  • Coal Dust Is a Modifier of Pulmonary CYP1A1 Induction in Rats
    Coal Dust Is a Modifier of Pulmonary CYP1A1 Induction in Rats
    Barger M ;
    Battelli L
    2002/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Cytochrome P4501Al (CYP1A1) plays an important role in pulmonary carcinogenesis. Pulmonary CYP1Al metabolizes inhaled exogenous agents such as cigarette smoke-associated polycyclic aromatic hydrocarbons, into potent carcinogens. We hypothesized that intrapulmonary deposition of particulate might modify susceptibility to inhaled carcinogens by modif ...

    2002/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    Carbon monoxide (CO) is an odorless, colorless gas that can cause illness and death by asphyxiation. Although the toxicity of CO is understood, occupational CO exposure can occur from unrecognized sources. In a recent incident, three cases of CO poisoning in a confined space, including one fatality, were caused by CO migrating through soil after ne ...

    Lewis, Daniel M.
    2002/03/01 | National Institute for Occupational Safety and Health (NIOSH)
    TMA is a low-molecular-weight chemical that can induce production of specific IgE and occupational asthma in sensitized individuals. The respiratory tract is considered to be a major exposure route leading to immunological and airway sensitization, but the relationship between dermal exposure and subsequent airway responses to TMA is not known. Our ...

    Inhalation of residual oil fly ash (ROFA) impairs lung defense in susceptible populations. Bioavailability of soluble transition metals appears to play a key role in compromised lung defense caused by ROFA exposure. We evaluated the effect of soluble metals on lung defense in animals pre-exposed to ROFA followed by pulmonary challenge with a bacter ...
