胞质

Institute of Botany, the Chinese Academy of Sciences, Beijing 100093Abstract Plasmodesma is a supracellular structure of plant organism. It provides a direct cell-to-cell cytoplasmic pathway for material transport and message transference, and converts the colonies of independent cells into an interconnected symplast system.

胞间连丝为多细胞植物有机体提供了一个直接的细胞间物质运输和信息传递的细胞质通道，把一个个独立的"细胞王国"转变成相互连接的共质体，它是当今细胞生物学中十分活跃的研究领域。

胞间连丝是植物体的一种超细胞结构(supracellularstructure ，Lucasetal，1 993 )，它把一个个独立的"细胞王国"转变成相互连接的共质体，为植物体的物质运输和信息传递提供了一个直接的从细胞到细胞的细胞质通道。

Results Cvb-D obviously lightened isoprenaline-induced myocardial pathological changes such as turbulence of myocardial fiber, plasmolysis of necrotic cell, inflammatory cell infiltration of necrotic interstitial region. Cvb-D remarkably inhibited myocardium cell apoptosis of myocardial ischemia rats caused by isoprenaline.

结果 Cvb-D可显著减轻Iso诱发的心肌缺血致心肌肌纤维排列紊乱，坏死细胞胞泉溶解，坏死间质区炎性细胞浸润等病理改变；Cvb-D可显著抑制Iso诱发的心肌缺血性模型大鼠心肌细胞凋亡。

In the biotechnology area, we has set up polytype Handson yeast express system which owned freedom intellectual property rights, including:(1) URA3 - defective nutrition host cell strain HU-II;(2) secretion and intracellylar expressing plasmid carrier pMPT-01、pMPT-02;(3) a platform for semi-works

在生物技术领域：建立了拥有自主知识产权、较为完善的多型汉逊酵母表达系统，包括：（1）URA3 -营养缺陷型宿主细胞株HU-II；（2）分泌型和胞内型表达质粒载体pMPT-01、pMPT-02；（3）汉逊酵母细胞电穿孔转化操作程序及多拷贝、稳定化整合转化子筛选程序；（4）中试生产规模的发酵和纯化平台。

Perianth (3 to)5-parted, succulent or herbaceous; utricles flattened, rarely only compressed, without beak; plant body without ramified hairs.

Perianth(3 对)5深裂，多汁的或草质；胞果扁平，很少只压缩，没有具喙；植株身体没有使分支的毛。

These were low-differentiated cells. Growth curve of cultured MSCs was "S" shape. The first, third and fifth passage cells had strong reproductive capability.

透射电镜观察显示间充质干细胞核大，以圆形或类圆形为主，胞核比例大，细胞器少，为低分化细胞。

The cell wall of sclerenchyma in ROL barrier was significantly thickened in conventional lowland rice (Yangdao 6) with the increase of PEG concentration, but upland rice (Zhonghan 3) was not sensitive to low PEG concentration. The thickening of ROL barrier obviously became stronger at 50 g·L-1 and higher concentrations. Besides, suberisation of cell walls increased significantly with the time extension.

随PEG浓度的升高，水稻(扬稻6号)根的ROL屏障厚壁细胞胞壁宽度明显增加；旱稻(中旱3号)对低浓度PEG胁迫不敏感，当PEG浓度达50 g·L-1以上时，ROL屏障厚壁细胞才表现出明显加厚的趋势，且随PEG胁迫时间的延长，厚壁细胞栓质化程度变高。

The iron replacement of sillimanite may somewhat affect the physic-chemical calculation and exert negative effects on sillimanite mineralization.

铁组分的类质同像替换对物理化学计算和夕线石矿化环境均有所影响，对夕线石晶胞参数a的影响很小，而对b，尤其对c的影响较大，与前人的结论有所不同。

Concentrations of DA and 5-HT in different regions were measured by high performance liquid chromatography; the expression of SERTmRNA was detected by in situ hybridization; the degeneration of neuron and terminal was demonstrated by Bielschowsky and Glee Marsland silver staining; and the protein expression of GFAP was detected by immunohistochemistry.

2采用高效液相色谱法测定不同脑区神经递质DA和5-HT的含量；采用原位杂交方法检测SERTmRNA；Bielschowsky及Glee Marsland氏改良银浸染法显示神经元胞体、树突和轴突；免疫组织化学方法检测GFAP的表达。

By using shape analysis,stereoscopy and moment of image,a number of eigenquantumwere extracted,such as radial diameter,tangential diameter,length and area of lumen,complexof cell,comers of edge and convex-concave properties.At the same time,the algorithm ofextraction and statistical analytic methods of pattern features were put forward.

利用形态分析、体视学及图像的矩来提取如早、晚材细胞的径向、弦向直径、管胞长度、面积、密质度及边缘的角、凹凸性等特征量，并提出了这些模式特征的提取算法和统计分析方法。

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％。
