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。

Result:TNF-α was localized in the epitheliun and connective tissue of cholesteatomas studied, particularly on basal and spinous cells and macrophages.

结果：TNF-α定位于胆脂瘤组织的上皮及上皮下结缔组织，较正常外耳道及鼓膜的染色明显增强。

All kind of structure changes do not occur at the same time, for example the epithelial desquamation occurring after exposure for 1 week and sub- epithelial fibrosis occurring after exposure for 8 weeks, and it is incomplete that the prevention of inhaled corticosteroids on airway remodeling. So inhaled corticosteroids should be introduced to treat asthma as early as it possible.

5哮喘气道重塑过程中，气道结构的各种改变是不同步的，气道上皮脱落在激发1w后即可发生，而上皮下纤维化在激发sw后出现，且ICS对气道结构改变的防治是不完全的，故临床上应及早使用ICS治疗，并结合其他抗炎剂如白三烯受体拮抗剂以最大程度地防治气道重塑的发生。

Background: Subepithelial hypervascularity and angiogenesis in the airways are part of structural remodelling of the airway wall in asthma, but the effects of inhaled corticosteroids on these have not been explored.

背景：气道上皮下血管过度形成及血管发生是哮喘患者气管壁结构重建的一部分，但是吸入型糖皮质激素在这方面的作用并没有被研究。

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.

结果HE染色：翼状胬肉组织上皮下基质中存在结缔组织的增生和血管形成；基质浅层存在一无定形物质透明区及粗糙的颗粒样嗜酸性物质，在翼状胬肉体部深层基质中存在粗糙的纤维组织；正常球结膜组织细胞排列整齐；基质为疏松结缔组织，胶原纤维平行排列，其间可见成纤维细胞，散在少量中性粒细胞、毛细血管；Masson染色：翼状胬肉浅层基质中存在致密的胶原纤维染色，深层基质中的胶原纤维存在变性样改变；VG染色：翼状胬肉组织深层基质中存在大量变性的胶原纤维，其间夹杂黑色的弹性纤维；免疫组化染色法：MMP-3在翼状胬肉上皮细胞中呈强表达，成纤维细胞中呈中等强度表达，血管内皮细胞中未见表达；LN在血管壁中呈强表达，在上皮细胞基底膜中呈中等强度表达，在整个基质中未见明显表达；col Ⅲ在整个翼状胬肉基质中呈强表达。

Corneas and subbasal nerve fibers were examined by confocal microscopy at 1 day, 1 week, 1 month, 3 months and 6 months after the operation.

手术患者分别在术后1d、1周、1个月、3个月、6个月时行角膜共焦显微镜检查，比较两组患者术后角膜上皮下神经纤维再生的情况。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
