title: Persistent influence of neonatal 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) treatment on glucocorticoid receptors and on the microsomal enzyme system.
abstract: Neonatal treatment with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) accounted for a considerable decrease in the number of thymic glucocorticoid receptors in both male and female rats, as assessed at 6 weeks of age. TCDD also gave rise to a marked and prolonged increase in microsomal enzyme activity in the female rats but had practically no such effect on the males. These experimental observations attract attention on to the lasting microsomal inducer effect of the herbicide contaminant dioxin which damages foreign receptors and substantiate the chemical imprinting potential of aromatic hydrocarbons.
