引起血管收缩的

Stress causes constriction of blood vessels, limiting the space for blood to flow.

压力引起血管的收缩，限制血流空间。

"Ice on his forehead," is that the role of the skin by cold forehead, the nose can achieve vasoconstriction in order to stop bleeding, but its effects are not good, because bleeding from the nose position too far away, and local too does not give rise to the head cold, so the correct way is to direct ice in the "nasion" and "nose" above.

"冰敷额头"的作用是希望藉额头的皮肤遇冷时，能达到鼻部血管收缩以止血，但其效果并不好，因为距离出血的鼻孔部位太远，且局部过于冰冷会引起头部不适，所以正确的方法是可直接冰敷在"鼻根"及"鼻头"上面。

Both ACEI with or without sulfhydryl groups could prevent the H2O2 induced decrease in contraction responses to PE in intact aortic rings. The increase of NO and activation of HO-1 might be involved in the mechanism.

含有和不含筑基的ACEI均具有对抗H2O2引起的血管收缩功能下降的作用，其主要机制可能是通过引起NO产生增加和诱导HO-1而实现的。

As a result of high blood pressure can also lead to reflex vasoconstriction, which is why the treatment of angina pectoris should be used as well as blood pressure lowering drugs.

由于过高的血压也会引起反射性血管收缩，所以应使用既能治疗心绞痛，又能降血压的药物。

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。

When cellular Ca~(2+) concentration increased, Ca~(2+)与can combinewith calmodin create compound, the latter arose VSMC shrinking through phosphated, and can accelerate express of many cancer gene, such as c-fos、c-myc、c-myb, consequently bring the multiplication and plumped of VSMC.

当细胞内Ca~(2+)浓度升高后，Ca~(2+)与其细胞内受体钙调素(Calmodin，CaM)结合生成复合物，后者通过一系列磷酸化过程引起平滑肌细胞收缩，并可促进多种癌基因的表达，如c-fos、c-myc、c-myb等，从而引起血管平滑肌肌细胞的增殖和肥厚。

Topical application of AVP (except at the lowestconcentration used here) induced concentration-dependent vasoconstrictionof pial arterioles in anesthetized rabbits.

AVP 的局部应用（这里使用的最低浓度除外）可引起麻醉兔软膜小动脉浓度依赖性血管收缩。

This study aimed at the influence of temperature on the vasoconstrictive effect of norepinephrine on rings of rat aorta and at the cause of the change observed.

研究温度对去甲肾上腺素引起的动脉血管收缩张力变化的影响及原因。

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。

This contracting effect of NE on BA could be augmented by β-adrenoceptor antagonist propranolol (10〓mol/L)(there was no this augmenting effect in RA) and could be antagonised by α〓-adrenoceptor antagonist prazosin but couldn′t be antagonised by α〓-adrenoceptor antagonist yohimbin (10〓mol/L).

这说明AVP引起的收缩在BA对胞外钙的依赖性明显大于RA，提示与V〓受体耦联的胞内钙池在BA明显小于RA。因此，血管活动的个血管活动的个性现象绝不仅仅是受体分布的差异所致。

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。
