Dhawaan, laba kooxood oo waaweyn oo tubaakada, PMI iyo BAT, ayaa siday u kala horreeyaan u daabaceen waraaqo cilmi baaris ah joornaalada caafimaadka ee caalamiga ah.Natiijooyinka cilmi-baarista ayaa muujinaya in waxyaabaha cusub ee tubaakada sida sigaarka elektaroonigga ah iyo kuwa kulaylka aan guban ay ka dhib yar yihiin kana sun yihiin sigaarka dhaqameed, waxayna si weyn u yareyn karaan saameynta habka neefsashada.dhib.
Marka wacyiga dadka ee khatarta sigaarku sii korodho, sigaarka elektaroonigga ah ayaa si isa soo taraysa loo aqoonsanayaa inuu yahay beddelka sigaarka, laakiin saamaynta muddada-dheer ee isku-dhafka dhadhanka sigaarka elektaroonigga ah iyo qiiqa sigaarka ee sigaarka cabba ayaa weli ah in la sii baadho.Dhawaan, PMI Philip Morris International ayaa daabacday warbixin cilmi baaris ah "Qiimaynta sunta neefsashada ee qiiqa sigaarka iyo aerosols ee isku dhafka dhadhanka: daraasad 5-usbuuc ah oo ku jirta jiirarka A/J" ee Joornaalka Toxicology ee Ingiriiska "Journal of Applied Toxicolog", oo sharraxaya faahfaahinta Mawduucyada la xidhiidha Tillaabooyinka cilmi-baarista iyo natiijooyinka.
Tijaabada, 87 jiirar lab ah iyo 174 jiirar nulliparous iyo dheddig oo uur leh ayaa si aan kala sooc lahayn loogu qoondeeyay 9 kooxood oo tijaabo ah, waxaana lagu tijaabiyay hawada, qiiqa sigaarka, iyo aerosols sigaarka elektaroonigga ah oo leh saddex qaybood oo kala duwan oo dhadhan ah, sare, dhexdhexaad ah, iyo hoose. .Soo-gaadhista ilaa 6 saacadood maalintii, 5 maalmood usbuucii, 5 toddobaad ayaa la raacay necropsy, miisaanka xubnaha iyo qiimaynta histopathological.
Natiijooyinka baaritaanka ugu dambeeya waxay muujiyeen in marka la barbardhigo soo-gaadhista qiiqa sigaarka, jiirarka soo gaadhay hawada sigaarka e-sigaarka leh iyo kuwa aan dhadhan lahayn wax isbeddel ah oo la taaban karo ku yeelan xubnaha neefsashada, sanka, iyo unugyada epithelial laryngeal, taas oo muujisay in sigaarka elektaroonigga ah solku uu ka yar yahay xanaaqa. unugyada iyo xubnaha u dhigma.Natiijooyinka tijaabada ah waxay sii caddeeyeen in, marka la barbardhigo sigaarka dhaqameed, sigaarka elektaroonigga ah uu si weyn u dhimi karo caabuqa sambabada, iyo sidoo kale dhaawaca epithelium ee sanka, dhuunta iyo hawo-mareenka.
BAT British American Tubaakada ayaa daabacday warqad cilmi baaris ah oo ciwaankeedu yahay "An Tijaabo Analytical iyo In Vitro Approach to Bridge u dhexeeya Kala duwanaanshaha Alaabta Tubaakada kulul ee Kulul" ee "wax ku biirinta Tubaakada & Cilmi-baarista Nikotiinka" joornaalka sayniska, waxayna samaysay cilmi-baaris ku saabsan THP ( alaabta HNB) Toxicology tijaabinaya.Tijaabada, aerosol-ka iyo qiiqa sigaarka ee shan nooc oo THP ah iyo hal THP aasaasiga ah ayaa loo isticmaalay jawi tijaabo ah, iyo cytotoxicity waxaa lagu qiimeeyay suurtagalnimada unugyada epithelial sambabada bini'aadamka.Natiijooyinku waxay muujiyeen in dhammaan falcelinta cytotoxic-ka ee kooxda THP ay 95% ka hooseeyaan kuwa ku jira kooxda qiiqa sigaarka, mana jirin farqi weyn oo u dhexeeya sunta u dhaxaysa shanta nooc ee THPs iyo THP aasaasiga ah.
Daraasadu waxay soo gabagabaysay in horumarinta iyo sahayda tubaakada iyo nicotine-ka kale ay si xawli ah u korayaan, macaamiishu waxay si sii kordheysa u aqbalayaan alaabada cusub sida THP, iyo badbaadada iyo khatarta iyada oo qayb ka ah qiimeynta sunta sunta ah ay mudan yihiin dareenka warshadaha.Kaliya marka alaabtu ay buuxiso heerarka (oo ay ku jiraan waxqabadka batteriga) ayaa si fiican u ciyaari kara doorkeeda togan ee istiraatijiyadda caafimaadka dadweynaha.
