The control by vasopressin of carbohydrate and lipid metabolism in the perfused rat liver.
Vasopressin-induced glucose release from the perfused livers of fed rats is diminished in the presence of insulin or following adrenal ablation. The reduced rate of glucose release following vasopressin treatment in the perfused livers of adrenalectomized rats was restored towards the control value by cortisol treatment in vivo. Vasopressin did not influence the total rate of fatty acid synthesis in the livers of fed rats perfused with medium containing glucose and two concentrations of lactate. The contribution of these precursors to hepatic fatty acid synthesis and CO2 production was similarly uninfluenced by vasopressin. Vasopressin casued a transient increase in the release of K+ by the perfused liver which was observed within 2 min of hormone administration. These results are discussed in relation to the possible mode of action of vasopressin in the liver.
