title: Comparative study of cardioprotective effects of uridine-5'-monophosphate and uridine-5'-triphosphate during the early periods of acute myocardial ischemia.
abstract: In experiments on rats, uridine-5'-monophosphate and uridine-5'-triphosphate reduced the intensity of anaerobic glycolysis and preserved glycogen stores and creatine phosphate balance during the first 60 min after occlusion of the left coronary artery. However, the energy-protective effect of uridine-5'-triphosphate developed 15 min later than the effect of uridine-5'-monophosphate. Uridine-5'-monophosphate, but not uridine-5'-triphosphate, reduced T wave amplitude on ECG and decreased the volume of ischemic injury to the myocardium.
