Ukulimala Kwezinzwa Zokubona-03

Ukuthola Umbono Obusha Ngokujova Iso Le-Stem Cell Posterior Eye Ukulimala Kwe-Optic Nerve

Ukulimala kwemizwa yamehlo sekuyisikhathi eside kuyinselele emkhakheni wezokwelapha, kodwa ngentuthuko eqhubekayo yokwelashwa ngamaseli e-stem, iziguli eziningi zithola ithemba elisha. Namuhla, sabelana ngendaba ekhuthazayo yesiguli, uNkk. Wang, esaphinde sabona ngokujova iso ngemuva kweseli le-stem.

UNkk. Wang, oneminyaka engu-42 ubudala, unguthisha. Eminyakeni emibili edlule, walimala kakhulu ebuchosheni okwabangela ukulimala kwenzwa yakhe yokubona yangakwesokudla, okwabangela ukwehla okusheshayo kokubona kanye nokulahlekelwa cishe ngokuphelele kokubona esweni lakhe lokunene. Ukulahlekelwa umbono isikhathi eside akuthintanga nje kuphela umsebenzi wakhe kanye nokuphila kwansuku zonke kodwa futhi kwamfaka ekucindezelekeni okukhulu.

Ngemva kokuzama izindlela ezahlukene zokwelapha zendabuko kodwa kungaphumeleli, udokotela owayemnakekela uNkk. Wang wamsikisela ukuthi azame ukwelashwa okusha—umjovo wamehlo ongemuva we-stem cell. Ngemva kokubonisana okuningiliziwe nokuqonda inqubo yokwelashwa, uNkk. Wang wanquma ukwenza lokhu kwelashwa okusha, enethemba lokubuyisela umbono wakhe.

Ngaphambi kokuqhubeka nokwelashwa, uNkk. Wang wahlolwa ngokuphelele, okuhlanganisa ukuhlolwa kokubona, ukuhlolwa kwe-fundus, ukuthwebula izithombe zemizwa yamehlo, kanye nokuhlolwa kwempilo iyonke. Lokhu kuhlolwa kwaqinisekisa ukuthi isimo sakhe somzimba siyafaneleka ekwelashweni kwamaseli e-stem futhi kwanikeza isisekelo sesayensi sokuthuthukisa uhlelo lokwelashwa oluqondene nomuntu siqu.

Lapho sekuqinisekisiwe ukuthi uNkk. Wang wayefanelekela ukuhlinzwa, ithimba lezokwelapha laklama uhlelo lokuhlinzwa olunemininingwane. Ngaphansi kokuhlinzwa kwendawo, ukuhlinzwa kwakuhilela amasu angangenisi kakhulu ukufaka amaseli okuqala engxenyeni engemuva yeso, eduze nendawo ye-optic nerve. Yonke inqubo yathatha cishe ihora, lapho uNkk. Wang azizwa khona ubuhlungu obuncane. Odokotela baqondisa ukujova okunembile kwamaseli okuqala besebenzisa izithombe zesikhathi sangempela ukuqinisekisa ukuthi afinyelela endaweni eqondiwe ngokunembile.

Ngemva kokuhlinzwa, uNkk. Wang waqashwa egumbini lokululama amahora amaningana. Odokotela baklama uhlelo oluphelele lokunakekelwa ngemva kokuhlinzwa, okuhlanganisa ukusetshenziswa kwama-antibiotic kanye nemithi yokulwa nokuvuvukala, ukuhlolwa kwamehlo njalo, kanye nochungechunge lwezivivinyo zokuvuselela. Ekupheleni kwesonto lokuqala ngemva kokuhlinzwa, uNkk. Wang waqala ukubona ukukhanya okuncane esweni lakhe lokunene, intuthuko encane eyamjabulisa yena nomndeni wakhe.

Ezinyangeni ezimbalwa ezalandela, uNkk. Wang wayeya njalo ezibhedlela futhi wahlanganyela ekuqeqeshweni kokuvuselelwa. Umbono wakhe wathuthuka kancane kancane, ethuthuka kusukela ekuboneni ukukhanya ekuqaleni waze wakwazi ukubona izinhlaka zezinto ezilula futhi ekugcineni waqonda imininingwane ngaphakathi kwebanga elithile. Ezinyangeni eziyisithupha kamuva, umbono kaNkk. Wang esweni lakhe lokunene wawusuthuthuke waba ngu-0.3, okwaphawula ukuthuthuka okukhulu kwekhwalithi yempilo yakhe. Wabuyela endaweni yesikhulumi, eqhubeka nomsebenzi wakhe owuthandayo kwezemfundo.

Icala eliphumelele likaNkk. Wang libonisa amandla amakhulu okufakwa kweso ngemuva kwe-stem cell ekwelapheni ukulimala kwe-optic nerve. Lokhu kwelashwa okusha akulethi nje ithemba elisha ezigulini ezilimale kwi-optic nerve kodwa futhi kunikeza idatha yezokwelapha ebalulekile yocwaningo lwezokwelapha. Sikholelwa ukuthi ngokuqhubeka kwentuthuko kwezobuchwepheshe besayensi, iziguli eziningi ezilimale kwi-optic nerve zizophinde zibone ngalokhu kwelashwa, zamukele ubuhle bempilo futhi.
