Image of acute inflammation in the lung from a male Wistar Han rat in a subchronic study
Lung - Inflammation, Acute in a male Wistar Han rat from a subchronic study. The majority of the inflammatory cells are neutrophils; there is also a small amount of hemorrhage.

Lung - Inflammation, Acute in a male Wistar Han rat from a subchronic study (higher magnification of Figure 1). The majority of the inflammatory cells are neutrophils, but there are also mononuclear cells, including alveolar macrophages.
Image of suppurative inflammation in the lung from a male Wistar Han rat in a chronic study
Lung - Inflammation, Suppurative in a male Wistar Han rat from a chronic study. Large numbers of degenerate neutrophils fill and replace alveoli.

Lung, Bronchiole - Inflammation, Suppurative in a male B6C3F1/N mouse from a chronic study. Degenerate neutrophils fill the bronchiole.
Image of suppurative inflammation in the lung from a female B6C3F1/N mouse in a chronic study
Lung - Inflammation, Suppurative in a female B6C3F1/N mouse from a chronic study. There are numerous large, foamy, activated alveolar macrophages amid the degenerate neutrophils.

Lung - Inflammation, Chronic in a female B6C3F1/N mouse from a chronic study. The mononuclear inflammatory cells are largely perivascular, peribronchiolar, and subpleural.

Lung - Inflammation, Chronic active in a male F344/N rat from a subchronic study (higher magnification of Figure 13). There is a mixture of lymphocytes, macrophages, and neutrophils, with a small amount of alveolar hemorrhage.
Image of chronic-active inflammation in the lung from a male F344/NTac rat in a subchronic study
Lung - Inflammation, Chronic active in a male F344/NTac rat from a subchronic study. The perivascular and interstitial inflammation in this control rat is consistent with Pneumocystis carinii infection (formerly rat respiratory virus).
