Fig. 2From: Oxidative-antioxidative status and hepatic and renal factors following melatonin administration in castrated and intact dogsChanges in the antioxidant enzymes (SOD, GPX, and CAT) and malondialdehyde (MDA) concentrations (Mean ± SEM) in the control, melatonin, castrated, and castrated+melatonin groups (n = 5 in each group) during the one-month study. The mean concentrations were compared using one-way and two-way repeated-measures analysis of variance (ANOVA) and Tukey’s multiple comparisons tests (CAT: catalase; GPX: Glutathione peroxidase; SOD: superoxide dismutase; MDA: malondialdehyde)Back to article page
