Makina opanga insulin
Insulin - mahomoni apachirengedwe omwe amawongolera | chakudya kagayidwe kake komanso kukhalabe wabwinobwino wa cazdpam'magazi. Kuperewera kwa mahomoni m'thupi kumatsogolera.) Ku matenda amodzi owopsa kwambiri - matenda ashuga, omwe, monga chifukwa cha imfayo, ali m'malo wachitatu pambuyo pa matenda amtima komanso khansa. Insulin ndi globule yaying'ono | Mapuloteni okhala ndi zotsalira za 51 amino acid zomwe zimakhala ndi ma polypeptide awiri omwe amaphatikizidwa ndi milatho iwiri yopanda malire. Amapangidwa mwanjira yofanana ndi unyolo wa fetal precursor, prroinsulin, wokhala koi peptide chapakati (ma 23 amino acid zotsalira) ndi cholumikizira 35 cholumikizira (C-peptide). Peptide ya siginolo ikachotsedwa, ma proinsulin omwe amatsalira 86 amino acid amapangidwa mu khungu, momwe ma A ndi B ma insulin amalumikizidwaC-neitweed, yomwe imawapatsa iwo mawonekedwe oyenera pa $ 3 pa disulfide bond. Pambuyo pang'onopang'ono wa proteinolytic wa C peptide, insulin imapangidwa.
Mitundu ingapo ya shuga imadziwika. Mawonekedwe owopsa kwambiri, ochizira omwe wodwala amafunikira matendawa (mawonekedwe a insulin - amadalira matenda), amayamba chifukwa cha imfa yosankha maselo opanga timadzi tating'onoting'ono tomwe timapanga timadzi tating'onoting'ono tambiri tomwe timapanga ma cell a Langerhans. Mtundu wa matenda a shuga, omwe mankhwala a insulin sawafunikira, ndi ochulukirapo, ungathe kuyendetsedwa mothandizidwa ndi zakudya zoyenera ndi:> ma.

Kupeza insulin mu biotechnology
Insulin, mahomoni a peptide a zisumbu za Langerhans za kapamba, ndiye chithandizo chachikulu cha matenda ashuga. Matendawa amayamba chifukwa cha kuchepa kwa insulin ndipo amawonetsedwa ndi kuchuluka kwa shuga m'magazi. Mpaka posachedwapa, insulini idapezeka kuchokera ku zikondamoyo za ng'ombe ndi nkhumba.
Mankhwalawa anali osiyana ndi insulin ya anthu chifukwa cha m'malo mwa 1-3 amino acid, kotero kuti panali vuto la kuyanjana, makamaka kwa ana. Kugwiritsidwa ntchito kwachilengedwe kwa insulin kunali kovuta chifukwa cha mtengo wake wokwera komanso zoperewera.
Mwa kusintha kwa mankhwala, insulin kuchokera ku nyama idapangidwa kuti ikhale yosiyana ndi anthu, koma izi zimatanthawuza kukwera kwina kwa mtengo wa chinthu.
Kuyambira 1982, EliLilly wakhala akupanga ma insulin okhala ndi ma genulin malinga ndi kapangidwe ka ma CD a E. coli A ndi B. Mtengo wa malonda watsika kwambiri, chifukwa insulin yake imakhala yofanana ndi anthu. Kuyambira 1980, pakhala pali malipoti pofalitsa nkhani zokhudza kuphatikizika kwa majini a proinsulin, omwe amayendera mahomoni omwe amasintha kukhala mawonekedwe okhwima omwe alibe proteinol ochepa.
Teknoloji ya Encapsulation imagwiritsidwanso ntchito pochiza matenda ashuga: maselo a kapamba mu kapisozi, omwe amayamba kamodzi mthupi la wodwalayo, amatulutsa insulini pachaka.
