Figure 6

Hematoxylin and eosin staining of lung sections after intratracheal instillation of fullerenes. Magnification ×100. (A) Negative control at 3 months (B) 0.2 mg fullerene-exposed lung at 3 months (C) 1 mg fullerene-exposed lung at 3 months (D) 0.2 mg nickel oxide-exposed lung at 3 months. (E) 1 mg fullerene-exposed lung at 6 months, (F) 1 mg fullerene-exposed lung at 6 months. Focal infiltrations of alveolar macrophages with strong pigment deposition were observed in alveoli, although almost neutrophil infiltration disappeared.
