241只小鼠分别饮用不同浓度的 T-2毒素水溶液7～18个月。病理形态学观察结果表明,T-2毒素有诱发小鼠发生肿瘤的作用。饮水中含T-2毒素0.05mg/kg 可诱发雌性小鼠乳腺癌,发生率达35%,而对照小鼠仅为4%。饮水中含 T-2毒素0.1mg/kg,可诱发雌性小鼠黄体瘤,发生率达10%,而对照小鼠为0%。 241 mice were given different concentrations of T-2 aqueous toxin for 7 to 18 months. Pathological observations showed that T-2 toxin induces tumors in mice. Drinking water containing T-2 toxin 0.05mg/kg can induce breast cancer in female mice with an incidence of 35% compared with 4% in control mice. Drinking water containing T-2 toxin 0.1mg/kg, can induce female mice with luteoma, the incidence rate of 10%, while the control mice were 0%.
