Summary

X-ray microanalysis was carried out on sections from isolated hearts perfused with a modifiedKrebs-Henseleit solution with or without isoproterenol. Changes in P, Ca and Zn concentrations could be detected after isoproterenol and some correlation with hemodynamic and morphological parameters was observed. Ratios between P/Ca in myonuclei and the ratios of interstitial cell to myofiber nucleus calcium were related directly to the state of the heart.

Röntgen-Mikroanalyse des isolierten, perfundierten Rattenherzens

Zasammenfassung

An Schnitten von isolierten Herzen, die mit einer modifiziertenKrebs-Henseleit-Lösung mit oder ohne Zusatz von Isoproterenol perfundiert worden waren, wurde eine Röntgenmikroanalyse durchgeführt. Nach Isoproterenolperfusion konnten Veränderungen der P-, Ca- und Zn-Konzentrationen und eine Beziehung dieser Änderungen zu hämodynamischen und morphologischen Parametern festgestellt werden. Das P/Ca-Verhältnis in den Kernen der Muskelfasern und die Calcium-Relation zwischen den Kernen der interstitiellen Zellen einerseits und der Myokardfasern andererseits zeigten eine direkte Beziehung zum Zustand des Herzens.
