description

Steady state blood levels of ketone bodies during infusions of acetoacetate at various rates have been compared in healthy and diabetic rats. The characteristics of the metabolic elimination of ketone bodies from the blood are completely changed in diabetic rats. Whereas steady state levels of ketone bodies increase linearly with the infusion rate in healthy rats, this increase is exponential in diabetic animals. This difference, which is due to an impaired metabolic elimination, becomes evident only above a dosage of 50 μmoles acetoacetate per kg per min. Chronic treatment with insulin for 4–6 days, but not acute insulin injection, restores the capacity of diabetic rats to metabolize ketone bodies at normal rates. The results are discussed with regard to the difference between the stable ketosis of starvation and the labile diabetic ketoacidosis.
