Growth Hormone

Abstract

HUMAN growth hormone is the most recent addition to the list of clinically useful hormones, though it will be some time before its range of usefulness is defined and undoubtedly a still longer time before an adequate source of clinically active material is devised. The delay in its clinical application is largely attributable to the tardy recognition of the evolutionary changes both in the chemical structure of growth hormone and in the tissue receptors for the growth-promoting agent.1 2 3 4 The growth hormone synthesized by human pituitary glands is a different substance from that made by beef, and both differ from that . . .
