[Enzyme activity in the regeneration process after partial hepatectomy of normal liver and that injured with deoxycholic acid].

After partial hepatoectomy of the rat normal liver a maximum three-fold increase in the activity of alkaline phosphatase is observed in the blood serum, on the second-third day, and by the 14th day becomes almost normal; the activity of adenosine desaminase, AMP-aminohydrolase and 5'-nucleotidase becomes 30-60% as high for one-two days. The activity of the alkaline phosphatase in the liver becomes four times as high and reaches normalcy by the sixth day. The activity of adenosine desaminase and AMP-aminohydrolase increases to a less extent for a fortnight. The activity of 5'-nucleotidase decreases in the first day, then rises and a fortnight later becomes normal. After partial hepatoectomy of the liver injured with deoxicholic acid the activity of all the enzymes in blood serum anr a longer period of time; in the 5'-nucleotidase activity there is no initial drop and its earlier subsequent increase is observed.
