无丝分裂

The results revealed that two cases of amitosis existed in acute myeloid leukemic cells.

结果发现在 2例标本中存在白血病细胞的无丝分裂现象。

The corneal endothelial cells of the primate have regenerative power, and the form is amitosis.

灵长目动物角膜内皮细胞在一定条件下有再生能力，其再生方式为无丝分裂。

The regenerative form of corneal endothelial cells of the adult, infant and fetal primate was amitosis under both physiologic and pathologic conditions.

成年及幼年灵长目动物角膜内皮细胞在生理和病理条件下的再生方式均为无丝分裂。

Cell fragmentation is a mainly amitotic way in early cultured PC 12 cells.

细胞裂殖是早期培养PC12细胞的主要无丝分裂方式。

In prokaryotes the nuclear material is simply a circular strand of DNA, not complexed with histone proteins, and cell division is amitotic.

在原核生物中，核物质仅是一个简单的环状 DNA ，而不与组蛋白结合，并且细胞为无丝分裂。

Results: PC12 cells exhibited amitotic figures including circular shrink, sideways concave, etc.The figures of asymmetric division in shape, size and the cell chemical properties by staining and the cell enucleation were observed.

结果：PC12细胞呈现横缢型和侧凹型等无丝分裂像，并且观察到其形态、大小和化学性质的不对称性分裂及细胞脱颖现象。

The neurons differentiated by NGF in cultured PC12 cells can divide in amitotic way.The differentiated neuron can form junction by cell migration, neurite extension or cytoplasmic bridge.

NGF诱导PC12细胞分化的神经细胞能以无丝分裂方式增殖；分化神经元可以通过细胞迁徙、突起延伸及共同胞质桥等方式相连接。

The proliferating cells were mainly distributed in the peri-chondrium and the peripheral zone of tracheal cartilage. The senescent chondrocytes were distributed in the central zone whereapoptotic morphological characteristics obviously appeared, such as pyknosis, karyorrhexis.

结果：软骨细胞呈现多种方式的无丝分裂像；气管软骨膜与软骨周围带多见细胞增生；气管软骨中央带多见衰老的软骨细胞，并见明显核固缩、核碎裂等细胞凋亡形态学特征。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
