Beschreibung
Zusammenfassung:	An oxidized composite comprising a water-soluble carboxypolysaccharide and ultrafine magnetic iron oxide particles. It has an extremely reduces toxicity and an excellent stability, exhibits scarcely any or no hypotensive activity even if directly administered into the blood vessel of an animal, is reduced in the activity of platelet agglutination, and is useful in the medical field as, for example, a contrast medium for MRI and a pyrogenic agent for thermotherapy. L'invention se rapporte à un composite oxydé comprenant un carboxypolysaccharide hydrosoluble et des particules d'oxyde de fer magnétique ultrafines. Ce composite présente une toxicité extrêmement réduite et une excellente stabilité, il ne possède aucune ou pratiquement aucune action hypotensive, même lorsqu'il est administré directement dans le système sanguin d'un animal, il a un effet d'agglutination des plaquettes réduit et il est utile dans le domaine médical par exemple comme milieu de contraste pour l'imagerie par résonance magnétique et comme agent pyrogène en thermothérapie.
