The anti-inflammatory action of silver nanoparticles (NPs) has been reported in a murine model of asthma in a previous study. But more specific mechanisms of silver NPs in an attenuation of allergic airway inflammation have not yet been established. Vascular and mucous changes are believed to contribute largely in pathophysiology in asthma. Among various(More)
The use of silver in the past demonstrated the certain antimicrobial activity, though this has been replaced by other treatments. However, nanotechnology has provided a way of producing pure silver nanoparticles, and it shows cytoprotective activities and possible pro-healing properties. But, the mechanism of silver nanoparticles remains unknown. This study(More)
A 20-year-old man presented to our outpatient clinic with hemoptysis, cough, and pleuritic chest pain. His chest radiograph and pulmonary function tests (PFT) were normal. A bronchoscopy showed a small yellowish patch with a regular surface. A direct bronchoscopic biopsy was performed. The pathologic findings showed a benign granular cell tumor. The(More)
Spontaneous regression (SR) of cancer is defined as a complete or partial, temporary or permanent disappearance of all or at least some relevant parameters of malignant disease with inadequate or no treatment. SR of cancer is an extremely rare phenomenon. We report a case of a 67-year-old man who experienced SR of non-small-cell lung cancer (NSCLC), which(More)
Both systemic lupus erythematosus and Sjogren's syndrome are autoimmune diseases. Almost all organs can be involved but the gall bladder is an unusual site. We report a 39-year-old woman with systemic lupus erythematosus and Sjogren's syndrome presenting with acute acalculous cholecystitis. It is a very rare complication and, in the literature review,(More)
Correspondence To the Editor: The anti-tuberculosis (TB) therapy can cause various drug adverse effects including hepatotoxicity, nephrotoxicity and skin rash. There are some case reports about interstitial lung disease (ILD) such as pneumonitis caused by isoniazid (INH), rifampin (RFP), ethambutol (EMB). The causative drug was discontinued permanently or(More)
BACKGROUND The efficacy of epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy can be measured based on the rate of treatment response, based on the Response Evaluation Criteria in Solid Tumors (RECIST) criteria or progression-free survival (PFS). However, there are some patients harboring sensitive EGFR mutations who responded(More)
The aim of the study was to evaluate the prevalence of restrictive ventilatory defect and to determine the risk factors in subjects with spirometrically-defined restrictive ventilatory defect. We used the population-based, fourth-2, 3 (2008, 2009) and fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) to analyze 15,073(More)
Third and fourth line chemotherapy agents are not helpful in the setting of extensive stage small cell lung cancer (SCLC). We describe the case of a 43-year-old Korean patient with T4N3M1b extensive stage SCLC who responded remarkably well to treatment and experienced a prolonged progression-free survival (PFS) period following treatment with fourth line(More)
Atypical adenomatous hyperplasia (AAH) has been considered to be a precursor lesion of bronchioloalveolar carcinoma (BAC) and pulmonary adenocarcinoma. It usually coexists with BAC and/or an adenocarcinoma. Chest computed tomography reveals multiple well-defined nodules with ground-glass opacity. Usually, AAH does not exceed 10 mm in size. AAH with(More)
