Effect of in vivo deslanoside on the uptake of serotonin into platelets. 1979

C J Helke, and K J Kellar, and R A Gillis

The purpose of our study was to determine whether deslanoside administered in vivo results in inhibition of the active transport of [3H]-serotonin into blood platelets. Experiments were performed in cats and arterial blood samples were taken prior to initiating deslanoside infusion and at the point when it appeared from the ECG that ventricular fibrillation was imminent. Toxic arrhythmogenic doses of deslanoside were found to produce a significant reduction in the uptake of [3H]-serotonin into platelets. This increase in free serotonin in plasma caused by inhibition of uptake may play a role in the cardiotoxicity of deslanoside.

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

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.

D012701 Serotonin A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator. 5-HT,5-Hydroxytryptamine,3-(2-Aminoethyl)-1H-indol-5-ol,Enteramine,Hippophaine,Hydroxytryptamine,5 Hydroxytryptamine
D013997 Time Factors Elements of limited time intervals, contributing to particular results or situations. Time Series,Factor, Time,Time Factor
