血管收缩的

Alcohol can dilate small blood vessels, which may lose their ability to constrict.

酒精会扩张细小的血管。这样就会使血管丧失收缩的能力。

To conserve blood that will be needed by muscles, skin vessels constrict while vessels of the muscles dilate

为了保存肌肉所需要的血液，皮肤血管收缩，而肌肉血管舒张。

Endothelial cells produce potent vasodilators and the most potent vasoconstrictor, endothelin.

内皮细胞产生强烈的血管扩张素和最强烈的血管收缩素――内皮素。

Ang II is a vasoconstrictor and growth-promoting substance, whereas bradykinin is a potent vasodilator and growth inhibitor.

Ang II 是一种使血管收缩和促进生长的物质，而BK 是使血管舒张和抑制生长的。

We also found that FHL2 is important in the regulation of vasomotor tone, or the contraction and relaxation of muscles in the blood vessel.

Hata说，我们已经发现FHL2是调节血管紧张性或收缩和舒张血管肌肉的重要蛋白。

GA antagonized SMA constriction induced by myricetin. The antagonizing effect on myricetin in shock 1, 2 and 3 hours groups was more obvious than that in the other groups. CONCLUSION :At the early stage after hemorrhagic shock, the endothelium-dependent and independent vascular contractile response show a compensatory increase.

SMA血管环对杨梅黄酮的反应主要表现为：休克0、0.5、1和2 h组明显高于正常对照组，于休克2 h达最高点；休克3 h和4 h组明显低于正常对照组，运用18α-GA阻断MEGJ后，各组血管环的收缩反应性较18α-GA作用前明显下降，其中以休克1、2和3 h组下降幅度明显大于其他组。

If the cause is loss of volume, intravenous fluids should be supplemented; if vasodilatation (f. ex. due to large doses of epidural analgesia or habitual anti-hypertensive medication), the treatment is not fluid but is the dose adjustment of the provoking factor or vasoconstricting agents as e.g., Ephedrine.

如果低血压由液体不足引起，应增加静脉补液量；如果血管扩张（例如，因为大剂量硬膜外麻醉或习惯性的抗高血压治疗），则不需液体治疗而是调整扩血管药物的剂量，或使用血管收缩剂，比如麻黄碱。

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。

Isolated rat pulmonary artery was perfused and the tension of the vessel was measured, the effect of isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate on the pulmonary artery precontracted by noradrenaline and concentration-response curves of 5-hydroxytryptamine(5-HT), endothelin-1(ET-1), U46619 and KCl was also observed.

制备大鼠肺动脉条，采用离体血管灌流方法，观察丹参素异丙酯对去甲肾上腺素预收缩动脉的舒张作用以及对多种血管收缩药量效曲线的影响。

Blowing fan near the fan when the side of sweat evaporate quickly, the skin surface temperature dropped, blood vessel contraction, while the other side of the skin surface temperature is still high, blood vessel expansion .

吹风扇风扇附近时，汗水迅速蒸发侧，皮肤表面温度下降，血血管收缩，而在皮肤表面温度的另一边仍然很高，血管扩张。

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。