Kuphatikizidwa kwa genetics kwakhazikitsa ma follicle osangalatsa komanso othandizira ma luteinizing. Izi ma peptides amapangidwa ndi ma subunits awiri. Patsikuli ndipamalo opanga ma oligopeptide mahomoni a mantha am'mimba - enkephalins, omwe amapangidwa kuchokera kutsalira la 5 amino acid, ndi endorphins, analogues of morphine.
Mukagwiritsidwa ntchito moyenera, ma peptides amachepetsa ululu, amapanga kusintha kwamphamvu, kuwonjezera mphamvu, kuyang'ana chidwi, kukonza kukumbukira, ndikuyika kugona ndikugalamuka.
Mwachitsanzo pakugwiritsa ntchito njira zopangira majini ndi kapangidwe ka p-endorphin pogwiritsa ntchito ukadaulo wa mapuloteni wosakanizidwa womwe wafotokozedwa pamwambapa kwa mahomoni ena a peptide, somatostatin.
Njira zopangira insulin yaumunthu:
Pakalembedwe, njira yoyamba yopezera insulin chifukwa cha njira zochiritsira ndikudzipatula kwa chifaniziro cha timadzi timeneti kuchokera kuzinthu zachilengedwe (ma ispancreas a kapamba a ng'ombe ndi nkhumba).
Mu 20s ya zaka zapitazi, zidapezeka kuti ma insulini a bovine ndi nkhumba (omwe ali pafupi kwambiri ndi insulin ya anthu pakupanga ndi amino acid sequence) amawonetsa zochitika mthupi la munthu poyerekeza ndi insulin yaumunthu. Pambuyo pake, insulin kapena ng'ombe ya nkhumba imagwiritsidwa ntchito pochiza odwala omwe ali ndi matenda a shuga a mtundu woyamba.
Komabe, patapita kanthawi zidawonetsedwa kuti nthawi zina ma antibodies a bovine ndi porcine insulin ayamba kudzikundikira m'thupi la munthu, potero pokana mphamvu zawo.
Kumbali inayi, chimodzi mwazabwino za njira iyi yopezera insulini ndikupezeka kwa zinthu zopangira (bovine ndi nkhumba insulin zitha kupezeka mosavuta), zomwe zidagwira ntchito yofunika pakupanga njira yoyamba yopanga insulin yaumunthu.Njira imeneyi imatchedwa semi-synthetic.
Mwanjira yopanga insulin yaumunthu, insulin ya nkhumba idagwiritsidwa ntchito ngati chakudya. C-terminal octapeptide ya B unyolo inachotsedwa ku insulin yoyesedwa, pambuyo pake C-terminal octapeptide ya insulin yaumunthu inapangidwa.
Kenako adalumikizidwa ndi mankhwala, magulu oteteza amachotsedwa ndikutsuka insulin. Poyesa njira iyi yopezera insulini, kudziwa kwathunthu momwe timadzi timene timapezera timene timapangidwa ndi insulin ya anthu timawonetsedwa.
Choyipa chachikulu cha njirayi ndi kukwera mtengo kwa insulin yomwe ikubwera (ngakhale pano, kuphatikizidwa kwa mankhwala octapeptide ndizosangalatsa mtengo, makamaka pamsika wamafuta).
Pakadali pano, insulin yaumunthu imapezeka kwambiri m'njira ziwiri: kusintha kwa insulin ndi njira yopangira-enzymatic ndi njira yothandizira majini.
Poyambirira, njirayi idakhazikitsidwa chifukwa chakuti insulini ya nkhumba imasiyana ndi insulin ya anthu m'malo mwake pa C-terminus ya Ala30Thr B unyolo.
M'malo mwa alanine ndi threonine kumachitika ndi enzyme-othandizira cleavage wa alanine ndi kuwonjezera kwa otsalira a threonine otetezedwa ndi gulu la carboxyl, lomwe limapezeka kwambiri pakuwonjezera kosakaniza. Pambuyo pokhazikika kwa gulu loteteza O-tert-butyl, insulin yaumunthu imapezeka.
