血管收缩的

Methods The constriction induced by norepinephine (NE, 10-8-10-4 mol/ L) and diastole induced by acetylcholine (Ach, 10-8 -10-4 mol/ L) in thoracic aortic ring with angiosteosis induced by vitamin D3 plus nicotine in rats were recorded by BL-Newcentrary multichannel physiologic recorder.

维生素D3(VitD3)和尼古丁诱导大鼠血管钙化模型，通过BL-Newcentrary型多导生理记录仪，观察钙化大鼠离体胸主动脉环对去甲肾上腺素(norepinephine，NE)(10-8～10-4mol/L)和乙酰胆碱(acetylcholine，ACh)(10-8～10-4mol/L)引起的收缩和舒张反应。

Coronary flow velocity was recorded by using Cardiometric FloMap Ⅱ by introducing the Dopplerflowire into the target arteries. The average peak veloity and coronary flow reserve were measured before anafter PTCA and after stent implantation.

在PT-CA前后和支架植入术后，采用Cardiometric FloMap Ⅱ血管腔内多普勒血流速度描记仪和多普勒导丝，测量狭窄近端和远端的平均峰值流速、舒张期与收缩期流速比、近远端血流速度之比、冠脉血流储备。

Arterial elastance and entricular end-systolic elastance were similarly increased in hypertensive controls and HFnlEF patients compared with healthy controls.

而高血压对照组和射血分数正常的心衰患者组血管弹性回缩率和收缩末期心室弹性回缩率都有所增加。

Abstract］ Objective To investigate the effect of eucommia ulmoide oliver on the contraction of rat thoracic aorta rings.

目的 探讨杜仲对大鼠离体胸主动脉血管环收缩活动的影响。

Objective Pulsed wave Doppler tissue imagingwas used to quantitively analyse left ventricular systolic function before and after revascularization.

目的 采用脉冲多普勒组织成像技术定量分析血管重建术前后左心室的收缩功能。

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。

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。

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。

Nose drops or inhalations containing drugs that contract Blood vessels help drain the sinuses .

鼻滴剂或吸入剂含有可收缩血管帮助鼻窦畅通的药物成分。

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。

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。
