查询词典 carotid

This study suggests that it is not appropriate to only use the Casson equation to simulate the whole flow field of the carotid bifurcation, and on the other hand, Newtonian fluid is a good approximation to blood for flow simulations in the carotid artery bifurcation.

这表明，仅采用Casson模型模拟整个颈动脉流场是不合适的，而牛顿流体则是描述血液在颈动脉分岔血管中流动的一个很好的近似。

However, the Casson equation agrees well only when the shear rate is less than 10 s?1. The flow field of the carotid bifurcation usually covers a wide range of shear rate. We therefore believe that it may not be sufficient to describe the property of blood only using the Casson equation in the whole flow field of the carotid bifurcation.

然而Casson模型只有在低切变率条件下才与血液吻合的较好，而在颈动脉分岔血管中切变率值的分布范围却很广，因此，我们有理由认为，在整个颈动脉分岔血管流场中均采用Casson模型来模拟血液的本构关系是不够的。

Carotid arterial stiffness reflects the characteristic of the functional change of carotid artery in preclinical, and provides an earlier warning for those who tend to suffer cerebral infarction.

颈动脉僵硬度反映了临床前期颈动脉功能变化的特征，为脑梗死危险人群的预警提供了更早的信息。

Carotid body:a chemoreceptor located near the bifurcations of the carotid arteries that monitors changes in the oxygen content of the blood and helps control respiratory activity.

颈动脉体：位于颈动脉的分支点附近的化学感受器，监测血液中氧含量的变化并协助调控呼吸活动。

General hypothermia was produced in 27 rabbits under nembutal anesthesia by immersing in an ice water bath, during the course of which, the carotid blood pressure was registered, the depressor and pressor reflexes elicited by faradic stimulation of the central end of the depressor nerve and by temporary occlusion of one side of the carotid artery respectively were examined.

三选择性头部低温与全身低温一样地引起血管内感受性反射的减弱，这说明全身低温时的上述反射变化主要取决於低温对神经中枢的作用，而这种作用可能使中枢处於间生性抑制状态。

Methods The carotid artery system was dissected and the length of every segment from the crotch common carotid artery to every portion were measured with slide gaud under operating microscope in 15 Kunming mice.

在手术显微镜下，解剖小鼠颈动脉系后，用油标卡尺测定从颈总动脉分叉至各部的长度，结果以均数表示。并对尼龙单丝线末端的处理进行了较详细的研究。

Methods Under femoral artery puncture and catheter introducer leaving,bilateral common carotid artery angiography was pertormed with 4F HeadHunt or simmons angiographic catheter.We superselectively inserted the catheter to the branch of external carotid artery after confirming the bleeding site,hemorrhagic artery and externalinternal cranial dangerous anastomoses.

用Seldinger技术经股动脉穿刺，置入导管鞘，进4F HeadHunt导管或Simmons导管行双侧颈总动脉造影，明确出血部位，出血动脉及有无颅内外危险吻合后，将导管超选择性插入出血的颈外动脉分支。

Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

根据橡皮管的体外实验结果，利用超音波以及影像分析所得到的橡皮管尺寸，与实际尺寸间的误差只有3%，而使用超音波 B-mode 量测颈动脉的实验结果显示，在把颈动脉当作完全弹性体的假设下，所得到的 CIMT 硬度指标，於十位平均年龄为23.6岁的年轻健康男性中，结果与过去文献中常使用的 Peterson's elastic modulus 相比较，结果显示容易受到不同受试者间，不同的生理状态之影响，而在考虑受试者的 IMT 变化情况下，比能够反映更多的受试者颈动脉材料性质，因此得到了较为稳定的实验结果。

The parameters of internal carotid were mean of left and right internal carotid.

IMT的测量是在要求部位的血管后壁测三次，并取其平均值。

Methods 11 cases with injury of carotid artery including four cases of ruptured carotid arteries with bleeding at the extracranial segment and seven cases of traumatic carotid-cavelTlOUS sinus fistula and/or formation of pseudoanearysm at the intracranial segment were studied.All cases were Confirmed by digital subtraction angiogrophyand were treated by IMIT with stent-graft.

对11例经数字减影血管造影诊断的颈动脉损伤病人进行皿管内治疗，其中颅外段颈动脉损伤4例、颅内段颈内动脉损伤7例，均采用覆膜支架封闭颈动脉破裂口，1例覆膜支架置入后发生移位而改为经静脉途径应用弹簧圈栓塞。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
