Ngenkathi amanye amadolobha e-United States ziyakwenqabela okwamanjet ama-e-liquids anongiwe, a isifundo esisha evela eBoston University School of Medicine imemezela ukuthi ithole ubuthi bephunga elimnandi emithanjeni yegazi.
I-E-CIGARETTE EYINGOZI YEMIKHUBA YEGAZI?
Ingabe ama-e-liquid anongiwe angabangela ukulimala komzimba? Lona umbuzo ithimba labacwaningi abavela eBoston University School of Medicine lazibuza wona.
Ikakhulukazi ngenxa yezithasiselo zokunambitheka ugwayi we-elekthronikhi uphumelele ukuzibonakalisa njengenye indlela yemikhiqizo kagwayi. Nakuba kuye kwenziwa ucwaningo oluningi ezingozini zikagwayi we-elekthronikhi wamaphaphu, zimbalwa kakhulu izifundo eziye zabheka imithambo yegazi nokuthi ama-flavour angawuthinta kanjani umzimba womuntu. Ngokukhethekile, azikho izifundo ezihlole ngokuqondile ubuthi bezithasiselo ezinongiwe emithanjeni yegazi.
Abacwaningi abavela ku-Faculty of Medicine I-Boston University (BUSM) ngakho-ke wafunda imiphumela yesikhashana yemikhiqizo 
amakhemikhali e-flavour asetshenziswa ku-e-cigarettes kuma-endothelial cells, amaseli ahlanganisa imithambo yegazi. Ngalolu cwaningo, abacwaningi baqaphela ukuthi lapho imithambo yegazi iboniswa izithasiselo zokunambitheka, amakhemikhali avame ukukhishwa ukuze akhuthaze ukugeleza kwegazi ehla futhi kwanda ukuvuvukala. Baphinde bathola ukuthi amangqamuzana e-endothelial avela kwababhemayo akhombisa ubuthi obufanayo nalawo aphathwa ngamakhemikhali anambitheka.
« Imiphumela yethu ibonisa ukuthi izithasiselo zokunambitheka zinobuthi emithanjeni yegazi futhi zinemiphumela emibi yesikhathi eside kubuthi benhliziyo nemithambo yegazi obufana nalokho okungabonwa ngokubhema ugwayi.", Chaza UJessica Fetterman, Ph.D., umsizi kaprofesa wezokwelapha e-BUSM.
Lokhu okutholakele kushicilelwe kumagazini i-Arteriosclerosis, Thrombosis, kanye ne-Vascular Biology. Ucwaningo luxhaswe yiNational Heart, Lung and Blood Institute (NHLBI), iCentre for Tobacco Products (CTP) ye-FDA.
