Effects of dietary Res treatment on serum lipid levels and oxidative stress conditions. (A, B, C, D) Serum levels of TG, TC, LDL-C and HDL-C, which represent serum lipid levels were measured before the Res treatment and after a 12-wk study period. (E, F, G). Serum levels of FFA, SOD and MDA representing oxidative stress conditions were measured as well. Data are shown as the mean ± S.D. #P < 0.05 and ##P < 0.01 vs. C57BL/6 J. *P < 0.05 and **P < 0.01 vs. KKAy control, n = 10.