Insulin anali mapuloteni oyamba omwe amapezeka kuti amagulitsidwe pogwiritsa ntchito ukadaulo wa DNA. Pali njira ziwiri zazikulu zopangira insulin yaumunthu.
Poyambirira, zophatikiza (zopangira zosiyana) zimapezeka maunyolo onse awiri, ndikutsatira mwa kupukutika kwa molekyulu (mapangidwe a milatho yopanda tanthauzo) komanso kulekanitsa ma isoforms.
Mu chachiwiri, kupanga mu mawonekedwe a precursor (proinsulin) kenako enzymatic chimbudzi ndi trypsin ndi carboxypeptidase B kupita ku mtundu wogwira wa mahomoni.
Pakadali pano, ndikofunikira kwambiri kuti mupeze insulini mwanjira yoyambira, yomwe imatsimikizira kutsekeka koyenera kwa milatho yopanda malire (munthawi yakukonzekera maunyolo, zotsatizana zamagetsi, kusiyanitsa kwa isoforms ndikukonzanso kumachitika).
Ndi njira zonsezi, ndizotheka kuti aliyense payekhapayokha kupeza zoyambira (A- ndi B-unyolo kapena proinsulin), komanso ngati gawo la mapuloteni a haibridi. Kuphatikiza pa unyolo wa A ndi B kapena proinsulin, mapuloteni a haibridi akhoza kukhala ndi:
1) onyamula mapuloteni - poperekera mapuloteni osakanizidwa kumalo opangika a khungu kapena chikhalidwe,
2) gawo loyanjana - limathandizira kwambiri kudzipatula kwa mapuloteni osakanizidwa.
Potere, zonsezi zimatha kupezeka nthawi imodzi mu kapangidwe ka mapuloteni osakanizidwa. Kuphatikiza apo, popanga mapuloteni a haibridi, mfundo zamaulidwe ochulukirapo zitha kugwiritsidwa ntchito (ndiye kuti, mapepala angapo a polypeptide omwe amapezeka amapezeka mu mapuloteni osakanizidwa), omwe angakulitse kwambiri zipatso za chandamale.

Genetic engineering insulin
Funso lazomwe insulin imapangidwira ndilothandiza osati kwa madokotala ndi akatswiri a zamankhwala okha, komanso kwa odwala matenda a shuga, komanso abale awo ndi anzawo.
Masiku ano, mahomoni apadera ndi ofunika kwambiri paumoyo wa anthu amatha kupezeka kuchokera ku zopangira zosiyanasiyana pogwiritsa ntchito matekinoloje opangidwa mwapadera komanso oyesedwa mosamala. Kutengera njira yokonzekera, mitundu yotsatirayi ya insulin imasiyanitsidwa:
- Nkhumba kapena bovine, wotchedwanso nyama
- Nkhumba yosinthidwa yazinthu ziwiri zosinthidwa
- Makina opangidwira kapena obwereza
- Kusinthidwa Mtundu
- Zopanga
Insulin ya nkhumba yagwiritsidwa ntchito kutalika kwambiri kwa matenda ashuga. Kugwiritsidwa ntchito kwake kunayambiranso zaka 20 zapitazo.
Dziwani kuti nkhumba kapena nyama ndiye chokhacho chokhacho mpaka 80s ya zaka zapitazi. Kuti mupeze, minofu ya zikondamoyo za nyama imagwiritsidwa ntchito.
Komabe, njirayi singatchulidwe kuti ndiyabwino kapena yosavuta: kugwira ntchito ndi zinthu zosaphika sikophweka nthawi zonse, ndipo zopangira palokha sizokwanira.
Kuphatikiza apo, kupezeka kwa insulin ya insulin sikugwirizana kwathunthu ndi kapangidwe ka timadzi tomwe timapangidwa ndi munthu wathanzi: zotsalira zingapo za amino acid zilipo mu kapangidwe kake. Dziwani kuti mahomoni opangidwa ndi kapamba amphaka ali ndi kusiyana kwakukulu kwambiri, komwe sikungatchulidwe chodabwitsa.
