血流

Routine CT and MR examinations can only detect infracortical cerebral arteriosclerosis, whereas CT perfusion map ping images can detect evident slowed down cerebral focal blood flow

Cerebral perfusion was restored through innominate artery cannulation after excluding error of measurement.

继续血流降温到深低温进行手术。2例患者进行了上腔静脉逆行灌注脑保护。

Results: The renal perfusion was increased in diabetes group after the injection of alloxan. The PSI, AUC and ascending slope rate of the curve of the time-intensity curve were increased in 1w and 2w with decreased of HPT; the pathological examination exhibited glomeruli hypertrophy and no thickening of basal lamina. The PSI and AUC in 4w and 6w were more than that of control group; the PIT and ascending slope rate of the curve got closed to normal in 4w and 6w; the intercapillary cells increased. The speed of ascending slope rate of the curve in 8w, 10w and 12w was slower, shown as PIT and HPT delayed; the pathological examination showned increasing of mesangial cell, hyperplasia of mesangial matrix and thickening of basal lamina, followed with obliteration of partial micrangium, glomerular sclerosis and reduce of PSI in 12w.

结果：糖尿病组兔注射四氧嘧啶后肾皮质血流灌注增大，1周、2周表现为时间-强度曲线参数中峰值强度升高、曲线下面积增大、达峰时间缩短、曲线上升斜率升高，此时病理可见肾小球肥大，系膜基质正常，基底膜无增厚；4周、6周，峰值强度、曲线下面积高于对照组，达峰时间、曲线上升斜率接近正常，系膜细胞增多。8周、10周、12周，达峰时间延长、曲线上升斜率减慢、峰值强度减半时间延长，病理出现肾小球系膜细胞明显增多，系膜基质增生，基底膜增厚，至12周病理出现部分毛细血管管腔闭塞，肾小球节段性硬化，峰值强度测值减低。

The normal control were 30 healthy people. Renal interlobar artery systolic blood maximal velocity,end-di...

Methods the gene polymorphism of ACE in 108 patients were analyzed by using the polymerase chain reaction. Main renal arteries, segmental arteries and interlobar arteries in 108 patients were measured by color Doppler flow image.

用聚合酶链反应对甘肃地区108例糖尿病患者血管紧张素转换酶基因多态性进行检测，并对患者双肾肾主动脉、段动脉、叶间动脉进行彩色多普勒血流成像。

To measure the renal interlobar arterial bloodflow parameters via Doppler ultrasonography may act as an approach to the evaluation of renal function and the awareness of disease condition.

通过彩色超声多普勒法测定肾叶间动脉血流参数可以用来评价肾功能和把握肾脏疾病的状态。

Objective:To investigate the objective index of traditional Chinese medicine typing by means of analysis bilateral renal interlobar artery blood velocity in diabetic nephropathy patient using colorful Doppler frequency spectrum.

目的：借助彩色多普勒频谱图，对糖尿病肾病患者肾脏叶间动脉血流参数进行分析，探索该病中医分型的客观指标。

Methods:The blood flow spectrum of main renal arteries,segmental arteries,interlobar arteries and arcuate arteries were measured in 51 cases of serologically proved EHF and 40 normal subjects using color Doppler ultrasonography.

用彩色多普勒超声诊断仪检测了 40例正常人和 5 1例经血清学证实的 EHF患者，测定了病程中各期肾门部肾主动脉、段动脉、叶间动脉、弓形动脉的血流频谱参数。

Methods: After transferred pcDNA3.1/hTM plasmid into rabbit artery by high-pressure injection, rabbit common iliac artery were cut and anastomosed again. At the 14 days and 28days after second operation, we checked inside diameter of anastomotic stoma and blood flow velocity by color Doppler. The treated artery were sliced and stained by Verhoeff. Local neointima formation and the ratio stenosis of intervascular were calculated by computer.

用注射式加压转染的方式对兔动脉壁转染pcDNA3.1/hTM质粒，再制造动脉损伤-阻滞模型，于术后14天、28天用彩色多普勒观察活体吻合口内径和血流流速；再做病理切片Verhoeff染色，观察血管内膜增生的程度、部位，计算血管内膜面积、中膜面积和血管狭窄率。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
