Figure 3

Correlation between instilled surface area (vehicle, 0.54 μg gold, 54 μg C ₆₀ , 54 μg CB and 54 μg SWCNT) and the fold induction on linear (A, B) and log scale (C, D) of each of the four inflammatory markers 3 h (A, C) and 24 h (B, D) after instillation. 24 h figure additionally includes data from 18 μg CB. Figure legends and correlation coefficients (r²) at 3 h are: Squares, Mcp-1 = 1.00; diamonds, Mip-2, 0.85; cross, neutrophils = 0.94; triangles, Il-6 = 0.84; At 24 h r²-values were below 0.60 for all four datasets.
