Abstract: | Lipid peroxidation, protein oxidant and antioxidant status of muscle, intestine and hepatopancreas in juvenile Jian carp (Cyprinus carpio var. Jian) fed graded levels of myo-inositol (MI) (163.5, 232.7, 384.2, 535.8, 687.3, 838.8 and 990.3 mg/kg diet) for 60 days were investigated. Total tissue malondialdehyde (MDA) and protein carbonyl (PC) content showed a downward trend to a point (P < 0.05). Conversely, total tissue anti-hydroxyl radical (AHR), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx), glutathione reducase (GR) activities and glutathione (GSH) content were generally higher in MI-supplemented diets than MI-unsupplemented diet (P < 0.05). Muscle and intestinal superoxide dismutase (SOD), and intestinal anti-superoxide anion (ASA) were increased by MI supplementation (P < 0.05), whereas these parameters in the other tissue showed no alterations (P > 0.05). These results indicated that antioxidant status was improved, and lipid peroxidation and protein oxidant were depressed in muscle, intestine and hepatopancreas by MI. |
