EPO downregulated the expression and concentration of IL-1β and IL-18 in LPS-induced ALI. EPO (5 U/g) was injected into the peritoneal cavity of mice after LPS (15 mg/kg) stimulation. The mice were sacrificed 8 h later, and the serum was obtained to measure the concentrations of IL-1β and IL-18 (A,D) by ELISA. The lung tissues were harvested to measure the concentrations of IL-1β and IL-18 (B,E) by ELISA, and the mRNA expression levels of pro-IL-1β and pro-IL-18 (C,F) were measured by QPCR. The data are presented as the mean ± SD. The differences among groups were assessed by one-way ANOVA and the post hoc test (Turkey method) was applied to investigate the differences one by one. n = 8 per group.
