title: Effects of nivalenol on the bone marrow in mice.
abstract: In order to investigate the toxic effects of nivalenol, one of the trichothecene mycotoxins, we performed a short-term feeding trial for 24 days using feed supplemented with rice artificially molded with nivalenol producing fungus, Fusarium nivale Fn 2B, in female C57BL/6CrSlc SPF mice. A significant erythropenia and slight leukopenia were observed in the 30 ppm group, but no marked changes were observed in other hematological parameters, feed consumption, body weight gain, or weights of the liver, spleen, and thymus. Ultrastructural studies also revealed polyribosomal breakdowns of the bone marrow cells in the 30 ppm group.
