[Change in proteolytic enzymatic activity in the blood serum in children with chronic diseases of the digestive organs]. / Izmenenie aktivnosti nekotorykh proteoliticheskikh fermentov v syvorotke krovi u detei s khronicheskimi zabolevaniiami organov pishchevareniia.

The activity of trypsin, common trypsin inhibitor and elastase was evaluated in the blood serum of children with chronic diseases of the digestive organs. The activity of trypsin and its inhibitor was shown to be elevated in most children with both concomitant pancreatitis and without it. Increased activity of the trypsin inhibitor reflects a positive compensatory response of the body to excess trypsin supply to the blood. The activity of serum elastase rises only with exacerbation of chronic pancreatitis.
