KEV THOV GELATIN HAUV COV NTAUB NTAWV BIOMEDICAL
Gelatin, ib yam khoom siv biopolymer ntuj, yog ib yam khoom noj khoom haus ntxiv uas tau npaj los ntawm kev hydrolysis nruab nrab ntawm cov pob txha tsiaj, tawv nqaij, cov leeg, cov leeg thiab cov nplai. Tsis muaj dab tsi piv rau hom khoom siv biomedical no hauv gelatin, vim nws cov biodegradability, biocompatibility zoo, gel thiab tus nqi qis. Yog li ntawd, gelatin tau siv dav ua cov tshuaj ib txwm muaj hauv cov ntaub ntawv biomedical.
NtshavScov hloov pauv
Kev hloov ntshav yog qhov tsim nyog rau ntau qhov xwm txheej, xws li kev phais ib nrab lossis kev los ntshav loj heev. Txawm li cas los xij, qhov tsis txaus ntawm cov ntshav, qhov teeb tsa ntshav nyuaj, thiab qhov kev pheej hmoo ntawm kev muab ntshav allogeneic kuj cuam tshuam rau lub sijhawm, kev ua haujlwm zoo thiab kev nyab xeeb ntawm kev kho mob mus rau qhov ntau. Txoj kev hloov plasma tuaj yeem daws cov teeb meem no, yog li nws muaj peev xwm siv tau zoo hauv kev kho mob thiab qhov chaw txhim kho kev txawj ntse. Yog li ntawd, cov ntaub ntawv gelatin, xws li succinyl gelatin thiab polygelatin peptide, yog siv dav ua cov ntshav hloov hauv chaw kho mob. Cov ntshav hloov gelatin yuav raug siv rau hauv qhov 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. Cov ntshav hloov gelatin muaj ntau qhov zoo, xws li kev puas tsuaj, kev nkag ntau, tsis muaj tshuaj lom, tsis muaj zog tiv thaiv kab mob thiab lwm yam.
Htus neeg uas muaj kev xav ntau dhauMcov khoom siv
Nyob rau xyoo tas los no, cov zej zog kho mob tau them sai sai rau kev tsim cov khoom siv hemostatic tshiab. Daim txhuam cev gelatin uas nqus tau tau nyiam ntau qhov kev saib xyuas vim nws muaj qhov zoo ntawm cov nyhuv hemostatic zoo, tus nqi qis thiab cov txheej txheem ua tau zoo. Lub tshuab hemostatic ntawm daim txhuam cev gelatin hemostatic yog feem ntau los tsim cov qauv reticular los ntawm kev thaiv cov hlab ntsha, kom cov platelets sib sau ua ke thiab tso cov fibrinogen. Qhov no muaj txiaj ntsig zoo rau kev tsim cov thrombosis, kom txo lub sijhawm coagulation thiab thaum kawg nres los ntshav. Raws li nws cov txheej txheem coagulation, daim txhuam cev gelatin hemostatic muaj cov haujlwm tseem ceeb ntawm kev sib zog thiab kev nqus dej. Hauv tag nrho cov txheej txheem coagulation, piv txwv li, nws tsis ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev tsim cov txheej txheem hemostatic tseem ceeb xws li prothrombin activation. Daim txhuam cev gelatin nqus tau uas siv hauv tsev kho mob muaj ntau qhov tsis zoo, xws li cov tshuaj tiv thaiv loj ntawm cov ntaub so ntswg txawv teb chaws, kev ua haujlwm hemostatic qis thiab yooj yim poob tawm. Tam sim no, gelatin feem ntau hloov kho lossis sib xyaw nrog lwm cov ntaub ntawv los tsim cov khoom siv hemostatic nrog kev ua tau zoo.
Lwm yamAcov ntawv thov
Gelatin feem ntau yog los ntawm collagen hauv cov nqaij ntawm lub cev, yog li nws muaj cov khoom zoo heev, xws li kev sib raug zoo thiab kev puas tsuaj ntawm cov khoom hauv lub cev, yog li nws tau siv dav hauv kev kho mob biomedical. Gelatin tsis yog siv tau rau hauv cov yam saum toj no xwb, tab sis kuj siv tau rau kev kho mob ntawm cov kab mob ntawm daim tawv nqaij. Piv txwv li, hydrolyzed gelatin tuaj yeem kho cov tawv nqaij tawg, ichthyosis thiab dandruff. Ntxiv mus, gelatin kuj tau siv dav hauv kev kho mob sab hauv. Hauv Suav Pharmacopoeia, nws tau piav qhia tias macromolecular gelatin muaj cov teebmeem ntawm kev ua kom qhuav thiab tsim cov ntshav, thiab muaj qee yam kev kho mob rau ntau yam tsos mob xws li ntshav tsis txaus thiab ntshav poob. Hydrolyzed gelatin kuj muaj cov teebmeem pom tseeb heev hauv kev kho mob gastritis ntev thiab lwm yam tsos mob.
