[Characteristics of pancreatic basal secretion in the dog]

A method is described for the simultaneous evaluation of the pancreatic, the biliary and the gastric secretion in long-term experiments. Under these conditions, the pancreatic basal secretion is characterized. The pancreatic basal secretion is a very variable reference value that is influenced by endogenous stimuli. The upper threshold value for the secretion rate was 2.2 ml/15 min. Under the influence of spontaneous biliary secretion, the protein concentration amounts to a characteristic value of relatively unimportant variance. If the pancreatic basal secretion is used as a reference value, the spontaneous secretions of the biliary ducts (gastrin release from the duodenum?) and of the stomach (secretin release from the duodenum) and be taken into account. A further disturbing factor interfering with both the pancreatic and the gastric basal secretion is to be neglected.
