Abstract
Oxygen consumption and plasma lactate and pyruvate were measured in normal, eviscerated, eviscerated-hepatectomized, and eviscerated-hepatectomized-insulin-treated dogs before and after 5 min of mild exercise (direct tetanic stimulation of the muscles of the hind limbs.) The excess consumptions of oxygen during recovery were the same in all four groups; however, lactate and pyruvate removal were markedly impaired in the operated animals. This indicates a complete dissociation between oxygen consumption and metabolite removal during recovery from exercise.
