[Stomach ulcer as a problem of energy balance: design of a cellular automatic simulation of disorders of blood flow distribution in the stomach wall].
A cellular automaton is described, which allows a simple simulation of patterns of gastric blood flow distribution. Effects of redistribution, which can be simulated on the basis of the energy requirements of acid secretion and the morphology of the gastric vascular bed, are isomorph to form and site of gastric ulcer in man. Special forms of the 'peptic' lesion as linear ulcers or 'peptic' stenoses of the oesophagus are consistent with the theory of a submucous steal-phenomenon.
