Peptic ulceration experimental production

Code concluded that the experiments incriminated gastric juice as the factor in the production of peptic ulcer, but only later did he realize that he had produced the experimental equivalent of the Zollinger-Ellison syndrome. Frank Mann was pleased by the results, for up to that time he had not been able to produce experimental ulcers in the duodenum as the result of action of the animal s own gastric juice.
