title: [Dye-marking and hydrogen clearance in demonstrating acute ischemic myocardial areas].
abstract: After acute myocardial infarction (produced by ligation in the dog), the authors marked the borders of infarction with disulphine blue or methylene blue and determined, by means of hydrogen clearance, the blood supply in the centre and at the margin of infarction as well as at different distances from the latter. At the margin of infarction, the value for blood flow amounted to almost 17% of the value measured prior to ligation. Only at a distance of 1 cm. from the visible margin of infarction, 50 to 80% of the initial value were obtained. The extension of the area of infarction beyond the marked visible margin must be considered in surgical interventions.
