The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.

结果：(1)层粘连蛋白组处于G_2～M期细胞比例较对照组显著提高，Go～G_1期细胞比例显著下降，提示层粘连蛋白促进内皮细胞DNA合成，及细胞分裂增殖；光镜下，对照组细胞分布成团状，细胞密度较低，细胞间连接紧密，细胞内微丝结成网状，细胞核大小一致；与对照组相比，层粘连蛋白组细胞生长旺盛，细胞密度高，向周边伸出大量板状及丝状伪足，细胞内微丝增多、拉长、集结成束，伸入伪足中，细胞核形状大小不一致；(2)倒置显微镜观察及细胞生长曲线显示，各组细胞数目随时间增加而明显增多，各实验组较对照组增生显著，EGF和LN联合应用组各时间点细胞数目最高；实验组处于S期和G_2～M期细胞数目增加，Go～G_1期细胞数目减少；提示EGF、LN单独及联合应用均可促进细胞增殖，但尚不能认为二者有交互作用；(3)倒置显微镜下，组织培养的猫角膜内皮细胞排列成密集的单层，细胞间连接紧密；组织学观察发现，培养的猫角膜内皮细胞形成完整的内皮层，贴附于脱水基质的后弹力膜上，与正常的角膜内皮组织结构相似；扫描电镜下，组织培养的猫角膜内皮细胞间紧密镶嵌排列，可见某些细胞呈近似六边形排列，细胞大小不甚一致，胞核清晰。

YR-cohesion chromosome model will give a better answer to the questions such as exchange,centromere,holocentromere,synaptonemal complex,polytene chromosome,puff,lampbrush chromosome,chromosome banding,non-segregation of sister chromatid,pollentube pathway and biological evolution.

YR-染色体模型能自然、合理地解释所有遗传现象，如交换、着丝粒、全身着丝粒或弥散型着丝粒染色体、同源染色体联会及联会复合体的中央区、多线染色体与膨突、灯刷染色体、染色体分带、姊妹染色体由前期到中期不分开、花粉管会导入外源遗传物质、高等生命是怎样从原始生物进化而来的等等。

The relationship between MFs and MTs in the organization of PPB was investigated in garlic root tip cells subjected to treatment with cytochalasin D , latrunculin A and phalloidin .

用微丝特异性解聚药物（细胞松弛素CD和LAT A）以及微丝稳定药物处理大蒜根尖分生组织细胞的实验结果表明：微丝被破坏后，导致了早前期微管带宽度明显增加，Ph处理则对早前期微管带的宽度无影响。

Optimal conditions for labeling MFs were tested. Best images were obtained with low fluorescent phalloidin concentration and shorter fixation time. 10nmol/L fluorescent phalloidin was found to be the optimal concentration for MFs localization in BY-2 cells.The distribution of MTs and MFs array in tobacco BY-2 suspension cells during the cell cycle were investigated with confocal microscopy.

采用间接免疫荧光定位及荧光定位技术结合激光共聚焦扫描显微镜等技术，对烟草BY-2悬浮细胞周期中微丝标记的最佳条件、微管列阵与微丝列阵的分布状况进行了研究，结果表明：10nmol／L荧光鬼笔环肽是活体细胞标记微丝的最佳浓度。

Assessment with a pressure wire also did not add time to the procedure, which took an average of 70 minutes using conventional angiography and 71 minutes with the pressure wire, probably because of the time saved in placing an average of one fewer stent per patient.

此外，采用压力导丝进行评价并不会延长手术时间，采用传统的血管造影术平均需要70 min，而采用压力导丝也只需要71 min，这很可能是因为采用压力导丝，每例患者可平均少用1个支架，从而节省了部分时间。

While the Addis hypothesis of work hypertrophy to excrete urea is erroneous, a more modern concept associated with glomerular hyperfiltration was proposed in the 1980s by Brenner.25 This hypothesis states that after any significant loss of renal function, surviving nephrons subsequently undergo functional and structural changes including increases in single nephron GFR and glomerular capillary pressure increases.

当Addis成果假设过度膨胀分泌尿素的观点是不正确的，Brenner在1980年代提出了有关肾丝球体高滤过率的最新观点25。这个前提陈述，在肾脏功能有任何显著的丧失之后，幸存的肾脏小过滤器也接著经历了机能上和构造上的改变，包含增加了一单位小过滤器的肾脏丝球体过滤率和提高肾丝球体毛细管压。
