Abstract
Freshly isolated hepatocytes in suspension were used to evaluate the possible effects of certain chemicals. Conditions including the choice of the incubation medium have been defined for maintaining the cells competent for a sufficient length of time. Using paracetamol alone or in combination with diethylmaleate, we have been able to show that these chemicals markedly alter the metabolic state of the cells, as indicated by an inhibition of glycogen synthesis and even by an enhancement of glycogen degradation, without modifying membrane integrity. These effects are dose-dependent and probably mediated through modification of glycogen phosphorylase activity.
