Abstract

Di-n-butyl phthalate (DBP) is not only a plasticizer and solvent used in industry but also one of endocrine disruptor chemicals, a low level contaminant found in a wide variety of different media ranging from drinking water to infant formulae. To evaluate the cytotoxic function of NK cells in mice after contact with DBP, C57BL/6 female mice were orally dosed with di-n-butyl phthalate (250, 500, or 750 mg/kg body weight) for 14 consecutive days, and the control mice were administered vehicle (corn oil).(omitted)
