Résumé

La secrétion hormonale de neurohypophyses isolées de rat a été estimée à l'aide d'un test d'éjection du lait. Au moment de la dépolarisation des terminaisons neurosecrétrices, il y a compétition entre le sodium et le calcium externes pour d'hypothétiques sites membranaires. Pour des concentrations de calcium inférieures ou égales à la concentration physiologique, la libération hormonale est fonction du rapport [Ca2+]/[Na+]2 dans le milieu externe.
