Fluoride intake through consumption of tap water and bottled water in Belgium.

There is a tendency to align higher levels of fluoride in natural mineral water with the existing higher levels in tap water. Treatment of natural mineral waters could harm the preservation of their natural character. In this study fluoride intake through bottled and tap water consumption in the Belgian adult population was assessed, taking into account regional differences.

Characterization of the neurotoxicity induced by the extract of Magnistipula butayei (Chrysobalanaceae) in rat: effects of a new natural convulsive agent.

This study was designed to document convulsant and neurotoxic properties of extracts of a tropical tree, Magnistipula butayei subsp. Montana, and to investigate the involvement of the glutamatergic system in these effects. Continuous behavioral observations and electroencephalographic (EEG) records were obtained after per os administration of an aqueous extract of Magnistipula (MBMAE) in rats.

Chemical and biological investigations of a toxic plant from Central Africa, Magnistipula butayei subsp. montana.

Magnistipula butayei subsp. montana (Chrysobalanaceae) is known, in the Great Lakes Region, to possess toxicological properties. In this paper, we investigated the acute toxicity (dose levels 50-1600 mg/kg) of its aqueous extract, administered orally to adult Wistar rats.

[Glycoalkaloids in potatoes].

With its high concentration in starch and vitamins (C, B1 and B2), the potato, cooked in water, is a very interesting source of energy. Unfortunately, it also contains natural toxins: the glycoalkaloids. Their variable amount can depend, in particular, on different environmental factors.

[Cannabis, status in 2001-2002].

Even though its use becomes common, cannabis remains a narcotic, the risks of which are nowadays better known. Its therapeutic value still needs to be scientifically demonstrated.
