Ils présentent des propriétés thérapeutiques intéressantes, notamment des propriétés hypocholestérolémiantes qui seront mises en valeur par les résultats des essais qui sont donnés ci-dessous après les résultats des essais toxicologiques.
1/ Essais toxicologiques :
On donne ici, à titre d'exemples illustratifs, les
<EMI ID=67.1>
d'aluminium.
L'étude toxicologique a porté sur :
a) La toxicité algue : Les DL 50/24h sont les suivantes:
- Administration par tubage gastrique : 4,0 g/kg <EMI ID=68.1>
- Administration par voie intra-péritonéale : l,2g/kg chez la souris Swiss, et 1,85 g/kg chez le rat Wistar; b) La toxicité sub-chronique et chronique chez le rat et le lapin : à 'la dose de 200 mg/kg le produit est parfaitement toléré.
<EMI ID=69.1>
<EMI ID=70.1>
<EMI ID=71.1>
A titre d'exemple, les essais sur le rat sont décrits ci-après:
<EMI ID=72.1> nium par kg de poids corporel et par jour, pendant 15 jours, en même temps qu'un régime hypocholestérolémiant. Des rats non traités mais soumis au même régime ont servi de témoins. Les chiffres du Tableau ci-dessous représentent la moyenne de 40 animaux.
<EMI ID=73.1>
L'étude de ce Tableau montre que les animaux traités

éléments traduisant les dyslipémies inférieures de :
- 32 % pour le cholestérol total, <EMI ID=75.1>
- 21 % pour le KUNKEL PHENOL K2,
- 17 % pour le BURSTEIN, <EMI ID=76.1>
- 31 % pour les phospholipides,
- 32 % pour les lipides totaux.
<EMI ID=77.1>
rate d'aluminium possède des propriétés hypocholestérolémiantes importantes.
<EMI ID=78.1>
avec chacun des autres dérivés a'permis d'obtenir des résultats sensiblement identiques.
3/ Essais cliniques
On donnera maintenant, à titre d'exemple, quelques observations cliniques typiques parmi celles qui ont été effectuées.
<EMI ID=79.1>
Madame CER.... Mireille, 54 ans, présente une hypercholestérolémie de découverte systématique. Il s'agit d'une femme pesant 61 Kg pour 1,65 m qui vient, adressée par un ophtalmologiste, pour bilan d'une hypercholestérolémie dont la traduction est oculaire. Sur le plan somatique, les bruits du coeur sont normaux; la tension est modérément élevée à 16/9. Le pouls est régulier à 80 pulsations par minute.

aluminum.
The toxicological study focused on:
a) Algae toxicity: The LD 50 / 24h are as follows:
- Administration by gastric tube: 4.0 g / kg <EMI ID = 68.1>
- Intra-peritoneal administration: 1.2 g / kg in Swiss mice, and 1.85 g / kg in Wistar rats; b) Sub-chronic and chronic toxicity in rats and rabbits: at a dose of 200 mg / kg the product is perfectly tolerated.
