  • Title: Nonrespiratory metabolic function and morphology of lung following exposure to polybrominated biphenyls in rats.
    Author: McCormack KM, Roth RA, Wallace KB, Ross LM, Hook JB.
    Journal: J Toxicol Environ Health; 1982 Jan; 9(1):27-39. PubMed ID: 6278155.
    Abstract:
    Exposure to polybrominated biphenyls (PBBs) resulted in increased activity of microsomal arylhydrocarbon hydroxylase and ethoxyresorufin-O-deethylase in rat lung. Clearance of 5-hydroxytryptamine (5-HT) and angiotensin 1 by perfused lungs was decreased by PBBs. However, PBBs had no effect on the activity of epoxide hydrolase, monoamine oxidase, or angiotensin-converting enzyme in lung. The only histopathologic change detected in lungs from PBB-treated rats was an increase in alveolar type II cell lamellar bodies. Selective accumulation of certain PBB congeners by lung was not observed in this investigation.
