Abstract
In order to improve the diagnostic evaluation of pancreatic exocrine function, /sup 75/Se-activity in the duodenal aspirate of twenty control subjects and 131 subjects with pancertic and/or gastrointestinal disease was measured following intravenous injection of /sup 75/Se-selenomethionine. Radioactivity in the duodenal aspirate of the control subjects remained low until 80 min. It then rose rapidly and reached a plateau at 115 min. In contrast, radioactivity in the subjects with pancreatic diseases remained low, or rose only slowly throughout the period of collection. Radioactivity of the protein fraction (TCA-precipitable) in the 80 to 130 min. duodenal aspirates showed good separation between controls and subjects with pancreatic disease. The incidence of abnormalities of TCA-precipitable radioactivity in the 80 to 130 min. duodenal aspirates was significantly higher than that of the conventional PS-test parameters in groups with various pancreatic diseases. All of the subjects having an abnormal maximal ratio of TCA-precipitable radioactivity to protein (representing pancreatic enzyme synthesis) showed an abnormal distribution in output of TCA-precipitable radioactivity in 80 to 130 min. collection (representing both enzyme synthesis and excretion). On the other hand, subjects with an abnormal output of TCA-precipitable radioactivity in 80 to 130 min. could be separated into those with normal
