Effect of purple rice husk extract on activities of xenobiotic metabolizing enzymes in the liver of AFB1-initiated rats. (a) phase I xenobiotic metabolizing enzymes, (b) phase II xenobiotic metabolizing enzymes. Values expressed as mean ± SD, n = 6. AFB1: aflatoxin B1; PRHE: purple rice husk extract; CYP: cytochrome P450; CPR: cytochrome P450 reductase; GST: glutathione S-transferase; UGT: UDP-glucuronyltransferase; NQO: NAD(P)H quinone oxidoreductase; HO: heme oxygenase. * Significant difference from control group (p < 0.05). # Significant difference from AFB1-treated group (p < 0.05)
