多倍体细胞

Until now,nine of the 12 euploid cytotypes of this polyploid complex have been found in the East Asian continent,which suggests the continent is one of the important locations where the cytotypic differentiation of the complex takes place.

至此在东亚大陆上已经发现该多倍体复合体12个整倍体细胞型中的9个。这表明东亚大陆也是该复合体细胞型分化的重要地区之一。

But, in the transformed MRC-9 cells, proportion of cells at G1 phase reduced to about 50％,and that at G2/M phase increased to over 20%and that of hyperploid cells to over 10％.

如未处理的MRC-9细胞，G1期为62.61%， G2/M期只有16.37%，几乎未见多倍体细胞，而在转化细胞中，G1期降到50％左右，G2/M期超过20％，多倍体细胞有的超过10％。

In summary, our results suggest that ANE increases micronuclei frequency, induces cell cycle arrest at G2/M phase, causes cytokinesis failure and accumulates hyperploid cells. The events are possibly associated with ROS production, actin filament disorganization and centrosome aberration.

故从本实验的结果，我们认为槟榔子萃取物会增加微核频，诱导细胞周期停滞於G2/M phase，造成细胞质分缺损与多倍体细胞的增多；而这些现象可能与活性氧的生成，actin filament 的常与中心体的变有关。

Therefore, the total cell number, floral structure and polyploidy pattern were not significantly affected. Our results indicated that systemic endoreduplication is intrinsically controlled by a differentiation program, and affected by environmental influences such as temperature changes.

结果显示内多倍体细胞的分布情形是分化过程中已经决定的，环境的变化并不会明显影响倍体数细胞分布形式。

A polysomic individual; a polysomic cell.

Two populations (located at Sanhu town,Xingan co.,Jiangxi province) of Scilla scilloides polyploid complex were surveyed cytologically,and four cytotypes,BB,BBB,BBBB,and ABBB were observed among two hundred and sixty three individuals.

对来自江西省新干县三湖镇绵枣儿多倍体复合体两个居群263个植株进行了细胞学调查，发现4个整倍体细胞型，即BB、BBB、BBBB和ABBB。

Polytene chromosome structure is a characteristic of some polyploid cells where several to thousands of chromatids are closely associated with perfect alignment of homologous DNA sequences.

多染色体结构是多倍体细胞的特征。在多倍体细胞中，有几个至几千个染色单体与相对应的DNA序列精确结合。

The clinic studies show that Jujing Pill can increase obviously the spermatozoa's density of the oligospermatism patients and the astheno-spermia's spermatozoas's energy,live ratio,the forward moving speed;decrease the deformed spermatozoa's ratio of the deformity of sperm;increase obviously the percentage of normal monoploid spermatozoas in the male infertility patients;decrease the percentage of the abnormal polyploid spermatozoas.

临床研究表明，聚精丸能明显增加少精子症患者的精子密度，提高弱精子症的精子活力、活率及精子向前运动速度，降低畸形精子症患者的精子畸形率，显著提高男性不育症患者精液中正常单倍体精子的百分率，降低异常的多倍体细胞的百分率。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
