Creatine kinase activity (the left panel) and the amount of purines and bases (ATP metabolites; the right panel) in the perfusate eluted from normoxic (Normoxia) or ischaemic/reperfused hearts (Isch/Rep) untreated or treated with 10, 30, or 100 μM propranolol. Each value represents the mean±s.e.mean of five experiments. ^*Significantly different from the untreated group (0 μM propranolol; P<0.05). #Significantly different from the normoxic heart of the untreated ischaemic/reperfused group (P<0.05).
