A method for treating a herniated disk by chemonucleolysis, comprising contacting the herniated disk with an amount of a soluble hyaluronidase glycoprotein (sHASEGP) sufficient to effect chemonucleolysis of the hernia, wherein the sHASEGP is a soluble neutral active glycoprotein that contains at least one sugar moiety that is covalently attached to an asparagine residue;
- and
- the sHASEGP contains a sequence of amino acids included in SEQ ID NO:
- 1 or a sequence that has at least about 91% amino acid sequence identity with a sequence of amino acids included in SEQ ID NO:
- 1, whereby the sHASEGP is soluble, N-glycosylated and neutral active.
