查询词典 nucleus

In mouse, the position of first polar body (PB1) and MⅡ nucleus or spindle is moveable and thus it is difficult to enucleate beneath the PB1. In this study, the 3% sucrose treatment was prepared for enucleation.

The series of changes in quantiative and spatial distribution of the three cytoskeleton elements throughout the maturation course of FVA cells was coincided with the process of nucleus eccentricity in position and denucleation, and all of the changes began at the early stage of erythroblast.

一。采用细胞免疫荧光组化方法系统地观察了微丝、微管和中间纤维骨架成分在红系细胞终末分化各阶段的动态变化。

The amount of vimentin IF per cell was higher than those of tubulin and F-actin at 12-24h of culture, but it broken down and decreased steadily when the cells became differentiated into late erythroblast at 36-48h of culture, thus facilitated the eccentric nucleation which we regard it as the initial step of denucleation. Both of the fluorescence intensity of tubulin and actin exhibited a significant rise and aggregated between the extruding nucleus and incipient reticulocyte before and during denucleation, and finally play a role in the commitent to ennucleation, the second phase of denucleation.

在培养24小时前，每个细胞中波形纤维含量均高于同期微丝和微管蛋白含量，但在培养24-36小时的晚幼红细胞阶段，波形纤维蛋白降减和解聚，为核偏位创造了条件，这是排核的第一阶段，而随后微丝和微管蛋白的荧光染色强度则有所增加，并逐渐聚集在外排中的核与预期形成网织红细胞之间的缢痕区，在将细胞核排出的排核第二阶段起主要作用。

These changes occur in many tissues but are best known in the precursors of red cells in the bone marrow which is said to exhibit megaloblastic erythroblastosis. In addition to nuclear enlargement in megaloblasts there is increased amount of cytoplasm, cytoplasmic basophilia due to excessive RNA and premature haemoglobinisation as judged by the immature state of the nucleus.

这些变化出现于许多组织，但在巨成红细胞生成的骨髓红细胞前身中最好识别，巨成红细胞除核增大外，胞浆量增加，由于RNA过多致胞浆呈嗜碱性和早熟的血红蛋白形成，这是根据其核的不成熟状态而作出的判断。

Results showed that the monochromatic lights were advantageous to the Pchlide reduction and biosynthesis for etiolation seedling of Phaseolus radiatus in illumination for 0.5 h at first. The monochromatic light did not favor for Chlide esterification after illumination for 2 h. Chlide esterification was controlled by the cell nucleus gene, because Chlide esterification rate was restrained to the seedling leaf of P. radiatus.

结果表明：绿豆黄化幼苗在光照最初0.5h，单色光有利于Pchlide的还原和新Pchlide的生物合成；光照2h后，单色光不利于Chlide的酯化；CH明显抑制绿豆幼苗子叶Chlide的酯化速度，说明Chlide的酯化是受细胞核基因控制。
