To maintain an adequate airway in a patient with tracheobronchial narrowing coming from various causes, prosthetic tracheobronchial stents provide palliative treatment for narrowed airways where surgical resection is inadvisable. After insertion, previous reported complications were granuloma formation, dysphagia, suction catheter entrapment and fatal massive hemoptysis. We report, a case of complication associated with expandible metallic stent with endobronchial stenosis due to tuberculosis.

The Korean airspace is very much limited, but its users are many. Especially many special using airspaces for military aircraft are formulated within the Taegu Flight Information Region and it is so restricted for civil aircraft to use the military airspaces. However, as the demand of civil air traffic is increasing, positive cooperation among the users of the airspace is needed to cope with the demand and to uplift the utilitation of the Korean airspace. Most of airspace except airways within the FIR are restricted areas, prohibited areas or operation areas for the military purpose. This thesis shows how to improve the utilitation of the Korean airspace and how much economical benefit the suggestion gives.

A possible asymmetry in airway inertance was modeled based on previously reported radiographic visualization data of the airway wall fluctuation in intact dogs. Effects of asymmetric Inertance on mean lung volume during high frequency ventilation (HFV) were evaluated in terms of mean inertive pressure drop across the airways. It was found that a negligible inertlve pressure drop was expected ($<1{\;}cmH_20$) in normal subjects, while a sig- nificant rise in mean alveolar pressure compared to mean mouth pressure by approximately $3{\;}cmH_20$ was resulted for about 40% airway fluctuation representing bronchoconstriction state by Histamine induction. These results demonstrate that asymmetric Inertance could lead patients with airway diseases to a significant lung hyperinflation (LHI), and bronchodilation treatment is recommended prior to applying HFV to prevent those patients from a possible barotrauma.

Objectives: Acute bronchitis is a common inflammatory disease with symptoms related to temporary inflammation of the airways. It is caused by a viral infections in over 95% of cases. A small minority of cases are caused by bacteria; however, there is little evidence that antibiotics are effective in the treatment of the condition. This report is a case of administering Dojukgangki-tang to three patients with acute bronchitis. Methods: Patients diagnosed with acute bronchitis were treated with Dojukgangki-tang, and the effects were studied using the bronchitis severity scale (BSS) and acute bronchitis severity scale (ABBS). Results: After treatment with Dojukgangki-tang for 2 weeks, average BSS score changed from $11.33{\pm}2.08$ to $1.67{\pm}1.15$. Average ABSS score decreased from $9.00{\pm}3.00$ to $2.00{\pm}1.00$. Conclusions: This study suggests that Dojukgangki-tang is effective in relieving coughs and sputum related to acute bronchitis.

Mucoepidermoid carcinoma of the lung is extremely rare. This rare tumor arise beyond the carina, usually main stem bronchi, but occasionally in lobar or segmental airways, This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is an uncommon, therefore complete surgical resection is the treatment of the choice. The prognosis of this tumor correlates with the histologic grade of the tumor. We experienced a case of mucoepidermoid carcinoma arising from the right middle lobe, which was treated with the right middle lobectomy, with good result. We report this case and follow-up of the patient.

Asthma is a disease of the airways that is characterized by increased responsiveness of the tracheobronchial tree to a multiplicity of stimuli. A number of causes have been postulated for the increased airway reactivity of asthma is conservative as beta-adrenergic agonist, methylxanthines, glucocorticoids, anticholinergics and mast cell stabilizing agent. Stellate ganglion block for the treatment of bronchial asthma has its controversies. Stellate ganglion block was performed for the treatment of 3 patients with bronchial asthma. After stellate ganglion blocks, dyspnea, coughing and wheezing was markedly reduced. Lung function test improved with 1 st case. Two asthma cases were able to discontinue medication for asthma. No severe aggrevation of bronchial symptoms were noted after stellate ganglion blocks. It suggested that stellate ganglion block can be safely performed on bronchial asthmatic patients.

Infection that progresses to deep areas of the neck requires appropriate assessment of the airway, and securing of the airway is critical in patients with deep neck infection. In the patient in our case report, bilateral pneumothorax occurred while performing tracheostomy to the airways of a patient with deep neck infection, and therefore, this paper details the method used to secure the airway of patients with deep neck infection.

Endobronchial ultrasound guided transbronchial needle aspiration is a recently introduceddiagnostic method which enables real time aspiration of peritracheal and peribronchial lesions. The high sensitivity and the high diagnostic accuracy of EBUS-TBNA in the mediastinal staging of lung cancer have been reported. EBUS-TBNA also showed the high diagnostic yield in the diagnosis of lung parenchymal masses adjacent to the trachea or the large airways. EBUS-TBNA is a good diagnostic method for mediastinal diseases, such as sarcoidosis. Until now, no major complications of EBUS-TBNA have been reported. EBUS-TBNA should be considered for the mediastinal staging of lung cancer and the diagnosis of mediastinal lymphadenopathies.

Burkholderia cepacia is an important pathogen that often causes pneumonia in immunocompromised individuals. Here, it was demonstrated that the TLR5 agonist flagellin could locally activate innate immunity. This was characterized by rapid expressions of IL-$1{\beta}$, TNF-${\alpha}$, and iNOS mRNA and a delay in the expression of IL-10 mRNA. A significant elevation in the IL-$1{\beta}$, TNF-${\alpha}$, and nitric oxide levels was also noted. In the respiratory tract, flagellin induced neutrophil infiltration into the airways, which was observed by histopathological examination and confirmed by the neutrophil count and level of myeloperoxidase activity. This was concomitant with a high activity of alveolar macrophages that engulfed and killed B. cepacia in vitro. The flagellin mucosal treatment improved the B. cepacia clearance in the mouse lung. Thus, the present findings illustrate the profound stimulatory effect of flagellin on the lung mucosal innate immunity, a response that needs to be exploited therapeutically to prevent the development of respiratory tract infection by B. cepacia.

Pulmonary conjugation pathways may be important for the metabolism of xenobiotics introduced via airways of systemically. The objective of this study was to determine the pulmonary conjugating capacity in both the isolated perfused rabbit lung (IPRL) and in vitro, and the ability of ethanol to alter the above. The IPRL was capable of conjugating glutathione (GSH) with either 1-chloro-2,4-dinitrobenzene (CDNB) of 1,2-epoxy-(p-nitrophenoxy) propane(ENP). The pulmonary GSH conjugation with ENP was inhibited by cibacron blue, indicating the presence of glutathione-S-transferase (GST) u and/or classes, but it was not altered by buthionine sulfoximine, a selective inhibitor of Gamma-glutamylcysteine synthetase.
