Effect of butyrate on the concentrations of TNF-α and IL-1β in BALF of mice with ALI. A. The concentrations of TNF-α in BALF at each time point after LPS administration and the effect of butyrate pretreatment. B. The concentrations of IL-1β in BALF at each time point after LPS administration and the effect of butyrate pretreatment. Data are expressed as mean ± SEM, *P < 0.05 vs. control and butyrate group; ^#P < 0.05 vs. LPS group.
