①At the 8 weeks of fetalage, the ciliated, small mucous granule cells and rare basal cells were all differentiated from endoderm cubic cells, which was 3 weeks earlier than Gaillard's report.

①人胚胎8周时，内胚层细胞已分化出气管上皮的纤毛细胞、小粘液颗粒细胞、基底细胞很少，该结果比过去Gaillard等的报告提前3周。

Methods: Parallel-plate-flow-chamber was used to assay the influence of shear stress on endothelial cells morphology and cytoskeleton and apoptosis and NO secretion. endothelial cells morphology was observed under microscopy, cytoskeleton was showed by Coomassie brilliant blue staining, fluorescence stain, and transmission electron microscopy, apoptosis was detected by FCM, NO of circulating culture medium was assayed by NO kit.

细胞形态显微镜下直接观察；细胞骨架通过考马斯亮蓝染色、荧光标记和透射电镜进行观察；细胞凋亡通过流式细胞仪检测进行分析，一氧化氮通过流动循环培养基的收集后应用检测试剂盒进行检测分析。

The cells are typically platelike and closely packed together except where they are modified for a particular function, as are guard cells.

表皮细胞是很有特色的一个细胞层，除了某些具有特殊功能部分细胞，如保卫细胞外，通常都紧密的排列在一起。

We also discovered that selenium can decrease hematolysis and effects function of vacuole toxin of HP. morphological conversion from spiralto coccoid forms occurredwhen HP was caltured with selenium and most of coccoid forms had fragmentary flagella and pilus; the effection of selenium to activity of urease, catalase, alkaline phosphatase is not exist or not evidence; selenium enable pET32a-vacA-E. coli BL21 which can express VacA produce yellow lipochrome, and the color become deeper with increasing of concentration of selenium; selenium can decrease expression of recombined VacA by restrain the growth of pET32a-vacA-E. coli, but can not influence activity and gene equence of VacA; selenium can enhance the suppression effect of recombined VacA for gastric cancer cell, depress the index of cell multiplication and the forming rate of colony, decrease the number of cell in S period, increase total of cell in G period; After purified, the recombined VacA can be identified by VacA antibody.

结果：体外实验结果表明：一定浓度的硒作用HP后，HP菌落数量随着硒浓度的增加而减少，菌落颜色由灰白色变为砖红色，溶血现象随硒浓度的增加和作用时间的延长而逐渐消失，HP的形态由弯曲形变为球形或椭圆形，鞭毛及菌毛出现脱落现象；硒对尿素酶、过氧化氢酶、碱性磷酸酶活性无影响或影响不明显；一定浓度的硒能使表达VacA的pET32a-vacA-E.coli BL21工程菌产生脂溶性砖红色色素，颜色随硒浓度增加而加深；一定浓度的硒通过抑制pET32a-vacA-E.coli BL21工程菌的生长，减少重组VacA表达量，但不影响其空泡毒活性及编码基因序列；硒能增强重组VacA对胃癌细胞的抑制作用，使细胞分裂指数和集落形成率降低、S期细胞数量减少，G1期细胞总数增加；纯化后的VacA重组蛋白可被VacA抗体识别，具有良好的抗原性。

Subcellular localization of ATPase activity in the flesh of developing apple fruit was carried outusing a lead phosphate precipitation technique via electron-microscope. The ultrastrcture of phloemand its surrounding cells was also observed. The results showed that ATPase activity wasdominantly localized on the plasma membranes of sieve element/companion cell complex.

应用铅沉淀的细胞化学方法，研究了发育过程中苹果果肉内卸载区(韧皮部及其周围薄壁细胞)ATP酶的亚细胞分布和变化，并且，作为补充，观察了韧皮部及其周围薄壁细胞的超微结构。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The students read texts to obtain the microscope-related concepts which included the following: making water mount specimen to be observed by depending on the correct steps, the image of object shown on compound microscope was enlarged directly by the specimen; some differences of structure were found both plant cell and animal's cell, animal's cell does not have cell walls and chloroplasts, it unable to photosynthesis; small living beings of water, consumers, will eat little small living beings.

学生由阅读文章而获得的细胞相关概念主要有：能依正确的步骤，制作一个水埋法标本片进行观察，在复式显微镜下观察到的影像和实物是左右相反、上下颠倒的，植物细胞和动物细胞的形态及构造有些差异，动物细胞不具细胞壁、叶绿体，无法行光合作用，有些水中的微小生物会摄食更小的微小生物，是消费者。
