Figure 1: Chronic ethanol ingestion changes the landscape of the alveolar epithelium. 40X original magnification of white light illumination of trichrome-labeled cryoslices obtained from maltoedextrin-fed (control; top) versus chronic EtOH-fed mouse lung (Meadows-Cook model; bottom). ( ) indicates inflamed area with exudate. Arrow points to alveolar macrophages inside airway. Note collapsed airway in Meadows-Cook alcohol mouse model versus control-fed animal.
