title: Role of ischaemia in the initiation of peptic ulcer.
abstract: Study of intramural vascular pathways to the human gastroduodenal mucosa shows that some persons have patches of mucosa supplied by end arteries. These patches occur only in the ulcer-bearing areas. It is suggested how this may contribute to the initiation of peptic ulceration and explain some of its features.
