细胞核

Histones are protein- found in eukaryotic cell nuclei, tightly bound to DNA, which has many phosphate groups.

组蛋白是存在于真核细胞核中的与含很多磷酸基团的DNA紧密结合的蛋白质。

Covalent modification of histones on chromatin is a dynamic mechanism by which various nuclear processes are regulated.

染色质上组蛋白的共价修饰是一个动态的机制，多种细胞核过程通过该机制被调控。

It was found that pathological changes could be demonstrated in villi of small intestine, lamina propria of stomach and myocardial cells in case of mice orally administrated with RV, while in case of mice intra-abdominally injected with RV, pathological changes could be demonstrated also in liver and kidneys in addition to the changes mentioned above.

结果 光镜下：RV口服组小肠绒毛、胃固有层、心肌细胞有改变；RV腹腔注射组除上述改变外，肝，肾也有改变；电镜下：肝细胞线粒体肿胀、凝集病变尤为明显，细胞核固缩－崩解，粗面内质网扩张，肝细胞中存在大量脂滴和空泡；毛细胆管明显扩张，微绒毛脱落。

Result: 1 HE staining 2 immunohistochemical method:①the positive expressive rate of Bax in proliferative phase and involuting phase of hemangioma, normal skin tissues in turn were

结果 1 HE染色：增生期血管瘤组织中可见条索状或片状内皮细胞增生，其间有不规则的内皮间隙和完整的血管腔，内皮细胞核肥大而淡染。

Objective To investigate the expression of vascular endothelial growth factor and proliferating cell nuclear antigen in keloids and hypertrophic scars.

目的 探讨瘢痕疙瘩和增殖性瘢痕等异常疤痕中血管内皮生长因子和增殖细胞核抗原的表达及其意义。

Results: When incubated with different concentrations mitomycin for 24 hours, the body cells from 40μmol/L to 70μmol/L showed apoptosis under transmission electron microscope, chromatin condensation, even nuclear fragmentation, to form the apoptosis body can be seen.

体细胞经不同浓度的药物处理24h后，透射电镜下发现在40μmol/L～70μmol/L的各组细胞均有凋亡细胞，细胞核固缩、凝聚，甚至断裂，形成凋亡小体。

1 The changes of form and tiny formation: the volum of lymphoblasts largened and the nuclei were transparent and ball agglutiphenomenon occurrded.

6培养细胞的常规观察： 6.1形态和细微结构变化：淋巴母细胞体积变大，细胞核明显，有团块凝集现象。

The medullae showed acidophilia staining. Necrotic tumor cells were in some areas. Nuclei and cell membrane disappeared.

有的区域可见凝固坏死的肿瘤细胞，细胞核和细胞膜消失，只可见肿瘤细胞和团块的轮廓残留。

The tetrad of megaspores was linear shaped, with one of them being functional.

锥栗胚胎为蓼型，功能大孢子发育成熟时共具有七个细胞八个细胞核，通过双受精作用，产生胚和胚乳，胚胎发育经历球形胚、心形胚、鱼雷形胚到子叶胚的过程。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
