Functional teratogens of the rat kidney: II. Nitrofen and ethylenethiourea
Nitrofen and ethylenethiourea (ETU), agents known to prenatally induce hydronephrosis in rats, were assessed for their effects on postnatal renal functional maturation. Both were given by gavage to pregnant Sprague-Dawley rats on Gestation Day 11. Nitrofen was given at concentrations of 50 or 100 mg...

description | Nitrofen and ethylenethiourea (ETU), agents known to prenatally induce hydronephrosis in rats, were assessed for their effects on postnatal renal functional maturation. Both were given by gavage to pregnant Sprague-Dawley rats on Gestation Day 11. Nitrofen was given at concentrations of 50 or 100 mg/kg, and ETU at 20, 40, or 60 mg/kg. Renal function was examined in the offspring from birth until after weaning, the period of renal functional maturation in the rat. Maximal urine concentrating ability was measured after DDAVP (desmopressin acetate, a vasopressin analog) challenge or water deprivation. Proximal tubule transport was measured in renal cortical slices. Various urinary parameters were measured. Both prenatal nitrofen and ETU exposure caused a large number of neonatal deaths at the high dose, and hydronephrosis was observed. The severity of the lesion increased with age. Hydronephrotic animals were deficient in urine concentrating ability, which became more pronounced after weaning. A few other urinary parameters were altered, but cortical function appeared to be unaffected. Rats prenatally exposed to nitrofen, but with apparently normal kidneys, were significantly compromised in their ability to produce a concentrated urine in response to DDAVP challenge, on Postnatal Days (PDs) 6 and 14. By PD 30, they were not different from controls in urine concentrating response. Rats prenatally exposed to the higher doses of ETU, but with grossly normal kidneys, had significantly decreased plasma clearances of certain electrolytes early in life, but by PD 27, they were not different from controls. Proximal tubule transport of PAH was increased on PD 7 in ETU-exposed pups, but this effect did not persist. |
