The development and validation of a radioimmunoassay that detects release of secretin in plasma in response to low doses of secretagogues [intraduodenal HCl (0.033 meq/min); intraduodenal sodium oleate (0.04 mmol/min)] or an oral mixed meal in conscious dogs is described. Plasma secretin levels increased significantly (P<0.05) in response to an oral mixed(More)
We have examined the release of gastrin and somatostatin from the isolated perfused stomach of rats of three different age groups (4 months, 12 months, and 24 months old) in response to bombesin and carbachol. The basal release of gastrin was diminished in 24-month-old rats. Basal somatostatin release showed an age-related decrease. Bombesin (10−10 and 10−9(More)
