In winter,nuclear of GTH cells were elliptical and a small number of secretory granules scattered around nucleolus. Number of secretory granules in STH cells were relatively small, nucleolus distorted, activity of synthesis and secretion decreased. Secretory granules in TSH cells cytoplast were relatively small.

冬季，GTH细胞核为椭圆形，有少量的分泌颗粒散布在细胞核的周围；STH细胞分泌颗粒数量较少，胞核变形，合成和分泌活动比较微弱；TSH细胞胞质中的分泌颗粒相当多。

In the normal group, electron microscopy showed normal chondrocytes were oval, and cells and cell membrane were intact. In cytoplasm, there were abundant rough endoplasmic reticulum, dictyosome, and mitochondria with intact nucleus, and even chromatin. In the model group, chondrocytes exhibited obvious pyknosis and their shape was irregular. The areolae around cells disappeared; cell organs in cytoplasm coagulated to flaps which showed electron dense and was uneasy to observe; the shape of nucleus showed irregularity, and caryotin gathered densely.

电镜下正常对照组软骨细胞呈椭圆形，细胞及胞膜完整，包质内可见丰富的粗面内质网、高尔基体、线粒体，细胞核完整，染色质分布均匀；模型对照组软骨细胞明显固缩且外形不规则，细胞周晕消失，胞浆内细胞器凝成高电子密度的片状物不易分辨，细胞核不规则，染色质浓聚，散裂于核中。

The distribution of ubiquitin positive dystrophic neurites and neuronal intranuclear inclusions were investigated. Results Morphologically,it was characterized by marked atrophy of bilateral striatum with loss of neurons and mild proliferation of astrocytes.

泛素阳性的营养不良性神经突起和神经细胞核内包涵体主要出现在大脑皮层的Ⅲ～Ⅴ层，神经细胞核内泛素阳性包涵体在大脑额叶前区皮层达22%，依次为顶叶7%、枕叶3%、颞叶1%和扣带回1%。

C cell into an egg from which the nucleus has been removed.

体细胞核转移－将体细胞中的细胞核转移到另一个已去除细胞核的卵细胞中。

German embryologist Hans Spemann envisioned an experiment—removing the nucleus from an unfertilized egg and replacing it with one from a differentiated cell—in hopes of finding a solution to the long-debated issue "nuclear equivalency".

德国胚胎学家Hans Spemann设计出一个试验，即把未受精卵的细胞核取出，取而代之以分化过的细胞核，以期解决长期争论不休的"核等效"问题。

The results of light microscopical studies showed many giant and multinucleate giant cells with even more than twenty nuclei in each cell. It was possible that the formation of multinucleate giant cells associated with repeated endomitosis in a single cell.

光学显微镜观察见K562/IL-2细胞中出现较多巨大细胞及多核巨细胞，细胞核数目可多达20余个，推测多核巨细胞的形成可能与细胞核反复分裂而胞质不能分裂有关。

It was generalized that applied foreground and current esse of problems of mammalian cell nuclear transfer technology .

简要概括哺乳动物细胞核移植技术的应用前景，详细综述其目前存在的问题，认为对待细胞核移植技术的发展，应该理性分析。

Since then, the gene localization has developed from simply being described as at the euchromatin region and heterochromatin region to more complicated nuclear localization. Therefore, the gene regulation attracted more attention now.

因此基因在细胞核内的定位就由原来简单认为的异染色质区和常染色质区发展得更为深入了，基因在细胞核内的定位以及位置的变化与基因表达调控之间的关系也越来越受到重视。

The neuron apoptotic cells were observed by their fragmented nuclei condensed chromatin, fragmented or condensed cytoplasm and floccule of mitochondrion in the control group after ischemia 90 min/ reperfusion 12 h; whereas the distribution of chromatin was well-proportioned, and normal mitochondrion and other organelle were observed in the Ginkgo Biloba Extract-treated group.

对照组缺血90 min再灌注12 h鼠脑组织电镜检查可见神经元细胞核染色质边聚，呈团块状，线粒体可见絮状结构改变；相同时限药物治疗组脑组织神经元细胞核染色质分布比较均匀，胞质内线粒体及其它细胞器基本正常。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
