title: Effect of vitamin E on IgE antibody formation in mice.
abstract: Effect of vitamin E (alpha-tocopheryl acetate and alpha-tocopheryl nicotinate) on IgE antibody formation in mice was investgiated . Female BALB/c mice were immunized with dinitrophenylated ascaris protein (DNP-As) and aluminium hydroxide gel (alum). Supplementation of vitamin E in diets or oral administration of vitamin E mixed with sesame oil resulted in a suppression of IgE antibody formation. On the contrary to IgE antibody formation, IgM or IgG (hemagglutinin; HA) formation was significantly enhanced. These results indicate that vitamin E is capable of suppressing IgE antibody formation and enhancing non-IgE antibody formation.
