Abstract

Physiological parameters, rates of mitochondrial respiration, high energy phosphate levels and creatine phosphokinase (CPK) activity were investigated in the hearts from control and alloxan-induced diabetic rabbits before and after 40-min total ischemia and reperfusion. Diabetic hearts demonstrated significant decreases in the rates of contraction (+dP/dt) and relaxation (-dP/dt), heart rates and cardiac work compared to control hearts. Determination of mitochondrial respiration rates in saponin-skinned fibers showed a low mitochondrial respiratory function in diabetic hearts. It was found that the ATP and ADP levels and the total and mitochondrial isoenzyme activities of CPK in diabetic hearts were lowered in comparison with control. A post-ischemic recovery of cardiac performance for diabetic hearts was better than in controls. After reperfusion diabetic hearts had increased ATP levels. The data obtained demonstrate some abnormalities of both cardiac performance and energy metabolism in the hearts of diabetic animals and a decreased sensitivity of the latter to ischemic injury.
