I-SODIUM HYALURONATE
Isingeniso
I-Sodium hyaluronate, eyaziwa nangokuthi i-sodium vitreous acid, iyisithako esisebenzayo ngokwezinto eziphilayo esitholakala kabanzi emzimbeni womuntu. Iyi-polymeric straight-chain mucopolysaccharide eyenziwe nge-polymeric yi-glucoaldehyde kanye ne-acetylaminohexose ukwakha iyunithi ye-disaccharide, enesisindo sama-molecule esingu-1 million. Isixazululo esijiyile nesinwebekayo sakhiwa emanzini, esine-acidity yomzimba kanye namandla e-ionic. I-Chemicalbook. Ukwakheka kwayo kwama-molecule kuyashintshashintsha, ngakho-ke ingadluliswa nangenaliti encane yomjovo. Hlanza izinto ezingabangeli ukuvuvukala ku-sodium hyaluronate.
SEBENZISA
I-sodium hyaluronate inomphumela wokukhuthaza ukuphulukiswa kwenxeba. I-sodium hyaluronate ingakha isithiyo se-macromolecular reticular ebusweni bezicubu zamehlo, ivimbele izinto ezivuvukalayo ukuthi zingangeni esilondeni nasendaweni egxile kuyo, futhi ingathuthukisa kakhulu i-viscosity kanye nokunamathela kwesisombululo somuthi, ukuze incwadi yamakhemikhali igcinwe ebusweni be-cornea isikhathi eside futhi igxile, ifinyelele umphumela wesikhathi eside nonamandla. I-sodium hyaluronate ingazinzisa ifilimu yokudabuka, yandise isikhathi sokudabuka kwefilimu yokudabuka, futhi inciphise izimpawu zamehlo omile. Isetshenziselwa ukusha kwe-cornea okubangelwa yi-keratitis, izilonda ze-cornea, umonakalo we-cornea noma ezinye izinto zamakhemikhali nezomzimba.
