肺动脉

Methods The rat model of chronic hypoxia-hypercapnia pulmonary hypertension was adopted. The safflor injections were injected to the rats.

采用慢性低氧高二氧化碳肺动脉高压模型，应用红花注射液治疗，电镜观察大鼠脑超微结构并测定其SOD、MDA、XOD含量。

Observed the expression of Ps and ICAM-1 at 1, 6, 12 hour during normoxia, hypoxia and reoxygenation respectively and the effect of serum safflor injection on the expression of Ps and 1CAM-1 mRNA after reoxygenation.

目的观察含红花血清在缺氧复氧条件下对大鼠肺动脉内皮细胞P-选择素及细胞间黏附分子-1（ICAM-1）基因表达的影响，探讨肺栓塞溶栓后缺血再灌注损伤的机制。

Methods 36 infants with ventricular septal defect associated with pulmonary hypertension were randomly divided into two groups.

选取36例室间隔缺损合并肺动脉高压的婴幼儿患者，随机分为观察组和对照组，每组18例。

Objective To investigate the relationship of Tei index to pulmonary hypertension in patients with ventricular septal defect.

目的探讨Tei指数与室间隔缺损患者肺动脉高压的关系。

This article analysed the clinical manifestation and supplementary diagnostic methods in 8 patients with aortopulmonary septal defect.

本文分析了8例主－肺动脉间隔缺损病人的临床表现及辅助诊断方法。

Urokinase, tissue -type plasminogen activator and plasminogen activator inhibitor-1 expression in severely stenosed and occluded vein grafts with thrombosis.

组织型纤溶酶原激活物在兔实验性肺血栓栓塞肺动脉中表达的动态变化及临床意义。

Results After 2 or 6 hours of LPS intravenous administration, severe lung injury and positive signals of NT occurred with the latter located in the pulmonary macrophages, endothelia, subendothelial and muscular layers of the pulmonary artery.

结果 LPS静脉注射2 h和6 h 后，肺脏有明显损伤及硝基酪氨酸产生的阳性信号，该信号主要分布于肺泡壁巨噬细胞、肺小血管和细小支气管周围的巨噬细胞以及部分肺动脉的内皮细胞、内皮下层及肌层。

It will be more clinically significant that VSD is classified into perimembranous, conoventricular, atrioventricular canal or inlet, muscular and subpulmonary artery or conical types.

将室间隔缺损分为膜周型、圆锥隔心室型、房室通道型、肺动脉瓣下或圆锥隔型和肌部型更具有临床意义。

Their body weights ranged from 3.0㎏ to 5.0㎏(mean weight 4.1±0.8㎏) and their ages ranged from 27 days to 182 days (mean age 131±17 days). 21 infants had perimembranous VSD, 12 had subpulmonary VSD and 2 had multiple VSDs. The diameter of VSD was among 8 to 25 mm.

所有患儿均易发生呼吸道感染，伴有肺动脉高压，其中膜周型VSD12例，多发VSD2例，VSD直径8～25mm，均在全麻体外循环下手术治疗。

Spiral CT scanning is a noninvasive method for investigating, but is restricted in the sensitivity of exploring subsegment and distal pulmonary artery embolism.

螺旋CT检查是一种无创伤性的诊断方法，但对于在亚段及远端肺动脉内血栓敏感性是有限的。

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。
