舒张

The signal will not dephase, so arteries will be bright on diastolic scans.

在舒张期时，动脉内的血流因为流速相对缓慢而不会产生失相位，动脉呈高信号。

Results The blood flow velocity of ophthalmic artery and central retinal artery of the patients during systolicand dialytic ED...

结果糖尿病和慢性单纯性青光眼患者眼部动脉的收缩期血流速度和舒张期血流速度显著低于正常人（P值分别＜0.05及＜0.01）。

Especially the formation of reversal gradient of blood pressure before the dicrotic notch.

特别是逆向血压梯度的形成，认为动脉血流的惯性及左心室的舒张是重搏波切迹前短时期内近心端血压低于远心端血压的主要原因，在动脉中存在着惯性动能与压力势能之间的相互转化。

Arterial compliance was calculated as the integrated area starting at the well-defined nadir of the incisura of the dicrotic notch to the end of diastole of the radial artery pulse wave .

计算动脉顺应性的综合领域开始，明确界定的低潮的切迹的搏切迹的结尾舒张的桡动脉脉搏波。

It is an important medium which can dilatate blood vessel, participate in inflammatory reaction , infective immunoregulation activity and nerve conduction.

目的 一氧化氮是近年发现的一个高活性气体信号分子，除舒张血管外还是参与炎症反应、感染性免疫调控活动与神经传导的重要介质。

Fluvastatine may reduce plasma ET-1 level, raise plasma NO level, so it may improve endothelium-dependent dilative function.

氟伐他汀能够降低ET-1水平，升高NO水平，改善VA患者内皮依赖性舒张功能，从而缓解临床症状，改善预后。

Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.

结果 超声声像图显示3例胎儿在丘脑后下方、小脑上方有一无回声囊性结构，彩色多普勒超声提示无回声区内为高速低阻血流信号，与颅底动脉环间可见多条血管分支相通；脑室系统均未见扩大；胎儿心胸比增大，其中2例伴有上腔静脉内径增宽、三尖瓣反流；2例伴有胸腹水，1例全身皮肤水肿伴羊水过多，1例脐动脉舒张期血流反向。

In this context, we have reported recently that the volume of myocardial tissue occupied by perimysial and endomysial collagen was lower in hypertensive patients with HF and depressed ejection fraction, than in hypertensive patients with HF and preserved ejection fraction and normotensive subjects.56 Of interest, the interstitial and perivascular accumulation of collagen fibres was abnormally high in the two groups of patients.

在这种情况下，我们已经说了占用体积perimysial心肌组织人肌内膜胶原水平低的高血压患者用高频和沮丧的射血分数在高血压患者的心力衰竭和保存被罚出场分数与正常血压subjects.56舒张压的利息、间质和血管堆积过高的胶原纤维是在两组病人。

The function of adenosine is the most important. H+,CO2, ethylidene lactic acid 、BK、PGE also can dilate coronary.

心肌局部代谢产物是导致冠脉扩张的主要因素，其中腺苷作用最为重要。H+、CO2、乳酸、BK、PGE等亦可舒张冠脉。

The hypercholesterolemic rats were selected to imitate early stage of human atherosclerosis The effects and mechanism of n-3 PUFA on endothelium were investigated with the following parameters: the morphological appearance and arrangement of endothelium stained by Ag, in vitro endothelium-dependentrelaxation of aortic ring, endothelial permeability test using Even′s Blue, blood lipid and body weight in one-week intervals, excitative and emissive spectrum of RBC membrane labeled by DPH (1, 6-Diphenyl-1, 3, 5-hexatriene), fluidity of RBC membrane, plasma and RBC membrane LPO

在整体和离体水平，选用大鼠高脂血症模型模拟动脉粥样硬化早期状况。用114只大鼠多指标着重研究n-3多不饱和脂肪酸在高脂血症状态下对内皮的保护作用，以探讨其预防动脉粥样硬化的机理。所采用指标包括：浸银法观察内皮细胞排列与形态；离体血管环观察内皮依赖性舒张；伊文氏蓝染料法观察内皮通透性。为探讨作用机理，进行了血脂和体重的动态监测、DPH(1，6-二苯基-1，3，5，乙三烯)标记红细胞膜的荧光光谱测定、红细胞膜流动性测定、血浆和红细胞膜脂质过氧化物测定。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
