Ngoxa ezinye izixeko eUnited States akuvumelekanga ngokut ii-e-liquids ezinencasa, a isifundo esitsha evela kwiYunivesithi yaseBoston yeSikolo sezoNyango ibhengeza ukuba ibone ubutyhefu bamavumba emithanjeni yegazi.
I-E-CIGARETTE EYINGOZI YEMISHIYA YEGAZI?
Ngaba ii-e-liquids ezinencasa zinokubangela ukwenzakala emzimbeni? Lo ngumbuzo elazibuza wona iqela labaphandi abavela kwiYunivesithi yaseBoston yeSikolo sezoNyango.
Ubukhulu becala ngumbulelo kwizongezo zencasa yokuba i-e-cigarette iphumelele ekuzimiseni njengenye yeemveliso zecuba. Nangona uphando oluninzi luqhutywe kwiingozi ze-e-cigarettes kwimiphunga, zimbalwa kakhulu izifundo eziye zajonga imithwalo yegazi kunye nendlela i-flavouring inokuchaphazela ngayo umzimba womntu. Ngokukodwa, akukho zifundo ziye zavavanya ngokuthe ngqo ubutyhefu bezongezo ezinencasa kwimithambo yegazi.
Abaphandi abavela kwiFaculty of Medicine IYunivesithi yaseBoston (BUSM) ngoko wafunda iziphumo zexesha elifutshane zeemveliso 
iikhemikhali zokunambitha ezisetyenziswa kwi-e-cigarettes kwiiseli ze-endothelial, iiseli ezihamba kwimithambo yegazi. Ngolu pho nonongo, abaphandi baqaphela ukuba xa imithambo yegazi ibonakaliswe kwizongezo ze-flavoring, iikhemikhali zivame ukukhutshwa ukukhuthaza ukuhamba kwegazi kwehle kwaye kwanda ukuvuvukala. Baye bafumanisa ukuba iiseli ze-endothelial ezivela kwabatshayayo zibonise ubuthi obufana nobo baphathwa ngeekhemikhali zokuvumba.
« Iziphumo zethu zibonisa ukuba izongezo ze-flavoring ziyityhefu kwimithambo yegazi kwaye zineziphumo ezibi zexesha elide kwi-cardiovascular toxicity efana noko kunokubonwa ngokutshaya icuba.Chaza UJessica Fetterman, Ph.D., unjingalwazi oncedisayo wamayeza e-BUSM.
Ezi ziphumo zipapashwe kwiphephancwadi Arteriosclerosis, Thrombosis, kunye ne-Vascular Biology. Uphononongo luxhaswe ngemali yiNational Heart, Lung and Blood Institute (NHLBI), iZiko leMveliso yeCuba (CTP) ye-FDA.
