Munguva pfupi yapfuura, hofori mbiri dzefodya, PMI neBAT, dzakaburitsa mapepa ekutsvagisa mumagazini epamusoro ezvekurapa epasi rese.Mhedzisiro yetsvakiridzo inoratidza kuti zvigadzirwa zvitsva zvefodya senge e-fodya uye kupisa-kwete-kupisa hazvina kukuvadza uye zvine muchetura kupfuura fodya yechinyakare, uye inogona kuderedza zvakanyanya kukanganisa pakufema.kukuvadza.
Sezvo ruzivo rwevanhu pamusoro pengozi yekusvuta kunowedzera, e-cigarettes iri kuwedzera kuzivikanwa neveruzhinji sechinotsiva fodya.Nekudaro, iyo yenguva refu kukanganisa kwe flavoutede-fodyamusanganiswa wekunaka uye utsi hwefodya pane vanoputa zvinoramba zvichiongororwa.
Nguva pfupi yadarika, PMI Philip Morris International yakaburitsa gwaro rekutsvagisa "Kuongorora kwehupfu hwehutsi hwefodya uye aerosols kubva musanganiswa wekunhuhwirira: 5-vhiki yekudzidza muA/J mbeva" muBritish Journal yeToxicology "Journal yeApplied Toxicolog", ichitsanangura zvakadzama. yenyaya dzine hukama Matanho ekutsvagisa nemhedzisiro.
Mukuyedza, 87 mbeva dzechirume uye 174 nulliparous uye ane nhumbu mbeva dzechikadzi dzakapihwa zvisina tsarukano kumapoka ekuyedza 9, uye dzakaitwa mumhepo, utsi hwefodya, uye e-fodya aerosols ane matatu akasiyana eanonhuwirira, akakwirira, epakati, uye akaderera.Kuratidzwa kusvika kumaawa matanhatu pazuva, mazuva mashanu pasvondo, kwemavhiki mashanu kwakateverwa necropsy, uremu hwenhengo uye histopathological assessment.
Mufananidzo unoratidza data rekuongorora rekuzvimba kwegonzo remapapu.Zvinogona kuoneka kuti data rakakodzera rembeva dzakafumurwa utsi hwefodya ine mhinduro iri pachena (chikamu chitsvuku)
Mhedzisiro yekupedzisira yekuedza yakaratidza kuti apo mbeva dzakafumurwa kune e-fodya aerosols ine uye isina zvinonhuwirira, zvichienzaniswa neaya akafumurwa nehutsi hwefodya, pakanga pasina shanduko huru munhengo dzekufema, mhino, uye laryngeal epithelial tishu, izvo zvakaratidza kuti e-fodya. Iyo sol haina kutsamwisa kune inoenderana tishu uye nhengo.Migumisiro yekuedza inoratidza kuti, zvichienzaniswa nefodya yechinyakare,e-fodyainogona kuderedza zvakanyanya kuzvimba kwemapapu, pamwe nekukuvadzwa kwemhino, huro uye tracheal epithelium.
BAT British American Fodya yakaburitsa bepa rekutsvagisa rakanzi "An Experimental Analytical and In Vitro Approach to Bridge Between Different Heated Tobacco Product Variants" mu "Mipiro kuFodya & Nicotine Research" magazini yesainzi, uye yakaita tsvakiridzo paTHP (HNB zvigadzirwa) Toxicology. kuedza.
Mukuyedza, aerosols nehutsi hwefodya hwemhando shanu dzeTHP uye imwe yakakosha THP yakashandiswa senzvimbo yekuyedza, uye cytotoxicity yakaongororwa nekugona kwemasero emapapu epithelial emunhu.Mhedzisiro yacho yakaratidza kuti maitiro ese ecytotoxic muboka reTHP angangoita 95% akaderera pane ayo ari muboka refodya, uye pakanga pasina musiyano wakakura wehupfu pakati pemashanu akasiyana THPs uye THP yakakosha.
