In Dex-pretreated group, no changes in CoBF was found after the administration of salicylate sodium.

水杨酸钠可减少耳蜗血流量，地塞米松可减轻水杨酸盐对耳蜗血流量的影响，内耳花生四烯酸代谢异常可能介导了水杨酸盐耳毒性的发生。

Remember, vasoconstriction means decreased blood flow and NO increases blood flow.

记住， 血管紧缩就是血流量减少，而一氧化氮能增加血流量

When the organ perfusion pressure changes, the arteriole resistance also change to keep the organ blood flow at a constant level, which is called the autoregulation of the blood flow.

当器官灌注压发生变化时，该器官的微动脉阻力也发生改变，使器官的血流量保持相对恒定的现象称为血流量的自身调节。

The levels of TGF-β1 in the alveolar lavement liquid and the sera in different time since irradiation were measured with ELISA.

结果照射后左肺血流量占全肺血流量百分率不断下降，肺泡灌洗液和血清中TGF-β1水平逐渐升高，以3～6个月最显著。

In men, it was found that stress was associated with increased CBF in the right prefrontal cortex and CBF reduction in the left orbitofrontal cortex.

在男性，结果发现，应力与增加脑血流量在右额叶及脑血流量减少，左眶皮层。

Dilates coronary arteries, improves blood flow to heart muscles, lower oxygen consumption of heart muscles.

有扩张冠状动脉﹐增加冠状动脉血流量及，心肌血流量﹐降低心肌耗氧量的作用

Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.

结果 生理盐水组，2mg／kg组，10mg／kg组PO_2值依次提高(p＜0.01)，脑皮质血流量依次提高(p＜0.01)；脑血流速度依次减低；脑梗死体积依次减少(p＜0.01)；同时在测定的时间段里PO_2和脑组织血流量值与时间成正相关(p＜0.01)；脑梗死体积和脑组织血流速度值与时间成正相关(p＜0.01)。E一选择素在脑缺血再灌注损伤中表达的实验研究中文摘要结论E一选择素能增加脑缺血再灌注损伤的脑组织氧饱和度，脑血流量，减低脑血流速度；减少脑损伤体积；从而保护了脑缺血再灌注损伤的脑组织。

MethodsThe external carotid artery of rat was ligated to observe the effect of PAMD on cerebral blood flow、cerebral vascular resistance、blood pressure and heart rate.

方法采用结扎颈外动脉的方法，观察PAMD对大鼠脑血流量、脑血管阻力、血压、心率等的影响。结果PAMD可增加脑血流量，降低脑血管阻力，对心脏功能无明显影响。

While after longer PDT, the endothelial ceils of capillary net were phototoxic necrosis, walls of capillary net were destroyed and the microvasculature was decreased dramatically.

微血管损伤明显，血流明显减慢，血流量为对照组的94.3％（P〉0.05）；光动力作用后第1天和第3天，微血管损伤加重，血流基本停滞，血流量分别为对照组的19.3％和21.6％（P〈0.05）。

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。
