Abstract
Treatment of tendon by testicular hyaluronidase was found to lead to a decrease in the stability of tendon as measured by an increase in swelling, by increased solubility in dilute acetic acid and a decrease in shrinkage temp. Similar expts. with reconstituted collagen produced the same results. On the basis of this evidence and that of other workers, it is concluded that the mucopolysaccharides play an important part in stabilizing the collagenous fibers of connective tissue.
