The effect of heavy, habitual marijuana use compared with tobacco smoking on the composition of bronchoalveolar and peripheral blood lymphocytic phenotypes was examined. Bronchoalveolar lavage (BAL) and peripheral blood (PB) samples were taken from 14 nonsmokers (NS), 14 tobacco smokers (TS), 19 heavy, habitual marijuana smokers (MS), and 9 marijuana and tobacco smokers (MTS). In BAL fluid, mar...

The expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was studied in seven patients with pulmonary sarcoidosis. By means of nuclear run on transcription assay, the transcriptional level of c-sis proto-oncogene in bronchoalveolar mononuclear cells was investigated. Expression of c-sis proto-oncogene in bronchoalveolar mononuclear cells was enhanced. Enhancement of c-sis tra...

BACKGROUND Bronchial mucosal inflammation and epithelial damage are characteristic features of asthma. Activation of T helper lymphocytes may contribute to this process by mechanisms including the release of cytokines promoting eosinophil infiltration and activation. METHODS Bronchial washings and bronchoalveolar lavage fluid were obtained from 29 atopic asthmatic patients (19 with current sy...

background and purpose: invasive aspergillosis (ia) is one of the most common life-threatening fungal infections among the critically ill patients including intensive care unit (icu) patients. delayed diagnosis and therapy may lead to poor outcomes. diagnosis may be facilitated by a test for molecular biomarkers, i.e. detection of galactomannan (gm) antigen based on enzyme immunoassay, which is...

pulmonary nocardiosis is an acute or suppurative chronic disease, caused by aerobic actinomycetes which usually originates from soil and compost. since nocardia species have been isolated from the soil of different regions of iran, as well as different cases of nocardiosis, this study was undertaken to evaluate the role and frequency of nocardia in pulmonary infections.the present investigation...

Bronchoalveolar lavage was performed in 97 patients including control patients with bronchial carcinoma (24) and patients with sarcoidosis (20), cryptogenic fibrosing alveolitis (9), and asthma (4), and others. Cytocentrifuged slides were stained by two methods: May-Grünwald Giemsa and toluidine blue. In the last 32 subjects the bronchoalveolar lavage fluid was separated into supernatant and ce...
