Effect of white-fleshed peach extracts (WFPE) on chronic nicotine-induced oxidative stress in mouse tissues. After mice were administrated nicotine (5 mg/kg body weight [BW]) and/or WFPE (250 mg/kg BW or 500 mg/kg BW) for 5 weeks, liver and kidney tissues were collected and homogenized. (A) The level of malondialdehyde (MDA), as an indicator of lipid peroxidation, was measured in tissue homogenates. (B) Glutathione (GSH) content was evaluated by the reaction with Ellman’s reagent. (C) Among the enzymatic antioxidants, superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were analyzed by commercial available kits, respectively. Data are expressed as mean ± SEM (n = 6 per group). ^#P < 0.05 versus control group; *P < 0.05, **P < 0.01 versus nicotine group.
