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.
Lung - Inflammation, Suppurative in a male Wistar Han rat from a chronic study. Large numbers of degenerate neutrophils fill and replace alveoli.
Lung - Inflammation, Suppurative in a male Wistar Han rat from a chronic study (higher magnification of Figure 3). Abundant necrotic debris is admixed with the degenerate neutrophils.
Lung, Bronchiole - Inflammation, Suppurative in a male B6C3F1/N mouse from a chronic study. Degenerate neutrophils fill the bronchiole.
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 in a female B6C3F1/N mouse from a chronic study (higher magnification of Figure 7). Mott cells are visible amid the lymphocytes and plasma cells in the subpleural region.
Lung - Inflammation, Chronic in a male F344/N rat from a subchronic study. These focal, subpleural lesions are a common background finding.
Lung - Inflammation, Chronic in a male F344/N rat from a subchronic study. This is a slightly more severe example of the common background lesion shown in Figure 9, with thickening of the alveolar septa.
Lung - Inflammation, Chronic in a female B6C3F1/N mouse from a chronic study. Numerous cholesterol clefts and pigmented macrophages are present in this inflammatory lesion.
Lung - Inflammation, Chronic in a female B6C3F1/N mouse from a chronic study (higher magnification of Figure 11). The macrophages are large, foamy, and activated.
Lung - Inflammation, Chronic active in a male F344/N rat from a subchronic study. There is a mixture of lymphocytes, macrophages, and neutrophils.
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.
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).
Lung - Inflammation, Chronic active in a male F344/NTAC rat from a subchronic study (higher magnification of Figure 15). The lesion is consistent with Pneumocystis carinii infection (formerly rat respiratory virus).
Lung - Inflammation, Chronic active in a male B6C3F1/N mouse from a subchronic study. There is a mixture of inflammatory cell types, including neutrophils, and alveolar proteinosis.
Lung - Inflammation, Granulomatous in a male Wistar Han rat from a chronic study. Clusters of large, foamy macrophages are surrounded by mononuclear cells.
Lung - Inflammation, Granulomatous in a female F344/NTAC rat from a subchronic study. There are numerous multinucleated giant cells in this lesion.
Lung - Inflammation, Granulomatous from a female F344/NTac rat in a subchronic study (higher magnification of Figure 19). The multinucleated giant cells are of the Langhans type.