Pokonzekera izi, kuphatikiza pa zinthu zambiri zopanda michere, zomwe zimadziwika kuti proinsulin zimakhala ndi zinthu zosasinthika, chinthu chomwe sichingagawanikidwe pogwiritsa ntchito njira zamakono zodziyeretsera. Ndiye amene nthawi zambiri amakhala magwero a zovuta zina, zomwe zimakhala zowopsa kwambiri kwa ana ndi okalamba.
Mankhwala amafunanso ndalama kwa odwala matenda ashuga. Pali mankhwala anzeru amakono aku Europe, koma samangokhala chete. Izi ndi.
Pachifukwachi, asayansi padziko lonse lapansi akhala ndi chidwi chofuna kubweretsa momwe ma mahomoni opangidwa ndi nyama amagonjera kwathunthu mahomoni a pancreatic a munthu wathanzi. Kupambana kwenikweni mu pharmacology ndikuchiza matenda ashuga kunali kupanga mankhwala opangidwa ndi theka omwe amapezeka m'malo mwa amino acid alanine pokonza nyama ndi threonine.
Nthawi yomweyo, njira yopangira mahomoni ena imachokera pakukonzekera nyama. Mwanjira ina, amangosintha ndikukhala ofanana ndi mahomoni opangidwa ndi anthu. Zina mwa zabwino zawo ndikugwirizana ndi thupi la munthu komanso kusapezeka kwa zinthu zina zonse.
Zoyipa za njirayi zimaphatikizaponso kuperewera kwa zinthu zopanda pake ndi zovuta zogwira ntchito ndi zinthu zachilengedwe, komanso mtengo wokwera waukadaulo womwewo komanso mankhwala omwe amapezeka.
Motere, mankhwala abwino kwambiri ochizira matenda a shuga ndi omwe amapanganso insulin yomwe imapezeka ndi ma genetic engineering.
Zodabwitsa ndizakuti, nthawi zambiri zimatchedwa kuti insulin yopangidwa kuchokera ku chibadwa, motero zimawonetsera njira yopezera, ndipo chotsatira chake chimatchedwa insulin ya munthu, potero chikugogomezera kudziwikiratu kwake kwa mahomoni opangidwa ndi kapamba wa munthu wathanzi.
Mwa zabwino za genulin engineering insulin, munthu ayenera kuzindikira kuyera kwake kokwanira komanso kusowa kwa proinsulin, komanso kuti siyambitsa zomwe sizingachitike ndipo alibe zotsutsana.
Funso lomwe limafunsidwa pafupipafupi ndikomveka: kodi insulini yopangidwanso ndi iti? Ndikusintha kuti timadzi timeneti timapangidwa ndi yisiti tizilombo, komanso Escherichia coli, woyikidwa mu sing'anga wapadera wa michere. Kuphatikiza apo, kuchuluka kwa zinthu zomwe zapezeka ndizambiri kwambiri kotero kuti ndizotheka kusiya kugwiritsa ntchito mankhwala omwe amapezeka kuchokera ku ziwalo za nyama.
Zachidziwikire, izi sizokhudza a E. coli osavuta, koma za mtundu wosinthika komanso wokhoza kutulutsa insulin yaumunthu yopanga majini, kapangidwe ndi mawonekedwe ake omwe ali ofanana ndendende ndi mahomoni opangidwa ndi maselo a kapamba a munthu wathanzi.
Ubwino wa genetic engineering insulin sikufanana kwawo kofanana ndi mahomoni amunthu, komanso mwayi wokonzekera, kuchuluka kwakakwanira kwa zinthu zopangira komanso mtengo wotsika mtengo.
Asayansi kuzungulira padziko lonse lapansi akuti kupanga insulini yothandizanso kupindulitsa kwa matenda ashuga. Tanthauzo la zomwe apezazi ndizabwino kwambiri ndipo nkofunika kuti kuzidalira.
