Role of alveolar macrophages in asbestosis: modulation of neutrophil migration to the lung after acute asbestos exposure.

After intratracheal injection of short chrysotile asbestos fibres in guinea-pigs an intense neutrophil alveolitis was observed within three days. Evaluation by bronchoalveolar lavage of the inflammatory and immune effector cells producing the alveolitis by three days showed an increased proportion of polymorphonuclear leucocytes, which comprised 21% +/- 3… CONTINUE READING
