Ukuyeka ukubhema kungavuselela amaphaphu

-Delile

• Kwenziwa kanjani isifundo
• Okuboniswe ngucwaningo
• Yini eyayivele isaziwa

Abaphenyi e-Wellcome Sanger Institute e-College University eLondon, e-UK, benza ucwaningo nabantu ababebhema iminyaka eminingi bathola ukuthi ngemuva kokuyeka, amangqamuzana aphilile emaphashini alaba bantu ayanda, anciphisa ukulimala okudalwa ukubhema nokunciphisa izingozi zokuba nomdlavuza wamaphaphu.

Phambilini bekuvele kwaziwa ukuthi ukuyeka ukubhema kumisa ukuguqulwa kwezakhi zofuzo okubanga umdlavuza wamaphaphu, kepha lolu cwaningo olusha luletha imiphumela emihle kakhulu ekuyekeni ukubhema, kukhombisa amandla wokuvuselelwa kwamaseli wamaphaphu lapho engasadalulwanga osikilidi.

Kwenziwa kanjani isifundo

Abaphenyi baseCollege University eLondon, ababhekele isikhungo esihlola izakhi zofuzo nezofuzo lomuntu, befuna ukuqonda ukuthi kwenzakalani ngamangqamuzana amaphaphu lapho evezwa osikilidi, benze ucwaningo lapho behlaziya khona ukuguquka kwamangqamuzana ezindleleni zomoya zabantu abangu-16, phakathi kwabo bekukhona ababhemayo, ababhemayo nabantu ababengakaze babheme, kubandakanya nezingane.

Ukwenza ucwaningo luhlaziya, abacwaningi baqoqa amaseli emaphashini alaba bantu ngokwenza i-biopsy noma ukuxubha i-bronchi ekuhlolweni okubizwa nge-bronchoscopy, okuwukuhlolwa kokuhlola imigwaqo yomoya ngokwethula ithubhu eliguquguqukayo ngomlomo, bese iqinisekisa izici zofuzo ngokwenza ukulandelana kwe-DNA kwamaseli avuniwe.

Okuboniswe ngucwaningo

Ngemuva kokubheka elebhu, abacwaningi bathola ukuthi amaseli aphilile emaphashini abantu ababeseyekile ukubhema ayemakhulu ngokuphindwe kane kunalawo abantu ababesebenzisa osikilidi nsuku zonke, futhi inani lala maseli licishe lilingane nalelo elitholwa kubantu abangakaze ngabhema. ngabhema.

Ngakho-ke, imiphumela yocwaningo ikhombise ukuthi lapho engasatholakali kugwayi, amangqamuzana emaphaphu aphilile ayakwazi ukuvuselela izicubu zamaphaphu nohlaka lomoya, ngisho nakubantu ababheme iphakethe likagwayi ngosuku iminyaka engama-40. Ngaphezu kwalokho, bekukhonjwe ukuthi lokhu kuvuselelwa kwamaseli kuyakwazi ukuvikela iphaphu kumdlavuza.

Yini eyayivele isaziwa

Ucwaningo lwangaphambilini seluvele lukhombisile ukuthi ukubhema ugwayi kubanga umdlavuza wamaphaphu, njengoba kubangela ukuvuvukala, ukutheleleka futhi kunciphise ukuzivikela komzimba, okuholele ekuguqulweni kwamaseli emaphashini. Kodwa-ke, lapho uyeka ukubhema, lokhu kuguqulwa kwamaseli okuyingozi kumisiwe okwesikhashana futhi ingozi yokuba nomdlavuza wamaphaphu yehliswe kakhulu.

Le miphumela emihle yokuyeka ukubhema ibonakala cishe ngokushesha futhi ngokuthuthuka okukhulu esikhathini oyeke ngaso ukubhema, ngisho nakubantu abaneminyaka ephakathi nendawo ababhema iminyaka eminingi. Futhi lolu cwaningo olusha lwasigcizelela leso siphetho, kodwa siletha imiphumela emisha ekhuthazayo ngokubaluleka kokuyeka ukubhema, okukhombisa amandla amaphaphu okuvuselela ngokuyeka ugwayi. Bheka amathiphu wokuyeka ukubhema.
