气管

The studies on the nymphs or larvae of 18 species belonging to Orthoptera, Mandotea, Homoptera, Hemiptera, Coleptera, Diptera and Hymenoptera indicate that the larvae of Argridae have the function of ""lungs"", but the nymphs or larvae of other orders may not have ""lungs"".

博莱霉素气管内滴入建立大鼠肺纤维化模型，正常对照组气管内滴入生理盐水。

Methods 25 Wistar rats were divided into control group (n = 5) and lidocaine group (n = 20),and rats in lidocaine group which received intratracheal injection of lidocaine were sacrificed at 2,24,48,and 72h (5 rats at each time point),then the samples of 1 / 3 lower parts of trachea were collected and observed by scanning electron microscope.

将25只Wistar大鼠随机分为正常对照组5只、利多卡因组20只，经大鼠气管穿刺注入利多卡因，并在2、24、48、72h4个时间点处死大鼠5只。取气管后1/3段的腹侧部，做扫描电镜观察大鼠气道黏膜表面结构。

Objectives To study the expressions of STAT1 and PDGF in lung tissue of pulmonary fibrosis model induced by bleomycin in rats, and discuss the possible mechanism.Methods Thirty Wistar rats were randomly divided into two groups (15 in each group), they were bleomycin group and control group.①The BLM group was intratracheally instilled with belomycin (5mg/kg);② NS group was intratracheally instilled with saline (5mg/kg).

目的 观察肺纤维化鼠肺组织信号转导和转录活化因子1（STAT1）和血小板源性生长因子表达的变化，探讨其在肺纤维化的作用机制方法 30只Wistar大鼠随机分博莱霉素组和对照组，①BLM组：气管内灌注BLM（5mg/kg）诱导肺纤维化；②NS组：气管内灌注NS。

Methods Ninety-six rats were randomly divided into four groups: normal saline was instilled intratracheally in control group; lipopolysaccharide was instilled intratracheally in other three groups, then vehicle (1% alcohol in saline) dexamethasone and MT were injected intraperitoneally in these groups, respectively.

方法96只大鼠随机分为4组：对照组气管内滴注生理盐水；另外3组气管内滴注等量脂多糖(lipopolysaccharide， LPS)，并分别腹腔注射溶媒、地塞米松(dexamethasone， DEX)和MT。

Methods Thirty Wistar rats were randomly divided into two groups (15 in each group), they were bleomycin group and control group.①The BLM group was intratracheally instilled with belomycin (5mg/kg);② NS group was intratracheally instilled with saline (5mg/kg).

30只Wistar大鼠随机分为博莱霉素组和对照组，①BLM组：气管内灌注BLM（5mg/kg）诱导肺纤维化；②NS组：气管内灌注NS。

5 And 5.0 mg/kg bleomycin were given intratracheally to every 15 mice in the bleomycin group, respectively. The mice in the control group were administrated the same volume of normal saline. Twenty-eight days after model establishment, all mice were sacrificed. Their left pulmonary lobe tissues were removed from mice and used for pathological section observation, and the right pulmonary lobe tissues were used for the hydroxyproline contents measurement. MAIN OUTCOME MEASURES: The survival condition of mice in 28 days.

60只小鼠随机数字表法分为博莱霉素组(n=45)和对照组(n=15)，博莱霉素组各选15只动物分别气管内注射不同剂量(2，3.5，5 mg/kg)的博莱霉素，对照组气管内注射相同体积的生理盐水，所有小鼠于造模后第28天处死并取其左肺叶制作病理切片，右肺叶作羟脯氨酸含量测定。

The proliferating cells were mainly distributed in the peri-chondrium and the peripheral zone of tracheal cartilage. The senescent chondrocytes were distributed in the central zone whereapoptotic morphological characteristics obviously appeared, such as pyknosis, karyorrhexis.

结果：软骨细胞呈现多种方式的无丝分裂像；气管软骨膜与软骨周围带多见细胞增生；气管软骨中央带多见衰老的软骨细胞，并见明显核固缩、核碎裂等细胞凋亡形态学特征。

Limited mouth opening prevented laryngoscopic orotracheal intubation; bronchofiberoptic nasotracheal intubation failed due to profuse oral bleeding.

因为他张口困难，我们无法进行喉头镜经口气管插管；光纤支气管镜经鼻气管插管则因患者口腔内大量出血而未能成功。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.
