Effect of HFD and BM on brain anti-oxidative enzymes. Enzymatic activities of MnSOD (A), CuZnSOD (B), catalase (C), GPX (D), ratios of CAT/SOD (E) and GPx/SOD (F) as well as GSH (E) levels in brains of mice fed HFD with and without BM. Values represent the mean ± SE (n = 4). Each sample was analyzed in duplicate. a,b,cMean values with common letters do not differ (p < 0·05).
