Pre-infection levels of lavagable transferrin (solid bar/specific agent set) and ferritin (hatched bar/specific agent set) in lungs of rats that had been exposed for 5 hr/d for 5 days to soluble or insoluble forms of V or Cr. Each value reported is the mean (± SE) obtained from 5–10 rats/subset. At p < 0.05, *level significantly differs from air control value; ‡level significantly differs from solubility-matched Cr counterpart; #level significantly differs from soluble counterpart.
