| Abstract: | Abstract— Rats have been subjected to portocaval anastomosis and the ammonium ion in plasma and the glutamate and glutamine levels in plasma, red cells and brain have been estimated up to 6 weeks after operation. The glutamine, but not the glutamate, levels in brain were consistently raised, being about 2.5 times greater than normal and the level can be correlated with the level of plasma ammonium ion. Consideration is given to the possibility that the glutamine may be in the greatly enlarged neuroglial compartment in this abnormal metabolic state. |
