肺动脉

We found for the first time that the epithelium of bronchus of normal broilersexpressed iNOS mRNA.iNOS activity in the epithelium of bronchus of preascitic andascitic broilers were higher than normal broilers,but there was no iNOS activity inpulmonary vessels of all the three types broilers.The results indicated that the increasedNOS expression in pulmonary vessels of preascitic and ascitic broilers was not iNOS.

首次发现在肉鸡肺动脉高压发展过程中，肺血管NOS的表达是增加的，尤其是正常鸡无NOS表达的肺小血管内皮和平滑肌在腹水鸡却呈高水平表达，且NOS活性增加的肺小血管也同时存在管壁平滑肌层增厚或无肌型血管肌化的结构重建现象，结果提示NOS表达增强可能与肺血管中膜增厚有关。

In comparison with normal broilers,the preascitic and ascitic broilers had lowerPO2,O2 saturation,and pH levels,lower venous O2 content,but had higher CO2 content inboth arterial and venous blood,higher arterial O2 content and higher tissue O2 extractionindex.

本研究测定了这三种肉鸡的平均肺动脉压、平均右心室压、心电图II导联S和RS波幅、动静脉血血气、红细胞压积、右心肥大指数，并分析了这些指标之间的相关性。

The present study suggests that endogenous PAF may play a certain role in. maintaining low pulmonar...

提示PAF的舒血管反应通过受体起作用，内源性PAF在维持肺动脉低张状态中可能起一定的作用，而在HPV中不起主要作用。

How many cusps are there supposed to be on this pulmonic valve.

你认为这个肺动脉瓣有多少个瓣叶？

Every patients was observed for his heart and pulmonary function recovery,blood gas analysis and pulmonic pressure.

观察心肺功能恢复情况，检查血气分析和肺动脉压力。

As a result, the outflow of right ventricle is into the aorta and the outflow from the left ventricle is into the pulmonic trunk.

结果导致右心室的血流进入主动脉而左心室的血流则进入肺动脉。

When the spiral septum fails to completely descend, the aortic and pulmonic trunks are left undivided at their outflow.

一旦螺旋形隔板下降不全，主动脉和肺动脉干的血流将不能分开。

The prevalences of tricuspid and pulmonic regurgitation increased with age, reached the peak values at the age of 8-9 years of age, and decreased gradually afterwards.

三尖瓣、肺动脉瓣返流的发生率随年龄增长而增加，8～9岁时达高峰，随后渐下降；二尖瓣及主动脉瓣返流发生率随年龄改变不明显。

Moderate regurgitation was detected in pulmonic, tricuspid and mitral valves.

中度返流仅见于肺动脉瓣、三尖瓣和二尖瓣。

It can improve the pulmonary ventilation ,promote the respiration gas exchanges in lungs and decrease the high pressure in pulmonic vessels as well.

结合文献综述，探讨分析了太极拳运动特殊的呼吸方法对呼吸功能的改善作用，认为太极拳运动呼吸方法有利于改善肺通气及肺换气状况，降低肺动脉高压状态，此为太极拳运动对慢性呼吸系统疾病保健康复作用的关键因素。

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。
