CCL2 and peritonitis: Though both of DXM treatment group and combinational treatment group (DXM + MCL) decreased S. aureus induced MCP-1 level at 8 h compared with model group (S. aureus only) in lethal peritonitis model (Fig. 7), the level of MCP-1 in the combinational treatment group was maintained significantly higher than that of DXM treatment group (p = 0.0021) (Fig. 7c).
