Brewers’ rice modulates oxidative stress in azoxymethane-mediated colon carcinogenesis in rats

Table 3 Colon superoxide dismutase, malondialdehyde, and nitric oxide levels in azoxymethane-induced colon cancer after twenty weeks treatment

Group	SOD (U/mg of protein)	MDA (nmol/g of protein)	NO (μmol/mg of protein)
Normal	60.93 ± 5.23a	5.36 ± 0.23a	414.64 ± 11.59a
AOM alone	43.43 ± 2.96	18.01 ± 1.43	798.46 ± 30.45
AOM + 10% (w/w) of brewers’ rice	43.85 ± 6.32	17.34 ± 3.16	622.70 ± 15.62a
AOM + 20% (w/w) of brewers’ rice	61.71 ± 2.36a	14.24 ± 0.58a	533.40 ± 40.43a
AOM + 40% (w/w) of brewers’ rice	61.29 ± 4.32a	8.14 ± 1.42a	619.35 ± 15.04a

Each value expressed as mean ± SD (n = 3). ^aP < 0.05 vs AOM alone, Tukey’s test. MDA: Malondialdehyde; NO: Nitric oxide; SOD: Superoxide dismutase.
