title: Bisalbumin (fast and slow type) induced by human pancreatic juice.
abstract: To clarify the relationship of pancreatic juice to bisalbumin, we examined the effects of human pancreatic juice and pancreatic proteolytic enzymes on human serum albumin. Electrophoresis showed that a fast-moving band and an increased component of alpha 1-globulin appeared after incubation of serum with pancreatic juice. These components were shown to be albumins by immunofixation and immunoelectrophoresis. The alpha 1-component increased after incubation of serum with trypsin, and was confirmed as a slow-type albumin by immunoelectrophoresis. Fast-type albumin was observed after incubation of serum with chymotrypsin, and carboxypeptidases A and B. In all patients with pancreatic ascites, the fast- and slow-type albumins were seen in serum and ascitic fluid. Bisalbumins appeared in ascites at higher concentrations than in serum, and disappeared after surgical or conservative treatment. The results demonstrate that human pancreatic juice can produce fast- and slow-type albumins by proteolytic enzymes, and they are seen in patients with pancreatic ascites.
