Figure 1 Serum amylase, pancreatic isoamylase (P-Iso), and lipase concentrations during 5 consecutive days in 2 subjects. Trypsin concentrations are also seen in 1 of the 2. Enzymes are abnormally elevated, albeit with wide fluctuations, for all 5 days of the study. Values are shown as multiples of the upper normal limit (broken line).

Figure 2 Serum amylase, pancreatic isoamylase (P-Iso), and lipase concentrations during 5 consecutive days in 2 other subjects. Trypsin concentrations are also seen in 1 of the 2. Enzymes are abnormally elevated for only 1 day in 1 subject and for 2 days in the other. Values are shown as multiples of the upper normal limit (broken line).
