Growth, accumulation and antioxidant response in juvenile carp (Cyprinus carpio) fed a selenium diet

HSe caused a significant Se accumulation in kidney and liver. Se enhanced the endogenous antioxidant capacity by increasing the glutathione content in HSe liver and kidney. Higher glutathione peroxidase activity was also recorded in both HSe tissues, while higher superoxide dismutase and catalase activities were noted only in HSe liver when compared with LSe carp. Although growth was not impaired in carp, oxidative stress indicators changed differently in both HSe tissues, suggesting that liver and kidney may have a dissimilar susceptibility to oxidative stress induced by the prooxidant factor of Se.
