肺动脉

By using β-NADPH-diaphorase histochemical staining technique,wefound for the first time that NOS activity was detected in the epithelium of airpathway and endothelium of vessels but was not detected in the small vessels(ID＜100μm),and the NOS express in pulmonary vascular endothelium of preascitic andascitic broilers were elevated,especially in the endothelium and smooth muscle layer ofsmall vesseles with thicker walls and of muscularized nomuscular artery in asciticbroilers.

本研究从田间自然发生腹水症的肉鸡群中选取正常肉鸡、亚临床腹水鸡和腹水鸡为实验对象，通过比较这三种肉鸡血流动力学、心电图、动静脉血血气、肺外动脉舒张反应性、肺血管结构以及肺组织一氧化氮合酶的活性和分布等方面的不同，探讨了肺动脉舒张能力在肉鸡肺动脉高压形成中的作用和机制。

Note that the atheromatous plaques of the pulmonar artery intima at the right are indicative of the effect of such embolization --pulmonary hypertension.

图示右侧为肺动脉粥样硬化形成的粥样斑块，提示此种栓塞可引起肺动脉高压。

They are associated with stenosis of either the aortic or the pulmonic valve, with hypertension or dilatation of either the aorta or the pulmonary artery or both.

喷射性喀喇音喷射性喀喇音音调高，出现于收缩早期，与主动脉瓣或肺动脉瓣狭窄有关，也与主动脉瓣或肺动脉瓣或两者的高血压或膨胀有关。

Twenty infants had perimembranous VSD, one had infracristal VSD, 12 had subpulmonary VSD and two had multiple VSD. The diameters of VSD were 8 to 25 mm. All cases were operated under cardiopulmonary bypass.

所有病儿均易发生呼吸道感染，伴有肺动脉高压，其中膜周型VSD者20例，嵴内型VSD者1例，肺动脉瓣下VSD者12例，多发VSD者2例，VSD直径8~25 mm，均在全麻体外循环下手术治疗。

The incision of right ventricle was closed directly in 90 cases, in 52 cases only right ventricle outflow tractwas widen, RVOT and main pulmonary were enlarged separately with two patch in 2 cases ,and transannular patch was implanted in 171 patients.

318例TOF根治手术中，90例修补室缺后直接缝合右室切口，52例补片加宽右室流出道；2例用两块心包补片分别加宽主肺动脉和瓣下流出道；行跨肺动脉瓣环补片171例。

They underwent different surgical approach of fight ventricular outflow tract construction according to preoperation condition, 15 cases underwent staged radical repair in which transannular patching with homovariant pericardial flake.

一期根治术组32例，大部分病例采用自体心包片跨瓣环水平扩大右室流出道至肺总动脉，其中4例带心包单瓣，合并主肺动脉侧支的11例中有2例完成肺动脉血管的单元化手术。

The intrapulmonary arteries especially arterioles are more important for vasoconstricting response to hypoxia , but it is very difficulty to isolate them from the lung.

我们以往通过对常压缺氧大鼠模型的肺组织和肺动脉肾上腺素受体(Adrenoceptor，AR)亚型及其基因表达的一系列研究，初步认为AR亚型基因表达变化在低氧性肺动脉高压发病中可能起重要作用。

Purpose 1. To analyse the difference of going position and morphometry of pulmonary artery and pulmonary vein of pig lung ,by anatomizing them respectively.

目的 1。对猪的肺动脉、肺静脉进行分别解剖，分析肺动脉、肺静脉走行位置、形态学的差异。2。

ONOO〓 had direct vasoactive effect for relaxation of precontracted isolated pulmonary artery. Relaxing action of ONOO〓 was weak and was negtively regulated by endothelial cells, further supporting the notion that ONOO〓 may be involved in pulmonary hypertension in the early stage of ES.

用离体血管环检测张力方法，发现ONOO〓具有一定的舒张肺动脉作用，但舒张效应较弱，并受到血管内皮细胞的抑制性调节；抑制K〓通道和PARS活性可增强ONOO〓对离体兔肺动脉的舒张作用。

Results and Conclusion Our study showed that it is necessary to anatomise and authenticate the bodies that were caused by pulmonary embolism according to pivotal problems. Toxicosis,mechanical injury and some diseases must be excluded to provide direct qualitative evidence for the cases of pulmonary embolism.

结果及结论在肺动脉栓塞猝死的法医学鉴定中，除应结合检验鉴定要点全面地进行系统仔细的尸体解剖、病理组织学检验外，还应排除中毒、机械性损伤等暴力死和其他疾病死，为肺动脉栓塞的定性提供直接证据。

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。
