title: Immunoreactive gastrin concentrations in gastrointestinal tissues of sheep.
abstract: Radioimmunoassay of gastrin in gastrointestinal tissues of lambs and adult sheep showed highest concentrations (796 to 11,156 pmol g-1 mucosa) in the antral region of the abomasum. The next highest concentrations of gastrin were in the proximal duodenal mucosa (16 to 518 pmol g-1). Gastrin was undetectable or present in lower concentrations in caudal regions of the duodenum (less than 11 X 5 pmol g-1), the pancreas and in the body of the stomach. It is concluded that the distribution of gastrin secreting cells in sheep is similar to that in other animals.
