血管收缩的

The strips of the rat arteries were mounted in an organ chamber filled with 37 ℃ PSS and the vascular tension was measured.

测定离体肠系膜血管床灌注压和离体尾动脉肌条血管张力，以其对去甲肾上腺素收缩反应的变化作为舒缩活动的指标。

Treatment group was treated with valsartan and control group was treated without drugs such as ACEI or ARBs. Pmax,Pd and LADd,LVDs,LVDd were measured and compared before treatment and 6 months' after treatment. Result: There was significant difference in Pd , Pmax and LADd between treatment group and control group .

治疗组给予缬沙坦治疗，对照组给予非血管紧张素转化酶抑制剂类及非血管紧张素受体拮抗剂类降压药治疗，观察药物治疗6个月前后心电图中的Pmax和Pd及超声心动图中的左房舒张末内径、左室收缩末内径、左室舒张末内径的变化。

In 66 anaesthetized rats, the effects of local injection of agmatine on femoral, renal, and mesenteric vascular beds were investigated respectively by constant flow perfusion method.

在66只麻醉大鼠，分别采用后肢、肾脏和肠系膜动脉在体恒流灌注法，观察了向灌流环路中直接注射胍丁胺(agmatine， AGM)的血管效应，以所引起的灌流压增减反映血管的收缩和舒张。

GA had no effect on SMA constriction induced by NE. The reactivity of SMA rings to myricetin was increased at 0, 0.5, 1 hour and 2 hours after shock, and it reached the peak at 2 hours, then it significantly decreased at 3 hours and 4 hours after shock.

结果 SMA血管环对NE的反应性表现为：休克0 h和0.5 h组明显高于正常对照组和其他休克时间点组，休克1 h和2 h组明显低于正常对照组和休克0 h和0.5 h组；18α-GA对NE诱导的SMA血管环收缩反应性无明显影响。

Methods There were to patients of diabetes and 35 patients of non-diabetes in this study. The diameter, inter median thickness, peak systolic velocity, end diastolic velocity, pulsatility index, and resistance index of bilateral common femoral artery, superficial femoral artery, profunda femoral artery, popliteal artery,and pedal artery,and whether there was arteriosclerotic plaque or occlusive diseases were examined with color Doppler ultrasonogh.

糖尿病组70例，非糖尿病组35例，分别应用彩色多普勒超声观察双侧股总动脉、股浅动脉、股深动脉、腘动脉、足背动脉的血管内径、内－中膜的厚度、收缩期最大峰值血流速度、舒张期末血流速度、搏动指数、阻力指数；观察血管内有无硬化斑块、有无完全性和不完全性动脉闭塞。

Results Following hemorrhagic shock, the systemic and local vascular responsiveness was significantly decreased significantly and it was time dependent. Shed blood reinfusion alone did not restore the decreased vascular reactivity.

结果失血性休克后全身（血压对 NE的升压反应）和局部（SMA对NE的收缩反应）血管反应性显著降低，且呈一定的程度和时间依赖性，即休克程度越重，时间越长，血管反应性降低越多。

After acetylating, the effect of the transformed PAF on platelet aggregation was compared with that induced by standard PAF for quantification.

目前发现PAF除引起血小板聚集外，还具有较为广泛的生物学作用，如增加血管通透性、促进白细胞趋化与激活、扩张血管、抑制心功能及收缩支气管等〔。

Methods The effects of three vasodilators on the potassium chloride, norepinephrine concentration-response curves and precontracted rabbit aorta were investigated.

以离体兔主动脉条观察该三种血管舒张药对氯化钾、去甲肾上腺素量效曲线及预收缩血管的影响。

These compounds inhibit an enzyme called angiotensin--converting enzyme, which is responsible for making the muscle cells in blood vessels contract, which drives blood pressure up.

这些化合物能抑制一种叫血管紧张肽—转化酶的酶，这种酶使血管肌细胞收缩，从而驱使血压上升。

Furthermore, allatostatins inhibit contraction of muscles in heart, dorsal vessel and oviducts.

AS能抑制前肠、中肠、后肠肌肉的收缩，导致昆虫厌食、生长延迟、死亡率上升等现象，此外，还能抑制心脏、背血管和输卵管等器官中肌肉的收缩。

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。
