Kugwiritsa ntchito gelatin mu zinthu zopangidwa ndi biomedical
Gelatin, chinthu chachilengedwe cha biopolymer, ndi chowonjezera cha chakudya chopangidwa ndi hydrolysis yocheperako ya mafupa, zikopa, minyewa, minyewa ndi mamba a nyama. Palibe chofanana ndi mtundu uwu wa zinthu zamankhwala zomwe zili mu gelatin, chifukwa cha kuwonongeka kwake, kuyanjana bwino ndi thupi, gel komanso mtengo wotsika. Chifukwa chake, gelatin yagwiritsidwa ntchito kwambiri ngati chowonjezera chamankhwala chachikhalidwe muzinthu zamankhwala.

Kuika magazi m'magazi n'kofunika nthawi zambiri, monga opaleshoni yochepa kapena kutuluka magazi ambiri. Komabe, kusowa kwa magazi, kapangidwe ka magazi kovuta, komanso chiopsezo cha magazi opangidwa ndi allogeneic kumalepheretsa nthawi, kugwira ntchito bwino, komanso chitetezo cha chithandizo chachipatala. Njira yosinthira plasma imatha kuthetsa mavutowa, kotero ili ndi mwayi waukulu wogwiritsa ntchito kuchipatala komanso malo owongolera ukadaulo. Chifukwa chake, zinthu za gelatin, monga succinyl gelatin ndi polygelatin peptide, zimagwiritsidwa ntchito kwambiri ngati zolowa m'malo mwa plasma m'chipatala. Zolowa m'malo mwa gelatin plasma zidzagwiritsidwa ntchito pazidzidzidzi monga kuchepa kwa magazi ndi kugwedezeka. Kulowa kwa Colloid kumatha kukulitsa kuchuluka kwa magazi ndikuwonjezera kuyenda kwa magazi m'magazi. Zolowa m'malo mwa Gelatin m'magazi zili ndi zabwino zambiri, monga kuwonongeka, kulowetsedwa kwakukulu, zopanda poizoni, zopanda chitetezo chamthupi ndi zina zotero.

M'zaka zaposachedwapa, gulu lachipatala lakhala likuyang'ana kwambiri pakupanga zinthu zatsopano zoyeretsera magazi. Siponji ya gelatin yomwe imayamwa yakopa chidwi chachikulu chifukwa ili ndi ubwino wokhala ndi zotsatira zabwino zoyeretsera magazi, mtengo wotsika komanso kuthekera kogwira ntchito mwamphamvu. Njira yoyeretsera magazi ya siponji ya hemostatic ya gelatin makamaka imapanga mawonekedwe a reticular mwa kutseka mitsempha yamagazi, kuti igwirizanitse ma platelet ndikuyika fibrinogen. Izi ndizothandiza kwambiri pakupanga thrombosis, kuti achepetse nthawi yoyeretsera magazi ndikusiya kutuluka magazi. Malinga ndi njira yake yoyeretsera magazi, siponji ya hemostatic ya gelatin ili ndi ntchito yofunika kwambiri yokakamiza makina ndi kuyamwa madzi. Mwachitsanzo, mu njira yonse yoyeretsera magazi, sichita gawo lofunika kwambiri pakulimbikitsa kupanga njira zofunika zoyeretsera magazi monga kuyambitsa prothrombin. Siponji ya gelatin yomwe imagwiritsidwa ntchito kuchipatala ili ndi zovuta zambiri, monga momwe minofu yakunja imachitira, kuchepa kwa hemostatic bwino komanso kusweka mosavuta. Pakadali pano, gelatin nthawi zambiri imasinthidwa kapena kuwonjezeredwa ndi zinthu zina kuti ipange zinthu zoyeretsera magazi zomwe zimagwira ntchito bwino.

Gelatin imachokera makamaka ku collagen m'thupi, kotero ili ndi zinthu zabwino kwambiri zamoyo, monga kuyanjana bwino ndi thupi komanso kuwonongeka kwa thupi, kotero yagwiritsidwa ntchito kwambiri m'munda wa zamankhwala. Gelatin ingagwiritsidwe ntchito osati pazinthu zomwe zili pamwambapa zokha, komanso pochiza matenda a khungu. Mwachitsanzo, gelatin yothira madzi imatha kuchiza khungu losweka, ichthyosis ndi dandruff. Kuphatikiza apo, gelatin yagwiritsidwanso ntchito kwambiri mu mankhwala amkati. Mu Chinese Pharmacopoeia, zafotokozedwa kuti gelatin ya macromolecular imakhala ndi mphamvu yonyowetsa kuuma ndikupanga magazi, ndipo imakhala ndi zotsatira zina zochiritsa pazizindikiro zambiri monga kuchepa kwa magazi ndi kutaya magazi. Gelatin yothira madzi imakhalanso ndi zotsatira zoonekeratu pochiza gastritis yosatha ndi zizindikiro zina.
