[Turnover of free adenine nucleotides of the isolated and perfused rabbit heart].
The turnover of free adenine nucleotides was studied in the perfused rabbit heart by the decline in radioactivity 3 h 30 after administration of a single pulse of tritiated adenine. The radioactivity of the perfusate was followed during the experiments. About 7% of the labelled adenine nucleotides were renewed by hour and 1,5% of the radioactivity was lossed by hour in the perfusion fluid.
