STUDY OBJECTIVES To define the clinical characteristics of the patients showing bronchoscopic findings of bronchial narrowing or obliteration with black pigmentation on overlying mucosa (we named this finding as "anthracofibrosis"), and to determine the association of anthracofibrosis with tuberculosis. PATIENTS AND METHODS The subjects of this study consisted of 28 patients; 8 men and 20 wom...
Early detection may help improve survival from lung cancer. In this study, our goal was to derive and validate a signature from the proteomic analysis of bronchial lesions that could predict the diagnosis of lung cancer. Using previously published studies of bronchial tissues, we selected a signature of nine matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) mass-to-charge...
The distribution of a new cephalosporin, cefdinir, in serum, epithelial lining fluid (ELF), bronchial mucosa and alveolar macrophages was studied in 17 adults following a single oral dose of 300 or 600 mg of cefdinir; tissue samples being obtained by diagnostic bronchoscopy approximately 4 h after this dose. Mucosal biopsies were taken, alveolar macrophages harvested by lavage, and ELF volume d...
Tissue kallikrein (TK) is secreted by serous cells of tracheobronchial submucosal glands and plays a role in allergic airway responses. To better understand the regulation of TK, we used primary cultures of submucosal gland cells that release TK upon stimulation. Media from cultures stimulated with chymase (10(-7) M) showed increased TK activity (0.50 +/- 0.22 mU/ml mean +/- standard error) in ...
OBJECTIVE Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) type is the most frequent type of non-Hodgkin's lymphoma to primarily involve the lung. Pulmonary MALT lymphoma, also known as bronchial-associated lymphoid tissue (BALT) lymphoma, is a rare disease and the clinicopathological features have yet to be clearly elucidated. PATIENTS AND METHODS The present stu...
Early detectionmay help improve survival from lung cancer. In this study, our goal was to derive and validate a signature from the proteomic analysis of bronchial lesions that could predict the diagnosis of lung cancer. Using previously published studies of bronchial tissues, we selected a signature of ninematrix-assisted laser desorption ionization mass spectrometry (MALDI MS) mass-to-charge r...
In this study, we investigated the expression of lipocortin I and II (annexin I and I in the human bronchial epithelium, both in vivo and in vitro. A clear expression of lipocortin I and II protein was found in the epithelium in sections of bronchial tissue. In cultured human bronchial epithelial cells we demonstrated the expression of lipocortin I and II mRNA and protein using Northern blottin...
Objective: The incidence of primary lung adenocarcinoma is increasing year by in worldwide, and it has surpassed squamous cell carcinoma to become the most common pathological type cancer. Advances medical technology have made overall survival rate cancer patients improve, but still very low. In study, we investigated methyltransferase SETDB1 expression methylation level SPG20, analyzed correla...
