The lung biological activity of American attapulgite
…not an inert material for lung tissue; it does produce a macrophagic and neutrophilic alveolitis in the early inflammatory phase of lung reaction with peribronchiolar involvement in some sheep. Whether or not this initial attapulgite induced…

Contributions of experimental asbestosis in sheep to the understanding of asbestosis
…to 5 years. The authors described four tissue reactions to asbestos: no-retention, low-retention, high-retention and intermediate. They suggested that the intermediate reaction might explain non-progressive cases of minimal asbestosis. Exposure dose and…

Selective exposure and analysis of the sheep tracheal lobe as a model for toxicological studies of respirable particles
…at Day 1) and only macrophages after; lung histology documented an early macrophagic alveolitis which decreased to less than 10% of the initial inflammatory reaction at Day 60, without other distortion of the lung and airway…

Biochemical components of bronchoalveolar lavage in early experimental asbestosis of the sheep: phospholipase A2 activity, prostaglandin E2 and proteins
…significantly increased in both low and high dose groups. These changes in protein and lipid components of BAL following asbestos exposure constitute early indices of lung inflammatory reactions which may contribute to the development of asbestosis.
