title: Concentrations of free amino acids in plasma, erythrocytes and cerebrospinal fluid in coma.
abstract: The concentrations of free amino acids were measured in plasma and erythrocytes in 15 patients, and in cerebrospinal fluid in eight patients, who were in coma. Although there was a variety of causes of coma, there seemed to be a characteristic pattern of the concentrations of amino acids for coma, and the plasma/cerebrospinal fluid ratios also showed constant patterns.
