Measurement of TNF-α, IL-6, and KC levels in BALF by ELISA. BALF samples were collected as described in Figure 2. ST reduced the level of cytokines (TNF-α, IL-6) and chemokine (KC) when measured with a quantitative sandwich enzyme-linked immunoassay (ELISA). a) TNF-α, b) IL-6, c) KC. n = 5 in all groups. Data are shown as the mean ± S.E.M. Statistical analyses were conducted by one-way ANOVA followed by Newman-Keuls Multiple Comparison test; ###p < 0.001, #p < 0.05 vs. AIR, ***p < 0.001, **p < 0.01, *p < 0.05 vs. CS.
