title: The effect of automobile exhaust particulates on cell viability, plating efficiency and cell division of mammalian tissue culture cells.
abstract: Extract of particulate matter (EPM) of gasoline engine exhaust induced only a slight loss of cell viability of mouse macrophages (line IC-21) in vitro, while a strong dose-dependent reduction of plating efficiency of human cell line A-549 and of Syrian hamster line 14-1b occurred. Cytological investigations of exposed macrophages of line IC-21 revealed an increase in the mitotic index from 1.5% of control values up to 14.6% at the highest tested concentration of EPM. Mitotic arrest is based almost exclusively on C-type mitoses occurring dose-dependently in the presence of EPM. Results indicate disturbances of the spindle apparatus in the presence of EPM.
