Immunophenotyping of Bronchoalveolar Lavage Lymphocytes

Immunophenotyping of bronchoalveolar lavage lymphocytes.

Apoptosis of bronchoalveolar lavage lymphocytes in hypersensitivity pneumonitis.

The aim of this study was to look at the apoptosis of alveolar lymphocytes in hypersensitivity pneumonitis (HP). HP patients and normal unexposed controls were studied. The percentage of apoptotic lymphocytes was significantly lower in HP patients than in normal patients (37.4 +/- 3.4 versus 56.5 +/- 5.5% for Annexin V and propidium iodine detection methods and 0.4 +/- 0.1 versus 1.0 +/- 0.2% f...

Bronchoalveolar lavage.

Bronchoalveolar lavage (BAL) is a relatively new technique for assessment of the alveolar compartment of the lung. Its current clinical applications are the initial assessment of acute and chronic diffuse interstitial lung disease and the diagnosis of pulmonary infections, especially in the immunocompromised host. In addition, BAL provides information on the pathophysiology of diffuse interstit...

Bronchoalveolar Lavage

To investigate the safety of repeated bronchoalveolar lavage (BAL) and the variability of commonly measured parameters from BAL to BAL in the same subject, we performed a total of 59 BALs in 16 normal volunteer subjects. The BAL was performed with 120 ml (three aliquots of 40 ml) of room temperature, normal saline in a lingular subsegment. Four subjects had five BAL, three had four BAL, and nin...

Apoptosis resistant bronchoalveolar lavage (BAL) fluid lymphocytes in sarcoidosis.

BACKGROUND Sarcoidosis is a chronic granulomatous lung disease of unknown origin. The accumulation of activated T cells at sites of inflammation represents an early stage in granuloma formation. Since mechanisms governing the normal resolution of inflammatory processes are poorly understood, this study aimed to investigate the apoptotic phenotype of peripheral blood and lung T lymphocytes from ...
