  • Title: Effect of ischaemic limb injury on the rates of metabolism of ketone bodies in starved rats.
    Author: Barton RN.
    Journal: Biochem J; 1976 May 15; 156(2):233-8. PubMed ID: 942408.
    Abstract:
    1. Rats starved for 30h were injected with trace amounts of [3-14C]acetoacetate and beta-hydroxy[3-14C]butyrate 1h after ischaemic limb injury in a 20 degrees C environment, and the concentrations and radioactivities of blood ketone bodies were determined at intervals. 2. Starvation alone raised the rates of production and utilization of beta-hydroxybutyrate plus acetoacetate about 3.7-fold, but lowered their metabolic clearance rates by about 50%. In the starved rat ketone-body oxidation could account for up to 30% of whole body O2 consumption. 3. Injury in starved rats lowered the rates of production and utilization of both beta-hydroxybutyrate and acetoacetate, the combined fall of about 37% slightly exceeding the concomitant fall in whole-body O2 consumption. The concentration of beta-hydroxybutyrate decreased after injury, but its metabolic clearance rate was unaltered; the concentration of acetoacetate rose slightly and its metabolic clearance rate fell.
