Figure 2From: Lung inflammation following a single exposure to swine barn airPulmonary intravascular monocytes/macrophages. ED-1 antibody stained monocytes/macrophages in the lung septum (A, arrows and inset, bar = 50 μm) and morphometric quantification of septal cells positive for ED-1 antibody showed an increase in their numbers at 48 hours post-exposure compared to controls and other exposed groups (*, P < 0.05, Figure 2B). Pulmonary intravascular monocyte/macrophage (PIMM) shows gold particle (C, arrows) to indicate staining for ED-1 antibody (En- endothelium, Ep-epithelium and AS- alveolar space).Back to article page
