[A improved demonstration of ischemic myocard injuries with a combined method for evidence of the succine dehydrogenase and the acridin-fluorchrome-technique (MS-AO-technique) (author's transl)].

A method is described for combined enzyme histochemical and fluorescence microscopical investigation of ischemic injuries. This new method allows to distinguish between 1 reversible and 3 irreversible zones at the experimental ligature infarct of 48 h duration. Heterolysis is discussed as reason for the 3 outer zones and autolytic processes for the central area.
