New Neurohypophysial Principle in Foetal Mammals

Abstract

FROM a study of the ratio of vasopressor to oxytocic activities (the V/O ratio) in foetal mammals, we have found preliminary evidence for a hormone formerly thought to be confined to the lower vertebrates. Because the hormone occurs only in the foetus, it carries the hint of molecular recapitulation and suggests that hormonal structure may depend not only on the species but also on the stage of development.
