Tsis ntev los no, ob lub lag luam luam yeeb loj, PMI thiab BAT, luam tawm cov ntaub ntawv tshawb fawb hauv cov ntawv xov xwm kho mob thoob ntiaj teb.Cov txiaj ntsig ntawm kev tshawb fawb pom tau tias cov khoom luam yeeb tshiab xws li e-luam yeeb thiab kub tsis kub tsis tshua muaj kev phom sij thiab tshuaj lom ntau dua li cov luam yeeb ib txwm muaj, thiab tuaj yeem txo qhov cuam tshuam rau kev ua pa.ua mob.
Raws li tib neeg txoj kev paub txog kev phom sij ntawm kev haus luam yeeb tob zuj zus, e-luam yeeb tau pom zoo los ntawm pej xeem ua ib qho kev hloov luam yeeb.Txawm li cas los xij, lub sij hawm ntev cuam tshuam ntawm flavorede-luam yeebKev sib xyaw tsw thiab cov pa luam yeeb ntawm cov neeg haus luam yeeb tseem yuav tau tshawb nrhiav ntxiv.
Tsis ntev los no, PMI Philip Morris International tau tshaj tawm tsab ntawv tshawb fawb "Kev soj ntsuam ntawm kev nqus tshuaj lom ntawm cov pa luam yeeb thiab aerosols los ntawm kev sib xyaw ua ke: 5-lub lim tiam kev kawm hauv A / J nas" hauv British Journal of Toxicology "Journal of Applied Toxicolog", piav qhia cov ntsiab lus ntawm cov ncauj lus ntsig txog Kev Tshawb Fawb cov kauj ruam thiab cov txiaj ntsig.
Hauv kev sim, 87 txiv neej nas thiab 174 nulliparous thiab poj niam cev xeeb tub nas tau muab tso rau 9 pawg sim, thiab ua rau huab cua, luam yeeb, thiab e-luam yeeb aerosols nrog peb qhov sib txawv ntawm flavorants, siab, nruab nrab, thiab qis.Kev tawm mus txog 6 teev hauv ib hnub, 5 hnub hauv ib lub lis piam, rau 5 lub lis piam tau ua raws li necropsy, qhov hnyav ntawm lub cev thiab kev ntsuas histopathological.
Daim duab qhia cov ntaub ntawv ntsuam xyuas ntawm nas mob ntsws.Nws tuaj yeem pom tau tias cov ntaub ntawv cuam tshuam ntawm cov nas kis tau cov pa luam yeeb muaj cov lus teb pom tseeb tshaj plaws (liab feem)
Qhov kev sim zaum kawg tau pom tias thaum cov nas tau raug e-luam yeeb aerosols nrog thiab tsis muaj flavorants, piv nrog rau cov pa luam yeeb, tsis muaj kev hloov pauv tseem ceeb hauv cov kab mob ua pa, qhov ntswg, thiab cov ntaub so ntswg laryngeal epithelial, uas qhia tau tias e-luam yeeb. Lub sol tsis tshua khaus rau cov ntaub so ntswg thiab lub cev.Cov txiaj ntsig kev sim ntxiv ua pov thawj tias, piv nrog cov luam yeeb,e-luam yeebtuaj yeem txo qhov mob ntsws, nrog rau kev puas tsuaj rau lub qhov ntswg, caj pas thiab tracheal epithelium.
BAT British American Tobacco tau luam tawm cov ntawv tshawb fawb hu ua "Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Siv Hauv Vitro rau Choj Ntawm Cov Khoom Siv Hluav Taws Xob Ntau Yam" nyob rau hauv "Kev Pabcuam rau Kev Haus Luam Yeeb & Nicotine Research" phau ntawv tshawb fawb tshawb fawb, thiab tau tshawb fawb txog THP (HNB cov khoom) Toxicology kuaj.
Hauv kev sim, aerosols thiab luam yeeb ntawm tsib qhov txawv ntawm THP thiab ib qho THP yooj yim tau siv los ua qhov chaw sim, thiab cytotoxicity tau soj ntsuam los ntawm kev muaj peev xwm ntawm tib neeg lub ntsws epithelial hlwb.Cov txiaj ntsig tau pom tias txhua qhov kev cuam tshuam cytotoxic hauv pawg THP yog kwv yees li 95% qis dua li cov neeg nyob hauv pawg neeg haus luam yeeb, thiab tsis muaj qhov sib txawv tseem ceeb ntawm cov tshuaj lom ntawm tsib qhov sib txawv ntawm THPs thiab THP yooj yim.
Raws li txoj kev tshawb fawb, kev txhim kho thiab muab cov khoom siv luam yeeb thiab cov khoom siv nicotine tau loj hlob sai, cov neeg siv khoom tau txais cov khoom tshiab xws li THP, thiab nws txoj kev nyab xeeb thiab kev pheej hmoo ua ib feem ntawm kev ntsuas tshuaj lom neeg yog tsim nyog rau kev lag luam.Tsuas yog thaum cov khoom ua tau raws li cov qauv (xws li roj teeb kev ua tau zoo) nws tuaj yeem ua tau zoo dua nws lub luag haujlwm zoo raws li lub tswv yim kev noj qab haus huv rau pej xeem.
