染色质的

The neoplastic epithelia are low cuboidal and not columnar in shape, with very large and atypical oval nuclei with vesicular chromatin and prominent nucleoli.

肿瘤性上皮呈低立方状而不是柱状，有很大的卵圆形核和显著核异型性，空泡状染色质和显著核仁。

The demethylation of DNA and acetylation of core histone reconstitute chromosome struction which is beneficial to gene transcription.

DNA去甲基化与组蛋白乙酰化导致染色质构象发生有利于基因转录的变化，基因具有转录活性。

"Think about a chromosome as being a highway," says Aramayo. In order to function properly, some sections of the highway must have illumination, which means DNA must be expressed, whereas other sections must not have illumination, which means DNA must not be expressed, or that the region must be heterochromatic.

Aramayo说，我们可以将染色体想象成一条高速路，为了正常运行，高速路的一些区段需要照明，也就是说DNA必须被表达；而其它区段则不需要照明，即DNA不需要表达，或这些区段必须被异染色质化。。。。。。。

It was demonstrated that in the results of both Se-intake and non-Se-intake trained rat muscles, the appearance of unclear cells karyons condensed chromatins karyon's being packed against nuclear membrane and thickening of nuclear membrane changed.

结果发现，无论补硒还是不补硒运动组均有细胞核染色质浓缩及靠近核膜、核膜增厚等典型细胞凋亡的形态结构改变，运动训练可能导致骨骼肌细胞出现凋亡。

Ultraviolet radiation can induce HaCaT cells apoptosis.One of morphological feature of cells apoptosis is karyopyknosis and clumped chromatin and formming circularity or crescent.

紫外线辐射HaCaT细胞可诱导凋亡，细胞发生凋亡的形态学特点之一是细胞核固缩，染色质浓缩，凝集，形成环状或新月体结构。

Results When the cells were treated with Sodium Selenite at a concentration of 2.0mmol//L lasting 72h, karyopyknosis and chromatin condensation were observed under microscope; When the cells were treated with Sodium Selenite at a concentration of 4.0mmol/L lasting 72h, the cells in G0/G1 and S phase was significantly decreased, a typical apoptosis peak before G1 phase was shown.

结果 2.0mmol/L亚硒酸钠作用72h， HE切片可见核固缩、染色质边集等改变；4mmol/L亚硒酸钠作用72h， G0/G1期和S期细胞明显减少，在细胞周期G1前期可见典型的细胞凋亡峰。

The proliferation of SGC-7901 cell line was markedly inhibited by shRNA-GC-CⅢ（ P .05）. There was changes in cell morphology, such as cell volume reduction, karyopyknosis and chromatin conglomeration. FCM showed that GC-C inhibition caused the appearance of sub-G 0 /G 1 peak which increased from 5.47%（48h after transfection） to 5.63%（72h after transfection）.

转染GC-C shRNA真核表达载体后SGC-7901细胞的增殖能力受到抑制（ P 。05）；细胞形态发生改变，细胞体积缩小，核固缩，染色质浓缩聚集于核膜；流式细胞术检测显示G 1 峰前出现亚二倍体峰，转染48、72h后凋亡率分别为5.47%和5.63%（ P nbsp； 0.05）。

Fig.10 Showing K562 cell line treated with CA for 24h:an apoptotic cell with condensed chromatin marginated in crescents around the nuclear envelope.

图10 示2μm/L CA作用24h，加药组中1个凋亡的K562细胞，可见其染色质靠核膜边集，呈新月形

Fig.13 showing K562 cell line treated with NCTD for 24h:an apoptotic cell with condensed chromatin marginated in crescents around the nuclear envelope.

图13 示10mg/L NCTD作用24h，加药组中1个凋亡的K562细胞，可见其染色质靠核膜边集，呈新月形，胞浆浓缩

Using electronic microscope we not only observed the change of apoptotic cell chromatin such as chromatin condensing and margining but also watched the change of mitochondrias.

本实验通过电镜观察到凋亡细胞染色质聚集、趋边等表现，同时也观察到线粒体的改变。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
