UKUSETYENZISWA KWE-GELATIN KWIZIXHOBO ZE-BIOMEDICAL
I-Gelatin, izinto zendalo ze-biopolymer, sisongezelelo sokutya esilungiselelwe nge-hydrolysis ephakathi yamathambo ezilwanyana, izikhumba, imisipha, imisipha kunye nezikali. Akukho nto ifana nolu hlobo lwezinto ze-biomedical kwi-gelatin, ngenxa yokuba iyabola, ihambelana kakuhle ne-bio, ijeli kunye nexabiso eliphantsi. Ke ngoko, i-gelatin isetyenziswa kakhulu njengesithako seyeza lemveli kwizinto ze-biomedical.
IgaziSizithintelo
Utofelo-gazi luyimfuneko kwiimeko ezininzi, njengotyando oluncinci okanye ukopha okukhulu. Nangona kunjalo, ukunqongophala komthombo wegazi, ulwakhiwo lwegazi oluntsonkothileyo, kunye nomngcipheko wokunikezelwa kwegazi kwi-allogeneic nako kuthintela ixesha elifanelekileyo, ukusebenza kakuhle kunye nokhuseleko lonyango lweklinikhi kakhulu. Indlela yokutshintshwa kwe-plasma inokusombulula ezi ngxaki, ngoko ke inamandla amakhulu okusetyenziswa kweklinikhi kunye nendawo yokuphucula ubuchwephesha. Ke ngoko, izixhobo ze-gelatin, ezifana ne-succinyl gelatin kunye ne-polygelatin peptide, zisetyenziswa kakhulu njengezitshintshi ze-plasma eklinikhi. Izitshintshi ze-gelatin plasma ziya kusetyenziswa kwiimeko ezingxamisekileyo ezifana nokwehla komthamo wegazi kunye nomothuko. Ukungena kwe-Colloid kunokwandisa umthamo wegazi kwaye kuphucule ukuhamba kwegazi kancinci. Izitshintshi zegazi ze-gelatin zinezibonelelo ezininzi, ezifana nokubola, ukufakelwa okukhulu, ukungabi natyhefu, ukungabi namandla okuzikhusela komzimba njalo njalo.
HechukumisayoMiiteriyali
Kwiminyaka yakutshanje, uluntu lwezonyango luye lwanikela ingqalelo engakumbi kuphuhliso lwezinto ezintsha ezibangela ukonakala kwegazi. I-gelatin sponge efunxwayo iye yatsala ingqalelo enkulu kuba ineengenelo zempembelelo entle ye-hemostatic, ixabiso eliphantsi kunye nokusebenza kakuhle. Indlela ye-hemostatic ye-gelatin hemostatic sponge ikakhulu kukuvelisa isakhiwo se-reticular ngokuvala imithambo yegazi, ukuze idibanise iiplatelets kwaye ifake i-fibrinogen. Oku kuluncedo kakhulu ekwakhiweni kwe-thrombosis, ukuze kuncitshiswe ixesha lokujiya kwegazi kwaye ekugqibeleni kumiswe ukopha. Ngokwendlela yayo yokujiya kwegazi, i-gelatin hemostatic sponge inemisebenzi ephambili yokucinezelwa koomatshini kunye nokufunxwa kwamanzi. Kwinkqubo yonke yokujiya kwegazi, umzekelo, ayidlali indima ebalulekileyo ekukhuthazeni ukuveliswa kweenkqubo ezibalulekileyo ze-hemostatic ezifana nokusebenza kwe-prothrombin. I-gelatin sponge eqhelekileyo efunxwayo esetyenziswa eklinikhi ineengxaki ezininzi, ezifana nokusabela okukhulu kwemizimba yangaphandle yezicubu, ukusebenza okuphantsi kwe-hemostatic kunye nokuwa lula. Okwangoku, i-gelatin idla ngokuguqulwa okanye idityaniswe nezinye izinto ukuvelisa izinto ze-hemostatic ezisebenza kakuhle.
OkunyeAizicelo
I-Gelatin ikakhulu ivela kwi-collagen kwizicubu zomzimba, ngoko ke ineempawu ezibalaseleyo zebhayoloji, ezinje ngokuhambelana kakuhle kwezinto eziphilayo kunye nokubola kwazo, ngoko ke isetyenziswa kakhulu kwicandelo lezonyango. I-Gelatin ingasetyenziswa kungekuphela nje kwezi nkalo zingasentla, kodwa nakunyango lwezifo zesikhumba. Umzekelo, i-hydrolyzed gelatin inokunyanga ulusu oluqhekekileyo, i-ichthyosis kunye ne-dandruff. Ngaphezu koko, i-gelatin ikwasetyenziswa kakhulu kunyango lwangaphakathi. Kwi-Chinese Pharmacopoeia, kuchazwa ukuba i-macromolecular gelatin inefuthe lokufumisa ukoma kunye nokuvelisa igazi, kwaye ineziphumo ezithile zonyango kwiimpawu ezininzi ezifana ne-anemia kunye nokulahleka kwegazi. I-hydrolyzed gelatin ikwanefuthe elicacileyo kunyango lwe-gastritis engapheliyo kunye nezinye iimpawu.
