All data were presented as mean ± SD of eight replications. Different superscripts on the same line showed a significant difference (p < 0.05) A: faeces with all mice given standard diet, B: faeces with the control group given standard diet and BRB given black rice bran modified diet, C: 8 weeks after AOM induction, D: 16 weeks after AOM induction, E: Cecum contents were taken after euthanasia.
