RESULTS: TEM displayed normal morphology of EC, its conjunction, SMC and intimal elastic lamina in control group, while in SAH group, marked pathological changes were observed, including desquamation and dystrophy of ECs, disruption of tight junction, vacuolated cytoplasm, condensation of chromatin in ECs, corrugation of IEL, and distortion of SMC. In other groups, TEM showed slight ultrastructural changes in EC, SMC and IEL.

结果： 电镜下，对照组血管壁超微结构无变化；SAH组电镜下血管内皮层结构以及内皮层细胞结构发生严重变性改变；用药治疗和预防组电镜下各组之间血管超微结构的改变无明显差异，组织变性程度明显轻于SAH组。

Vascular endothelial growth factor is a specific mitogen of endothelial cells and plays an important role in vasculogenesis and angiogenesis.

血管内皮生长因子是内皮细胞的特异性致裂原，在血管发生和血管生成过程中占有重要地位。

As a biomarker of vascular endothelial cells proliferation,CD105 stimulates vasculogenesis and plays key role in tumor angiogenesis.

CD105是血管内皮细胞增殖的标志之一，同时直接参与血管生成，在肿瘤血管生成过程中发挥重要作用。

Vasculogenesis and angiogenesis are two types of neovascularization in the embryo development.

在胚胎发育过程中，血管系统的建立始于两种方式：血管发生和血管新生。

Decade, the concept of postnatal vasculogenesis has been revolutionized to includeangiogenesis by mature endothelial cells and vasculogenesis by endothelial progenitor cells.

在过去的十年，出生后血管生成的概念已经变革为包括成熟内皮细胞的血管新生和内皮祖胞的血管生成。

Present results also suggested that zebrafish as a quality model for study on vasculogenesis and angiogenesis during embryonic development and screening for angiogenic enhancer or inhibitors.

斑马鱼是研究胚胎发育早期微血管发生和血管发生的极佳动物模型，可用于促血管发生或抑制血管发生药物筛选。

When cultured in three-dimensional matrix, the cells were elongated and migrated into the gel, with a phenotype similar to that in the process of angiogenesis and vasculogenesis in vivo .

在二维平面培养中，原代心脏血管内皮细胞呈铺路石样排列；而在三维胶原培养模式中，内皮细胞呈长梭状形态，并迁入胶原培养介质中，和体内血管新生及血管生成过程中的内皮细胞活化表型相似。

As the temperature of rat aorta was raised, the vasoconstrictive force and vasoconstrictive speed increased, and the effects of norepinephrine on vasculature were raised. The results suggest that the constant X1 for vasoconstrictive force is a factor sensitive to temperature.

认为NE引起的血管收缩张力的大小，显然也处于温度的影响之下；随着温度的升高，血管收缩张力变大，收缩速率变快，NE对血管的作用效力增强；且张力因子X1是温度敏感因子。

In physiolgoical state,the action of traditional RAAS on blood pressure might be decreased with age in aged people,and the vasoactive peptides might contribute more to the cardiovascular action to keep blood pressure stable. Activity of vasoconstrictive peptides were incresaed and activity of vasodilative peptide was decreased.

老年人随着年龄的增长，在生理状态下传统的RAAS的作用减弱，更多的是血管活性肽(ANP，ET，CGRP)参与心血管活性的调节，老年EH患者缩血管肽ET的活性增高、舒血管肽CGRP活性减弱。

Aim: To study the effects of angiotensin receptor antaganist-valsartan on vascular hypertrophy、vasomotion function and aorta vascular smooth muscle cell EGF precursor mRNA expression in spontaneously hypertensive rats.

目的：本文探讨血管紧张素受体拮抗剂-缬沙坦对自发性高血压大鼠血管结构、功能以及主动脉血管平滑肌表皮生长因子前体 mRNA表达的影响。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
