收缩血管的

Studies have shown that nicotine in cigarettes can be the nerve center of exciting vasomotor and increased secretion of adrenaline, causing contraction of small arteries.

研究表明，烟中的尼古丁可以兴奋血管运动神经中枢，并使肾上腺素分泌增加，引起小动脉收缩。

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。

However, in our functional experiment, LEM and NIC show relaxation effect in the presence of 40 or 60mM 〓. Thus it is necessary to define this criteria in exact terms, we recommended that potassium concentration higher than 80mM be used when employing the above criterium.

在功能实验中本研究结果提示，某些钾通道开放剂可舒张某一范围高钾浓度所致的血管收缩，因此，有必要对此标准进行量化，我们建议高钾浓度宜选用80mM〓以上较为合适。

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。

We investigated the effects of specificPDE-3 inhibitors (olprinone, milrinone, and amrinone) on contractedhuman gastroepiploic arteries ( n = 70), internal mammary arteries( n = 72), and radial arteries ( n = 70) harvested from a totalof 134 patients, all of whom were undergoing coronary arterybypass surgery.

我们在总共134例行冠脉搭桥手术患者身上采集了人胃网膜动脉（ n = 70）、乳内动脉（ n = 72）和挠动脉（ n = 70），并探讨了特异性 PDE －3抑制剂（奥普力农、米力农和氨力农）对这些血管收缩的影响。

When because become,spirit is in excited condition, blood pressure can lift namely, the heartbeat is accelerated, cardiac muscle oxygen demand increases, cause skull at the same time inside vasomotor, occurrence photophobia, risk golden light at the moment or scintilla, at the moment nigrescent, brief blindness, these are the foreboding of migraine.

因 为当精神处于亢奋状态时，血压即会升高，心跳加快，心肌耗氧量增加，同时引起颅内血管收缩，出现畏光、眼前冒金光或火花、眼前发黑、短暂失明等，这些都是偏头痛的先兆。

Reduction in blood flow to the nondependent lung can be caused by an enhancement of hypoxic pulmonary vasoconstriction , which is the main mechanism of decreasing transpulmonary shunt during OLV.

缺氧性肺血管收缩是减少OLV期间肺内分流的主要机制，增强HPV可减少OLV期间肺内分流。

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。

Urotensin II is a potent vasoconstrictive peptide and involves in hypertension and atherosclerosis.

加压素是一种血管收缩促进因子，可能参与高血压和冠状动脉硬化症的形成。

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。
