title: [The usefullness of hyaluronate injection in patients with RA].
abstract: In this seminar, we reported the usefulness of hyaluronate injection in clinical application with patients of RA. In basic research areas, however, the mechanisms responsible for the reported beneficial clinical effects of these treatments remain unclear. There is accumulating experimental evidence to show that the receptors of HA, eg, CD-44, accelerate the inflammation of joint. Administration high molecular weight HA may modulate CD-44 sensitive macromolecular in joint inflammation in part to reduce the activity of proteinases such as MMP-9.
