Figure Lengend Snippet: Representative tissue sections stained for iron at days 1, 7, and 28 following inhalation exposure to Fe 2 O 3 nanoparticles in rats. Only the high-concentration group (4.92 mg/m 3 ) was displayed to show the time-course distribution. A – D Lung sections from ( A ) vehicle control, ( B ) day 1, ( C ) day 7, and ( D ) day 28 of the recovery period. E – H LALN sections from ( E ) vehicle control, ( F ) day 1, ( G ) day 7, and ( H ) day 28 of the recovery period. I – L Spleen sections from ( I ) vehicle control, ( J ) day 1, ( K ) day 7, and ( L ) day 28 of the recovery period. The blue-stained signals (arrows) denote ferric iron deposition. Scale bar: 25 μm
