Then, the volume and morphology of grafts were observed and proliferating cell nuclear antigen expression of mammary epithelial cells in grafts was detected by immunohistochemistry. Experiment two: From 2 to 6 weeks after implanting, B-E〓 or NH1996 with respective dosage of 20ug and 100ug were injected muscularly into four groups of host mice once two days, and the control group was designed without treated with hormone.

结果：1。植入2周和6周乳腺组织形态结构保持完整，植入2周乳腺组织块体积、腺体数目和增殖程度均较植入时明显降低，并以此水平维持至植入6周。2.B-〓对植入的乳腺组织形态学无明显影响，但可引起乳腺上皮细胞PCNA、Bcl-2蛋白表达的升高；B-〓可上调PR，下调ER，说明植入裸鼠的正常乳腺对B-〓有反应，证实模型建立成功。

By in situ hybridization, 53BP2 mRNA expression is revealed in tumor cell nests of NPC paraffin sections. The strong positive particles localize in the nuclei of tumor cells; but slight positive signals are also found in tissue cells of chronic nasopharyngitis and connective tissue, such as lymphocytes and smooth muscle cells; There are also positive signals in the nuclei of hyperplastic squamous epithelial cells. However, 53BP1 mRNA expression is not found in nuclei of tumor cells, tissues of chronic nasopharyngitis and connective tissue.

原位杂交结果显示，石蜡切片的鼻咽癌癌巢内，可见53BP2的强阳性表达信号，信号呈紫色颗粒状分布于胞核，核仁清晰可见；而在相同条件下，在慢性鼻咽炎组织和癌旁上皮的结缔组织，也可见弱表达信号，如淋巴细胞和平滑肌细胞；在增生的鳞状上皮细胞的核内，可找到强阳性信号。53BP1在鼻咽癌、慢性鼻咽炎组织和癌旁上皮的结缔组织切片上，均无表达信号。

The three species shared a few common features in the palisade-like epithelial cells, vascular supplies, and nectary openings. However, they showed some differences in longitudinal section and transectinal outline.

这3种植物花蜜腺的栅栏状表皮细胞、维管束和蜜腺开口方式相似，而从纵切面和横切面上观察其结构存在一些差异。

In conclusion, the current work has shown that NPY and AChE may originate from epithelial cells, the distribution of NPY, AChE have a close relation with behavior, regeneration and morphogenesis of Hydra pseudoligactis, NPY plays a role in development and differentiation of nematocyst, and ACh may function in emission of nematocyst.

水螅刺丝囊的分化和发育与NPY的作用密切相关；刺丝囊发射刺丝的机理与胆碱能的作用可能有联系[动物学报52(1)：115-122，2006]。

Objective To investigate the effect of IL-18 on proliferation and apoptosis of renal tubular epithelial cells, and then to demonstrate its role in the progression of chronic nephrosis.

目的 探讨白细胞介素18(IL-18)对肾小管上皮细胞增殖及凋亡的作用以进一步明确其在慢性肾病进展中的作用。

The releasing pattern of secretory granules or polypeptide hormones of neurohypophysis involves a whole-releasing pattern together with granular membrane. After released into perivascular space, they enter easily into cerebrospinal fluid via interspace of tissue and epithelial openings rather than into blood circulation through the walls of capillaries, and then into the cerebrospinal fluid.

神经垂体多肽激素分泌颗粒的释放形式，存在一种连同颗粒被膜的整体释放；释放入血管周隙内的多肽激素或分泌颗粒，更易经组织间隙、囊上皮孔进入脑脊液，而非直接透过毛细血管壁进入血液循环再进入脑脊液中。

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。

CONCLUSIO : It is a ropriate to use noncellular features such as clinical and imaging findings as adequacy criteria for breast FNA rather than identification of a minimal number of ductal epithelial cells.

但是NCI推荐的乳腺FNA 不满意上限20%并不适用于乳腺保健诊所，因为这种操作中的损伤会导致不合适样本的增加，引起对于质量的不必要关注。

Methods SP immunohistochemical staining was used to detect the level of VEGF and EG-VEGF in 85 cases of the epithelial ovarian tumor tissue(25 cases of benign tumor,27 cases of ovarian carcinoma of stage FIGOⅠ、Ⅱ,33 cases of ovarian carcinoma of stage FIGOⅢ、Ⅳ)and 20 cases of normal ovarian tissue.The integral optical density was measured.

方法应用免疫组织化学SP法和形态定量学方法检测85例卵巢上皮性肿瘤(良性25例，FIGOⅠ、Ⅱ期卵巢癌27例，FIGOⅢ、Ⅳ期卵巢癌33例)和20例正常卵巢(除外卵巢疾病的绝经前患者)组织中VEGF、EG-VEGF表达的阳性率及积分光密度值。
