查询词典 endothelium

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 .

在整体和离体水平，选用大鼠高脂血症模型模拟动脉粥样硬化早期状况。用114只大鼠多指标着重研究n-3多不饱和脂肪酸在高脂血症状态下对内皮的保护作用，以探讨其预防动脉粥样硬化的机理。所采用指标包括：浸银法观察内皮细胞排列与形态；离体血管环观察内皮依赖性舒张；伊文氏蓝染料法观察内皮通透性。为探讨作用机理，进行了血脂和体重的动态监测、DPH(1，6-二苯基-1，3，5，乙三烯)标记红细胞膜的荧光光谱测定、红细胞膜流动性测定、血浆和红细胞膜脂质过氧化物测定。

Removed veins research demonstrate the main reason of transplanted vessel stenosis is the hyperplasic of endothelium. Which is a popular reaction when set vein into arteral circulation. It is caused by the transmission of smooth muscle cell to endothelium and proliferate and release extracellular matrix. These are two characteristics in pathology erg middle layer of sue proliferates and migrate to endothelium in early and excel of end thulium aggregate in cater stage. The colic and the motivation of end thulium hyper is the hyper of sac.

在mRNA水平，随着移植术后时间的推移，ECE的表达逐渐增高，手术后1W-2W达到高峰2W后表达逐渐下降，于8W左右趋于平衡，ET-1的表达与ECE的动态变化过程相似，亦于术手1W-2W达到高峰，在8W左右趋于平稳在蛋白质水平，以ET-1抗体免疫组织化学染色结果显示ET-1主要在血管内收细胞及平滑细胞胞浆中表达，尤其是中膜平滑肌细胞更为明显，呈棕黄色颗粒。

In normal postauricular skin, EGF was expressed in squamous epithelium in 14 samples (41%), fibroblasts in one sample (3%), and endothelium in none. No statistical difference in EGF expression was found between cholesteatoma and normal postauricular skin samples.

在中耳胆脂瘤组织细胞中，EGF阳性百分比在squamous epithelium、endothelium及fibroblast细胞分别为53%（21例）、5%（2例）及5%（2例）；而在耳廓后皮肤组织中，其阳性率分别为41%（14例）、0%（0例）及3%（1例）。

Effects of H_2O_2 on the tension of isolated aortic rings of rat As above methods,Our results indicated that (1) aortic rings with endothelium precontracted by NE to 10000μmol/L H_2O_2 induced a relaxation; aortic rings with endothelium to 100μmol/L H_2O_2 induced a significant contraction;H_2O_2 induced the same effects in aortic rings without endothelium, there is significant difference in presence and absence of endothelium.
