成红细胞

Red blood cells were imged by AFM and the typical biconcave shapes were observed . The ultrastructure of RBC membrane was also gained. Themorphological changes of red blood cell membrane after the interaction of trichosanthin were clearly observed by AFM.

对红细胞进行成像，观察到红细胞双面凹的典型特征，小范围扫描观察到了红细胞膜表面的超微结构，在此基础上研究了红细胞与天花粉蛋白作用后红细胞膜表面超微结构的变化，并对二者作用的机理进行了分析讨论。

On the basis of observation on the denucleation process of mammalian erythroid cells in vito and in vitro, the present study was designed to investigate the regulatory effect and its mechanism of mammalian erythroblast cytoplasmic factor on malignant phenotype and gene expression of hybrid cells formed by cellular engineering fechnique of cell hybridization between the mouse plasmocytomas SP (2/0) cell line and rat erythroblasts.

本研究选用正常大鼠中幼、晚幼成红细胞与小鼠浆细胞瘤（SP2/0）细胞进行异种细胞杂交，研究哺乳动物红细胞胞质因子对肿瘤细胞恶性调控的效应及其机制。

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。

A patient in shock, who had been given a transfusion in excess of the normal capacity of his circulatory system, sometimes developed polycythemia.

一个休克病人，如果得到大于他血液循环系统的正常容量的输血，有时会发展成红细胞增多症。

Using this method, we can obtain about 96% of hemogenous population of intact and viable intermediate and late erythroblasts.

从70%Percoll梯度介面（比重为1.095g/ml）可收集到纯度高达96%的中幼、晚幼成红细胞。

Drugs and toxic agents may interfere with the appropriate utilization of folic acid and cause a megaloblastic anemia.

药物与毒物在适当利用叶酸时，而可能引起巨成红细胞性贫血。

Drugs and toxic agent s may interferewith the appropriate utilization of folic acid andcause a megaloblastic anemia.

药物与毒物在适当利用叶酸时，而可能引起巨成红细胞性贫血。

Studies on the regulation of malignant phenotype expression in a mouse plasmocytoma cell line (SP2/0) by means of cellular engineering techniques of cell hybridization between the fusion of the mouse myeloma cells with rat intermediate or late erythroblasts.

三、利用细胞杂交的细胞工程手段，首次系统地研究了大鼠中幼、晚幼成红细胞与小鼠浆细胞瘤（SP2/0）细胞融合后恶性表型的表达状态，分析自然去核前红细胞胞质对骨髓瘤细胞恶性增殖的调控作用，以及晚幼期固缩核重新被激活的可能性。

Trypan blue vital staining demonstrated that there were over 95% of the cells maintained viable after separation.

台盼兰活体染色检查表明：分离后的中幼、晚幼成红细胞保持95%以上的活性率。

Any of the nucleated cells normally found only in bone marrow that develop into ''.

成红细胞，有核红细胞一种有核细胞，通常仅能在骨髓中发现并能够发展成为红细胞或红血球

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
