Thioglycollate-elicited macrophages were incubated with different concentrations of corylin for 1 h and then treated with 1 μg/mL LPS for 24 h. (A) The cell viability was determined by the MTT assay. (B) The level of NO in the cell culture supernatant was measured by the Griess reaction. (C,D) The levels of TNF-α and IL-6 in the cell culture supernatant were measured by ELISA. The data are presented as the means ± SD. Statistical significance was assessed by one-way ANOVA followed by Tukey post-hoc test and represented as follows: *p < 0.05 and **p < 0.01 vs. LPS alone.
