Fibres and asbestos bodies in bronchoalveolar lavage fluids of asbestos sprayers.
The alveolar content of fibres and asbestos bodies was assessed by bronchoalveolar lavage (BAL) in 21 asbestos sprayers. Transmission and scanning electron microscopy (TEM and SEM) and two light microscopical (LM) methods, cytocentrifugation, and Millipore filtration were used. The subjects had been exposed mainly to crocidolite asbestos for an average of 2.8 (range 0.2-13) years in 1950-75. Th...
متن کاملAsbestos bodies in bronchoalveolar lavage in relation to asbestos bodies and asbestos fibres in lung parenchyma.
In Finland, unlike other countries, anthophyllite asbestos has been widely used due to its domestic production in 1918-1975. In this particular context, the aim of the present study was to analyse the relationship between asbestos bodies (ABs) in bronchoalveolar lavage (BAL) fluid and the concentration of ABs and the different amphibole asbestos fibres in lung tissue. Sixty five BAL lung tissue...
متن کاملAsbestos bodies in bronchoalveolar lavage fluids of brake lining and asbestos cement workers.
Asbestos body (AB) concentrations in bronchoalveolar lavage samples of 15 brake lining (BL) workers exposed only to chrysotile have been determined and compared with those from 44 asbestos cement (AC) workers extensively exposed to amphiboles. The mean AB concentrations (263 +/- 802 and 842 +/- 2086 AB/ml respectively) for those groups did not differ significantly but were much higher than thos...
متن کاملAsbestos bodies in bronchoalveolar lavage reflect lung asbestos body concentration.
Asbestos body (AB) countings on both bronchoalveolar lavage (BAL) fluids and digested lung tissue samples were performed in one hundred consecutive subjects submitted to a thoracotomy procedure, mostly for lung carcinoma. A good correlation (r = 0.73) was found between the two groups of values for the total group of subjects. When restrictive selection criteria were taken into account, such as ...
متن کاملAsbestos fibres in bronchoalveolar lavage fluid from asbestos workers: examination by electron microscopy.
The uncoated and coated fibre load in bronchoalveolar lavage (BAL) fluid was assessed using light microscopy, scanning electron microscopy, and x ray microanalysis in 15 subjects with previous, unprotected exposure to asbestos, including three with clinical and radiological evidence of asbestosis, and in 13 urban dwelling control subjects with no known occupational exposure to asbestos. The mea...
