Abstract

Perfused liver carnitine palmitoyl transferase (CPT) activity and ketone body output were determined in streptozotocin - treated and untreated Sprague-Dawley and Zucker rats. Streptozotocin enhanced liver ketogenic capacity and CPT activity in both these strains. No difference was observed in CPT activity or in ketone body production between the fatty and lean Zücker strains. Glucagon, added directly to the perfusate, had no influence on ketone body output and only in the livers of obese Zücker rats increased CPT activity.
