[Amino acid reserves of the blood in patients with schizophrenia and their correction in insulin coma].

Free amino acid content was measured in the blood serum in patients with permanently progressive paranoid schizophrenia under conventional insulin shock therapy. The influence of several amino acids (methionine, glutamic acid) preinjection on their base levels was also assessed. Metabolic response to the insulin coma was different in preinjected vs. control groups. Glutamine acid-preinjected patients displayed less pronounced shifts in amino acid reserves in the blood serum that smoothed the shock-related metabolic stress in these patients as related to conventional shock.
