31P-MRS study of bio-energy recovering phenomenon.


The ATP and creatine phosphate (PCr) contents in isolated guinea-pig hearts were determined by 31P-MRS measurement at 80.75 MHz using the Langendorff technique. Reperfusion of post-ischemic hearts with adenosine for 180 minutes increased ATP to 117.4% and decreased PCr to 59.8% of the preischemic value. Reperfusion without adenosine did not increase ATP and… (More)
