收缩血管的

Endothelin-1 (ET-1) is a potent vasoconstrictive and mitogenitic peptide generated by all types of cardiovascular cells. It plays an important role in many physiologic and pathophysiological processes such as heart development, heart failure, cardiac hypertrophy, arrhythmia and so on.

内皮素-1(endothelin-1 ， ET-1)是目前已知最强烈的血管收缩物质之一，主要分布于心血管系统，参与了心脏发育、心肌肥厚和心律失常等心脏生理和病理生理过程。

Body temperature is regulated by blood flow through the skin - vessels dilating and constricting with changing external conditions.

血液流过皮肤来调节体温-血管根据外部条件的变化扩张和收缩。

Therefore general rutin-Cd can cause decrease of blood pressure and cause relaxation of aortic muscle precontracted by NA.

芦丁金属配合物具有降低血压和抑制NA引起的血管收缩效应。

Result: Isopropyl 3-(3,4-dihydroxyphenyl)-2- hydroxypropanoate exerted relaxation effect on the endothelium-intact artery precontracted by NE in a concentration-dependent manner, which was inhibited with denuded endothelium. The right-shift of the concentration-response curves of 5-HT, ET-1, U46619 and KCl.

结果：丹参素异丙酯可浓度依赖性舒张NE预收缩的完整内皮血管，去内皮后该作用明显降低；对5-羟色胺(5-HT)、内皮素(ET-1)，U46619和KCl量效曲线均表现浓度依赖性抑制。

AIM: The aim of this study is to investigate the possible role of potassium channel in hypoxic pulmonary.

目的：以人离体肺动脉环缺氧张力变化为对象研究钾通道在缺氧性肺血管收缩发生中的作用。

And it still can increase coronary artery blood flow and reduce the oxygen consumption of cardiac muscle,thus making a cardiotonic effect and preventing Angina pectoris.

强心、降血脂、降血压：临床研究证实，山楂能显著降低血清胆固醇及甘油三脂，有效防止动脉硬化；山楂还能通过增强心肌收缩能力，增加心血输出量，扩张冠状动脉血管，增加冠脉血流量，降低心肌耗氧量等起到强心和预防心绞痛的作用。

Histamine causes vasoconstriction and increased permeability of small venules.

组织胺能引起血管收缩，并增强小静脉的透性。

Many also contain decongestants, which constrict the blood vessels in the nose and relieve congestion.

03/9/中许多药物都含有解充血成分，可以收缩鼻子里的血管，减缓鼻塞症状。

For example, cold weather makes the body's blood vessels, especially vulnerable to contraction and coronary artery spasm, easy insufficiency caused by the body and may lead to embolism.

比如气候寒冷使得人体的血管尤其是冠状动脉容易出现收缩和痉挛，易引起体内供血不足，并可能导致栓塞。

This leads to subtle changes in the autonomic nervous system, which controls the contraction and relaxation of these vessels.

这导致控制这些血管收缩和舒张的自主神经系统发生微妙变化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
