Figure 7.

The effects of glycyrrhizin on the expressions of TLR-4 (A) and CXCR4 (B) in the lung tissue of the lipopolysaccharide-induced acute lung injury model. The lung injury score was significantly higher in the LPS group than in the control group, while it was significantly lower in the LPS plus GR group than in the LPS group (C). *P<0.001, control group vs. LPS group; ^#P<0.001 and ^##P<0.05, LPS group vs. LPS + GR group. Con, control group; LPS, lipopolysaccharide-induced acute lung injury group; LPS + GR, glycyrrhizin administration group; TLR-4, Toll-like receptor 4; CXCR4, C-X-C chemokine receptor type 4.
