Die Wirkung von Ouabain auf die Elimination von Noradrenalin aus der Perfusionsfl�ssigkeit des isolierten Kaninchenherzens

1966

Isolated rabbit hearts were perfused with Tyrode solution containing 10 ng/ml (-)-noradrenaline for 20 min. The uptake by the heart of noradrenaline was calculated by estimating the percentage of amine removed from the perfusion fluid during a single passage through the heart. Previous experiments have shown that the amount of noradrenaline removed from the perfusion fluid corresponds well to the amount retained by the heart. In control experiments, the mean removal (elimination) of noradrenaline was 50±1.7% of the amount infused as measured biologically and 46±2.2% as measured fluorimetrically. Ouabain was added to the perfusion fluid at concentrations ranging from 2.74·10−7 to 2.0·10−6 mo…
