The metabolism of specimens of human adipose tissue exposed to different concentrations of halothane was studied. Halothane was added to the incubation medium directly or via the gas phase above the medium. The basal lipolysis was significantly increased by low concentrations of halothane. Higher concentrations clearly diminished the lipolysis, but here, in spite of the inhibitory effect on the basal lipolysis, the lipolytic effect of noradrenaline expressed as percent increment was increased. The rate of lipid synthesis from glucose was reduced when halothane was present in the gas phase. The effect of insulin on glucose metabolism was not affected by the presence of halothane, while the antilipolytic action was abolished by high concentrations of halothane. The results show that halothane may exert dual effects on the mobilization of lipids from human adipose tissue; at low concentrations halothane enhances the basal lipolysis, while at higher concentrations it exerts inhibitory effects.
