title: Evidence for an accelerated adaptation to starvation in chronic uremia.
abstract: During a 72-hr period of starvation plasma levels of glucose and immunoreactive insulin fell to a greater extent, and alanine, free fatty acid, and glycerol concentrations were higher in fasted chronically uremic rats than in nonuremic controls. These changes, in conjunction with a significant increase in the uremic group's activity of phosphoenolypyruvate-carboxykinase, the rate-limiting enzyme in hepatic gluconeogenesis, after only 12 hr of fasting suggest that alterations in glucose metabolism in uremia may contribute to an exaggeration and acceleration of the metabolic consequences of starvation.
