Abstract
The regulation of hepatic gluconeogenesis was studied in rats made septic by cecal-ligation and puncture technique. Blood glucose was not significantly different in septic rats, but lactate, pyruvate, and alanine were markedly increased. Conversely, blood ketone body concentrations were markedly decreased in septic rats. Both plasma insulin and glucagon were markedly elevated in septic rats. The maximal activities of glucose 6-phosphatase, fructose 1,6-biphosphatase, pyruvate carboxylase, and phosphenolpyruvate carboxykinase were decreased in livers obtained from septic rats suggesting a diminished hepatic gluconeogenesis.
