Nicotine vapor inobva kumidzanga yemagetsi haina muchetura kumasero emapapu pasi pemamiriro echokwadi ekushandiswa, inopedzisa ongororo yakaitwa nevatsvagiri vefodya vanomwe veBritish American, vachitungamirwa naDavid Azzopardi, chiremba wemicrobiologist uye nyanzvi mukuongorora njodzi yezvigadzirwa zvefodya.
Uye kunyangwe kana mhute iyi yakayedzwa mune yakanyanya kuwanda, iyo cytotoxicity yefodya yemagetsi yakaderera zvakanyanya pane iyo yefodya yakajairika.
Kuyera in vitro kukuvadza kunobvira kwekuputira pamasero emapapu emunhu, nekuienzanisa nehupfu (hwaimbozivikanwa) hwehutsi hwefodya, masayendisiti akashandisa "kusvuta muchinakutevedzera manwiro chaiwo kunze kwekunge mhute yese kana chiutsi chakasvika munyama yemapapu, izvo zvisiri izvo muhupenyu chaihwo.
Mumasero aifanira kucherechedzwa, vatsvakurudzi vakanga vambobaya mucherechedzo wemavara: apo masero akanga ane utano, vakaramba vakatsvuka, uye pavakatanga kufa, vakashandura pink. Sei? Nokuti ivo vapenyu, masero anokwanisa "kugaya" mucherechedzo mu lysosomes yavo, "cellular trash can" apo tsvina isingakoshi kuhupenyu hwesero inoiswa. Ukuwo, kana masero angofa kana kufa, dhayi haichaendi kupi zvako uye masero anobva achinja ruvara.
Mumamiriro ezvinhu epamhepo echokwadi, maseru akaramba ari matsvuku - uye nekukasira kushanduka kuva pink paakapinzwa nehutsi hwefodya. Kana zviri zvekutanga zviratidzo zve cytotoxicity kubva kumidzanga yemagetsi, zvinoonekwa pamadosi zvekuti hapana chero munhu, chero kwese kwese, anokwanisa kusveta - zvakaenzana nezuva rekupfuta rakadzvanywa kuita awa rimwechete. Asi, kunyangwe pasi pemamiriro ezvinhu akanyanya aya, fodya yemagetsi inoramba iine chepfu kumasero emapapu pane yakajairika mudzanga.
Chidzidzo chinosimbisa vamwe vanocherekedza huturu hwakaderera hwefodya yemagetsi zvichienzaniswa nefodya yakajairika.
