Effect of ouabain on adrenal potassium balance in sheep. 1975

E H Blaine, and J P Coghlan, and D A Denton, and K J Hardy, and B A Scoggins

A previous study revealed that ouabain caused a marked decrease in aldosterone secretion, but the adrenal K status was not clear from those data. The present study investigated the magnitude and time course of change in adrenal K balance when ouabain was administered into the adrenal arterial supply of the in situ adrenal of conscious sheep. Ouabain at an adrenal arterial plasma concentration of approximately 2.4 X 10(-4) M produced a striking negative adrenal K balance within 10 min of beginning the infusion. The adrenal continued to lose K during the 30-min infusion and for 30 min thereafter. The mean total K loss was 42.3 +/- 7.9 muequiv/adrenal (n = 11). Thirty minutes after ending the ouabain infusion, the adrenal began taking up K but had not recovered its normal K complement by 60 min.

UI MeSH Term Description Entries
D010042 Ouabain A cardioactive glycoside consisting of rhamnose and ouabagenin, obtained from the seeds of Strophanthus gratus and other plants of the Apocynaceae; used like DIGITALIS. It is commonly used in cell biological studies as an inhibitor of the NA(+)-K(+)-EXCHANGING ATPASE. Acocantherin,G-Strophanthin,Acolongifloroside K,G Strophanthin
D011188 Potassium An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D005260 Female Females
D000311 Adrenal Glands A pair of glands located at the cranial pole of each of the two KIDNEYS. Each adrenal gland is composed of two distinct endocrine tissues with separate embryonic origins, the ADRENAL CORTEX producing STEROIDS and the ADRENAL MEDULLA producing NEUROTRANSMITTERS. Adrenal Gland,Gland, Adrenal,Glands, Adrenal
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
