Gukomeretsa kw'imitsi ya Optic-02

Ubuvuzi bw'ingirabuzimafatizo yo gukomeretsa imitsi ya Optic: Igitangaza cyongeye kubona

Muri iki gihe tekinoloji y’ubuvuzi igenda itera imbere, indwara nyinshi zigeze gufatwa nkizitavurwa ubu zirimo kubona ibyiringiro bishya. Uyu munsi, dusangiye inkuru ikora ku mutima wa mesenchymal stem selile (MSC) ivura ibikomere byo mu mitsi ya optique, uburyo bwo kuvura buzana ibyiringiro bishya byo kubona abarwayi benshi.

Amateka ya Bwana Zhang

Bwana Zhang, ufite imyaka 47, ni injeniyeri witanze. Icyakora, ubuzima bwe bwahindutse cyane amezi ane ashize kubera impanuka ikomeye yimodoka. Muri iyo mpanuka, Bwana Zhang yangiritse cyane ku mitsi y’iburyo ya optique, bituma igabanuka ryihuse ryerekwa kugira ngo yumve neza urumuri. Nubwo yagiye avurwa gakondo hamwe na steroid n'imiti ya neurotrophique, iyerekwa rye ryerekanye iterambere rito. Iki kibazo cyaramubabaje cyane n'umuryango we.

Abisabwe n'inshuti, Bwana Zhang yamenye uburyo bwo kuvurwa - mesenchymal stem selile. Nyuma yo kugisha inama birambuye n'abaganga kabuhariwe no gusobanukirwa neza uburyo bwo kuvura, Bwana Zhang yahisemo kugerageza ubu buryo bushya.

Ingirabuzimafatizo yavuye mu maraso y’amaraso y’abakorerabushake bazima, bagenzuwe cyane kandi baragurwa mu muco kugira ubushobozi bwo kuvugurura no gusana. Bikoreshejwe binyuze mu gutera inshinge mu mitsi ya optique, utugingo ngengabuzima twagejejwe neza mu jisho ry'iburyo rya Bwana Zhang kugira ngo habeho kuvugurura imitsi yangiritse.

Gahunda yo kuvura yakorewe ahantu hadakomeye kugirango umutekano n'umutekano kuri buri ntambwe. Mu cyumweru cya mbere nyuma yo kubagwa, Bwana Zhang yagize ikibazo cyo kubyimba byoroheje no kutoroherwa aho batewe inshinge, nta bindi bimenyetso bibi. Ariko, igitangaje ni uko ukwezi kwa mbere kurangiye nyuma y’igikorwa, Bwana Zhang yatangiye kubona urumuri rudakabije kandi yashoboraga kubona urumuri rwinshi. Ihinduka ryuzuyemo ibyiringiro by'ejo hazaza.

Mu mezi yakurikiyeho, icyerekezo cya Bwana Zhang cyateye imbere buhoro buhoro. Ukwezi kwa gatatu, yashoboraga kubona urujya n'uruza rw'ibintu binini, kandi ibizamini byavutse (VEP) byerekanaga ko gukira gukomeye kwimikorere ya nervice optique. Ukwezi kwa gatandatu, ijisho rye ryiburyo ryahagaze neza kuri 0.15, bituma ashobora gutandukanya imyandikire nini nuburyo bworoshye, bizamura cyane imibereho ye ya buri munsi.

Gukira kwa Bwana Zhang ntibisobanura gusa intsinzi yubuvuzi bugezweho ahubwo binagaragaza imbaraga zihuriweho n’abashakashatsi n’ubuvuzi batabarika. Mesenchymal stem selile, binyuze mu gusohora ibintu bitandukanye bikura hamwe na cytokine, byoroheje kuvugurura no gukira kwimikorere yumutima wangiritse. Ubu buryo bwo kuvura bwerekana imbaraga zidasanzwe, butanga ibyiringiro kubarwayi benshi nka Bwana Zhang.
