Masiku angapo apitawo, Hyun-Wook Lee, wofufuza wochokera ku yunivesite ya New York watero adafalitsa kafukufuku pa mphamvu ya aerosol ya ndudu yamagetsi pama cell a anthu ndi mbewa. Malinga ndi kafukufukuyu, ndudu ya e-fodya ikhoza kukhala yovulaza kwa magawo a mtima ndi ziwiya, motero imayambitsa vasoconstriction, kuwonjezeka kwa kuthamanga kwa magazi, kugunda kwa mtima ndi kuuma kwa mitsempha. Komabe, asayansi angapo opumira sanachedwe kudzudzula ndondomeko ya phunziroli, yomwe ikuwoneka kuti ikutsutsa molakwika chipangizo chodziwika bwino.
KANSA, MATENDA WA MTIMA… PAMENE AKATSANI AMATSUTSA Ndudu wa E-PI POPANDA UMBONI!
Zokwanira kunena kuti ndi mwayi wotero wa buzz, AFP (Agence France Presse) ndi gawo labwino lazofalitsa adadziponyera mu fayilo ngati anthu omwe ali ndi njala popanda ngakhale kutenga nthawi kuti alankhule ndi asayansi ochepa ku Ulaya. Kuyambira dzulo madzulo, tikupeza kulikonse mutu womwewo “ Ndudu zamagetsi zimawonjezera chiopsezo cha khansa zina kuwonjezera pa matenda a mtima ndi zomwe zidagulitsidwa kale ndi AFP.
"Malinga ndi zofalitsa zina za sayansi, ndudu ya e-fodya ikhoza kukhala yovulaza kwa magawo a mtima ndi mitsempha, motero imayambitsa vasoconstriction, kuwonjezeka kwa kuthamanga kwa magazi, kugunda kwa mtima ndi kuuma kwa mitsempha. Pankhaniyi, magawo onse omwe amadziwika kuti amagwirizana ndi thanzi la mtima.
Zikhale momwe zingakhalire, malinga ndi ntchito yaposachedwa ndi ofufuza a New York University School of Medicine, lofalitsidwa Lolemba mu Proceedings of American Academy of Sciences (PNAS), kusuta fodya wa e-fodya kungayambitse matenda a khansa komanso matenda a mtima. Zowonadi, molingana ndi zotsatira zoyambirira za kafukufuku yemwe adachitika pa mbewa ndi maselo amunthu mu labotale, nthunzi ya chikonga ikhoza kukhala yovulaza kuposa momwe amaganizira kale.
Kuchokera pa ntchitoyi, zikuwoneka kuti, atakumana ndi mpweya kwa milungu khumi ndi iwiri, makoswe adakoka nthunzi wa chikonga wofanana ndi mlingo ndi nthawi yake mpaka zaka khumi zakupuma kwa anthu! Pamapeto pa kuyesaku, asayansi adawona: Kuwonongeka kwa DNA m'maselo a m'mapapo, chikhodzodzo ndi mtima wa nyamazi komanso kuchepetsa kuchuluka kwa mapuloteni okonzanso maselo m'zigawozi poyerekeza ndi mbewa zomwe zinapuma mpweya wosefedwa panthawi yomweyi.".
Ndipo si zokhazo: zotsatira zoyipa zofananira zawonedwa m'maselo a m'mapapo ndi chikhodzodzo chamunthu omwe amawululidwa mu labotale ku chikonga ndi chochokera ku carcinogenic cha mankhwalawa (nitrosamine). Ma cellwa adakhalapo ndi kusintha kwakukulu kwa chotupa.
« Ngakhale ndudu za e-fodya zili ndi ma carcinogens ochepa kuposa ndudu wamba, kutulutsa mpweya kumatha kukhala ndi chiopsezo chachikulu chokhala ndi khansa ya m'mapapo kapena chikhodzodzo komanso kudwala matenda amtima.", lembani ofufuza omwe Pulofesa Moon-Shong Tang, pulofesa wa zamankhwala zachilengedwe ndi matenda ku New York University School of Medicine, wolemba wamkulu. »
Ndiye kodi tiyenera kuda nkhawa ndi kafukufukuyu yemwe akupezeka m'matchanelo a nkhani komanso m'manyuzipepala komanso pawailesi yakanema? Osatsimikiza…
“NJIRA YOMWE SIIMATSANZIRA MABWINO WOGWIRITSA NTCHITO KANTHU”
Chifukwa chakuti atolankhani ambiri salankhula za izi sizitanthauza kuti asayansi odziwa bwino ntchitoyi alibe zonena zawo! Ndipo kaŵirikaŵiri pambuyo pa kufalitsidwa kwa phunziro, mawu ena amamveka!
Ndipo zambiri kufotokoza nthawi yomweyo kuti munthu akhoza kunena mosavuta zomwe akufuna ku phunziro lomwe " njira sizimatsanzira zonse zomwe zimagwiritsidwa ntchito".
Pankhani patsamba US News, Moon Shong Tang, wolemba nawo wa kafukufuku wotchuka anati « Tidapeza kuti e-fodya ya e-fodya yopanda chikonga sichiwononga DNA« kunenanso kuti " Le-madzi okhala ndi chikonga anawononga mofanana chikonga yekha". Mwachiwonekere, lingakhale vuto la chikonga osati e-madzi? Zodabwitsa sichoncho? Amanenanso kuti chikonga chomwe chimawonongeka ndi mbewa ngati chiwopsezochi chingakhale chofanana ndi chomwe chimawonedwa mwa anthu omwe amangosuta basi. Ananenanso mu US News kuti ndi zomwe ali nazo sizingatheke kutsimikizira zotsatira za khansa.
Asayansi ena ambiri atenganso nkhaniyi, monga Prof. Peter Hajek, Mtsogoleri wa Tobacco Dependence Research Unit ku Queen Mary University of London yemwe anati:
« Maselo a anthu adamizidwa mu chikonga ndi ma nitrosamines a carcinogenic omwe adagulidwa pamsika. N'zosadabwitsa kuti amawononga maselo, koma izo ziribe kanthu kochita ndi zotsatira vaping ali pa anthu amene ntchito. »
Kwa Prof Ricardo Polosa kuchokera ku yunivesite ya Catania, pali vuto mu njira yomwe imagwiritsidwa ntchito :
« Njira yofotokozedwa ndi olembayo satengera momwe zinthu ziliri pakugwiritsa ntchito vaping mankhwala. Mikhalidwe yopangidwanso m'zoyeserazi ndiyokokomeza ndipo imakonda kupanga zinthu zapoizoni. Maphunziro athu a odwala omwe ali ndi matenda a m'mapapo samangosonyeza kusakhalapo kwa zowonongeka koma amatsindikanso zomwezo zomwe zingatheke posiya kusuta. ".
Pomaliza, zikuwoneka kuti pakuyesa, mbewa iliyonse idakoka mpweya mpaka 20 zopumira patsiku pamene mu chikhalidwe chachibadwa munthu ali pakati 200 ndi 300 zopumira. Deta yokhayo ingakhale yokwanira kuti iwonetsetse kuti phunzirolo linaperekedwa ndi Hyun-Wook Lee si serious kwambiri.
