The patriarch of experimental pancreas research is REIGNIER DE
GRAAF (1641-1673). He carried out the first experiments with dogs
in order to ob tain fistular secretion (1664). But only few years
later, the just arisen interest in the physiology of the pancreas
was severely set back by remarks of CONRAD BRUNNER. In 1682,
BRUNNER expressed his belief that on the basis of experi ments he
had carried out the pancreas was a vitally unimportant organ. He
overlooked that after ligation of the main duct (discovered in the
turkey by HOFMAN in 1641 and in a human cadaver by WIRSUNG in
1642), in the dog an accessory duct (described by SANTORINI in
1724) usually maintains an adequate flow of secretion. EBERLE in
his monograph (1834) confirmed the emulsifying capacity of the
pancreatic juice which had already been suggested by SYLVIUS (FRAN
CISCUS DE LE BOE, 1614-1672) and he dealt with the essential
enzymatic functions of the pancreatic juice such as amylolysis,
lipolysis and proteolysis. Since HEIDENHAIN (1875), we know that
for example trypsin (largely isolated by KUHNE in 1867) is situated
in the acinar epithelial cells as zymogen in inactive form; it is
thought that the action of "acid" on the glandular tissue is needed
for inducing the "enzymatic activity." According to what we know
now about the central role of acidosis in the activation of zymogen
this topic is, of course, of topical interest."
