In partially hepatectomized rats, the activity of phenylalanine hydroxylase decreased in the regenerating liver but not in the kidney. The concentration of corticosterone in the plasma of hepatectomized rats increased, and phenylalanine hydroxylase, despite being cortisol inducible, decreased in these as well as simultaneously adrenalectomized rats, showing lack of correlation between the changes of the steroid and the enzyme during the regeneration process. The decrease in the enzyme activity could be prevented by administering, during hepatic regeneration, only noradrenaline and adrenergic blocking agents, among the many hormones and phenyl compounds tested. A decrease in hepatic phenylalanine hydroxylase was also observed during two other conditions of hepatocyte cell proliferation obtained after giving chlorophenoxyisobutyrate and α-hexachlorocyclohexane.
