纤毛

Results:(1) Progesterone-treated models showed intact nasal mucosa, regular ciliary lining and inactive glands;(2) Untreated or normal saline treated models showed disrupted mucosa, inverted cilia and massive mucosal infiltration of neutrophils;(3) Smearing of nasal discharge revealed limited vs abundant number of neutrophils in SD models treated with progesterone vs untreated or treated with normal saline.(4) Hoechst stain: significantly fewer apoptotic cells per field were found in progesterone-treated models (1.583 ± 0.28) compared with untreated or normal saline treated models (2.85 ± 0.285 and 4.8 ± 0.715, respectively).

结果：(1)用黄体酮滴鼻液治疗的SD大鼠鼻腔黏膜上皮完整，纤毛整齐，腺体开放不多；(2)用或不用生理盐水滴鼻液治疗的SD大鼠鼻腔黏膜上皮纤毛倒伏，上皮结构散乱，上皮层大量中性粒细胞浸润；(3)鼻腔分泌物涂片示黄体酮滴鼻液治疗的SD大鼠有少许中性粒细胞，而用或不用生理盐水滴鼻液治疗的SD大鼠鼻腔分泌物含有大量中性粒细胞；(4)Hoechst染色：用黄体酮滴鼻液治疗的SD大鼠鼻腔黏膜上皮凋亡细胞数［(1.583±0.28)/视野］明显少于用或不用生理盐水滴鼻液治疗的SD大鼠［分别是(2.85±0.285)/视野和(4.8±0.715)/视野］。

Results AQP1 is expressed at the apical and basolateral membrane of the microvascular endothelium; AQP3 was detected at basal cells of both the bronchiole epithelium and submucosal gland acinus; AQP4 is present in the basolateral membrane of columnar cells in bronchiole; while AQP5 is expressed in the apical membrane of type Ⅰ pneumocytes, and also at the apical of columnar cells of superficial epithelium and submucosal gland acinar cells.

结果本研究发现AQPs基因在羊肺中的表达分布与人相似，AQP1在肺内的毛细血管内皮细胞表达；AQP3在小支气管黏膜上皮的基底细胞的基侧膜表达，AQP4存在于小支气管黏膜上皮的柱状纤毛细胞的基侧膜；AQP5存在于Ⅰ型肺泡上皮细胞的顶质膜，存在于小支气管黏膜上皮柱状纤毛细胞，以及在气道黏膜下腺的腺细胞的顶质膜表达。

But the intensity is much weaker than positive control with deoxysodium cholate. Conclusion Ditong nasitis drop had no remarkable effect on injuring the function of frog mucosa cilia.

滴通鼻炎水在整体实验和离体实验中对蛙黏膜纤毛的功能无明显影响，但滴通鼻炎水浸润30 min后对黏膜纤毛运动有抑制作用。

The frontal cilia and the lateral cilia are related to carrying food particles and generating water current respectively.

前纤毛和侧纤毛分别与食物的运送和呼吸水流的产生有关。

In the present study, we demonstrated that the mouse embryonic stem cells were differentiated into ciliated epithelial cells, with characteristics of normal ciliated cells.

通过我们的研究，实现了由小鼠胚胎干细胞向纤毛上皮细胞的分化，并且分化细胞具有正常纤毛细胞的特性。

The system used in this study more closely mimics the normal deelopment of ciliated cells; thus, an added adantage of the system is as a tool for studying the differentiation mechanism of normal ciliated epithelial cells.

而我们的诱导体系则更接近于纤毛细胞的正常发育条件，因此还可作为研究正常纤毛细胞分化机制的有力工具。

Coli. Expression of the major pilin of the recombinant kpa, kpb or kpe fimbriae could be detected by SDS-PAGE analysis.

为了阐明这些新纤毛的功能，我们以聚合酶连锁反应由NTUH-K2044染色体中选殖这些纤毛基因组到无纤毛的大肠杆菌BL21(DE3)。

The N terminal of XpsG, H, I , J and K protein are homologous with the pilin of typeⅣ secretion system, those are predicted to be assembled into a pilus-like structure between the cytoplasmic and outer membrane. The pseudopilus is presumed to push exproteins into the outer membrane.

其中XpsG、H、I、J和K蛋白NH2-端与第四型纤毛生成系统中的纤毛组成蛋白有同源性，推测可在内外膜之间组装成类纤毛构造，并推动分泌蛋白进入外膜通道。

Healthy rabbits were inoculated each with vaccines of the recombinant Pilin and the recombinant fused Pilinn-IL2 protein at 250ug per dose to potentiate the immunogenicity. The D. nodosus Pilin vaccine and the killed D. nodosus whole cell vaccine were also inoculated into rabbits as controls in order to compare with the above two recombinant vaccines.

用纤毛蛋白基因工程疫苗、Pilin-IL-2融合基因工程疫苗分别免疫健康家兔，初步进行了纤毛蛋白疫苗和Pilin-IL-2融合基因工程疫苗的免疫原性试验，并同时用节瘤拟杆菌菌体灭活疫苗及菌体纤毛蛋白疫苗免疫家兔，进行了免疫原性比较试验。

Methods Choose 38 cases of patients with RRTI as study group,respiratory ciliated cells were collected by bronchial fiberscope in acute stage and convalescence stage respectively,observe the change of cilia structure by electron microscopy and compare the incidence of cilia cylindrical epithelium structure abnormality.

选择符合儿童RRTI诊断标准的患儿38例作为研究对象，分别于急性期及恢复期在纤维支气管镜下夹取支气管黏膜组织，电镜下观察纤毛上皮结构的特点并比较纤毛异常的发病率，探讨RRTI患儿治疗后纤毛的恢复情况。
