Part I: Immunological assays of clotting factors in the diagnosis of liver diseases. The immunological determination of Antithrombin III is a good measure of the capacity of the liver to synthesize plasma proteins. Antithrombin III concentration in serum correlated significantly with the prothrombin time and the activity of
cholinesterase
. The immunological determination of factor VIII related antigen seems to be important for the early recognition of the transition of an acute hepatitis into a chronic course. While following uncomplicated acute hepatitis the level of factor VIII related antigen is normal after 40 weeks, it remains high in cases which become chronic. Immunological assay of factor XIII seems to be not very useful in the diagnosis of liver diseases. Part II: Management of coagulation disturbances in liver diseases. Except cases of
hepatic coma
the hemostatic abnormalities in chronic liver diseases are rarely severe enough that correction is necessary. Prothrombin concentrates are considered by most of the discussants as unnecessary and potentially dangerous. Transfusion of platelets is only neccessary when the platelet count is below 40.000 and surgery is planned. It is uncertain whether patients with chronical liver disease and laboratory signs of DIC benefit from heparin therapy. Although laboratory tests may be improved, prognosis, especially in cases of acute oesophageal bleeding, seems to be not changed by this treatment.

The levels of C3,
cholinesterase
, albumin and prothrombin were determined in 46 patients (27 males and 19 females) - 26 with cirrhosis of the liver, 9 with acute hepatitis, 6 with chronic aggressive hepatitis, 1 with chronic persistent hepatitis and 4 with fatty liver. In all patients and, particularly in those with cirrhotic liver, it was shown that the normal or pathological level of serum C 3 is related both qualitatively and quantitatively to the normal or pathological levels of
cholinesterase
, albumin, and prothrombin. The percentage in which the levels of these four parameters were pathological was considerably higher in the cases with
hepatic coma
than in the cases without
hepatic coma
. The determination of the range of confidence for the 4 parameters showed that, in the patients with
hepatic coma
,
cholinesterase
reacted most sensitively to liver damage (0.5 - 0.94) followed by C3 and prothrombin (0.33 - 0.81). Also in the cases without
hepatic coma
,
cholinesterase
was the most sensitive indicator (0.05 - 0.29), followed by prothrombin (0.03 - 0.24), albumin and C3 (0.00-0.16).

Activities of choline acetyltransferase, acetylcholinesterase and
butyrylcholinesterase
were studied in the frontal cortex, temporal cortex, cerebellum and caudate nucleus obtained at autopsy from eight alcoholic cirrhotic patients who died in
hepatic coma
and from an equal number of age-matched subjects free from hepatic, neurological or psychiatric disorders. Activities of these enzymes were unaltered in the brains of cirrhotics compared to controls. Choline acetyltransferase and
cholinesterase
activities were also studied in the cerebral cortex, cerebellum, brain stem and striatum of rats four weeks following portacaval anastomosis and their sham-operated controls. Portacaval-shunting did not cause any statistically significant differences in the activities of choline acetyltransferase, acetyl or butyrylcholinesterases. These results argue against a presynaptic cholinergic lesion in human and experimental portal-systemic encephalopathy.
