2The distribution of HIF-1 a and COX-2 was unequal;.(3)These findings indicate that HIF-1a and COX-2 may be two important factors in pulpal lesions and there is a significantly hypoxia condiction in inflamed pulp .(4)The increase of HIF-1 a is a possible mechanism for hypoxia preconditioning .(5)Our results suggested that pulpal fibroblasts as well as macrophages might be involved in the pathogenesis of irreversible pulpitis.

和COX一2的表达均有不同程度的变化，在牙髓炎病程中可能发挥着重要的生理和病理作用，③在牙髓炎进程中和牙髓自身修复过程中存在着缺氧环境和缺氧耐受机制，④牙髓成纤维细胞有可能与单核巨噬细胞一同参与牙髓炎的病理进程，且具有修复和免疫功能。

Objective To investigate the best method of culture conjunctival epithelial cells and fibroblasts in vitro , and further more to provide a foundation for investigating its biologic feature and reconstruction.

目的 探讨体外培养兔眼结膜上皮细胞和成纤维细胞的最佳方法，为进一步研究结膜的生物学特性和结膜重建提供基础。

Results 6 patients with PAP presented with ground-glass opacification of the bilateral lungs on HRCT. Typical chest HRCT scan showed "map-like" lesions in 3 cases and "cobble stone-like" lesions in 3 cases. Multifocal consolidative opacities in the lungs were seen on HRCT in 3 cases. Lung biopsies from 6 patients with PAP revealed a prominent positive periodic acid-Schiff intra-alveolar exudates. There were normal alveolar spetasis in 3 patients while interstitial thickening, fibroblast hyperplasia, interstitial fibrosis in the others.

结果 6例患者在不同层面可见磨玻璃影，其中2例可见小结节影；3例表现为两肺斑片状磨玻璃影与周围肺组织分界清楚，呈地图样改变；3例因磨玻璃影与小叶间隔增厚交织成铺路石样改变；3例可见肺泡实变融合成密度较高的斑片状阴影，1例在肺泡实变区可见&空气支气管征&。6例患者活检肺组织在光镜下显示肺泡腔内充满大量块状或颗粒状嗜伊红物质，PAS染色阳性，AB染色阴性，其中3例肺泡间隔正常，3例肺泡间隔增宽，可见慢性炎性细胞浸润、成纤维细胞增生和胶原沉积。

Results After used the SGS , the arrange of collagen tend to unifying , micrangiums are rich and in opening condition, the polymeride of pre-collagen accumulate in cytochylema in fibroblast, the total content of collagen is decreased, but the content of hPcⅢ is kept in a high level, the content of HA is increased gradually,which closes to the normal skin level.

结果 应用硅凝胶膜后，胶原排列趋于一致，微血管丰富而呈开放状态，成纤维细胞的前胶原聚合体蓄积在细胞浆内；胶原总的含量减少，但Ⅲ型前胶原含量维持在一个较高水平；透明质酸含量逐渐升高，接近正常皮肤水平。

However, the molecular mechanisms underlying premature aging up 8-MOP/UVA are as yet unknown. In our studies, dermis of the non-lesion back skin of vulgar psoriatic patients who had been treated by PUVA and the cultured foetus dermic fibroblasts were selected to be observed.

本课题以PUVA治疗寻常型银屑病患者背部非皮损区真皮及培养的胎儿真皮成纤维细胞为对象，采用HE染色、Verhoeff染色、电镜、酶组织化学、免疫组织化学、原位杂交、流式细胞计数仪、三引物PCR、PCR-SSCP技术及PCR产物直接测序等技术和方法，研究了8-MOP/UVA对皮肤光老化形成的影响及芳维A酸乙酯的拮抗作用。

This area is ringed by the inflammatory component with epithelioid cells, lymphocytes, and fibroblasts.

此区由炎症成分围成环状，这些成分包括上皮样细胞，淋巴细胞，成纤维细胞。

The corneal fibroblast of rabbit formed a monolayer and had a fibriform arragement after two weeks culture in culture flasks.

眼角膜成纤维细胞在培养瓶中培养 2周后可形成单层；2 4孔板培养 3d后细胞贴壁生长旺盛，10d形成单层。

These findings suggest that epithelial cells play an important role in promoting ALPase expression in pulp fibroblastic cells.

综上所述，上皮细胞在提高牙髓成纤维细胞ALPase表达方面起到重要的作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
