| Gross and microscopic examination revealed bronchopneumonia and arteriosclerotic cardiovascular disease. |
| Enlarged and edematous lungs, consolidation, hemorrhage, bronchopneumonia, and acute bronchiolitis were also noted. |
| The lung showed focal bronchopneumonia, multiple thrombi, and focal hemorrhagic infarcts. |
| Most common finding is bronchopneumonia with patchy air-space areas of increased opacity. |
| In severe exposure, necrosis of the respiratory epithelium leads to formation of a pseudomembrane, bronchial plugging, and bronchopneumonia. |
| Sections showed early patchy bronchopneumonia, centriacinar emphysema, and desquamative interstitial pneumonitis. |
