Figure 1.
Effects of nitrogen mustard (NM) on CD11b and inducible nitric oxide synthase (iNOS) expression. Lung sections, prepared 1, 3, 7, and 28 days (d) after exposure of rats to phosphate-buffered saline control (CTL) or NM, were immunostained with antibodies to CD11b or iNOS. Binding was visualized using a Vectastain kit. Arrows indicate macrophage in insets. Original magnification, 60×; inset magnification, 200×. Representative sections from three rats/treatment group are shown.
