[Radioimmunoassay in the evaluation of pancreas function in chronic pancreatitis].

Insular apparatus function in primary chronic and reactive pancreatitis associated with hepatobiliary pathology was studied in 178 patients by radioimmunoassay. The authors showed typical changes of insulin and C-peptide concentration in the presence of an i.v. glucose tolerance test that make it possible to differentiate in combination with the trypsin concentration in the serum primary and reactive pancreatitis as well as exacerbation and remission stages of the disease.
