| Abstract |
The separate and combined effects of prenatal protein deficiency (65 casein) and prenatal nitrofen exposure (12.5 mg/kg on gestational days 7-21) on renal morphology in the 21-day fetal and postnatal rat were examined. Maternal protein deprivation reduced maternal feed intake, feed efficiency, weight gain, and the number of litters produced at term. Numbers of nature glomeruli, creatinine clearance, water diuresis, and response to ADH, but not the hydropenic response, were lower in the PPD neonates. These changes in morphology and function suggest that prenatal protein deficiency delays renal development and possibly results in a decrease in glomerular clearance and in tubular response to a water load and to anti-diuretic hormone. Evaluation of postnatal renal function showed that prenatal nitrofen exposure depressed the ability to excrete excess water, the response to ADE, and urine concentrating ability. The functional deficits indicate tubular dysfunction, but little or no effect on glomerular function. Renal dysfunction may contribute to the increased mortality in PPD+nitrofen pups by reducing the ability to respond to stress, but the effects are not sufficiently marked to be considered the primary cause of death.
