FIGURE 2.
Effects of EGCG on CINC-1 and MCP-1 levels in serum and BALF of rats. Both CINC-1 and MCP-1 levels in serum and BALF were significantly elevated in the rats exposed to CS for 56 days (A–D). EGCG attenuated CS-induced CINC-1 elevation in serum (A) and BALF (C) and reduced serum MCP-1 level (B) but not BALF MCP-1 level (D). The results are expressed as means ± SEM; n = 7 each group. SA group, water/sham air; CS group, water/cigarette smoke; EGCG/SA group, EGCG (50 mg/kg)/sham air; EGCG/CS, EGCG (50 mg/kg)/cigarette smoke. ∗p < 0.05 and ∗∗∗p < 0.001 for the comparison between CS and SA group, #p < 0.05 for the comparison between EGCG/CS and CS group.
