Developmental neurotoxicity of low-dose di-n-butyl phthalate (DBP) to rats was studied. Pregnant rats were orally given DBP at doses less than 1.0 mg/kg/day during gestation period. The body weight of all dams and their offspring as well as the offspring's motor function showed no significant adverse effect. At 21 weeks, behaviors of male rats were examined by placing into a test cage. The rats born from dams exposed to 10 microg DBP/kg/day exhibited a significant decrease of grooming. This indicates low-dose DBP adversely affects emotional stability in a novel environment.
研究了低剂量邻苯二甲酸二正丁酯(DBP)对大鼠的发育神经毒性。在妊娠期,给怀孕大鼠口服低于1.0毫克/千克/天剂量的DBP。所有母鼠及其后代的体重以及后代的运动功能均未显示出明显的不良影响。在21周时,将雄性大鼠放入测试笼中检查其行为。出生于暴露于10微克DBP/千克/天剂量母鼠的大鼠出现明显的理毛行为减少。这表明低剂量DBP会对新环境中的情绪稳定性产生不利影响。
