The results showed with the increasing of NaCl concentration, the phenomenon of carnification could be found in the leaves of Arabidopsis thaliana . Under the stress of NaCl lower than 100 mmol/L, the tissue structure of root had no distinct difference from the control. When the concentration of NaCl was higher than 250 mmol/L, the stained color of safranine was deep but not even, and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue.

当NaCl浓度小于100 mmol／L时，根组织结构与对照未表现出明显的差异；但当NaCl浓度达到250 mmol／L时，根组织结构对番红染料的着色较深而且不均匀，维管组织和外围皮层细胞着色较深，而维管组织周围的细胞着色较浅。

After years studying the microscropic structure of plants, he proposed his cell theory Contributions to Phytogenesis(1838), in which he stated that the various plant structures are all composed of individual cells.

经过多年对植物显微结构的研究，他在1838年发表了的《植物发生论》中提出了细胞学说，指出细胞是构成植物体各种结构的基本单位。

Results The structures of the aloe leaves were basically similar as characterized by the presence of the large, well developed parenchymatous cells in the phloem pole where anthraquinones were stored. Some positive correlations exist between the contents of anthroquinones in the leaves of different species and different parts of leaves of the same species, and some phytotomic factors including the density of vascular bundles, the ratio of large parenchymatous cells in phloem and the thickness of the chlorenchyma.

结果 芦荟属植物叶的基本结构类似，维管束韧皮部内具大型薄壁细胞为该属的结构特征，是蒽醌类物质的主要贮存场所；不同种植物叶内及同种植物叶的不同部分中蒽醌类物质的含量不同与维管束分布密度、大型薄壁细胞所占比率及同化组织厚度成正相关。

This papers explore the correlation between the thickness of blade、cuticula、epidermis cells、fence form、sponge form,the ratio of the fence form and sponge form,the layer of the fence form,the length of cell and the yield,suitable system,resistance of the blade anatomical structure by paraffin section method and observing in optical microscope using tea varieties in Guangxi,such as the No.1 of Guilv, and provide a scientific basis for tea scientific research and production.

本文主要对近年来广西选育成的桂绿1号等新品种品系通过石蜡切片法，并采用光学显微镜观察叶片解剖结构特征，探索叶片解剖结构中的叶片、角质层、表皮细胞、栅栏组织、海绵组织等厚度及栅栏组织与海绵组织厚度的比值、栅栏组织层数、细胞长度等与产量、适制性、抗逆性之间的相关性，为茶叶科研、生产利用提供科学依据。

In the hypothesis, it is assumed that the photoreceptor outer segment is a cylindrical-like structure, while a photo enters the outer segment, the possibility of the impact between the photon and a photopigment molecule is maximal if the photon's travel path parallels to the axis of the cyclinder.

其理论系假设光感细胞的外节为一圆柱状结构，当光子进入到光感细胞的外节部分时，若其路径与此柱状结构的轴向平行，其碰撞到光色素分子的机率会最高，因此所产生的响应将最大。

Results: electronic microscope showed that in prednisone group heterochromatin increased in some cells, entoblast was not obvious in some cells, fat drops were small and few, mitochondria vacuole were common, and myelin figure was found in smooth endoplamic reticulum. the ultrastructure in yc group was almost normal and megamitochondrion formation was common. a large amount of fat drops were found in cytoplasm in gw group and little improvement was found compared with that in prednisone group.

结果： 电镜结果显示：激素组个别细胞异染色质增多，核仁不明显，脂滴显著变小变少，线粒体空泡化常见，有滑面内质网髓鞘样结构形成；养阴组电镜结构基本正常，其特征是细胞内有较多的巨大线粒体形成；桂附组较激素组改善不明显，其特征是胞质内可见大量脂滴。

The results are as follows:(1) The morphological investigation indicated that the nectaries werelacked on the main nervation, calyx and bract of cotton line 97014 comparedwith TM-1. Alveolate hollow was absent at main nervation of the mature leaf.Results of cytological analysis showed that 97014 lacked nectariferous structure.Where nectary inserted were parenchyma cells, cupped structure and brownnectariferous substance on the lower epidermis were not found.

主要研究结果如下：(1)以棉花无蜜腺品种97014与有蜜腺棉花遗传标准系TM-1为材料，进行形态学比较研究，结果表明棉花无蜜腺品种97014叶片中脉、花萼和苞叶上都缺少蜜腺，成熟叶片叶脉、花萼和苞叶上均无蜂窝状凹陷；组织与细胞切片观察发现，97014缺少蜜腺组织结构，在蜜腺着生处为排列整齐的薄壁细胞，且在下表皮看不到凹陷的组织结构和褐色的蜜腺分泌物。

Therefore, CRP could mediate E-LDL participating in the early stage of atherogenesis. CRP is an ancient conserved protein whose initial role as a pattern recognition molecule may have been to defend against bacterial infections, but whose present biological role appears quite complex. CRP is protective against a variety of bacterial infections and inflammatory stimuli as an opsonin. It is likely that the activity of CRP in humans is either pro- or anti-inflammatory is dependent on the context in which it is acting.

由于CRP的识别相可以结合被暴露出磷酸胆碱结构的E-LDL，形成E-LDL／CRP复合体，而内皮细胞表面能以高亲和力识别CRP的配体相，从而CRP-相性结构具有结合E-LDL，被内皮细胞捕获，引起脂质沉积和激活补体、触发炎症反应的可能性，这样可以解释早期动脉粥样硬化为何同时存在E-LDL、CRP、补体，而这三种物质在同时、同地出现绝非一个巧合。

It also provides protection of cell organelle and target sites from chemical or physical stimulations.

在纳米水平上研究细胞表面的基本结构及其受外界环境作用前后的变化，对于认识细胞表面结构与功能之间的关系，全面评价药效并对药物合成路线提供参考都具有重要意义。
