title: [Correlations between the diminished secretion of export proteins from the liver and the plasmatic activity of liver cell enzymes (author's transl)].
abstract: For the evaluation of certain differences in the diminution of export proteins of the liver we examined some exactly defined groups of liver diseases with the aim of further differentiation of the pathogenetic mechanisms. We measured the activity of glutamate-oxalacetate transaminase, glutamate-pyruvate transaminase, glutamate dehydrogenase, lactate dehydrogenase, alkaline phosphatase, cholinesterase and lecithin-cholesterol acyltransferase, the Quick value, the coagulation factors I, II, V, VII, VIII, IX and X. Clotting factors were determined by a Schnitger-Gross Coagulometer. Prothrombin, antithrombin III, plasminogen, factor VIII associated antigen and activated factor XIII were measured by immunoelectrophoresis according to Laurell. Lipoprotein electrophoresis in agarose gel was performed to evaluate changes in lecithin-cholesterol acyltransferase activity. Except of the rising diminution of export proteins in the course of liver disease from acute hepatitis to cirrhosis we found also specific changes of the patterns of the plasma specific enzymes. These proteins were diminished dependent on their half life time and the inflammatory activity--measured as the height of the transaminases. Lecithin cholesterol acyltransferase and factor VIII did not participate in the general diminution of the most export proteins; some details were found to explain this differing behaviour. Results are critically discussed with regard to new aspects in the biochemistry of the damaged liver cell.
