Fig 3. n-butanol exposure and upper airway inflammatory mediators.

Fig 3

Data are shown as median level with interquartile range of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), Interleukin-4 (IL-4) and IL-1β (in pg analyte/mg total protein) measured in the upper airway epithelial lining fluid from the MCS group and from the control group at the three time points (TP); TP1 at time zero, TP2 at the end of the n-butanol exposure and TP3 4 hours post exposure. Asterisks refer to significant differences (P ≤ 0.05) in analyte concentrations between TP1, TP2 and TP3 within either the MCS or the control group.
