Abstract
We studied the effect on ureagenesis of a single dose of N-carbamylglutamate (NCG) in healthy young adults who received a constant infusion (300 min) of NaH13CO3. Isotope ratio-mass spectrometry was used to measure the appearance of label in [13C]urea. At 90 min after initiating the H13CO3- infusion each subject took a single dose of NCG (50 mg/kg). In 5/6 studies the administration of NCG increased the formation of [13C]urea. Treatment with NCG significantly diminished the concentration of blood alanine, but not that of glutamine or arginine. The blood glucose concentration was unaffected by NCG administration. No untoward side effects were observed. The data indicate that treatment with NCG stimulates ureagenesis and could be useful in clinical settings of acute hyperammonemia of various etiologies.
