Acute hepatic failure (AHF) is a physiopathological entity difficult to reproduce experimentally but necessary to evaluate new therapies such as bioartificial liver (BAL) or hepatocyte transplantation (HcTX). Two main animal models are available: surgical or chemical induction of an AHF. Many authors have assessed BAL or HcTX with such models and observed increased survival rate in the treated groups. However, during AHF, severe hypoglycemia takes place. Some authors have shown that adjunction of glucose in beverage after surgically induced AHF may induce by itself an improvement of survival rate.
