title: The differential effect of insulin in vivo on the peripheral utilization of glucose and ketone bodies in the rat.
abstract: This in vivo study assessed the immediate effects of insulin on glucose and ketone body utilization in the fed, fasted, and diabetic ketoacidotic rat. The experimental design consisted of the functional removal of the liver (the site of glucose and ketone body production) and the pancreas from the anesthetized animals. This surgical procedure permitted the assessment of the effect of exogenously administered insulin on the rate of both glucose and ketone body utilization by peripheral tissues. Insulin exerted hypoglycemic activity in all three metabolic states studied. This hypoglycemic activity contrasted to the lack of demonstrable effect of this hormone on ketone body uptake by peripheral tissues. It was concluded that in the rat, the immediate effect of insulin, i.e. within 30 minutes, was to exert hypoglycemic activity without simultaneous hypoketoniemic activity.
