Angiostatin is an effective suppressing protein to angiogenesis or vasculogenesis by inhibiting proliferation, migration and tube formation in endothelial cells, so it is considered as a sufficient inhibitor of tumor metastasis.

血管生成抑制素是一种新血管生成抑制蛋白，它可以有效抑制内皮细胞的增殖、迁移和管状形态的产生，是肿瘤转移的有效抑制剂。

Ox-LDL can inhibit the proliferation of EPC and promote the apoptosis of the cells by down-regulation of bcl-2 expression, which may contribute to vasculogenesis and reparation of blood vessel endothelium.

氧化型低密度脂蛋白通过下调bcl-2的表达诱导内皮祖细胞凋亡、抑制内皮祖细胞增殖，这可能影响血管内皮的修复及新生血管的形成。

Thin-layer collagen gel, microscope slide chamber and aorta-strip model were also tested and proved to be good tools for vasculogenesis or angiogenesis studies.

本工作表明，改进的薄层胶原培养、玻片培养小室模型和动脉条模型是较好的研究血管生成和血管新生的工具。

Fourpatientswere diagnosedfree ofASO,and 55 patients exhibited discontinued sclerosis orblock of lower extremity arteries around whichwere plenty ofblood-supply peripheral arteries.Conclusion 64-slice CT angiography can display the featuresof lower extremity arteries clearly,such as vasiform,arterial stenosis degree,occlusion and calcified plaque.

64层螺旋CT血管成像检查可清楚地观察下肢动脉的血管形态及管壁的钙化斑块，了解下肢动脉狭窄程度及闭塞情况，对下肢动脉硬化性闭塞性病变的术前评价、诊断和筛选有较大的帮助。

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。

If the cause is loss of volume, intravenous fluids should be supplemented; if vasodilatation (f. ex. due to large doses of epidural analgesia or habitual anti-hypertensive medication), the treatment is not fluid but is the dose adjustment of the provoking factor or vasoconstricting agents as e.g., Ephedrine.

如果低血压由液体不足引起，应增加静脉补液量；如果血管扩张（例如，因为大剂量硬膜外麻醉或习惯性的抗高血压治疗），则不需液体治疗而是调整扩血管药物的剂量，或使用血管收缩剂，比如麻黄碱。

AngiotensionⅡand endothelin-1 are two important vasoactive peptide,having powerful vasoconstricting and hemodynamic function,except this,both have nonhemodynamic effects as growth factor to induce proliferation,hypertrophy,to stimulate synthesis of matrix proteins,furthermore,also to inhibit matrix degradation, even to mediate inflammation reaction.

血管紧张素Ⅱ(angiotensinⅡ，AngⅡ)和内皮素1(endothelin1，ET-1)是两个重要的血管活性激素，除了血流动力学作用外，还有非血流动力学作用，如促进细胞增生、肥大，刺激细胞外基质的合成并抑制其降解，介导炎症反应。

Vasoconstrictive action : constriction of the blood vessels, via action of a nerve.

血管收缩行动：建设中的血管，经由行动的神经中枢。

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。

Although it has been considered that this effect is due to an inhibition of the release of vasodilatory peptides, recent studies suggest that octreotide has a local vasoconstrictive effect.

虽然有认为这种效应是由于抑制了扩血管肽的释放，但最近的研究显示奥曲肽有局部缩血管效应。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
