glycolide CAS: 502-97-6

Glycolide yog ib qho tshuaj sib xyaw ua ke uas siv tau ntau yam, tshwj xeeb tshaj yog hauv kev kho mob, kev ntim khoom, thiab kev ua liaj ua teb. Nws siv tseem ceeb hauv kev tsim cov polyglycolic acid (PGA), uas yog ib qho polymer uas lwj tau yooj yim uas zoo rau kev siv kho mob. PGA siv dav hauv kev tsim cov xov uas nqus tau, uas muab kev txhawb nqa ib ntus hauv kev kho cov ntaub so ntswg thiab maj mam lwj thaum lub cev kho, tshem tawm qhov xav tau kev tshem tawm. Cov yam ntxwv no ua rau glycolide yog ib qho tseem ceeb hauv kev tsim cov khoom siv phais siab heev thiab cov txheej txheem xa tshuaj, qhov twg kev tswj hwm kev tso tawm thiab kev sib raug zoo ntawm biocompatibility yog qhov tseem ceeb. Hauv kev lag luam ntim khoom, cov polymers glycolide-based tau nyiam ntau dua rau kev tsim cov yeeb yaj kiab thiab cov thawv uas lwj tau yooj yim thiab lwj tau. Cov ntaub ntawv no pab txo cov khib nyiab yas thiab kev cuam tshuam rau ib puag ncig thaum tswj kev ua haujlwm zoo, ua rau lawv yog cov kev xaiv zoo rau cov neeg siv khoom thiab cov lag luam uas paub txog ib puag ncig. Tsis tas li ntawd, glycolide raug tshawb nrhiav hauv kev siv ua liaj ua teb, xws li kev tsim cov yeeb yaj kiab mulch uas lwj tau yooj yim uas txhim kho kev noj qab haus huv ntawm av thiab txo cov yas ua qias tuaj hauv cov teb. Cov yeeb yaj kiab no lwj tom qab siv, yog li pab txhawb rau kev ua liaj ua teb ruaj khov. Glycolide lub peev xwm los tsim cov copolymers nrog lwm cov monomers, xws li lactide, tso cai rau kev hloov kho cov khoom siv, kho lawv rau cov ntawv thov tshwj xeeb. Qhov kev hloov pauv no txhim kho kev ua tau zoo ntawm cov khoom xws li cov tshuaj tswj hwm-tso tawm mus rau cov ntim khoom zoo rau ib puag ncig. Zuag qhia tag nrho, glycolide sawv tawm ua tus neeg ua si tseem ceeb hauv kev tsim cov khoom siv ruaj khov uas ua tau raws li qhov xav tau ntawm ntau yam lag luam thaum txhawb kev saib xyuas ib puag ncig thiab kev nyab xeeb kev noj qab haus huv.
