Hello friends

I am watching some article entitle antioxidant against algal bloom. In this articles maximizes antioxidant were decrease SOD , CAT and GPx and increase Vit-E, Vit-C and GSH. But in animal model the enzymatic antioxidant such as SOD , CAT and GPx were increased and non- enzymatic antioxidant such as Vit-E, Vit-C and GSH were decreased. How is it possible? I request you kindly clear my doubt please.
