[Pancreatic enzyme activity in early phases of acute experimental pancreatitis in rats].

Experiments were performed on laboratory rats with acute pancreatitis caused by local freezing the pancreas with chlorethyl. An active action of enzymes alpha-amilase, lipase, phospholipase A2, was revealed. During the first hours, an increase in action of all three enzymes, particularly that of phospholipase A2, was found.