Ndizosavuta kuzindikira kuti lero pafupifupi 95% ya kufunika kwa timadzi timeneti imakwaniritsidwa mothandizidwa ndi insulin.
Nthawi yomweyo, anthu masauzande ambiri omwe kale anali ndi mankhwala osokoneza bongo adalandira mwayi wokhala ndi moyo wabwinobwino.
Ndinadwala matenda ashuga kwa zaka 31. Tsopano ali wathanzi. Koma, makapisozi awa ndi osatheka ndi anthu wamba, safuna kugulitsa mankhwala, sizopindulitsa kwa iwo.
Momwe insulin yolumikizira anthu imagwirira ntchito
Mankhwalawa amachokera ku mtundu woyamba wa matenda a shuga 1, umagwiritsa ntchito mitundu iwiri yama cell insulin. M'mafakisi, amagulitsidwa monga yankho ndipo ali ndi "Wokondedwa". Mtundu wachiwiri wa matenda amathanso kuthandizidwa ndi mankhwalawa ngati mankhwala omwe sanayenere kudwala matenda ashuga.
Insulin yopangidwa ndi chibadwa imagwiritsidwanso ntchito ngati munthu akudwala matenda a shuga. Madokotala nthawi zambiri amapereka ma jakisoni kwa amayi apakati omwe amapezeka ndi matenda osokoneza bongo pamene mapiritsi ochepetsa shuga komanso zakudya zochizira sizithandiza.
Mwambiri, ma insulin omwe amapanga ma genetically kapena ma GMO amagwiritsidwa ntchito pakubala, akamachitidwa opaleshoni, kapena ngati wodwalayo wavulala kwambiri. Mankhwala amakulolani kuti musinthe moyenera kugwiritsa ntchito mahomoni ochita zinthu mwachangu.
- Musanagwiritse ntchito zomangira zamtundu wa insulin biphasic, ndikofunikira kuyesa ndikuwona ngati mankhwalawa ndi oyenera kwa wodwala. Ngati wodwala matenda ashuga aulula hypoglycemia, kugwiritsa ntchito mankhwalawa osavomerezeka.
- Chiwembu chogwira ntchito yothetsera vutoli ndikuti ma insulin omwe amapangidwa ndi majini amayanjana ndi maselo, zomwe zimabweretsa mapangidwe. Maselo akalowa izi, amakondoweza ndikuyamba kugwira ntchito molimbika. Zotsatira zake, ma enzyme ochulukirapo amapangidwa.
- Mukuchita izi, glucose amalowetsedwa mwachangu, michere yomwe imalowa m'thupi imakonzedwa mwachangu. Chifukwa chake, chiwindi chimapanga shuga yayitali, ndipo mapuloteni amatha kuyamwa mwachangu kwambiri.
Upangiri wokhudzana ndi mankhwalawa umatengera mlingo, mtundu wa insulin, kusankha kwa jekeseni. Njira iliyonse iyenera kuchitidwa pokhapokha povomerezana ndi adokotala. Jakisoni woyamba amachitika moyang'aniridwa ndi achipatala.

