Research Abstract

We for the first time described developmental abnormality with renal dysplasia induced in the kidney of rhesus monkey offspring exposed during prenatal and lactational period to TCDD. The renal lesions developed exclusively in offspring of dams exposed to relatively high dose (300ng/kg) of TCDD. We disclosed disturbed cox2-prostaglandin system as pathogenesis of the renal lesion.
