title: [Comparative enzyme-histochemical studies on normal myocardium, in cases of coronary insufficiency and myocardial infarction (author's transl)].
abstract: Comparative histochemical studies with Tetrazolium salt solutions were performed on 25 human and 3 canine hearts. After perfusion of whole hearts with Tetrazolium solutions extensive unstained areas were observed which proved to be artefacts, since they reacted positively after incubation of the heart-slices. The perfusion method of Lichtig, Feldman, Glagov and Wissler (1973) which was proposed for macroscopic and microscopic diagnosis of ischemic cardiac lesions was not found to be suitable for the identification of microcirculatory disturbances. The usual incubation method, however, proved to be useful for the macroscopic localization of recent myocardial infarcts.
