HA is major components in human stromal cells,

vitreous, synovial fluid and other connective tissue in
the body HA plays an important role in retaining

water, maintain extracellular space, adjusting

osmotic pressure, lubricating and improving cells

reparation.


As a major components of intercellular

substance, HA directly takes part in electrolyte

alternate control between cells and exerts the

function of message filter of physics and molecule.

High molecular HA can restrain the movement,

multiplication and phagocytosis of cells while low

molecular HA plays a role of stimulation.

   HA has unique physicochemical properties and

physiological functions. It has been widely applied

in the pharmaceutical industry. HA can be used as

viscoelastic materials in intraocular lens implantation
and as fillers in articular surgery against

osteoarthritis, rheumatoid arthritis etc. It is also used
as medium in eye drops extensively.



   Furthermore, HA is helpful in preventing post-

surgery conglutination and improving wound

healing. The compound as a result of its reaction to

other medicine may play a role of sustained release,
thus achieving the purpose of targeted and timed

release. With the development of medical science,

HA will become more and more useful in the field of

medicine.
