title: The budgerigar (Melopsittacus undulatus) as endocrinological test model. Thyroxine transport in blood.
abstract: By comparing in-vivo and in-vitro investigations the transport protein of thyroxine in the budgerigar (Melopsittacus undulatus) was determined. Electrophoretic and auto-radiographic methods were applied. Both investigations show the alpha-globulin to be a thyroxine-binding protein. The contradictions to other investigators are discussed. The experimental animal as an endocrinological model of the thyroid for questions of human medicine is recommended.
