Kusiya kusuta kumatha kupatsanso mapapu

Zamkati

• Momwe phunziroli lidachitikira
• Zomwe kafukufukuyu adawonetsa
• Zomwe zinali zodziwika kale

Ofufuza ku Wellcome Sanger Institute ku University University ku London, UK, adachita kafukufuku ndi anthu omwe amasuta kwa zaka zambiri ndipo atapeza kuti atasiya, maselo athanzi m'mapapu a anthuwa adachulukana, ndikuchepetsa kuvulala komwe kumadza chifukwa cha kusuta komanso kuchepetsa kuopsa kokhala ndi khansa yamapapo.

Poyamba, zinali kudziwika kale kuti kusiya kusuta kumayimitsa kusintha kwa majini komwe kumayambitsa khansa yam'mapapo, koma kafukufuku watsopanoyu amabweretsa zotsatira zabwino pakuletsa kusuta, kuwonetsa mphamvu yakukonzanso kwamaselo am'mapapo atapanda kusuta ndudu.

Momwe phunziroli lidachitikira

Ofufuza ku Yunivesite ya College ku London, omwe amayang'anira sukulu yomwe imafufuza za majini ndi majini a anthu, pofuna kudziwa zomwe zimachitika m'maselo am'mapapo mukakumana ndi ndudu, adachita kafukufuku yemwe adasanthula kusintha kwa ma cell mu mayendedwe a anthu a 16, mwa iwo panali omwe amasuta, omwe amasuta kale komanso anthu omwe samasuta, kuphatikiza ana.

Pofufuza kafukufukuyu, ofufuzawo adatolera maselo m'mapapu a anthu awa pochita biopsy kapena kutsuka bronchi pakuwunika komwe kumatchedwa bronchoscopy, komwe kumayesa kuwunika mayendedwe apweya poyambitsa chubu chosinthasintha pakamwa, kenako ndikutsimikizira mawonekedwe amtunduwu pochita kusanja kwa DNA kwa maselo omwe adakololedwa.

Zomwe kafukufukuyu adawonetsa

Atawunika ma labotale, ofufuzawo adapeza kuti maselo athanzi m'mapapu a anthu omwe asiya kusuta amakhala akulu kuposa kanayi kuposa anthu omwe amagwiritsabe ntchito ndudu tsiku lililonse, ndipo kuchuluka kwa maselowa kunali pafupifupi kofanana ndi omwe amapezeka mwa anthu omwe kusuta fodya

Chifukwa chake, zotsatira za kafukufukuyu zidawonetsa kuti ngati sakuwonetsanso fodya, maselo am'mapapo athanzi amatha kukonzanso minofu yam'mapapo ndi njira zoyendetsera ndege, ngakhale mwa anthu omwe asuta paketi ya ndudu tsiku lililonse kwazaka 40. Kuphatikiza apo, zinali zotheka kuzindikira kuti kusinthidwa kwa khungu uku kumatha kuteteza mapapu ku khansa.

Zomwe zinali zodziwika kale

Kafukufuku wam'mbuyomu adawonetsa kuti kusuta ndudu kumayambitsa khansa yam'mapapo, chifukwa imayambitsa kutupa, matenda ndikuchepetsa chitetezo chamthupi, zomwe zimabweretsa kusintha m'maselo am'mapapu. Komabe, mukasiya kusuta, kusintha kwama cell koopsa kumeneku kumayimitsidwa ndipo chiopsezo chokhala ndi khansa yamapapo chimachepa kwambiri.

Zotsatira zabwino za kusuta fodya zimawoneka pafupifupi nthawi yomweyo ndipo zikuwongolera bwino kwakanthawi komwe mudasiya kusuta, ngakhale kwa anthu azaka zapakati omwe amasuta kwazaka zambiri. Ndipo kafukufuku watsopanoyu adalimbikitsa izi, koma kubweretsa zotsatira zatsopano zolimbikitsa pakufunika kusiya kusuta, kuwonetsa mapapu kuthekanso kubwereranso ndikusiya fodya. Onani malangizo ena oti musiye kusuta.
