title: [Enzymes participating in the formation of ammonia in various experimental liver diseases].
abstract: The activity of adenosine desaminase AMP-desaminase and glutaminase was studied in blood serum and the liver tissue at the normal state and with acute, subacute experimental affection of the liver as well as with the CCl4-induced liver cirrhosis and obturation jaundice in different periods. It is shown that the degree and trend of changes in the enzyme activity in the affected liver depend on the character and duration of the affecting agents action. The acute and subacute affection of the liver and one-day obturation jaundice are accompanied by a decrease in the activity of all the studied enzymes in the liver tissue. With cirrhosis induced by a multiple administration of CCl4 for three months or with a month obturation jaundice the activity of glutaminase in the liver tissue lowers and that of adenosine desaminase and AMP-desaminase increased sharply. In blood serum the activity of adenosine desaminase and AMP-desaminase increases more considerably with acute affection and cirrhosis, especially with billar one.
