胞内染色质

In addition, spermiogenesis includes chromatin condensation, migration of the cytoplasm and mitochondria to the caudal pole of the nucleus, formation of a moderate axial nuclear fossa containing the proximal centriole and part of the distal centriole and presence of a short cytoplasmic canal separating mitochondria from the flagellum.

另外，精子发生过程中还包括染色质浓缩，细胞质和线粒体向细胞核的尾端迁移，在核的后端中轴位置上形成中等大小的核后凹，近端中心粒和远端中心粒的一部分嵌在核后凹之内，短的胞质内陷管将线粒体与鞭毛分隔开。

Results: electronic microscope showed that in prednisone group heterochromatin increased in some cells, entoblast was not obvious in some cells, fat drops were small and few, mitochondria vacuole were common, and myelin figure was found in smooth endoplamic reticulum. the ultrastructure in yc group was almost normal and megamitochondrion formation was common. a large amount of fat drops were found in cytoplasm in gw group and little improvement was found compared with that in prednisone group.

The changes included that the protrusions on the cell surface diminished, myofilaments and pinosomes in the myoepithelial cells of grade Ⅱ,Ⅲ atypical hyperplasia decreased, and the irregularity of the nuclear morphosis and the increase of nuclear heterochromosome were found.

乳腺不典型增生时肌上皮细胞数目增多，排列紊乱，电镜下可见：①细胞表面的棒状突起消失；②Ⅱ、Ⅲ级不典型增生时胞浆内的肌微丝和吞饮小泡减少；③细胞核增大，不规则，异染色质增多。

During the secondary wall formation of fiber, H+-ATPase, Ca2+-ATPase and APase also sustainablely remained in plasma membrane, plasma membrane invagination, plasmodesmata, transfer vesicles and agglutinated nucleus.

在次生壁形成的整个过程中，ATP酶、Ca2+-ATPase和酸性磷酸酶在运输小泡、细胞膜、质膜内陷、胞间连丝和凝聚的染色质中将持续存在。

Several masses of condensed chromatin without nuclear membrane were observed in some treated K562 cells,while chromatin of some other cells tended to marginate in crescents around the nuclear envelope with compacting cytoplasm,normal or slightly expanded endoplasmic reticulum,which presented typical morphology of apoptosis.

电镜下，加药处理组中部分细胞染色质凝集成块，没有核膜包被，部分细胞染色质靠核膜边集呈新月形，胞浆浓缩，内质网结构正常或有扩张，呈现典型的凋亡细胞形态。

Hyphae, loaded with CTC under pH 6. 8 condition and then grown in pH 8. 0 medium for a little while to destroy the apical acidification, could gave very diffuse fluorescence images of CTC membrame bound Ca〓 and vermiform fluorescence spots due to mitochondrias under pH 6. 8 no longer were clearly distinquished, which implied that besides mitochondrias, other cellular organelles with Ca〓 also were stained with CTC. Thus mitochondrias are not the only one intracellular Ca〓 storage, endoplasmic reticulums and Golgi bodies in the same zone may be also the Ca〓 storages. But the extreme apical zone under 2μm of the growing hyphal tip was still almost devoid of stain under pH 8. 0.The CTC fluorescence was concentrated in the subapic zone beyond about 2μm from the tip and then gradually became lower behind about 40μm from the tip. These results did not support the hypothesis which suggested that the cell wall vesicles in the extreme apical zone were intracellular Ca〓 storages.

将菌丝在pH6.8条件下负载CTC，再置于pH8.0培养介质中短暂生长一会儿以消散菌丝顶端的酸化区域，则CTC膜结合Ca〓呈现弥散的荧光影像，在pH 6.8培养条件下显示的蠕虫状的线粒体荧光斑点不再能够清晰辨认，说明除了线粒体之外，还有其它含Ca〓细胞器，也被CTC染色，线粒体并不是细胞内唯一Ca〓库，还可能包括内质网、高尔基体等细胞器，但菌丝最顶端2μm以前的细胞壁泡囊区域不能被染色，最大荧光强度仍位于菌丝顶端2μm以后区域，约45μm以后荧光变弱，实验结果不支持细胞壁泡囊为菌丝胞内Ca〓库的假设。

The results indicated that the erythropoietic/granulopoietic ratio was markedly increased with megaloblastic morphology in all stage of erythrocyte.

结果表明：2例CDAⅠ型患者骨髓幼红细胞比例增加，各阶段细胞存在不同程度巨幼样变；原红细胞核不规则，早幼或中幼红细胞可见奶酪核，约半数晚幼红细胞有核溶解和破碎现象，晚幼红细胞核损伤有时伴胞质溶解，细胞间染色质桥少见；各阶段红细胞核膜和内质网同时出现不同程度溶解。

A few of intercellular electron-dense zones without typical synapse were found in the inner plexiform layer.

内核层内可见胞核各异的多种细胞，部分胞核常／异染色质例接近，核仁偏心分布。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。
