title: [L-propionylcarnitine taurine amide induces the metabolic recovery of the isolated postischemic rat heart].
abstract: The effect of reperfusion with L-propionyl-carnitine-taurinammide 1 mM was evaluated on the metabolic recovery of the isolated postischemic rat heart. Data referring to the tissue concentration of the high-energy phosphates, oxypurines, nucleosides, nicotinic coenzymes, lactate and pyruvate indicate that L-propionyl-carnitine-taurinammide significantly improves the metabolism of the reperfused myocardium. In particular, ATP, creatinphosphate, GTP, sum of adenine nucleotides and the energy charge resulted 1.80, 1.83, 3.47, 1.47 and 1.20 times higher respectively than the corresponding values recorded in control reperfused heart (p < 0.01 all). These data, out of supplying the necessary biochemical support to the beneficial effects of L-propionyl-carnitine-taurinammide on hemodynamics obtained in previous studies, suggest that L-propionyl-carnitine-taurinammide might represent a useful tool for the pharmacological treatment of myocardial infarction.
