Skin tissue samples were collected at different time points indicated after E (filled bar), E/Dex (gray bar), or Sa (open bar) injection. Relative expression levels of messenger RNA (mRNA) of Cxcl1/KC (A), Cxcl2/Mip-2 (B), Il-1 β (C), Il-6 (D), and Opn (E) were analyzed as described in Materials and Methods. The values are mean ± SD (n = 6). *P < 0.05; **P < 0.01; ***P < 0.005.
