Abstract

Préparation d'acide hyaluronique modifié chimiquement (Hylan) caractérisé par la présence de petites quantités (0,005-0,05% en poids) de groupes de réticulation d'aldéhyde liés par covalence aux chaines moléculaires d'acide hyaluronique, et son procédé d'obtention, comprenant le traitement d'acide hyaluronique in situ dans des tissus animaux contenant celui-ci par un mélange de traitement comprenant un réactif (d'une manière caractéristique un aldéhyde), qui réagit vis-à-vis de l'acide hyaluronique et des protéines contenues dans le tissu animal.
