UBaltimore Owesifazane Ongakaze Afe
,,,01,,, UBaltimore Owesifazane Ongakaze Afe
,,,01,,, Konke kwaqala ngoFebhuwari 1951
emnyangweni wezocwaningo ngesiko lezicubu zomuntu
esibhedlela iJohn Hopkins eBaltimore, e-United States.
Uprofesa ophethe le nsizakalo nguDokotela George Otto Gey.
Ngomkakhe, bazame iminyaka engaphezu kwengu-20,
ngeze, ukugcina amangqamuzana omdlavuza kumasiko ukuze ukwazi ukuwafunda.
Umsebenzi awunakwenzeka, ngenxa yenani eliphansi lezigaba,
ulayini weseli ukhule ngaphandle komzimba womuntu
kugcine kucime ukuphelelwa yithemba kwalezi zithandani zocwaningo.
Egumbini elisesibhedlela iHopkins eligcinelwe abamnyama
(siphakathi kokubandlululwa ngokohlanga e-USA),
sethula uProfesa Gey umama osemncane
Oneminyaka engu-31 oza kokwelapha
kutholakale isimila esibi emlomo wesibeletho ezinsukwini eziyisishiyagalombili ngaphambili.
Uyelashwa, njengabo bonke abagulayo besikhathi,
radium. Udokotela wezifo zabesifazane omlandelayo uyathatha
isampula lesimila sakhe asitshengise uDkt Gey.
Lesi sakamuva sihlaziya amangqamuzana omdlavuza
eqoqwe abese enza ukutholwa okungavamile.
Akugcini nje ngokungafi, kepha kuyanda ngaphandle komkhawulo.
Ubukhona be-enzyme ethile
kumaseli weHenrietta Kushoda,
futhi engatholakalanga kwenye indawo,
okusheshisa ukwanda okungalawuleki
ngokwehlukana okulandelanayo. Lokhu kutholakala
kwaba nesithakazelo esikhulu kuGeorge Otto Gey
ngoba akakwazanga ukulima kuphela
amaseli womuntu ku-vitro, kodwa futhi
usabalalise kwamanye amalebhu.
Babizwa ngokuthi amaseli we-HeLa (we-Henrietta Lacks).
Lo mugqa weseli uthi,
okwamanje,
umugqa ojwayelekile wazo zonke izifundo zomdlavuza
kanye neseli biology eyenziwa kumaseli womuntu.
Ngakho-ke bonke ososayensi basebenza nala maseli,
kusuka emzimbeni kaHenrietta Kushoda.
Bazobe sebenze ukuhlala esikhaleni
ukuthola ukuthi amangqamuzana omuntu angaphila yini lapho amandla adonsela phansi engekho.
Namuhla, inombolo yamanje yamaseli we-HeLa ayatholakala
emhlabeni wonke kudlula inani lamaseli akhona emzimbeni womuntu
(cishe amaseli ayikhulu lama-trillion kumuntu omdala).
Uzoqonda, lawa amaseli we-Henrietta Lacks
asebengabokungafi hhayi yena.
Ngoba uma amaseli akhe ayekhula ngesivinini esigcwele
kumashubhu okuhlola, nawo enza okufanayo emzimbeni wakhe.
UHenrietta ushone ngo-Okthoba 5, 1951 ebulawa ngumdlavuza ojwayelekile.
Kepha le ndaba ayigcini lapho futhi iveza abaningi
imibuzo yokuziphatha eqala ngeqiniso
ukuthi amaseli aqoqwe ekuqaleni
ngaphandle kwemvume yesiguli noma umndeni wakhe.
Ngemuva kwalokho, futhi noma ngabe wonke umuntu angaba nakho
kuleli phuzu impendulo yomuntu uqobo,
umuntu angazibuza ukuthi amaseli athathwe kumuntu,
futhi okuqukethe i-DNA yakhe, okuhlala kungokwakhe ngemuva kokuhlolwa komzimba?
Umbuzo wabuzwa eNkantolo Ephakeme YaseCalifornia
ngubani owahlulela ukuthi lokhu bekungenjalo nokuthi ngalokho
Amaseli kaHenrietta Ukuntuleka angakwazi
zisatshalaliswe ngokukhululekile futhi zimakethwe.
I-herietta enjalo ezosala kimi i-post mortem
nakanjani iyoba le bhulogi
Ukuphela kwento ezohlala ngaphambili
leyo khompyutha ne-intanethi ngokulandelayo kuyafa.
Kunoma ikuphi, uma uzizwa ungangabazi ukwabelana ngale ndatshana
ukugcina le bhulogi iphila, Ngiyabonga ngokungifundela ukwanga okukhulu.
