Kwiintsuku ezimbalwa ezidlulileyo, Hyun-Wook Lee, umphandi ovela kwiYunivesithi yaseNew York unayo ipapashe isifundo kwimpembelelo ye-aerosol yesigarethi ye-elektroniki kwiiseli zabantu kunye neempuku. Ngokwalolu cwaningo, i-e-cigarette ingaba yingozi kwiiparameters zentliziyo kunye neenqanawa, kwaye ngoko kubangele i-vasoconstriction, ukunyuka kwengcinezelo yegazi, izinga lentliziyo kunye nokuqina kwe-arterial. Nangona kunjalo, izazinzulu ezininzi zomphunga zakhawuleza zayigxeka iprotocol yolu phononongo, ephinda ibonakala ngathi ityhola isixhobo esidumileyo.
UMHLAZA, ISIFO SENTLIZIYO... XA OOONOndaba BESIGQIBELA I-E-CIGARETT NGAPHANDLE KOBUGQINA!
Kwanele ukuthetha ukuba ngethuba elinjalo le-buzz, i-AFP (i-Agence France Presse) kunye nenxalenye enhle yeendaba zaziphosela kwifayile njengabantu abalambileyo ngaphandle kokuthatha ixesha lokuqhagamshelana nososayensi abambalwa eYurophu. Ukusukela izolo ngokuhlwa, sifumana kuyo yonke indawo isihloko esifanayo " Imidiza ye-elektroniki yonyusa umngcipheko wee-cancer ezithile ukongezelela kwisifo sentliziyo ngomxholo othengiswe kwangaphambili yi-AFP.
"Ngokutsho kweempapasho ezithile zesayensi, i-e-cigarette ingaba yingozi kwiiparamitha zentliziyo kunye neenqanawa, kwaye ngoko kubangele i-vasoconstriction, ukunyuka kwengcinezelo yegazi, ukubetha kwentliziyo kunye nokuqina kwe-arterial. Kule meko, zonke iiparameters ezaziwayo ukuba zihambelana nempilo ye-cardiovascular.
Yiba nokuba kunjalo, ngokomsebenzi wamva nje wabaphandi kwiSikolo seYunivesithi yaseNew York, epapashwe ngoMvulo kwiiProceedings of I-American Academy of Sciences (PNAS), ukutshaya i-e-cigarettes kunokwandisa ingozi yomhlaza othile kunye nesifo senhliziyo. Ngokwenene, ngokweziphumo zokuqala zophononongo olwenziwa kwiimpuku kunye neeseli zabantu elabhoratri, umphunga wenikotini unokuba yingozi ngakumbi kunokuba bekucingelwa ngaphambili.
Ukusuka kulo msebenzi, kubonakala ngathi, xa zisesichengeni sokuphefumla kangangeeveki ezilishumi elinambini, iintonga zaphefumla umphunga wenikotini olingana nethamo kunye nobude beminyaka elishumi yokufunxa ebantwini! Ekupheleni kolu vavanyo, izazinzulu zaqaphela: Umonakalo we-DNA kwiiseli zemiphunga, isinyi kunye nentliziyo yezi zilwanyana kunye nokuncipha kwinqanaba leeprotheyini zokulungisa iiseli kula malungu xa kuthelekiswa neempuku eziphefumle umoya ohluziweyo ngexesha elinye.".
Kwaye akuphelelanga apho: iziphumo ezibi ezifanayo ziye zabonwa kwimiphunga yomntu kunye neeseli zesinyi ezivezwe elabhoratri kwinikotini kunye ne-carcinogenic derivative yale nto (nitrosamine). Ezi seli ziye zafumana amazinga aphezulu otshintsho lwethumba.
« Nangona i-e-cigarettes iqulethe i-carcinogens embalwa kune-cigarettes eqhelekileyo, i-vaping inokubeka umngcipheko omkhulu wokuba nomhlaza wemiphunga okanye wesinye kunye nesifo senhliziyo.", bhala abaphandi aba UNjingalwazi Moon-Shong Tang, unjingalwazi weyeza lokusingqongileyo kunye ne-pathology kwiYunivesithi yaseNew York School of Medicine, umbhali okhokelayo. »
Ke ngaba kufuneka sibe nexhala malunga nesi sifundo sijikeleza kumajelo eendaba nakushicilelo nakumajelo eendaba akwi-intanethi? Andiqinisekanga kangako...
“INDLELA ENGAYIXELISI IMIQATHA EQHELEKILEYO YOKUSETYENZISWA KWAKHONA”
Kungenxa yokuba imidiya eqhelekileyo ayithethi ngayo ayithethi ukuba izazinzulu ezizingcaphephe kulo msebenzi azinalizwi lazo! Yaye ngokufuthi emva kokupapashwa kwesifundo, kuviwa amazwi athile!
Kwaye kuninzi ukucacisa kwangoko ukuba umntu unokuthetha ngokulula into ayifunayo kwisifundo " indlela ayifani kwaphela iimeko eziqhelekileyo zokusetyenziswa".
Kwinqaku kwisiza News US, INyanga iShong Tang, umbhali-mbhali wesifundo esidumileyo uthe « Sifumene ukuba i-e-cigarette aerosol engenanikotine ayibangeli monakalo weDNA« echaza ukuba " LI-e-liquid enenikotini yenza umonakalo ofanayo kwinikotini iyodwa". Ngokucacileyo, iya kuba yingxaki yenikotini hayi i-e-liquid? Iyamangalisa akunjalo? Ude athi umonakalo obonwe ngala mayeza enikotini kwimpuku ungalingana nalowo ubonwa ebantwini xa betshaya. Uchaza kwiiNdaba zase-US ukuba ngedatha ekubo akunakwenzeka ukuba kuqinisekiswe iziphumo ezinomhlaza.
Ezinye izazinzulu ezininzi ziye zawuthatha lo mbandela, njenge UProf. Peter Hajek, uMlawuli weYunithi yoPhando ngokuxhomekeka kwiCuba kwiYunivesithi yaseQueen Mary yaseLondon othi:
« Iiseli zabantu zazintywiliselwe kwinikotini kunye ne-carcinogenic nitrosamines ezithengwe kwimarike. Ayimangalisi into yokuba yonakalisa iiseli, kodwa loo nto ayinanto yakwenza neziphumo zevaping ebantwini abayisebenzisayo. »
Ku UNjingalwazi uRicardo Polosa ukusuka kwiYunivesithi yaseCatania, kukho ingxaki ngokucacileyo kwindlela esetyenziswayo :
« Indlela echazwe ngababhali ayilingisi iimeko eziqhelekileyo zokusetyenziswa kweemveliso zomphunga. Iimeko eziveliswe kwakhona kolu vavanyo zibaxiwe kwaye zikhetha ukuveliswa kwezinto eziyityhefu. Izifundo zethu zezigulane ezinesifo semiphunga azibonisi nje ukungabikho komonakalo kodwa zigxininisa ukuphuculwa okufanayo okunokuthi kuphunyezwe ngokuyeka ukutshaya. ".
Okokugqibela, kubonakala ukuba ngexesha lovavanyo, impuku nganye yaphefumlela kude I-20 ye-puffs ngosuku kanti kwimeko yesiqhelo umntu uphakathi 200 kunye 300 ukufunxa. Le datha iyodwa iya kwanela ukwenza kucace ukuba uphononongo olunikezelwe ngu Hyun-Wook Lee ayikho serious kakhulu.
