Abstract

A single neonatal treatment of rats with vitamin D3, gibberellin, allylestrenol or diethylstilbestrol (DES) influenced the ouabain binding capacity of myocardial Na, K-dependent ATP-ase. Of the active molecules tested, vitamin D3, DES and gibberellin had appreciable impact on myocardial ouabain receptors, enhancing and depressing their activity, respectively. The thymic dexamethasone and uterine estrogen receptors did not alter their binding capacity in response to neonatal exposure to vitamin D3 or gibberellin.
