血管收缩的

Methods: Fresh saphena rings were sudied in organ chamber after incubating with Krebs-Henseleit bicarbonate solutions, FWM, KH with 0.1mmol/L NCR, FWM with 0.1mmol/L NCR at 37℃ for 1 hour. Precontraction induced by prostaglandin F2 (U4661930nmol/L) and endothelium-dependent relaxation induced by calcium ionophore A23187 l0^(-10~l0^(-6) mol/L were measured in the presence of indomethacin (7μmol/L) and LNNA (300μmol/L). Result: No significant changes were found in the 4 groups under the light microscope.

采用器官槽法研究在37℃有氧条件下用重碳酸盐缓冲液、含0.1mmol/L NCR的KH液、FWM液、含0.1mmol/L NCR的FWM液中浸泡血管环1h后，再用7μmol/L吲哚美辛和300 μmol/L N-硝基－L-精氨酸作用后，检测30 nmol/L U46619及不同浓度A23187引发的血管收缩舒张反应。

Constricted, narrowed, or compressed, as a segment of a blood vessel.

收缩的收缩的、变窄的或压缩的，如血管的一段的

Abnormal vasoconstriction of digital arteries and cutaneous arterioles due to a local defect in normal vascular responses is thought to underlie the disorder .

本病的基础是因正常血管反应的局部缺陷而导致的指动脉和皮肤小动脉的异常血管收缩。

Results: The total saponins of Achyranthes Bidentata Blume not only had significantly inhibitive effects on NE-induced vasoconstriction, but also had direct relaxation effect on vascular smooth muscle.

结果：怀牛膝总皂苷不仅对NE引起的血管收缩有显著的抑制作用，而且还有直接舒张血管平滑肌的作用。

Also, take steps to keep your circulation healthy: Avoid cigarettes and caffeine, both of which narrow blood vessels; stay away from vasoconstricting meds such as decongestants; and hit the gym regularly.

还有，采取办法保持你的血液健康循环：避免吸烟和咖啡因，两者都会使血管变的狭窄；远离收缩血管的药物，例如解充血药物；并定期锻炼。

In forearm resistance arteries,ADM can abolish the vasoconstrictive effects of high dose norepinephrine or endothelin.

在前臂阻力血管低浓度的ADM可以逆转高浓度的NE或内皮素的血管收缩作用。

Excessive neural input does not mediate diminished vasoconstrictive responses in the ACL transected knee; inflammatory mediators may play a role in the deficient vascular responsiveness of the ACL transected knee.

过量的神经输入没有能够调节前交叉韧带切除了的膝关节的血管收缩应答反应；炎症调节因子可能在前交叉韧带切除的膝关节血管应答不良中期重要作用。

SI can inhibit vasomotion in vaso-dilation status, but its mechanism is not mediated by endogenous NO.

血管运动得以恢复；在SI的有效作用时间内应用L—NMMA则不能使处于舒张状态的血管收缩。

Lung Ang Ⅱ correlated positively with MIP-2 in BALF in all study rats. These results indicate that local angiotensin system is involved in the pathogenesis of VILI and suggest that blockade of Ang Ⅱ might have potential therapeutic implications in alleviating VILI.

这些结果表示局部血管紧缩素系统与机械通气导致肺伤害的病理生理机转有关，并且建议阻断血管收缩素可能有治疗机械通气导致肺伤害的潜在功效。

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。
