Long-term of CS exposure does not enhance KC and MIP-2 in BAL fluid. Mice were exposed to CS (black bars) or to air (hatched bars) for 4, 12, 18 and 24 weeks and the levels of KC (A) and MIP-2 (B) in the BAL fluid were determined by ELISA. Data represent the average concentration per ml BAL fluid ± SEM from eight mice. The data set of Fig. 4A and 4B are shown for comparison. Statistical significance: * = p < 0.05; ** = p < 0.01; *** = p < 0.001 vs. before CS exposure at day 0.
