co-treatment of mice with a 25 mg/kg dose of all the commercial aroclors and with a 50 mg/kg dose of a reconstituted pcb mixture ( resembling a pcb extract from human milk ) with tcdd ( 3.7 nmol/kg ) showed that , with the exception of aroclor 1232 , all of the commercial pcbs and the reconstituted pcb mixture significantly antagonized the tcdd-mediated inhibition of the splenic plaque-forming cell response in c57bl/6 mice .
