FIG. 2.

Male rat left lung histology. To visually assess pulmonary responses to C₆₀ exposure in male Sprague Dawley rats, sections of the left lung (8 μm) were stained with H&E and examined by light microscopy at 10× and 40× (inlays) magnification. (A) Representative images from a naïve male rat. (B) Representative images from a male rat intratracheally (IT) exposed to the PVP vehicle. (C) Representative images from a male rat IT exposed to C₆₀. (D) Representative images from a male rat intravenously (IV) exposed to vehicle. (E) Representative images from a male rat IV exposed to C₆₀.
