The tumor is sessile, polypoid, or castlike and is characterized by the presence of innumerable papillary frondlike infoldings comprised of proliferations of columnar epithelial cells around the slender fibrovascular stalks that are supported by the connective tissue of the lamina propria.1 Occasionally, tumor spreads superficially along a variable length of the bile duct.

该肿瘤是无蒂、乳头样或脱落物样的，以及肿瘤表面特征性地存在无数乳头样叶状内折叠，这些乳头是由围绕纤细的以管腔的结缔组织为支撑的纤维血管茎增殖的柱状上皮细胞构成。肿瘤偶尔也会沿不同长度在胆管表面蔓延。

In this study, we found that fluorene induced angiogenic effects by cell adhesion, cell migration, and tube formation assays.

结果发现芴会促进细胞黏附、移行以及管状形成作用。

Results By using zinc-iodide-osmium staining, the tubulo-vesicular system of parietal cells of fundic gland was manifested as numerous fibrous structures under HVEM. The nematolysosomes was often demonstrated as branching in shape and anastomosed with each other making a network system in cytoplasm under the visual field of the three dimensional electron microscopy combined with AcPase cytochemistry.

结果高压电镜下显示，锌-碘-锇酸染色方法制备的标本胃底腺壁细胞的微管泡系统呈无数纤维状结构；AcPase结合三维电子显微镜观察显示，线性线粒体在胞质中常呈分支状并互相吻合成网。

At 12 weeks after surgery, calcium deposited in bone trabeculas, with a Haversian canal in the center, canal of bone opening in inner wall and lamellar bone arranged in periphery in the experimental group.

术后12周实验侧骨质排列有序，胶原粗大排列整齐，大量骨细胞方向有序，大量钙盐沉积，可见哈佛氏管和血管。

Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。

The interfascicular cambium and INTRAFASCICULAR CAMBIUM link into a complete cambium cylinder that cuts off secondary xylem tissue to the inside, secondary phloem tissue to the outside, and parenchyma cells both sides.

束间形成层和束中形成层组成一个完整的形成层环。形成层以内为次生木质部，形成层以外是次生韧皮部。薄壁组织细胞形成维管射线。

Furthermore, cells in different living stages responded to the treatments (Oryzalin and Ca〓) differently, young active internodal cells seemed to be more sensitive.

并且不同生长状况的节间细胞内的微管骨架，对Ca〓和Oryzalin处理敏感性表现也各不相同。

BSA can induce ACE up-regulation in proximal tubular cells, which may lead to the increased production of local AngⅡ and finally contributes to the intrarenal activation of renin angiotensin system.

BSA可显著增加HK-2细胞ACE表达，此作用可能是导致肾间质局部AngⅡ蓄积从而启动肾小管间质纤维化的重要机制之一。

Eight weeks latter, the left testes were harvested for detection of Johsen's score, ultrastructure of seminiferous tubules, intratesticular testosterone concentration and germ cell apoptotic index.

于VT8周后摘取各组大鼠左侧睾丸，检测其Johnsen's评分、生精小管的超微结构、睾丸组织的睾酮浓度和生精细胞的凋亡指数。

Nerve guidance Netrins play major roles in neuroal growth and angiogenesis. Netrin-1 plays positive effect in the vascular formation process from endothelial cells of human artery and microvessel before karyomitosis, adherence and migration.

其中神经导向因子Netrins不仅参与神经的生长还参与血管新生，Netrin-1对人动脉和微脉管系统初期不同内皮细胞的促有丝分裂前、粘附前和迁移前有积极效应。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
