BACKGROUND The commonly used cardiac glycoside, digoxin (DIG), has a narrow therapeutic window. Although some investigations were made to counteract its toxic effects, no alternate phytochemical is available till date that is more potent and safer than DIG. OBJECTIVE Our main aim was to isolate a

Factors of importance for valid digitalis assays particularly for the determination of digoxin in plasma and urine.

Four commercial radioimmunoassay (RIA) kits for digoxin varied in precision (coefficient of variation, CV within-assays 5-14%) and accuracy (up to 40%). Thus it seems that such commercial RIA-kits can reach at best a CV within-assay of 5% and a similar variation between assays. Without a good

26 mongrel dogs were given a single dose of 0.03mg/kg tritium-labelled digoxin, beta-methyldigoxin, digitoxin or ouabain 2 hrs or 95 hrs following experimental coronary occlusion. Examination of the epicardial ECG was performed by moving from intact to ischemic or necrotic zones. 60 min after

The search for endogenous digitalis has led to the isolation of ouabain as well as several additional cardiotonic steroids of the cardenolide and bufadienolide type from blood, adrenals, and hypothalamus. The concentration of endogenous ouabain is elevated in blood upon increased Na(+) uptake,

The search for an endogenous digitalis has led to the identification of the cardenolides ouabain and digoxin and the bufadienolide marinobufagenin in mammalian tissues and biological fluids. Ouabain's release from adrenal glands is under the control of epinephrine and angiotensin II; hence, its
