Table 1 Mean ± SEM concentrations of antioxidant enzymes and malondialdehyde (MDA) in the melatonin, castrated, control, and castrated and melatonin treated (Cast+Mel) groups during the one-month study. Melatonin was administrated to the melatonin and Cast+Mel groups for 1 month

From: Oxidative-antioxidative status and hepatic and renal factors following melatonin administration in castrated and intact dogs
