Results The levels of IgE,IL-4and histamine in sera and the number of acidophilic cells in blood were all in-creased;The asphyxiant sign,the congestion and edema of the epiglottis,a large amount of the lightish yellow mucous fluid with some blood-filaments in the tracheae,pneumochysis,scattered petechiae on the inside surfaces and the bot-toms of both lung lobes were found;cerebromeningeal haemorrhage and cerebral edema were observed under microso-cope.

结果 检血中IgE、IL-4、组胺含量和嗜酸粒细胞数量均显著增加。死者呈窒息征象；气管喉头充血水肿，气管内有大量淡黄色夹有血丝的粘性液体，肺水肿，肺叶间及肺底部散在点状出血；脑膜出血和脑水肿。

Although tracheotomy has been a common and basic surgery in laryngology, it can result in a variety of complications. There have been many modifications in the past years.

气管切开术虽然是喉科学上常见的基本手术，但是仍有可能导致各种并发症，因此多年来在手术方法上有许多的修订和改良。

And there is an approximate linear relationship between the momentum of the automatic mechanism and the length of the gas tube.

如β=〓与β=〓相比较（β角单位为弧度，其定义详见正文），前者与后者对应的气室最大压力之比可达65%，而对应的自动机动能之比可达60%；导气管内径对气室内气体压力冲量和自动机动能的影响存在极值点，且该极值点随导气孔的增大而有规律的增大；导气管长度对气室最大压力、压力冲量和自动机动能的影响呈单调递减规律，且自动机动量与管道长度之间近似符合一直线关系。

The windpipe is situated in front of the oesophagus in all animals that have a windpipe, and all animals have one that are

气管位于所有有气管的动物的食管前面，而且所有动物都有一条和肺连接的气管。

However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。

The insects are tracheate arthropods in which the body is divided into head, thorax and abdomen

昆虫是有气管的节肢动物，体躯分为头部，胸部和腹部。

The in sects are tracheate arthropods in which the body is divided in to head, thorax and abdomen

昆虫是有气管的节肢动物，体躯分为头部，胸部和腹部。

Depending on the data source, this amounted to 2.4%, 3.1% or 3.4% of the total number of infants with esophageal atresia and tracheoesophageal fistula, a significant association.

根据这些数据源推测，总计有2.4%、3.1%或3.4%的婴儿有食管闭锁和气管食管瘘，表明服用DES和这些先天缺陷间有明显的联系。

ConclusionUrapidil,phentolamine and glyceryl trinitrate and inhibit the tension of isolated tracheal smooth musde in rabbits.Phenylephdrinum has no effect on the isolated smooth muscle tension.

乌拉地尔、酚妥拉明、硝酸甘油对兔离体气管平滑肌张力有显著的抑制作用，适用于气管高敏反应患者；去氧肾上腺素虽无明显影响，但应慎用。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。
