血流量

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

Objective To investigate the regional cerebral blood flow in amnestic mild cognitive impairment and vascular cognitive impairment-no dementia subjects.

目的 探讨遗忘型轻度认知损害和非痴呆血管性认知损害的局部脑血流量改变的特征。

Results （1）The blood flow ofthe microvasˉcular in the antebrachium and hand increase after electrical acupuncture,and the increase after electrical acupuncture continue for the longest time.

结果 电针后，前臂和手部的微循环血流量明显增加，并持续较长时间。

The utility of routine serial CK monitoring after primary PCI, in which normal antegrade blood flow is restored in most patients, is unknown.

绝大部分患者在直接PCI术中保存了正常的前向血流量，因此，常规的连续性的肌酸激酶监测的效用尚不清楚。

Small artery and arteriole are the main position of organism to regulate the organ blood flow and the redistribution of blood among apparatus.

小动脉和微动脉是机体调节器官血流量和器官之间血液重新分配的主要部位，其血管的口径受神经体液因素的调节。

A formula was designed for regional cerebral blood flow loss index following arteriostenosis when arteriostenosis index formula was deduced; the former may provide a reference to assess cerebral function.

在推导动脉狭窄指数公式中，发现动脉狭窄后局部脑血流量丧失指数的计算方法，试图为评估脑功能提供参考。

Regional cerebral blood flow within 24 hours was detected and diameter of basilar artery was observed.

对SAH 组和假手术组检测24小时内局部脑血流量，并观察基底动脉管径。

Methods: We selected 71 patients with acute hemorrhagic stroke as the study group who were hospitalized within 24 hours after onset in the 1st 3rd 5th 7th 9th 11th 13th 15th day of hospitalization and prior to the usage of dehydrant. We selected 30 normal people as the control group. We collected the data of cerebrovascular hemodynamic index including cerebral blood flow and velocity, cerebrovascular resistance, cerebrovascular elasticity ,dynamic resistance and critical pressure for each patient . We compared the data between the study group and control group ,also we compared the data in the different time after disease onset and the data of affected side and non-affected side by using SPSS software.

选择急性出血性脑血管病患者71例为观察组，正常人30例作为对照组，观察组以发病时间为起点，分别在发病后第1、3、5、7、9、11、13、15天且在使用脱水药前行脑循环动力学检测仪检测获得脑循环动力学参数，包括血流速度、血流量、血管弹性指标，血管阻力、血管调节功能指标动态阻力及临界压力数值，对观察组和对照组的各项数值进行比较，及观察组在发病后的不同时间进行前后比较，且对患侧和健侧数值之间进行比较，所得数据使用SPSS软件处理。

Objective:We use an objective method to evaluate the effect of isosorbide dinitrate on myocardial blood flow of ischemic area.

目的：临床上应用一种较客观简单方法评价硝酸异山梨酯改善冠心病缺血区域血流量的作用。
