Data are presented as mean±sd. TDI: toluene diisocyanate; BALF: bronchoalveolar lavage fluid; IFN: interferon; IL: interleukin. **: p<0.01, compared with the control group. No significant differences were observed between the TDI group and the TDI+prednisone group or between the TDI group and the TDI+fluticasone propionate group.
