查询词典 vasoconstrictive

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。

ET is a peptide with vasoconstrictive and vasodilator effect produced by endothelial cells,and NO as a powerful ...

实验证实ET和NO与肝硬化的发生密切相关。

There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.

人及哺乳动物体内有四种结构及药理学性质略有差异的异物体，分别为ET-1、ET-2、ET-3、ET-β，而在人主要是ET-1，在生理条件下，ET-1在血浆中含量较低，约为5ng〓，故ET-1不是一个循环激素，而是局部合成释放，局部起作用的活性物质，半衰期约1小时，ET-1是目前已知的最强的血管收缩剂，对静脉的作用比动脉强，在血管床，ET受体有A、B两型，A型主要分布在平滑肌细胞，B型主要分布在内皮细胞，它可以通过旁分泌途径刺激内膜增生，具有有丝分裂原效应，可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩，使静止期SMC进入增殖期，还可以通过信号传导途径，与bFGF、GTF-β、PDGF等生长因子协同作用，起共有丝分裂原作用。

Endothelin is a vasoconstrictive peptide produced by vascular endothelial cells, which consists of 21 amino acid residues.

内皮素是由内皮细胞产生的，含有21个氨基酸残基的血管收缩肽。

Vasoconstrictive action : constriction of the blood vessels, via action of a nerve.

血管收缩行动：建设中的血管，经由行动的神经中枢。

This study aimed at the influence of temperature on the vasoconstrictive effect of norepinephrine on rings of rat aorta and at the cause of the change observed.

研究温度对去甲肾上腺素引起的动脉血管收缩张力变化的影响及原因。

In forearm resistance arteries,ADM can abolish the vasoconstrictive effects of high dose norepinephrine or endothelin.

在前臂阻力血管低浓度的ADM可以逆转高浓度的NE或内皮素的血管收缩作用。

Although it has been considered that this effect is due to an inhibition of the release of vasodilatory peptides, recent studies suggest that octreotide has a local vasoconstrictive effect.

虽然有认为这种效应是由于抑制了扩血管肽的释放，但最近的研究显示奥曲肽有局部缩血管效应。

Endothelin-1 (ET-1), a peptide of 21 amino acid residues, is the most potent vasoconstrictive substance known.

概述 内皮素是一种由21个氨基酸组成的活性多肽，为目前已知缩血管活性最强的物质。

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。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
