血管活性的

The Pathological changes of immune vasculitis were analyzed by hematoxylin and eosin staining, elastic fibers staining and electron microscopy.

目的 分析丹参酮ⅡA对免疫性血管炎、血小板及凝血活性的影响，探讨其抗血小板、抗凝及降低免疫性血管炎炎症反应的机理。

The authors conclude that during the period of CRF, the immunoreactions which mainly involve bio-active substances such as NPY, NT and5-hydroxytryptamine released by the platelet to interfer the vasoconstrictive effect are the main pathologic factors to induce renal hypertensin and renal vasospasm.

在CRF病理过程中，由血小板释放的NPY和NT与5-羟色胺等生物活性物质共同参与了以缩血管效应为主的免疫反应，是造成肾性高血压和肾血管痉挛的重要病理因素。

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。

A novel potent vasoconstrictor peptide produced by vascular endothelin cells〔J〕.

血管活性肽在大鼠血管再狭窄形成中的作用〔J〕。

Changes in blood flow are secondary to a relaxation of small arteries and arterioles, whilst changes in microvascular permeability, leading to inflammatory edema formation and cell accumulation, are mediated via changes that occur at the postcapillary venule level.

血管活性肽分子及其相关肽段可以内分泌的方式发挥循环激素的作用，还可以旁、自分泌的方式，通过其靶细胞表面的G蛋白偶联受体，在血管局部发挥其调节血管舒缩、细胞增殖迁移和分泌等复杂的生物学作用。

In addition, by activating transcription of the vascular endothelial growth factor gene, HIF-1α is considered to be a central initiator of angiogenic activity in tumors.

另外，HIF-1能激活血管内皮生长因子基因的转录活性，因而HIF-1被认为是肿瘤血管生成的重要起始因子。

It is suggested that these nerves may participate in the relaxation and constriction of the nonvascular smooth muscles. Perivascular nerve fibers in the genital organs may play an im-ortant role in the regulation of the uterine vascular tone.

分析雌性大鼠生殖器官内一氧化氮合酶Ⅰ免疫反应阳性神经纤维的分布，提示一氧化氮可能与血管活性或非血管平滑肌运动调节有关。

AngiotensionⅡand endothelin-1 are two important vasoactive peptide,having powerful vasoconstricting and hemodynamic function,except this,both have nonhemodynamic effects as growth factor to induce proliferation,hypertrophy,to stimulate synthesis of matrix proteins,furthermore,also to inhibit matrix degradation, even to mediate inflammation reaction.

血管紧张素Ⅱ(angiotensinⅡ，AngⅡ)和内皮素1(endothelin1，ET-1)是两个重要的血管活性激素，除了血流动力学作用外，还有非血流动力学作用，如促进细胞增生、肥大，刺激细胞外基质的合成并抑制其降解，介导炎症反应。

L-1 (10-7mol . L-1) noradrenaline induced contraction of rat aortic strip was taken as criterion. Compound I5 was shown to be a potent potassium channel activator. Compound II8 exhibited calcium antagonistic activity and showed potent vasodilating activity.

引起的大鼠主动脉条收缩有较好的抑制作用，其中化合物 I5的钾离子开放活性与尼可地尔相当，化合物 II8显示有钙离子通道拮抗活性，并有较强的扩血管活性。

Vascular endothelial growth factoris a new kind of blood vessel active factors was finded in recent years. It not only plays a very important role in the process of micrangium proliferation but also contributs to the stabilizing, maturating and refraining from apoptosis of nascent micrangium, it participates the vascular endothelial cell through specific binding with corresponding receptor.

血管内皮生长因子(vascular endothelial growth factor， VEGF)是近年来新发现的血管活性因子，通过与相应受体结合特异性的作用于血管内皮细胞，不仅在毛细血管增生中起着十分重要的作用，而且对于稳定新生的毛细血管，使之成熟，避免凋亡具有重要意义。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
