Serum elastase 1 in chronic pancreatic disease.

Elastase 1 and immunoreactive trypsin were assessed by a RIA technique in the sera of 29 control subjects, 24 pancreatic cancer patients, 22 patients with chronic pancreatitis and 31 with extra-pancreatic diseases to ascertain and compare their usefulness in chronic pancreatic disease diagnosis. Increased levels of elastase 1 were detected in 60.9% of pancreatic cancer and in 61.

CEA and ferritin in chronic pancreatic disease: a comparative evaluation.

CEA and ferritin were determined in 90 subjects with the aim of comparing their value in the diagnosis of pancreatic malignancy. Ferritin was shown to be more sensitive than CEA in detecting pancreatic cancer patients (68.4% and 57.

CA 19-9 in the differential diagnosis between pancreatic cancer and chronic pancreatitis.

CA 19-9 serum concentration was determined by a immunoradiometric technique in 130 subjects to evaluate its role in differentiating pancreatic cancer from chronic pancreatitis. Two threshold values were chosen, 17 and 37 U/ml. With the former, sensitivity, specificity and diagnostic accuracy were 86.

Congenital short pancreas: a report of two cases.

We report two adult cases with partial agenesis of the pancreas. Their radiological features, including endoscopic retrograde pancreatography are demonstrated. The significance of developmental anomalies involving the pancreas is emphasised.

A kinetic assay for human urinary kallikrein determination.

A simple kinetic method for human urinary kallikrein determination is proposed. In this assay, the release of p-nitroaniline from the chromogenic substrate S-2266 at 37 degrees C and pH 8.2 is followed spectrophotometrically at 405 nm.
