As suggested by the National Blood Council, a Hemovigilance Committee was set up in the University Hospital of Liege in 1995. A multidisciplinary discussion takes place on any action aiming at the improvement of transfusion safety, and the follow-up of its implementation. The first issue to be discussed was the set up of a detailed documentation of all blood transfusions. The data are now recorded on a single document allowing proper identification of people and products involved, and of the eventual incidents. This document has lead to a better transfusion safety and to an improved administrative management of blood transfusion. The Commission has been coordinating two multi-centric studies analyzing the consumption of fresh blood products and the incidence of transfusion reactions. Among blood-saving policies, autologous transfusion and volume reduction of samples drawn for laboratory purposes have been discussed. Other measures were taken to improve the labeling of samples for cross-mach and to actively follow-up transfusion reactions. By its actions and advises, the Commission aims to direct strategies towards a safe and rational use of blood products. [less ▲]

La strychnoxanthine, un alcaloide monoterpénique d'un nouveau type isolé à partir du Strychnos gossweileri

in Planta Medica (1984), 50(1), 93-95

Strychnoxanthine, an anhydronium base, was isolated from root barks of STRYCHNOS GOSSWEILERI, a few years ago. The structure of this new indole alkaloid is now established by spectral analysis, especially ... [more ▼]

Strychnoxanthine, an anhydronium base, was isolated from root barks of STRYCHNOS GOSSWEILERI, a few years ago. The structure of this new indole alkaloid is now established by spectral analysis, especially by (1)H NMR at 360 MHz. [less ▲]

Etude complémentaire de la cytotoxicite de la mélinonine F, alcaloide dérive de la beta-carboline

in Planta Medica (1983), 49(11), 158-161

The cellular effects of melinonine F, an alkaloid isolated from STRYCHNOS MELINONIANA (South America) and STRYCHNOS USAMBARENSIS (Central Africa), are analysed in cancer or normal cells in culture. A ... [more ▼]

The cellular effects of melinonine F, an alkaloid isolated from STRYCHNOS MELINONIANA (South America) and STRYCHNOS USAMBARENSIS (Central Africa), are analysed in cancer or normal cells in culture. A cytotoxic action is noted in both types of cells, at least for relatively high concentrations. These effects are probably due to interaction of the drug with chromatin. Physico-chemical analysis demonstrates partial intercalation of melinonine F on pure DNA IN VITRO. [less ▲]

Les Alcaloides majoritaires du Strychnos scheffleri du Zaire

in Planta Medica (1981), 42(8), 364-70

Leaves and stem barks of S. SCHEFFLERI G ILG afforded eight dihydroindole alkaloids. Four tertiary monomers (O-methyl Na-acetylstrychnosplendine, Na-acetylstrychnosplendine, strychnobrasiline and ... [more ▼]

Leaves and stem barks of S. SCHEFFLERI G ILG afforded eight dihydroindole alkaloids. Four tertiary monomers (O-methyl Na-acetylstrychnosplendine, Na-acetylstrychnosplendine, strychnobrasiline and strychnofendlerine) have been isolated from leaf material while stem barks yielded one tertiary monomer (desacetylisoretuline), one tertiary symmetrical dimer (bis-nordihydrotoxiferine) and two quaternary monomers (mavacurine and fluorocurine).
