血流

Tourniquets should only be used when optimal surgical conditions cannot be achieed without their use, as the resultant production of acidosis, reduced blood flow, and hypoxia creates sickling and further injury.

不使用止血带就不能获得最佳的手术状况时，方使用止血带。使用止血带可导致酸中毒、血流减少以及低氧导致细胞镰状并发生进一步的损伤。

Methods Twenty-two eyes of 22 patients with CSC were selected, and HRF, fundus fluorescein angiography and indocyanine green angiography were employed to detect the hemodynamics of sieve plate and retina in macula.

以22例（22只眼）中浆患者为研究对象，运用HRF、眼底荧光血管造影和眼底吲哚青绿血管造影检测视盘筛板和黄斑部视网膜的血流动力学指标。

The in vitro cell cultivated system was improved to form positive and backward flow fields in the loop so as to simulate bidirection blood flow or vortex flow at vessel embranchment, bifurcate, straitness or sinuosity.

对内皮细胞体外培养装置加以改进，在回路中形成既能正向流动，又能逆向流动的流场，旨模拟在血管分支、分叉、狭窄或弯曲处产生的双向血流或涡流。

The anterior descending branches of the left coronary artery was ligated with slipknot to block the blood flow and the myocardium was reperfused.

大白鼠随机分为7组，以活结结扎左冠状动脉的前降支，分别造成阻断冠脉血流和再灌注。

A great Hunter of Snarks is often renowned * From the beast he is never to flee * But still that is how he wound up in the ground-* For the Snark was a Boojum, you see

伟大的猎蛇鲨者总是以不让任何一只猎物逃脱而闻名不过这同样是令他倒地血流不止的原因因为那蛇鲨其实是一头"Boojum"。

Methods 100 patients with CSA and 100 people in the control group were examined by TCD,the change of blood flow of cerebrovascular (such as the velocity of blood flow, the form of spectrum, the souffle of blood flow) was analyzed.

应用TCD对100例CSA患者和100例对照组进行脑血流动力学进行检测，再对TCD检测正常的CSA患者和对照组进行TCD转颈试验，并将检测结果进行分析。

A new explanation of "false positive" on SPECT CBF imaging was discussed in this paper.

据此对脑血流灌注显像的"假阳性"问题提出了新的认识

The aim of our study is to find out the guidelines of applying SPECT and MR perfusion examinations.

我们经由实际测量SPECT及MRI的局部脑血流参数，其结果都具有不错的相关性。

The results of SPECT demonstrate the existence of regional hypo-perfusion of brain blood of patients with type 2 diabetes mellitus.

结论中年NIDDM患者确实存在记忆力的下降，局部脑血流的低灌注可能是原因之一。

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.

本研究采用大鼠深低温颈总动脉阻断模型，应用流式细胞仪、电镜、原位缺口末端标记法、免疫组化法和RT-PCR技术分别检测深低温脑缺血对皮层神经细胞调亡的影响方法：第一部分深低温停循环脑保护大鼠模型的建立：SD大鼠20只，麻醉后气管插管辅助呼吸，用冰块将大鼠的体温降至(21±1)℃，阻断双侧颈总动脉，记录体温、心率、血压、血氧饱和度和血气分析，60分钟后恢复颈总动脉血流，用Longa等的5级评分标准评定4小时和24小时后大鼠神经系统损伤情况。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
