Asbestos 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 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 کاملChronic cough in children: bronchoalveolar lavage findings.
Isolated chronic cough in childhood is a common complaint. Although the symptom cough is included in the definition of clildhood asthma, there is debate as to whether the majoritv of these children have asthma. The authors studied children with isolated chronic cough looking for evidence of airway inflammation typical of asthma, with increased numbers of airway eosinophils as assessed from bron...
متن کاملFibres 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 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...
