    Abstract:
    Levels of free amino acids were analysed in plasma and muscle tissue of nine patients with acute hemorrhagic necrotising pancreatitis and compared with date from healthy volunteers. In the patient group the concentrations of threonine, serine, glutamine (p less than 0.001) and tyrosine (p less than 0.01) in plasma were found to be significantly lower than in the volunteers group, while increased plasma levels were found for 3-met-histidine (p less than 0.05). In muscle tissue the cytoplasmatic levels of glutamate, glutamine and histidine (p less than 0.001) and also of lysine, ornithine and arginine (p less than 0.,01) showed decreased concentrations. However tyrosine and phenylalanine had increased intracellular concentrations (p less than 0.05). It is concluded that (1) the patients in this study had a severely disturbed amino acid metabolism with extremely reduced levels of free glutamine in muscle tissue and (2) that the disturbed amino acid metabolism results from an acute catabolic situation of the patients, in which the reduced levels of free amino acids may indicate an impaired nutritional state.
