The Neutral Carbohydrate Chains of Gastric and Duodenal Mucosubstances
- 144 Downloads
A complete stomach and duodenum were obtained at autopsy from an individual with no history of gastroduodenal disease, and divided into body-fundus, antrum, upper duodenum (approximating to the first and second segments), and lower duodenum (third and fourth segments). The gastroduodenal mucosa was histologically normal. The mucosa was dissected from each specimen, and preparations of mucuous glyco-polypeptides were obtained by a procedure of pronase digestion and column chromatography.
