  • Particle Penetration of the Skin as a Route of Sensitization in Occupational Lung Disease
    Particle Penetration of the Skin as a Route of Sensitization in Occupational Lung Disease
    Abrigo BA ;
    Adkins EJ
    2000/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Chronic Beryllium Disease (CBD) is an occupationally-acquired lung disease that begins as a cell-mediated immune response to beryllium particulates that, over time, results in development of non-caseating granulomas. During the last ten years, the beryllium industry has made major improvements in respiratory protection and engineering control techn ...

    2000/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    The antiarrhythmic drug amiodarone (AD) is limited in use by its pulmonary toxicity involving inflammation and fibrosis. The goal of this study was to further characterize an animal model of AIPT and to examine the possible mechanisms involved in the progression of toxicity. Male F344 rats were instilled intratracheally with AD (6.25 mg/kg with a 3 ...
