细胞分裂

Amitosis began with a transversal constriction of nucleus to form dumb bell shaped nucleus which later split into two daughter nuclei, and completed with the separation of cytoplasm to form two new cells.

无丝分裂过程先是细胞核中部缢缩形成哑铃状细胞核，然后分裂成两个子细胞核，最后细胞一分为二、完成细胞分裂。

Both the new peniculus 1 and the old haplokinety separated at the telophase.The two germinal rows germinal rowsfor both the daughter cells appeared almost at the same time;(2) The macronucleus became shorter and thicker, finally oblate during the division of the cell. Then the macronucleus restored its original shape, band-like form. The micronucleus were divided into two before the macronucleus division;(3) The original scopula and stalk contributed to the old cell. The new cell formed scopula gradually after the cell division.

同时，新仔虫的第一咽膜(P′1)也开始由老单毛基索复制，并在细胞分裂后期与老结构分离；(2)大核在虫体分裂过程中由长带状逐渐缩短变粗至扁圆形，于虫体即将分开时迅速拉长，然后分裂为二个新大核；小核分裂先于大核，在两仔虫口纤毛器即将分开时完成；(3)原帚胚及柄归属老仔虫，新仔虫的帚胚在虫体分裂后逐渐形成，柄内肌丝则在柄鞘形成后逐渐长出。

This coupling of cell division and cell survival is unique – other genes that promote cell division, for example, Myc, also sensitize a cell to death.

这种促进细胞分裂和细胞生存的作用的偶联是唯一的——其它能促进细胞分裂的基因如Myc，却会促进细胞的死亡。

Telophase The final stage in mitosis and meiosis, in which the separated chromatids or homologous chromosomes of bivalents collect at the poles of the spindle and the nuclei of the daughter cells are formed.

细胞分裂的末期：是细胞的有丝分裂和减数分裂的终极阶段。在这个时期内，分离的姐妹染色单体或二价体的同源染色体向纺锤体两极聚拢，同时子代细胞核形成。

Results In animal study, lumbricus could inhibit the growth of staphylococci, bacillus coli and bacillus aeruginosus. The time of wound healing in experimental group was 4 days shorter than that in control group. At 4d and 7 day the numbers of the capillary, blood vessel endodermis and desmohemoblast desmocyte and splitting epithelium of trial group were much more than those of control group. At 4d the trial group′s numbers of splitting mesenchymal cell were much more than that of control group. From 3d on the wound healing and granulation filling of experimental group were much quicker than those of control group.

结果 动物实验中，地龙能抑制金黄色葡萄球菌、大肠杆菌及绿脓杆菌的生长；实验组创面愈合时间较对照组提前了4天；第4、7天实验组动物创面的毛细血管数、血管腔内皮细胞数及间质成纤维细胞数均较对照组明显增多，上皮细胞分裂象也高于对照组，第4天的间皮细胞分裂象也高于对照组；自第3天始创面愈合及肉芽充填速度实验组明显快于对照组。

In this study, we investigate how the cell cycle coordinates gastrulation cell movements in zebrafish.

一方面是细胞分裂/细胞周期，通过无数次的细胞分裂，胚胎发育从一个单细胞受精卵发育为多细胞成体。

In nonclinical studies, normal cells appear to beable to recover from intermittent proteasome inhibition, but many types of cancercells undergo apoptosis when proteasomes are inhibited, even for a short time.

它可以选择性地抑制蛋白酶小体的苏氨酸蛋白酶活性，减少对特定细胞周期调节蛋白(IkB、p53、p27、p21等)的降解。由于这些调节蛋白的集聚，肿瘤细胞分裂周期受到干扰，细胞分裂停止，最终导致细胞凋亡。

The incompatible results have been reported even with the same methods But these studies were carried out on the basis that the structure of nucleolus is regarded as a static state. However, the nucleolus is a highly dynamic structure during the cell cycle. It disassembles in the late prophase and reassembles at the end of mitosis.

不过以前对核仁结构和功能的研究大多只是对细胞间期中某个时期细胞的核仁进行静态研究，然而核仁是一个高度动态变化的结构，在细胞分裂前期解体，在细胞分裂末期又开始重建。

It was demonstrated that DPU itself acted as a kind of cytokinin in delaying senescence. However, it also postponed the decline of endogenous cytokinins of half-fronds.

实验结果表明，二苯脲本身具有细胞分裂素的活性，能代替内源细胞分裂素起到抗衰老的作用；二苯脲同时也能推迟半叶状体中内源细胞分裂素含量的降低。

It is zeatin that mainly determines root activity and sustainleaf physiological function.However,not every kind of cytokinins hasthe capacity to promote or keep physiological function.Some kinds ofcytokinins are related to senescence.

决定根系活力和维持叶片生理功能的细胞分裂素是玉米素，但是，不是每一种细胞分裂素都有促进或保持生理活性的作用，部分种类的细胞分裂素很可能与器官的衰老有关。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
