FIG. 9.

Effects of splenectomy on ozone-induced expression of AT1R. Lung sections, prepared 24–72 h after exposure of CTL and SPX mice to air or ozone, were stained with antibody to AT1R. Binding was visualized using a peroxidase DAB substrate kit. Arrows indicate alveolar macrophages. One representative lung section from 3 mice/treatment group is shown. Original magnification, 600×.
