Cov khoom tseem ceeb
Hyaluronic acid yog ib qho acidic mucopolysaccharide.Xyoo 1934, Meyer, tus kws tshaj lij ntawm ophthalmology ntawm Columbia University hauv Tebchaws Meskas, thawj zaug cais cov tshuaj no los ntawm bovine vitreous.Hyaluronic acid, nrog nws cov qauv molecular tshwj xeeb thiab lub cev thiab tshuaj lom neeg, qhia txog ntau yam kev ua haujlwm ntawm lub cev tseem ceeb hauv lub cev, xws li lubricating pob qij txha, tswj cov permeability ntawm vascular phab ntsa, tswj cov diffusion thiab kev ua haujlwm ntawm cov protein, dej thiab electrolytes, thiab txhawb kev kho qhov txhab.
Lub hom phiaj tseem ceeb
Cov tshuaj biochemical nrog cov nqi kho mob siab yog siv dav hauv ntau yam kev ua haujlwm ntawm lub qhov muag, xws li kev cog hniav lo ntsiab muag, kev hloov pauv ntawm pob txha thiab phais tiv thaiv glaucoma.Nws kuj tseem siv tau los kho mob caj dab thiab ua kom lub qhov txhab zoo.Thaum siv cov tshuaj pleev ib ce, nws tuaj yeem ua lub luag haujlwm tshwj xeeb hauv kev tiv thaiv daim tawv nqaij, ua kom cov tawv nqaij moist, du, muag muag, muag muag thiab elastic, thiab muaj lub luag haujlwm ntawm kev tiv thaiv wrinkle, tiv thaiv wrinkle, kev zoo nkauj thiab kev kho mob, thiab kho cov tawv nqaij physiological functions.

Hyaluronic acid yog lub luag haujlwm tseem ceeb ntawm cov ntaub so ntswg sib txuas xws li tib neeg cov khoom sib txuas, lub cev vitreous, cov kua dej sib koom ua ke, thiab lwm yam. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj dej, tswj qhov chaw extracellular, tswj osmotic siab, lubricating thiab txhawb kev kho cell hauv lub cev. .Hyaluronic acid molecules muaj ntau ntawm carboxyl thiab hydroxyl pawg, uas tsim intramolecular thiab intermolecular hydrogen bonds nyob rau hauv aqueous tov, uas ua rau nws muaj ib tug muaj zog dej tuav nyhuv thiab muaj peev xwm ua ke ntau tshaj 400 lub sij hawm nws tus kheej dej;Ntawm qhov siab dua, nws cov tshuaj aqueous muaj qhov tseem ceeb viscoelasticity vim yog cov txheej txheem tertiary network complex tsim los ntawm nws cov kev sib cuam tshuam intermolecular.Hyaluronic acid, raws li lub hauv paus ntsiab lus ntawm lub intercellular matrix, ncaj qha koom nyob rau hauv cov kev cai ntawm kev sib pauv ntawm electrolytes nyob rau hauv thiab sab nraum lub cell, thiab plays lub luag hauj lwm raws li ib tug lim ntawm lub cev thiab molecular ntaub ntawv.Hyaluronic acid muaj cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg thiab kev ua haujlwm ntawm lub cev, thiab tau siv dav hauv tshuaj.
Hyaluronic acid tuaj yeem siv los ua tus neeg sawv cev viscoelastic rau ophthalmic intraocular lens implantation, ua ib qho muab tub lim rau kev phais mob xws li osteoarthritis thiab mob caj dab rheumatoid.Nws yog dav siv los ua qhov nruab nrab hauv qhov muag tee, thiab tseem siv los tiv thaiv kev ua haujlwm tom qab adhesion thiab txhawb kev kho ntawm daim tawv nqaij qhov txhab.Lub compound tsim los ntawm cov tshuaj tiv thaiv ntawm hyaluronic acid nrog rau lwm yam tshuaj plays ib tug qeeb tso lub luag hauj lwm ntawm cov tshuaj, uas muaj peev xwm ua tau raws li lub hom phiaj ntawm lub hom phiaj thiab lub sij hawm tso tawm.Nrog rau txoj kev loj hlob ntawm kev kho mob technology, hyaluronic acid yuav ntau thiab ntau lug siv nyob rau hauv cov tshuaj.
