Tsis ntev los no, ob lub lag luam luam yeeb loj, PMI thiab BAT, feem ntau luam tawm cov ntaub ntawv tshawb fawb hauv cov ntawv xov xwm kho mob thoob ntiaj teb.Cov txiaj ntsig kev tshawb fawb pom tau tias cov khoom lag luam luam yeeb tshiab xws li e-luam yeeb thiab cov khoom siv hluav taws xob tsis kub hnyiab tsis muaj teeb meem 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 lees paub tias yog ib qho kev hloov luam yeeb, tab sis lub sij hawm ntev ntawm cov flavored e-luam yeeb tsw sib tov thiab 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 pa toxicity ntawm cov pa luam yeeb thiab aerosols los ntawm kev sib xyaw ua ke: 5-lub lim tiam 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 cov nas txiv neej thiab 174 cov nas uas cev xeeb tub thiab cev xeeb tub tau muab tso rau 9 pawg sim, thiab tau sim hauv 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.
Qhov kev ntsuam xyuas zaum kawg tau pom tias piv nrog cov pa luam yeeb, cov nas uas raug e-luam yeeb aerosols nrog thiab tsis muaj flavourants 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 hais tias e-luam yeeb lub sol tsis tshua muaj kev khaus. mus rau cov ntaub so ntswg thiab lub cev.Cov txiaj ntsig kev sim ntxiv tau ua pov thawj tias, piv nrog cov luam yeeb ib txwm, e-luam yeeb tuaj yeem txo qis kev mob ntsws, nrog rau kev puas tsuaj rau epithelium ntawm lub qhov ntswg, caj pas thiab trachea.
BAT British American Tobacco tau luam tawm cov ntawv tshawb fawb hu ua "Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Siv Hauv Vitro rau Choj Ntawm Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob sib txawv" hauv "Kev Pabcuam rau Kev Haus Luam Yeeb & Nicotine Research" phau ntawv tshawb fawb, thiab tau tshawb fawb txog THP (HNB cov khoom) Toxicology kuaj.Hauv kev sim, cov pa aerosol 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 tag nrho cov tshuaj tiv thaiv cytotoxic hauv THP pawg yog kwv yees li 95% qis dua li cov neeg hauv pawg neeg haus luam yeeb, thiab tsis muaj qhov sib txawv tseem ceeb ntawm toxicity ntawm tsib qhov sib txawv ntawm THPs thiab THP yooj yim.
Txoj kev tshawb no xaus lus tias kev txhim kho thiab muab cov khoom siv luam yeeb thiab nicotine lwm cov khoom lag luam 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 soj ntsuam toxicological yog tsim nyog ntawm 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.
