常染色质

AB型和B1型异型性不明显，细胞核常染色质较均匀，可见小核仁；

Type AB and B1 thymoma have nuclei with evenly distributed euchromatin and small nucleolus .

B2、B3型胸腺瘤异型性较明显，常染色质较丰富，核仁明显，细胞质宽大，有突起。

Type B2 , B3 thymoma have obvious atypia with rich in euchromatin and distinct nucleolus in nuclei and broad cytoplasm with projections .

H4的乙酰化可促进常染色质的形成和转录的进行，而H3K9二甲基化作用则相反。

H4 acetylation is related with euchromatin formation and switches on transcription , while H3 dimethylation acts in the opposite way .

细胞核染色苍白呈空泡状，应为主要含有的是不着色的常染色质。

Their nuclei are pale and vesicular , containing mainly unstained euchromatin .

那些表现正常的浓缩格式的部分叫做常染色质。

That which shows the " normal " condensation pattern is called euchromatin .

晚幼红细胞和成熟红细胞的核内常染色质区域有较多的血红蛋白，核膜孔较少，核周隙明显增宽。

The acidophil erythroblast and erythrocyte had more hemoglobin in the euchromatin areas of nuclei , less nuclear pores , and wider perinuclear space than polychromatophil erythroblast .

线粒体排列整齐，大小形态正常，包膜完整，嵴密集、规则；心肌细胞核呈梭形，常染色质丰富，分布均匀，异染色质少.核仁明显。

Neatly arranged mitochondria , the size of the normal form , capsule integrity , ridge-intensive rules ; myocardial nuclei were spindle-shaped , rich in euchromatin , distribution , less heterochromatin .

细胞核膜凹陷、固缩，核异、常染色质分布异常，胞浆膜破裂，线粒体空泡变，弹力纤维疏松，基底膜变形。

Subsidence of nuclear membrane , coagulation of nucleus , abnormal distribution of euchromatin and heterochromatin , split of plasmalemma , vascular degeneration of mitochondria , slackness of elastic fiber and metamorphosis of basement membrane were observed .
