[Radio-immunologic determination of hypophyseal vasotocin by Phoxinus laevis during experimental modification of osmotic equilibrium].
Hypophysial vasotocin of Phoxinus laevis is determined by radio-immunoassay. With different sea water dilutions it is shown that hypophysial vasotocin concentration varies with ambient salinity. This fact agrees with histological pictures. Moreover, in comparison with the results of other authors, it is established that the hypophysial morphological modifications appeared only after the hormonal changes.
