Strophanthidin was used to synthesize acetylstrophanthidin and the effect on neurotransmitter release from dog saphenous vein was studied.3

Strophanthidin is a cardiotonic steroid that elevates the activity of Na+/K+-ATPase in cardiac myocytes.1 It decreases the potassium content and raises the sodium content in rabbit renal cortex slices.2
Tissue damage at the time of organ transplantation has a negative impact on the subsequent success of the procedure, both in the immediate and longer term. Hypothermia is the principal element used to prolong organ viability ex vivo, but paradoxically

Cell-attached and whole cell recording techniques were used to study the effects of electrogenic sodium pump on the excitability of rat suprachiasmatic nucleus (SCN) neurons. Blocking the sodium pump with the cardiac steroid strophanthidin or zero K+ increased the spontaneous
Three horses died as a result of eating grass hay containing summer pheasant's eye (Adonis aestivalis L.), a plant containing cardenolides similar to oleander and foxglove. A 9-year-old thoroughbred gelding, a 20-year-old appaloosa gelding, and a 5-year-old quarter horse gelding

1 The effect of alpha-adrenoceptor antagonists upon neurotransmitter release evoked by cardiac glycosides from sympathetic nerve terminals has been investigated in dog saphenous vein. 2 In rings of saphenous vein preloaded with [3H]-noradrenaline, acetylstrophanthidin (ACS) caused a concentration-dependent efflux of

Rhythmic motor behaviours consist of alternating movements, e.g. swing-stance in stepping, jaw opening and closing during chewing, and inspiration-expiration in breathing, which must be labile in frequency, and in some cases, in the duration of individual phases, to adjust to
