查询词典 basement membrane

Results showed that the only intact basement membrane complex was found on the luminal surface of the ECM deried from the urinary bladder and that the basement membrane was an effectie barrier to penetration of the scaffold by the seeded cells.

结果表明，只有在膀胱来源的ECM支架内表面才发现了完整结构的基底膜复合物，而且这种基底膜结构是支架阻碍种植细胞渗透生长的有效屏障。

We conclude that the urinary bladder ECM but not the small intestine- or lier-deried ECM contains a surface with composition and morphology consistent with that of an intact basement membrane complex, that the basement membrane complex can surie processing, and that the basement membrane structure can modulate in itro cell growth patterns.

我们得到的结论是，膀胱来源的ECM含有一层组成和形貌都与完整基底膜复合物一致的表面结构，而小肠和肝来源的ECM没有这层结构；基底膜复合物结构能够在ECM整个加工过程中保证完整而且能调节体外细胞生长模式。文献摘要申领

Under electron microscopic observation, capillaries of SFO are fenestrated ones, the endothelium of them are short of the tight junction, their basement membrane are not intact, the gaps between the endothelium and basement membrane are widened, to which the gaps within the endothelium are opened, the end feet of astrocytes surrond the capillaries not completely, and on the luminal surface of the endothelium some small vesicles are adhere to it, all of which suggesting SFO short of blood brain barrier .

在电镜下观察，穹窿下器的毛细血管为窗性毛细血管，内皮缺乏紧密连接结构，基膜薄而不完整，内皮与基膜之间的间隙宽大，内皮裂隙可通向此间隙，毛细血管内皮腔面可见贴壁小泡，星形胶质细胞脚板未完整包围毛细血管，这些结构特点提示SFO的血脑屏障不完整。

Methods The thickness of retinal capillary basement membrane and glomerular basement membrane and their anionic sites were quantitatively analyzed by electron microscopy and immunohistochemical methods.Results RBM and GBM became gradually thickened with the development of diabetes. The thickened basement membrane was accompanied with decrease of anionic sites in number.Conclusion DR and DN share partly the pathological process, and there are also some incoordinate phenomena in the microvascular lesion.

我们采用普通电镜和免疫组化电镜等方法对糖尿病动物模型进行了系统观察，着重对比分析视网膜和肾小球微血管病变，试图寻找DR和DN的相关性，以期阐明其发生、发展的规律，为临床探索或延缓糖尿病患者并发DR或DN的手段提供理论依据。

Iron deposit can be found in epithelial cells, basement membrane and Bowman membrane of keratoconus.

圆锥角膜的上皮细胞、上皮基底膜及Bowman膜可见铁质沉积。

Results Non-specific antibody increased distinguishingly in each groups after drug treatment 30 days, but all tested indexes showed no anychange in 2mg/ group. Glomerular basement membrane became thick in 10mg/ group after drug treatment 90 days, but it showed normal when treatment time was shorten to 30 days. The thickness of glomerular basement membrane was very serious in in 50mg/ group and liquid containing protein was found increasing in glomerular and tubular. The thickness of glomerular basement membrane didn't ameliorate after stopping drug 30 days.

结果 给药后30天各给药组动物血清非特异性抗体明显升高。rhIL-1Ra 2mg/组其他检测指标均未见明显地改变。rhIL-1Ra 10mg/组给药后90天肾小球毛细血管基底膜明显增厚，但此剂量给药时间为30天时未见任何异常。rhIL-1Ra 50mg/组肾小球及肾小管中蛋白性液体量多，小球毛细血管基底膜增厚更为严重，且停药30天后基底膜增厚程度仍未见明显减轻或改善。

Electron microscopic findings were: 1. alveolar type I cells were degenerated、 broken-down and desquamated, endothelial cells were swelled, with inter cellular tight junction shortened, alveolar type II cells hyperplastic, basement membrane thinned and deformed; 2. alveolar macrophages and interstitial macrophages were hyperplastic; 3.mast cells were infiltrated and degranulated; 4.electron-dense deposits were present at alveolar wall; 5. myofibroblasts 、fibroblasts、 collagen and basement membrane like material were hyperplastic.

In the precessing of tumor invasion and metastasis, extracellular matrix and basement membrane are playing an important role of barrier.

在肿瘤的侵袭和转移过程中，细胞外基质(extracellular matrix，ECM)和基底膜(basement membrane，BM)起着重要的屏障作用。

Results The expression of endogenous LN was found in the basement membrane of epithelium, glands and blood vessels in uterine endometrium of both estrus and early pregnancy. And its was faint that LN present in basement membrane as the implantation occurs, but the LN immunostaining in the epithelial cells of endometrium was stronger. The exogenous LN has no obvious influence on blastocyst attachment and implantation. LN-antibody intra-uterine injection showed significant repressing effect on mouse blastocyst implantation.

结果 动情期及妊娠早期小鼠子宫内膜内源性LN在上皮和腺基膜及血管内皮基膜均有表达，并随着植入的发生基膜的LN表达减弱，而内膜上皮中LN免疫染色逐渐增强；外源性LN对小鼠胚泡粘附与植入子宫内膜不产生明显影响，层粘连蛋白抗体明显抑制小鼠胚泡着床。