Zimathandizira kuchepetsa kuchuluka kwa shuga chifukwa chakuti glucose amatengeka kwambiri ndi maselo, ndi machitidwe a kayendedwe kake. Koma mankhwalawa amafunika kugwiritsidwa ntchito mosamala malinga ndi zomwe dokotala wakupatsani, chifukwa zimatha kuyambitsa mavuto osafunikira kwa wodwala. Insulin ndiye mankhwala othandizira matenda a shuga a mtundu woyamba. Nthawi zina amagwiritsidwanso ntchito kukhazika mtima pansi wodwalayo ndikuwongolera moyo wake wamtundu wachiwiri wa matenda. Izi ndi chilengedwe chake ndi mahomoni omwe amatha kuthana ndi kagayidwe kazachilengedwe mu milingo yaying'ono. Nthawi zambiri, kapamba amapanga insulin yokwanira, yomwe imathandizira kukhala ndi shuga m'thupi. Koma ndi zovuta zazikulu za endocrine, mwayi wokhawo wothandiza wodwala nthawi zambiri ndi jakisoni wa insulin kwenikweni. Tsoka ilo, ndizosatheka kuzipeza pakamwa (mwanjira yamapiritsi), popeza zimawonongeka kwathunthu m'mimba ndikugaya mtengo wake wachilengedwe. Kulandila timadzi ta nkhanu ndi ng'ombe ndi ukadaulo wakale womwe sugwiritsidwa ntchito masiku ano. Izi zimachitika chifukwa cha mankhwala ochepa omwe adalandiridwa, zomwe zimapangitsa kuti pakhale zovuta zina komanso kuyeretsa kosakwanira. Chowonadi ndi chakuti popeza mahomoni ali ndi mapuloteni, amakhala ndi ma amino acid ena. Insulin yomwe imapangidwa mthupi la nkhumba imasiyana mu ma amino acid omwe amapangidwa ndi insulin yaumunthu 1 amino acid, ndi bovine insulin ndi 3. Kumayambiriro ndi pakati pa zaka za zana la 20, pamene mankhwala ofananawo analibe, ngakhale insulin yotereyi inali yopambana pamankhwala ndikulola kutenga chithandizo cha odwala matenda ashuga kupita nawo kumalo ena atsopano. Ma Horoni omwe adapangidwa ndi njirayi amachepetsa shuga m'magazi, komabe, nthawi zambiri ankayambitsa zovuta komanso chifuwa. Kusiyana pakapangidwe ka amino acid ndi zosafunikira zakumwa zimakhudza mkhalidwe wa odwala, makamaka m'magulu omwe ali pachiwopsezo cha odwala (ana ndi okalamba). Chifukwa china chosalolera bwino insulin yotereyi ndi kupezeka kwa kuyamwa kwa mankhwala osagwiritsa ntchito (proinsulin), komwe sikunali kotheka kuti athetse kusiyanasiyana kwa mankhwalawa. Masiku ano, pali ma insuge apamwamba apamwamba omwe alibe zoperewera. Zimapezeka kuchokera kapamba wa nkhumba, koma zitatha zimayatsidwa ndikuwonjezera kuyeretsa. Zili ndi mitundu yambiri ndipo zimakhala ndi zotuluka. Insulin ya nkhumba yosinthidwa sikuti imasiyana ndi mahomoni amunthu, chifukwa chake imagwiritsidwabe ntchito Mankhwalawa amaloledwa ndi odwala bwino ndipo samayambitsa mavuto, samachepetsa chitetezo cha mthupi ndipo amachepetsa shuga la magazi. Bovine insulin sikugwiritsidwa ntchito ngati mankhwala masiku ano, chifukwa chifukwa chakunja kwake kumakhudza chitetezo chathupi komanso machitidwe ena a thupi. Insulin yaumunthu, yomwe imagwiritsidwa ntchito ngati odwala matenda ashuga, pamsika wamafuta amapezeka m'njira ziwiri: Zosungidwa za insulinZizindikiro ndi contraindication
Pharmacological zochita za mankhwala
Zitsanzo za Mankhwala Otenga Majini a Genetically
Kodi insulin imapangidwa kuchokera ku chiyani?
Zokonzekera zomwe zimapezeka kuchokera ku zopangira zachilengedwe
Katswiri wa Majini a Insulin
Ndi kusintha kwa mankhwala a physico-cell, mamolekyulu a porcine insulin pansi pa michere yapadera amakhala ofanana ndi insulin yaumunthu. Kapangidwe ka amino acid kamakonzedwe kotsatira sikusiyana ndi kapangidwe kazinthu zachilengedwe zomwe zimapangidwa m'thupi la munthu.
Pakupanga, mankhwalawa amatsukidwa kwambiri, chifukwa chake sizoyambitsa thupi kapena mawonekedwe ena osayenera.
