Comparative Studies on the Hepatoprotective Effect of White and Coloured Rice Bran Oil against Acetaminophen-Induced Oxidative Stress in Mice through Antioxidant- and Xenobiotic-Metabolizing Systems

Figure 3

Effect of RBO administration on the activities of hepatic xenobiotic-metabolizing and antioxidant enzymes in mice. (a) APAP-metabolizing enzyme activities including CYP2E1, UGT, and GST. (b) Antioxidant enzyme activities including SOD, CAT, GPx, and GR. Results are expressed as (). significantly different from vehicle. # indicates significant difference from APAP. CYP2E1: cytochrome P450 2E1; UGT: UDP-glucuronosyltransferase; GST: glutathione S-transferase; SOD: superoxide dismutase; CAT: catalase; GPx: glutathione peroxidase; GR: glutathione reductase; APAP: acetaminophen; RBO: rice bran oil; WRBO: white rice bran oil; CRBO: coloured rice bran oil; NAC: -acetylcysteine.
