Abstract
The effect of experimental hypoxia on blood glutamine, glutamate, urea, ammonia, allantoin, hypoxanthine, xanthine, urate, orotate and lactate concentrations and on PO2, PCO2 and, pH m term delivered newborn rats during the first 4 h after delivery were studied. Hypoxia increased blood glutamine, glutamate, allantoin and ‘xanthines’ (hypoxanthine + xanthine + uric acid) concentrations but decreased blood urea and ammonia concentrations. These results suggest that hypoxia inhibited ureogenesis by decreasing the ammonia available for urea synthesis.
