血管作用的

Objective To explore the role of angiotensin Ⅱ and NADPH oxidase in vascular aging and its action mechanism.

目的探讨血管紧张素Ⅱ和NADPH氧化酶在血管衰老中的地位及作用机理。

Results The CaCl2 hollow stent could not only support the cannel of vascular, but also generate two membrane in the two side of anastomosis site. Thus the thickness of sealant was increased. It was effective to prevent leaking of cyanoacrylate glue and its toxicity.

结果：CaCl2中空支架不仅在血管吻合中支持血管，而且可以双面成膜，增加密封厚度，加强密封效果，能够有效阻隔医用胶对吻合口和管壁的毒性作用。

Many study indicated that VEGF is the most important and direct factor to stimulate vessel growth, and play an important role in neovascularization.

许多研究认为，血管内皮生长因子是目前发现的最重要、最直接的刺激血管生长因子，在新生血管的形成中起重要的作用。

Then made blood flow slowly and coagulate untile thrombosis, epithelial cell of vessel wall edema,aseprtic inflammation and necrosis,made the hemorrhoid's vessels atrophy,emphraxis,decrease,diminuting the volume of the vessels,relieving the pressure,at last adherence and fibrosis to gain the ends of hemostasia.

同时血管壁上皮细胞水肿，产生无菌性炎症、坏死。两种作用使痔血管萎缩、闭塞，痔组织发生粘连及纤维化而达到治疗的目的。

Stilbene glucoside protects HUVECs against hypoxia-reoxygenation injury, which has superior therapeutical effect to that of prevention.

二苯乙烯苷对血管内皮细胞缺氧复氧损伤具有明显的保护作用，而且其治疗作用优于预防作用。

It has recently been discovered that vascular remodeling also plays an important role in luminal loss after PTCA.

近年发现血管几何构型改变，即血管重塑对PTCA术后管腔丢失亦具有重要的作用。

VEGF seldom mediates angiogenesis in normal physiological condition, but it play an inerrant role in the pathological neogenesis of tumor vessel, which has expression of different extent in many tumors.

在正常人生理情况下VEGF介导血管新生不常见，在病理性肿瘤血管新生中起着重要的作用，在多种肿瘤中存在不同程度表达。

Objective To investigate the effects of several vasoactive peptides on the development of restenosis.

目的 研究血管活性肽在血管再狭窄形成中的作用。

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。

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。
