title: [Pathophysiological features of duodenal ulcers in elderly and senile patients].
abstract: The following conclusions can be drawn on the basis of the research results: 1. There is no reliable distinction between central hemodynamics and gastric blood flow indices in patients from different age groups. 2. The blood flow in the stomach wall is in a distinct direct proportion to acid production. 3. The gastric blood flow is doubled in most patients with acid peptic ulcers, as compared with the norm. 4. The role of the ischemic factor in the development of duodenal ulcers is not pronounced in elderly patients.
