  • Title: Acid-base balance and plasma glutamine concentration in man.
    Author: Welbourne TC.
    Journal: Eur J Appl Physiol Occup Physiol; 1980; 45(2-3):185-8. PubMed ID: 6780339.
    Abstract:
    Plasma glutamine concentrations were measured in chronic metabolic acidosis and alkalosis in healthy male volunteers. Metabolic acidosis resulted in a significant drop in glutamine concentration while metabolic alkalosis significantly elevated glutamine levels. These changes in glutamine concentration correlated with both the bicarbonate and PCO2 levels. To determine whether bicarbonate or PCO2 levels influence the glutamine concentrations, respectively acidosis was induced by respiring 5% CO2. This resulted in a significant elevation in both PCO2 and glutamine while bicarbonate levels remained unchanged. The results demonstrate an effect of acid-base alterations upon plasma glutamine concentration mediated by PCO2.
