and transmission electromicroscrope. Immunocytochemistry indicated that ICAM-1 expression on OVCs was positive.

In resting cysts, the microtubules under the pellicle, cortical ciliatures, conjunctions between cilia basal bodies, supporting structure of basal bodies and other microtubule structures are absorbed in different extent; microtubule-like assemble bodies appear at the center of the remained cilia basal bodies; the granules of chromatin and nucleolus in macronucleus become smaller whereas nucleus pores of the micronucleus become bigger; the inner membrane of some nucleus pores are attached with chromatin.

结果表明：纤毛虫形成包囊过程中，皮层细胞质中产生具有自噬泡消化特征的细胞器，将部分纤毛结构等逐步消化；休眠包囊中，表膜下微管、皮层纤毛器和纤毛基体间连接、基体托架及其他微管结构不同程度地被吸收、在残剩纤毛基体的中央形成微管形结构聚合体，大核染色质和核仁颗粒变小，核孔增大，并发生染色质附着于核孔内膜的现象；细胞脱包囊期间，皮层细胞骨架、线粒体等经历了在残剩结构基础上的再分化。

The results show that, with the maturity of the gonad, the undifferentiated germ cell divided and differentiated to smaller oogonium or spermatogonia, and the oogonium or spermatogonia transformed to oocyte and sperm undergoing a series of maturation process.

摘 要 通过观察栉江珧的未分化生殖细胞，精原细胞和卵原细胞，精母细胞和卵母细胞，精子和卵子的形态结构与分布状况及核仁在卵成熟过程中的变化，对栉江珧生殖细胞发生及成熟过程的有关问题进行了探讨。

The localization of 〓 changed during the process of rat oocytes maturation. In GV stage oocytes,〓 was concentrated in GV but it concentrated around chromosomes from metaphase Ⅰ to telophase Ⅰ.

〓的在大鼠卵母细胞内的定位随成熟分裂的过程而变化：在GV期生发泡内核仁周围有特异分布，在成熟分裂的中期至末期〓在染色体周围区域有特异分布。

On the 14th day after yolk sac had disappeared, gonad had differentiated to ovary.

生殖腺中卵的成熟及卵巢腔的形成是「由前往后之层次」成熟，在卵黄囊消失后第四十九天的鱼苗，卵巢的发育至周边核仁期。

Cytology reveals cells with clear to lightly basophilic cytoplasm and round or indented nuclei with fine chromatin and indistinct nucleoli.

细胞学分析可见透明至浅染的酸性细胞质和圆形或缩进的细胞核含有正常的染色质和模糊的核仁。

The new GV preparation method we developed allowed the best visualization of chromatin distribution after Hoechst or CMA3 staining. Our results showed that GV chromatin configurations are different among different species, and thus, while chromatin condensed into a ring around the nucleolus in porcine and bovine oocytes, no such a ring was observed in caprine oocytes; Porcine oocytes were synchronized at GV1, goat oocytes at GV3n and bovine oocytes at GVf configurations before GVBD occurred, indicating that these configurations are progressive towards final maturation rather than atresia; Changes of chromatin configurations were associated with gene activity of transcription; GV chromatin configurations were affected by the environmental changes such as serum starvation and elevated temperature.

应用该技术对猪、山羊和牛不同大小、不同健康程度卵泡及体内和体外成熟过程中卵母细胞染色质构型的变化发现：1）不同动物卵母细胞染色质构型不同；猪和牛卵母细胞染色质围绕核仁凝集形成环，但山羊卵则没有此环。2）卵母细胞在GVBD之前都同步在某一染色质构型；猪同步在GV1，山羊GV3n，牛GVf，说明这些染色质构型代表着进行性变化。3）染色质构型的变化反映基因转录活动的变化。4）染色质构型受环境变化的影响。

The most common architectural pattern was cribriform (73%), followed by fused/poorly defined glands (55%), cords/single cells (11%), and solid sheets (5%). Nuclear enlargement was observed in 45 of the 55 studied cases (82%). Prominent nucleoli were either absent or infrequent in 38 cases (69%).

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。
