Presence of inflammation in serum and liver. Levels of C-X-C motif chemokine ligand 1 (CXCL-1) in serum (A) and liver (B), levels of monocyte chemoattractant protein-1 (MCP-1) in serum (C) and liver (D), level of interleukin-6 (IL-6) (E) and tumor necrosis factor α (TNF-α) (F) in the liver were detected by commercial ELISA kits. Data are expressed in mean ± standard error of mean (SEM) (n = 6 each group). ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001 for one-way ANOVA test with post hoc analysis (Bonferroni) among different groups; ^##p < 0.01 for student's t test between two groups.
