Lung - Infiltration Cellular, Histiocyte - Gallery

Lung - Infiltration cellular, Histiocyte in a male Wistar Han rat from a subchronic study. There is a small, subpleural accumulation of alveolar histiocytes.

Lung - Infiltration cellular, Histiocyte in a female Harlan Sprague-Dawley rat from a chronic study. There is a small, subpleural accumulation of alveolar histiocytes with some thickening of associated alveolar septae.

Lung - Infiltration cellular, Histiocyte in a control male F344/NTac rat from a subchronic study. There is a focal accumulation of histiocytes in several adjacent alveoli.

Lung - Infiltration cellular, Histiocyte in a control male F344/NTac rat form a subchronic study (higher magnification of Figure 3). Many of the alveolar macrophages in this focal accumulation contain variably sized vacuoles.
