Kev noj qab haus huv mus sij hawm ntev ntawm e-luam yeeb tseem tseem tsis tau paub ntau, tab sis cov no University of North Carolina toxicologists qhia tau hais tias lawv cov kev siv tsis yog qhov tseem ceeb rau cov noob uas koom nrog hauv kev tiv thaiv kev tiv thaiv kab mob ua pa sab saud. Thaum peb haus luam yeeb, ntau ntau cov noob uas koom nrog hauv kev tiv thaiv kab mob tau hloov pauv hauv cov hlwb epithelial uas kab hauv txoj hlab pa. Kev siv cov luam yeeb hluav taws xob yuav muaj kev cuam tshuam thoob ntiaj teb. Cov lus xaus yuav tsum luam tawm hauv American Journal of Physiology leej twg koom nrog cov kev hloov pauv ntawm epigenetic uas yuav muaj kev pheej hmoo ntawm kev kis kab mob thiab o.
Hauv tsab ntawv tshaj tawm los ntawm University, tus thawj coj sau ntawv, Dr. Ilona Jaspers, tus kws tshaj lij ntawm kev kho menyuam yaus thiab microbiology thiab immunology tau hais tias nws xav tsis thoob los ntawm cov txiaj ntsig no. Kev tshawb fawb tshwj xeeb qhia tau hais tias kev nqus cov kua vaporized ntawm e-luam yeeb tsis yog tsis muaj kev cuam tshuam rau qib ntawm cov noob qhia ntawm cov hlwb epithelial. Qhov kev nqus pa no yuav ua rau muaj kev hloov pauv ntawm epigenetic, uas yog hais txog cov noob caj noob ces thiab yog li hauv kev tsim cov protein tseem ceeb rau kev noj qab haus huv ntawm peb cov hlwb.
Pom tau thiab ua haujlwm zoo, cov txheej txheem epithelial ntawm peb qhov ntswg qhov ntswg zoo ib yam li cov txheej txheem epithelial ntawm peb lub ntsws. Tag nrho cov hlwb epithelial raws peb txoj hlab cua los ntawm peb lub qhov ntswg mus rau cov me me bronchioles hauv peb lub ntsws yuav tsum ua haujlwm kom zoo thiab tshem tawm cov kab mob thiab cov kab mob thiab yog li txo qhov kev pheej hmoo ntawm kev kis kab mob thiab o. Cov kab mob epithelial no yog qhov tseem ceeb rau kev tiv thaiv kab mob ib txwm muaj. Qee cov noob hauv cov hlwb no yuav tsum tau sau cov protein ntau txaus, uas ua rau lub cev tiv thaiv kab mob tag nrho. Nws tau paub ntev lawm tias kev haus luam yeeb hloov pauv qhov kev qhia ntawm cov noob no, uas yuav pab piav qhia tias yog vim li cas cov neeg haus luam yeeb muaj kev cuam tshuam rau cov kab mob ua pa sab sauv.
Hauv kev sim tshuaj xyuas qhov cuam tshuam ntawm e-luam yeeb ntawm cov noob uas cuam tshuam txog kev tiv thaiv peb txoj kev ua pa sab saud, pab pawg tau tshuaj xyuas cov ntshav thiab zis los ntawm 13 tus neeg tsis haus luam yeeb, 14 tus neeg haus luam yeeb thiab 12 tus neeg siv e-luam yeeb, txhawm rau txheeb xyuas cov qib nicotine. Txhua tus neeg tuaj koom kuj tau khaws daim ntawv teev npe teev lawv cov luam yeeb lossis siv e-luam yeeb. Tom qab 3 lub lis piam, cov kws tshawb fawb tau coj cov qauv los ntawm cov neeg koom nrog lub qhov ntswg los soj ntsuam cov kev qhia ntawm cov noob tseem ceeb rau kev tiv thaiv kab mob. Pab neeg pom tias,
- Cov luam yeeb txo cov kev qhia ntawm 53 cov noob tseem ceeb rau kev tiv thaiv kab mob ntawm cov hlwb epithelial,
- e-luam yeeb txo cov kev qhia ntawm 358 cov noob tseem ceeb rau kev tiv thaiv kab mob, suav nrog 53 cov noob koom nrog hauv pab pawg neeg haus luam yeeb.
Cov kws tshawb fawb sau tias lawv piv cov noob no ib qho los ntawm ib qho thiab pom tias txhua tus noob uas muaj rau ob pawg ntau dua " muffled dua nyob rau hauv e-luam yeeb pab pawg. Txawm li cas los xij, ntawm no lawv 
xaus rau qhov hnyav ntawm qhov tshwm sim ntawm ob qho kev coj ua.
Nyob rau theem no, cov no yog cov kev soj ntsuam molecular uas tseem tsis tau muaj feem cuam tshuam nrog kev noj qab haus huv mus sij hawm ntev los ntawm kev siv e-luam yeeb lossis nce kev pheej hmoo ntawm qee yam kab mob - raws li twb tau qhia txog kev haus luam yeeb (mob qog noj ntshav, emphysema, kab mob pulmonary mob ntev ...). Cov kws tshawb fawb lees paub tias lawv tseem tsis tau txheeb xyuas cov kev cuam tshuam ntev ntev no tab sis xav tias lawv yuav yog " txawv ntawm cov teebmeem ntawm cov luam yeeb ". Cov lus nug tseem nyob ntawm qhov cuam tshuam mus ntev, cov kab mob xws li COPD, mob qog noj ntshav lossis emphysema siv xyoo los tsim cov neeg haus luam yeeb. Kev tshawb fawb ntxiv yog npaj rau cov hlwb epithelial ntawm cov neeg siv e-luam yeeb…
