SUMMARY Changes in the concentrations of free amino acids in intracellular fluids and blood plasma were measured in rats treated with cortisol. Increasing age raised the concentrations of free amino acids in plasma, while in liver, with the exception of glycine and alanine, decreased concentrations were observed. Cortisol treatment reduced free amino acid levels in plasma and liver which suggested a progressive catabolism of body proteins and increased protein synthesis in the liver. In skeletal muscle of control rats the free amino acid concentrations increased during the experimental period. Cortisol increased the concentration of certain amino acids and decreased that of others due to an increased protein turnover in muscle.

Plasma and skeletal muscle free amino acids were measured in patients submitted to Hemodialysis (HD) or Continuous Ambulatory Peritoneal Dialysis (CAPD) in order to evaluate the effects of these different dialysis modalities on amino acid pools; the data were compared with those obtained in control subjects and in patients with advanced Chronic Renal Failure (CRF) not submitted to Regular Dialysis Treatment (RDT). Our findings show low intracellular concentrations of VAL, total Branched Chain Amino Acid (BCAA) and TYR in uremic patients treated with CAPD but not in those undergoing HD. The observed differences in muscle amino acid pattern could be well explained by a changed amino acid metabolism regulation in CAPD, possibly related to the sustained hyperinsulinism and to an increased rate of hepatic protein synthesis.
