title: Amino acid disturbances in experimental hepatic coma rats.
abstract: In our previous paper (1), we discussed the in-vitro adsorption spectrum of plasma amino acids by coated charcoal hemoperfusion. We now describe the general amino acid disturbances in plasma, CSF and cerebrum in the galactosamine induced hepatic coma model in rats. All aromatic amino acids (AAA) increased significantly in the three compartments studied. Branched chain amino acids (BCAA) were either elevated to a much lesser extent or remained unchanged. The molar ratio of BCAA:AAA was consequently reduced. This is similar to findings in fulminant hepatic failure in human and other animal models. Most of the 20 amino acids analyzed were increased significantly in the plasma. Increases of amino acids were minimal in the brain tissue studied, i.e. the cerebrum.
