Brochioalveolar fluid has emerged in laboratory medicine as a clinically important source of significance with recent progress of skilled sampling by brochoscopy and research work by histopathological, biochemical, immunological and moreover genetic analyses.
The best opportunity was initially given in the annual meeting by inviting three specialists engaged in clinical practice and research work on surfactant and clara cell 10 kilodalton protein.
