title: Stimulation of uric acid production and depression of increase in plasma glutamine concentration by insulin in chickens infused with ammonia.
abstract: 1. A single intraportal injection of insulin remarkably stimulated uric acid production in the chicken infused with ammonium acetate and significantly depressed the increase in plasma glutamine concentration by the infusion of ammonia (P less than 0.01 at 20 min, P less than 0.05 at 40 min after the start of infusion). 2. The increases in ammonia concentration in the blood and kidney during the infusion of ammonia were not affected by the insulin pretreatment. 3. The depressive effect of insulin on the increase in plasma glutamine concentration by ammonia may be due to the acceleration by insulin of incorporation of glutamine into biosynthetic pathway of uric acid in the chicken.
