ABSTRACT
The splanchnic net fluxes of ammonia, urea and glutamine were measured during and after feeding. Hepatic glutamine synthetase activity was also estimated. Ammonia load to and extraction by the liver increased following feeding but returned to baseline within seven hours. During feeding, hepatic glutamine production increased and was complemented by an increase in glutamine extraction when the ammonia load had returned to baseline. Hepatic glutamine synthetase activity followed an inverse trend.
