Abstract

Une nouvelle hyaluronidase (HAase) est isolée du surnageant d'une culture de tissu cancéreux de l'utérus humain par une électrophorèse sur un gel de dodécyle sulfate de sodium et de polyacrylamide en utilisant de l'acide hyaluronique, un sulfate de chondroïtine modifié ou similaire comme substrat. La HAase obtenue hydrolyse l'acide hyaluronique à un pH de 3,5 à 7,5, mais pas le sulfate de chondroïtine et elle est utile, par exemple, pour la mise au point de remèdes contre les ÷dèmes cérébraux, l'infarctus du myocarde et similaire, comme adjuvant pour des médicaments et comme inhibiteur de la hyaluronidase.
