| Popis: | Pure pancreatic juice was collected from 8 subjects by endoscopic retrograde cannulation of the papilla. Samples were collected at 1 minute intervals for 20 minutes after rapid intravenous injection of secretin (Eisai, 1u/kg) and for 10 to 15 minutes after rapid intravenous injection of CCK-PZ (1 U/kg). Three hydrolases (amylase, chymotrypsinogen and lipase) showed nonparallel secretory pattern. Lipase was proportionally more stimulated than chymotrypsinogen and chymotrypsinogen was more stimulated than amylase by CCK-PZ stimulation. However, in one subject the secretion of three hydrolases was parallel and in another subject lipase and chymotrypsinogen showed parallelism. Samples collected at "wash out" period showed quite high enzyme and protein concentration with specific activity and enzyme ratio not different from those of samples collected at peak period of CCK-PZ stimulation. Normal ranges were estimated in peak flow rate per minute, peak enzyme concentration, specific activity of enzymes, maximal enzyme output per minute and maximal bicarbonate concentration. |
