气道

Through the analysis of different cross section flow field in cylinder of two-valve and four-valve diesel engine, the following conclusion can be obtained: The formation of intake swirl of two-valve diesel engine mainly is effected by an intense air flow ring zone near the radius from valve axis to cylinder axis, as the flow progresses down through the cylinder, the ring zone air flow expends to both side and finally forms an unified rigid rotating swirl motion.

2号缸盖的螺旋进气道产生的绕自身气门轴线的动量矩比1号缸盖的大，且切向气道的径向速度在前峰面上的数值比1号缸盖的速度数值大很多，因此，两进气道组合后的动量矩损失也大，所以虽然2号缸盖的两个进气道单独的涡流比都高于1号缸盖的两个进气道，但组合后的合成涡流比却是基本相同的。

Objective To study the effect of signal transducer and activators of transcription 5(STAT5)on airway inflammation of rats with asthma.

目的探讨信号转导子和转录激活子5(STAT5)在哮喘气道炎症中的作用。

Because levels ofserine proteinases in the airspaces are also dramatically increased,we hypothesized that these enzymes play a role in degradinglung antioxidants.

Apnoea is when the airway collapses and is blocked completely, cutting off the flow of air.

呼吸暂停症是当气道崩溃，是完全封锁，切断了流通的空气。

As people with sleep apnoea fall asleep, the muscles in their airway relax.

随着人们睡眠呼吸暂停入睡，肌肉在其气道放宽。

Objective To investigate the influence on upper airway of mandibular advancement splint in a group of obstructive sleep apnoea patients.

Objective Pseudomonas aeruginosais a Gramnegative bacterium that colonises the lower rspiratory tract in patients with bronchiectasis,cystic fibrosis and chronic obstructive pulmonary disease.

目的 铜绿假单胞菌(Pseudomonas aeruginosa，PA)是一种定植于支气管扩张、肺囊性纤维化和慢性阻塞性肺病病人下呼吸道的机会致病菌，可持续刺激宿主免疫反应导致进展性的气道破坏，具有多重耐药的特点，一旦感染，临床治疗十分困难。

The effect of curcumine on airway inflammation in asthmatic rats may be correlated with its inhibition on over expression of GM-CSF in lung tissue.

姜黄素可抑制哮喘大鼠的气道炎症，其作用机制可能是通过抑制GM-CSF的表达而导致嗜酸性粒细胞生成减少及存活时间缩短来实现。

Result 1、The effect of acupoint external application on the bronchial pathological structure and airway inflammation score of passive smoking rat The result showed:in model group,we conld see tracheal and bronchial mucosa bronchial exuviated,struction arranged in disorder,cilia lodged,even exfoliated in various degree,the exudate of airway cavity increased,alveolar wall capillary congested,bronchial wall seed a large amount of inflammatory cells,such as macrophage、lymphocyte、neutrophil,etc.

研究结果 1、穴位敷贴对被动吸烟大鼠肺组织结构及炎症病理评分的影响结果显示，模型组气管、支气管黏膜上皮脱落，结构排列紊乱，纤毛倒伏，甚至有不同程度的脱落，气道腔内渗出物增多，周围肺泡壁毛细血管充血，支气管壁见大量巨噬细胞、淋巴细胞、中性粒细胞为主的炎性细胞侵润等现像。
