Daim ntawv thov ntawm GELATIN hauv BIOMEDICAL MATERIALS
Gelatin, ib yam khoom siv biopolymer, yog ib qho khoom noj khoom haus uas tau npaj los ntawm kev siv dej tsis zoo ntawm cov pob txha tsiaj, cov tawv nqaij, cov leeg, cov leeg thiab cov nplai.Tsis muaj ib yam dab tsi piv rau cov khoom siv tshuaj biomedical hauv gelatin, vim tias nws cov biodegradability, biocompatibility zoo, gel thiab tus nqi qis.Yog li, gelatin tau dav siv los ua cov tshuaj ib txwm siv hauv cov ntaub ntawv biomedical.

Kev hloov ntshav yog qhov tsim nyog nyob rau ntau qhov xwm txheej, xws li kev phais ib nrab lossis mob hnyav heev.Txawm li cas los xij, qhov tsis txaus ntawm cov ntshav, kev teeb tsa cov ntshav nyuaj, thiab kev pheej hmoo ntawm cov ntshav allogeneic kuj cuam tshuam rau lub sijhawm, kev ua tau zoo thiab kev nyab xeeb ntawm kev kho mob mus rau qhov zoo.Cov txheej txheem ntawm kev hloov ntshav plasma tuaj yeem daws cov teeb meem no, yog li nws muaj peev xwm siv tshuaj kho mob tau zoo thiab kev txhim kho qhov chaw.Yog li ntawd, cov ntaub ntawv gelatin, xws li succinyl gelatin thiab polygelatin peptide, tau siv dav los ua cov ntshav hloov pauv hauv tsev kho mob.Gelatin plasma hloov pauv yuav siv rau thaum muaj xwm txheej ceev xws li txo cov ntshav ntim thiab poob siab.Colloid nkag mus tuaj yeem nthuav cov ntshav ntim thiab txhim kho microcirculation.Gelatin hloov ntshav muaj ntau yam zoo, xws li degradability, cov tswv yim loj, tsis muaj tshuaj lom, tsis muaj tshuaj tiv thaiv kab mob thiab lwm yam.
HemostaticMkhoom
Nyob rau hauv xyoo tas los no, cov zej zog kho mob tau them nyiaj ntau dua rau kev tsim cov khoom siv hemostatic tshiab.Absorbable gelatin sponge tau nyiam ntau xim vim nws muaj qhov zoo ntawm cov nyhuv hemostatic, tsis tshua muaj nqi thiab muaj zog ua haujlwm.Lub tshuab hemostatic ntawm gelatin hemostatic daim txhuam cev yog tsim los tsim cov qauv reticular los ntawm kev thaiv cov hlab ntsha, thiaj li ua kom cov platelets agglutinate thiab tso nyiaj fibrinogen.Qhov no yog qhov zoo heev rau kev tsim cov thrombosis, thiaj li txo tau lub sij hawm coagulation thiab thaum kawg los ntshav.Raws li nws cov txheej txheem coagulation, gelatin hemostatic daim txhuam cev muaj cov haujlwm tseem ceeb ntawm cov tshuab compression thiab dej nqus.Hauv tag nrho cov txheej txheem coagulation, piv txwv li, nws tsis ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov txheej txheem tseem ceeb hemostatic xws li kev ua kom prothrombin.Cov khoom siv absorbent gelatin daim txhuam cev siv hauv tsev kho mob muaj ntau yam tsis zoo, xws li cov tshuaj tiv thaiv loj ntawm cov ntaub so ntswg txawv teb chaws, tsis muaj hemostatic efficiency thiab yooj yim poob.Tam sim no, gelatin feem ntau hloov kho lossis sib xyaw nrog lwm cov ntaub ntawv los tsim cov ntaub ntawv hemostatic nrog kev ua haujlwm zoo.
Lwm yamAdaim ntawv thov
Gelatin feem ntau yog los ntawm collagen hauv cov ntaub so ntswg hauv lub cev, yog li nws muaj cov khoom siv lom neeg zoo heev, xws li biocompatibility zoo thiab biodegradability, yog li nws tau siv dav hauv biomedical field.Gelatin tuaj yeem siv tsis tau tsuas yog nyob rau hauv cov saum toj no, tab sis kuj nyob rau hauv kev kho mob ntawm daim tawv nqaij kab mob.Piv txwv li, hydrolyzed gelatin tuaj yeem kho cov tawv nqaij tawv, ichthyosis thiab dandruff.Ntxiv mus, gelatin kuj tau siv dav hauv cov tshuaj sab hauv.Hauv Suav Pharmacopoeia, nws tau piav qhia tias macromolecular gelatin muaj cov teebmeem ntawm moistening dryness thiab tsim cov ntshav, thiab muaj qee yam kev kho mob rau ntau yam tsos mob xws li ntshav ntshav thiab ntshav.Hydrolyzed gelatin kuj muaj cov txiaj ntsig pom tseeb hauv kev kho mob gastritis thiab lwm yam tsos mob.
