Notes:
Sweet smelt Plecoglossus altivelis (Temminck et Schlegel) were fed with diets containing 0.01% or 1% α-tocopherol for 14 weeks to investigate whether an excess dose of α-tocopherol effected several biological functions of fish. The different concentrations of α-tocopherol in fish diets did not affect fish body weight or length, or fatty acid composition of fish blood. However, the accumulation of hydroperoxides in plasma and erythrocytes of fish fed 1% α-tocopherol was significantly higher than those of fish fed 0.01% α-tocopherol. The osmotic fragility of fish erythrocytes showed the opposite result. These results suggest that an excess dose of dietary α-tocopherol promoted lipid peroxidation, increasing the accumulation of hydroperoxides in fish blood but reducing the erythrocyte osmotic fragility.