Koma nthawi zambiri, insulin imapezeka pogwiritsa ntchito mitundu yosinthika (genetically modified). Pogwiritsa ntchito njira za biotechnological, mabakiteriya kapena yisiti amasinthidwa m'njira yoti iwonso atulutse insulin.
Kuphatikiza pakupanga insulin yokha, kuyeretsedwa kwake kumachita mbali yofunika. Kuti mankhwalawa asayambitse zovuta zilizonse komanso zotupa, pagawo lililonse ndikofunikira kuyang'anira kuyera kwa zovuta za michere ndi zothetsera zonse, komanso zosakaniza zomwe zimagwiritsidwa ntchito.
Pali njira ziwiri zopangira insulin. Yoyamba mwa izo idakhazikitsidwa ndikugwiritsa ntchito mitundu iwiri yosiyanasiyana.
Iliyonse imapangika gawo limodzi lokha la mamolekyule a ma DNA (pali awiri okha, ndipo amapindika molunjika).
Kenako maunyolo awa amalumikizidwa, ndipo mu njira yotsatila ndikothekanso kupatulira mitundu yogwira insulin kwa iwo omwe alibe phindu lililonse kwachilengedwe.
Njira yachiwiri yomwe mungalandire mankhwalawa pogwiritsa ntchito Escherichia coli kapena yisiti zimatengera kuti microbe yoyamba imapanga insulin (ndiye kuti, omwe adalowetsa kale, proinsulin). Kenako, pogwiritsa ntchito enzymatic chithandizo, fomu iyi imayatsidwa ndikugwiritsidwa ntchito ngati mankhwala.
Ogwira ntchito omwe ali ndi mwayi wopezeka m'malo ena opanga zovala ayenera kuvala suti yodzitetezera, yomwe imachotsa kulumikizana ndi mankhwalawa ndi madzi amthupi la anthu.
Njira zonsezi nthawi zambiri zimakhala zamagalimoto, mpweya ndi mawonekedwe onse polumikizana ndi ma ampoules ndi mbale sizowoneka bwino, ndipo mizere yokhala ndi zida ndiyosindikiza.
Njira za biotechnology zimathandizira asayansi kuti aganizire njira zina zothanirana ndi shuga.
Mwachitsanzo, pakadali pano, maphunziro oyamba opanga ma cell a pancreatic beta akuchitika, omwe amatha kupezeka pogwiritsa ntchito njira zopangira majini.
Mwina m'tsogolomu adzagwiritsidwa ntchito kukonza zomwe zimachitika m'thupi mwa wodwala.
Kupanga kwamankhwala amakono a insulin ndi njira yovuta yaukadaulo yomwe imaphatikizapo magalimoto ndi kulowererapo pang'ono kwa anthu
Zowonjezera zina
Kupanga kwa insulin popanda maipi mu masiku amakono kuli kosatheka kulingalira, chifukwa amatha kusintha zinthu zake zamankhwala, kuwonjezera nthawi yanthawi ndikukwaniritsa kuyera kambiri.
Mwa zomwe ali nazo, zosakaniza zina zonse zitha kugawidwa m'magulu otsatirawa:
- prolongators (zinthu zomwe zimagwiritsidwa ntchito popereka nthawi yayitali ya mankhwala),
- mankhwala ophera tizilombo toyambitsa matenda
- olimbitsa, chifukwa chomwe acidity yoyenera imasungidwa mu yankho la mankhwalawa.
Kupitiliza Zowonjezera
Pali ma insulin omwe amagwira ntchito kwa nthawi yayitali omwe zochita zake zimakhala kwa maola 8 mpaka 42 (kutengera gulu la mankhwalawo). Izi zimatheka chifukwa cha kuwonjezera pa zinthu zapadera - zotambuzira ku yankho la jakisoni. Nthawi zambiri, imodzi mwamafuta awa imagwiritsidwa ntchito pazolinga izi:
Mapuloteni omwe amalimbitsa nthawi ya mankhwalawa amayeretsedwa mwatsatanetsatane ndipo amakhala otsika pang'ono (mwachitsanzo, protamine). Mchere wamchere wa zinc sukhudzanso zochita za insulin kapena thanzi la munthu.
