EFFECT OF INTRAVENOUS ADMINISTRATION OF HUMAN GROWTH HORMONE ON SULPHATION FACTOR ACTIVITY IN SERUM OF HYPOPITUITARY SUBJECTS

Abstract

Human growth hormone (HGH) administered as an iv injection of 2–4 mg to hypopituitary patients induced a rise in the levels of sulphation factor (SF) in serum. The low basal levels of SF were not changed during the first hour after HGH injection. Not until three hours after injection, when HGH values approached basal values, there was a significant rise in SF. The mean difference of SF at one and at three hours after HGH injection was 0.52 ± 0.11.
