Artificial itsvo, tariro itsva kune varwere veitsvo

Artificial itsvo uye tariro itsva, sezvatinoziva kuti inopfuura 10% yevagari vepasi vanotambura nechirwere cheitsvo, uye nyaya dziri kukurumidza kuwedzera, sezvo murwere weitsvo akakundikana anowedzerwa pamaminetsi ega ega e10, uye nhamba huru yavo inoda itsvo. transplants, maererano nehuwandu hweWorld Health Organization.

uye kuita maoparesheni mbatya Pamusoro pezvo, kushaikwa kwenhengo dzevanopa zvichienzaniswa nemazana ezviuru akanyoreswa pamazita ekumirira itsvo uye kuisirwa, kwakakurudzira boka revasayendisiti kuedza kutsvaga imwe nzira yekugadzirisa dambudziko iri kuburikidza nekugadzira itsvo yekutanga yenyika. .

Zviratidzo zvishanu zvekuti itsvo dzako dziri munjodzi

Maererano neThe Hearty Soul, William Wessel weVanderbilt University naShufu Roy weYunivhesiti yeCalifornia, San Francisco, vakatanga chirongwa che "Artificial Kidney Project" mukuedza kugadzirisa dambudziko rekushaikwa kwezvipo zveitsvo muUnited States.

Vakabudirira kugadzira itsvo inoshandisa masero eitsvo mhenyu pamwe chete nemamicrochips anofambiswa nemoyo kuti aite kushanda zvakanaka kweitsvo.

"Tinogona kutora mukana wekutsvagisa nekusimudzira kubva kuna Amai Nature nekushandisa masero eitsvo, ayo ane rombo rakanaka akakwanisa kukura zvakanaka murabhoritari, uye nekuashandura kuti ave bioreactor yemasero mapenyu," Wessel akatsanangura mune imwe nyaya yakabudiswa muKutsvakurudza. News Vanderbilt.

Idzo itsva yeitsvo yekugadzira inogona kusiyanisa nekuvimbika pakati pemarara emakemikari uye chikafu chinodiwa nemuviri wemunhu, uye kushandiswa kwayo kunongoda kuvhiyiwa kushoma kuisirwa mukati memuviri.

Basa reitsvo nderei?

Itsvo dzinoita mabasa akasiyana akakosha kuhupenyu hwemunhu, anosanganisira:

• Chengetedza kuenzana kwemvura. Itsvo inova nechokwadi chekuti plasma yeropa haina kunyanya kunyungudika kana kuderedzwa.

• Kudzora nekusefa zvicherwa kubva muropa. Kunyanya, itsvo dzine basa rekuchengetedza mazinga anogara akakosha emaminerari akadai sodium, potassium uye calcium.

• Sefa tsvina kubva muchikafu, mishonga uye zvinhu zvine chepfu. Itsvo inosefa zvinhu zvinorasa uye chepfu yezvakatipoteredza muweti kuti ibudise.

• Kugadzirwa kwemahomoni anobatsira kubudisa masero matsvuku eropa, kukurudzira utano hwemapfupa uye kugadzirisa ropa.

Kukundikana kweitsvo

Kusashanda zvakanaka kwetsvo zvinoreva kuti itsvo hadzichakwanisa kusefa tsvina kubva muropa remurwere. Mazinga ane ngozi anotanga kuungana uye magadzirirwo emakemikari emuviri anova asina kuenzana.

Hemodialysis

Dialysis ndiyo yekupedzisira kurapwa kwekutadza kweitsvo, inova nhanho apo varwere vanoisirwa itsvo seimwe sarudzo.

Nekuda kwekuti runyoro rwekumirira kuisirwa rwakareba, murwere weitsvo anotadza kuenderera mberi nedialysis vhiki nevhiki kudzamara mupi weitsvo akakodzera avepo kwaari, achirangarira kuti ongororo yake, ongororo, uye hutano hwese zvinotakura kuisirwa uye muviri wake. kukwanisa kugamuchira nhengo itsva.

Zvakanakira uye zvakaipira zve dialysis

Dialysis inogona kuita mamwe emabasa anoitwa neitsvo ine hutano, sekubvisa tsvina, munyu uye imwe mvura, kuenzanisa potassium uye sodium muropa, uye kubatsira kudzora BP.

Asi dialysis zvikamu zvinotora nguva pamwe nekuita zvinonetesa zvinowanzoitwa muchipatara kana nyanzvi nzvimbo, uye mune dzimwe nguva uye mamiriro zvinogona kuitwa kumba. Chikamu chimwe nechimwe chinotora maawa matatu kusvika mana, katatu pavhiki. Uye kusiyana nemamiriyoni ane hutano nemamiriro emuviri anobvumira kupa itsvo, kune makumi emamiriyoni achafanirwa kuita dialysis sesheni kwehupenyu hwese, aine tarisiro yehupenyu yemakore mashanu kusvika gumi.

tariro itsva

Itsvo yakagadzirwa neProject Kidney ine mamicrochips gumi nemashanu anodzorwa nemoyo uye anoita semasefa. Rabhoritari inowana masero eitsvo mhenyu kubva kumurwere uye anogadziridzwa kuti akure murabhoritari pamachip chips anotevedzera itsvo chaiyo.

Boka rekutsvagisa rinosimbisa kuti "itsvo dzekugadzira" nyowani dzichanyatsoshanda zvirinani pane dialysis sesheni uye inopa mhinduro yekusingaperi kune varwere mushure medialysis, uye zvakanyanya kushanda uye kwenguva refu kupfuura chaiyo yekuisa itsvo.

Mainjiniya parizvino vari kushanda kuyedza mativi ese emudziyo kuti vaone kushanda kwayo uye kuchengetedzeka kusati kwatanga miedzo yevanhu. Kana ikabudirira, iyo yekugadzira itsvo system inogona kubvisa kudiwa kwema dialysis masesheni kune varwere vane itsvo kutadza, kugadzirisa dambudziko rekushomeka kwenhengo dzevanopa uye kubvisa kutengeserana kwenhengo dzemunhu zvine chekuita neitsvo.
