血流

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。

Objective To investigate whether functional abnormalities in coronary vasomotion are present in asymoptomatic patients with slight hypertension.

应用经胸超声心动图冠脉血流显像技术测量 2 3例无症状轻度高血压患者在静脉输注潘生丁溶液结合等长握力负荷状态下前降支冠脉血流的速度变化，并与 2 1例正常健康者对照。

Analysis of vertebroar terial blood flow has shown that in cases with pathological conditions the compl iance of the vertebral artery and peak systolic veolicity and capacity are signi ficantly decreased Conclusions:The Segmented K-space cin e phase-contrast MR is an important tool for non-invasive evaluation of vertebroarterial blood flow.

血流分析表明在病理情况下椎动脉的顺应性低于正常组，峰收缩期流速和平均流速明显降低，返流均百分比增加。结论：MR相位速度图对椎动脉的血流动力学研究具有重要意义，对椎动脉型颈椎病可提供可靠的诊断依据。

Results: Before and after treatment,the differences of hemodynamics and vertebrobasilar artery mean flow velocity were statistically significant.

结果：治疗组治疗前后血流动力学和椎基底动脉平均血流速度等指标的变化差异均有统计学意义（P.05或P.01）。

In io administration of anti-EGF antibody abrogates both the acceleration of the recoery of blood flow in the ischemia-induced limbs by M-CSF and the augmentation of the mobilization of EPCs induced by M-CSF.

而体内给予抗EGF抗体可消除M-CSF诱导的血流恢复加快和EPCs动员增加，提示M-CSF动员EPCs通过增加EGF的生成以促进缺血组织血流的快速恢复，同时提示EGF主要生成于髓系细胞。

The ultrasonogram characteristic of CHU was just like honeycomb anechoic opaca. There was no obvious blood signal in all the angiomas, but rich blood flow just like limb could be seen around the lesion.

特征性声像图表现为蜂窝状无回声暗区，CDFI其内未见明显血流信号显示，边缘可见丰富的树枝状血流。

Although methadone administration did not produce hemodynamicinstability in this study, the possible hemodynamic side effectsof histamine release should be considered when IV boluses ofmethadone are given.

尽管在此次试验中，美沙酮并没有造成血流动力学不稳，但是当静脉给予单次大剂量美沙酮时应该考虑到有可能因为组胺释放而产生血流动力学方面的副作用。

Patients in CO2 group were insufflated with CO2 at pericardial cavity via a new designed gas-diffuser during ECC, whereas 16 patients in control group were not.

所有病例均以经颅多普勒超声微气栓检测系统于两侧头颅体表检测大脑中动脉血流微栓子信号，在ECC期间分五个时段分别记录和计算单位时间内血流中微气栓数目，两组之间结果进行比较。

Shapes of perforating branches in malignant and benign masses were also analyz...

结论CDFI显示的血流分级和血流形态表现有助于胆囊良恶性占位病变的鉴别，是二维超声诊断的重要补充信息。

To summarize advance on biological signal acquisition and processing system and its application of TCM,on the basis of working principle and its application for example power Lab system,Chinese medical treatment on dystonia,electrophysiology,blood flow,blood pressure and he...

主要以PowerLab系统为例，在阐述生物信号采集处理系统工作原理及应用的基础上，从观察中药对肌张力变换、电生理及血流、血压及血流动力学等的影响等几个方面，综述了生物信号采集处理系统在中医药研究中的应用概况，并提出了应注意的问题。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
