ABSTRACT
Objective To observe the antioxidant activities of whey protein peptides (WPP) in aged mice.Method The subacute aged model mice were made by neck back subcutaneous injection of D-galactose every day.Compared with VE as positive control,the mice were given three different doses of WPP,100,200,400 mg/(kg bw?d) respectively,the effect of WPP on the content of catalase (CAT),malondialdehyde (MDA),superoxide dismutase (SOD),glutathione peroxidase (GSH-PX)in serum,liver and brain were observed after 45 d.Results The CAT,SOD and GSH-PX activities in aged model group were significantly decreased,but MDA was significantly increased as compared to normal mice.While in the aged mice treated with WPP 200 and 400 mg/(kg bw?d),the activity of CAT,SOD and GSH-PX were significantly increased and the content of MDA significantly decreased as compared to aged mice.Conclusion WPP shows dose-dependant antioxidant effect in aged mice.
