Therapeutic effect of sodium nitroprusside and dopamine is effective and safe in patients with grave chronic congestive heart failure.

使用血管扩张剂硝普钠，联合多巴胺治疗重症充血性心力衰竭有较好的协同作用，可有效地减轻心脏负荷，改善心脏收缩功能，而且患者的耐受性好，较为安全。

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。

Previous studies showed that before the pial artery large dilation which were widely observed in CSD, there is also a small constriction occurring in pial arteres.

已有研究表明，在普遍被观察到的CSD过程中软脑膜动脉血管大幅度舒张之前，还存在一个较小幅度的软脑膜动脉扩张和收缩。

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。

Endothelin is a vasoconstrictive peptide produced by vascular endothelial cells, which consists of 21 amino acid residues.

内皮素是由内皮细胞产生的，含有21个氨基酸残基的血管收缩肽。

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。

低浓度的ADM与NE或内皮素联合输注，即可完全逆转后两者的血管收缩作用。

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.
