Neutrophil influx into lungs of A/J mice in response to sub-chronic V 2 O 5 . Neutrophils were detected by immunohistochemical staining using an anti-mouse neutrophil antibody in formalin fixed lung sections. A.) PBS-treated A/J mouse; B.) PBS-treated B6 mouse, C.) V2O5-treated A/J mouse, 1 day; D.) V2O5-treated B6 mouse, 1 day. Original magnifications ×100, insets ×200. Arrows indicate areas with positive staining for neutrophils (red-brown in color), dashed boxes indicate areas magnified within the insets.
