Measurement of nuclear transcription factor κB (NF-κB) in the lung tissue at 4 (A) and 24 (B) h of different gas exposure in control (white diagram) and lipopolysaccharides-treated (black) rats. Definition of the subgroups see Fig. 1 legends. NF-κB DNA-binding activity was measured with electrophoretic mobility shift assay. The values from densitometry of bands are means ± SD (n = 6) and expressed as arbitrary units. ++ p < 0.01 versus LPS-Air; ** p < 0.01 versus LPS-O; ## p < 0.01 versus corresponding C subgroup.
