Further evidence for the humoral stimulation of the liver: effect of a pituitary peptide

ABSTRACT

The capacity of a peptide isolated from hypophysis (HTH) to affect liver function is further supported by the results of pilot experiments on lipid and protein metabolism. Administration of purified peptide to rats induces reduction in plasma proteins and increase in plasma cholesterol with an abnormal free/esterifield cholesterol ratio in liver. Cholesterol in bile and bile volume excretion increase above normal and the concentration of other substances known to be modified by liver activity shows values different to normals.