Tizilombo toyambitsa matenda tomwe timapangira insulini ndikofunikira kuti tizilombo tating'onoting'ono tisachulukane panthawi yosungirako ndikugwiritsa ntchito momwemo. Zinthu izi ndizosungirako komanso kuonetsetsa kuti mankhwalawo amasungidwa.
Kuphatikiza apo, ngati wodwala amapereka mahandawo kuchokera kwa iye yekha, ndiye kuti mankhwalawo amatha kwa masiku angapo.
Chifukwa cha ma antibacterial apamwamba kwambiri, sangakhale ndi mwayi wotaya mankhwala osagwiritsidwa ntchito chifukwa choganiza kuti zitha kubereka mwanjira yankho la ma virus.
Zinthu zotsatirazi zitha kugwiritsidwa ntchito ngati mankhwala ophera majeremusi popanga insulin:
Ngati yankho lake lili ndi ayoni a zinc, amakhalanso ngati chosungirako chifukwa cha antimicrobial
Popanga mtundu uliwonse wa insulini, zinthu zina zoyambitsa matenda zimakhala zoyenera. Kuchita kwawo ndi mahomoni kuyenera kufufuzidwa pamlingo woyeserera koyambirira, popeza osungirako sayenera kusokoneza zochita za insulin kapena kusokoneza katundu wake.
Kugwiritsira ntchito mankhwala osungirako nthawi zambiri kumapangitsa kuti timadzi timadzi timene timatulutsa pakhungu popanda kulandira mankhwala asanachitike ndi mowa kapena antiseptics (wopanga nthawi zambiri amatanthauza izi pamalangizo).
Izi zimathandizira kukhazikitsa kwa mankhwalawa ndikuchepetsa kuchuluka kwa mankhwalawa pokonzekera jakisoni wokha.
Koma malingaliro awa amangogwira ntchito ngati yankho limaperekedwa pogwiritsa ntchito syringe imodzi ya insulini ndi singano yopyapyala.
Olimbitsa
Olimba amafunika kuti pH yothetsera vutoli ikhalebe yokhazikika. Kusungidwa kwa mankhwalawa, ntchito zake ndi kukhazikika kwa katundu wamafuta zimadalira kuchuluka kwa acidity. Popanga mahomoni a jakisoni kwa odwala matenda ashuga, ma phosphates nthawi zambiri amagwiritsidwa ntchito pazolinga izi.
Kwa insulin yokhala ndi zinc, njira zothetsera kukhazikika sizofunikira nthawi zonse, chifukwa zitsulo zazitsulo zimathandizira kukhalabe koyenera.
Ngati agwiritsidwa ntchito, ndiye kuti mitundu ina ya mankhwala imagwiritsidwa ntchito m'malo mwa phosphates, popeza kuphatikiza kwa zinthu izi kumabweretsa kupendekera ndi kusafunika kwa mankhwalawo.
Chuma chofunikira chomwe chikuwonetsedwa kwa okhazikika onse ndi chitetezo ndi kulephera kulowa pazosintha zilizonse ndi insulin.
A endocrinologist wokhoza bwino ayenera kuthana ndi kusankha kwa majakisoni obwera ndi shuga kwa wodwala aliyense payekhapayekha.
Ntchito ya insulin sikuti kungokhala ndi shuga wambiri m'magazi, komanso osati kuvulaza ziwalo zina ndi machitidwe ena. Mankhwalawa ayenera kukhala osalowerera m'thupi, otsika pang'ono komanso oyenera kugula.
Ndiwothekanso kosavuta ngati insulin yosankhidwa ikhoza kusakanizidwa ndi mitundu yake ina kutengera nthawi yochitapo kanthu.
