Ucwaningo olusha oluvuna ugwayi we-elekthronikhi olwenziwe e-Pasteur Institute of Lille University Hospital lushicilelwe kule nyanga. Kuqokonyiswe uzakwethu ovela i-vapolitics, lo msebenzi ubonisa futhi “ ubuthi obuphansi be-vaping uma kuqhathaniswa nentuthu kagwayi".
I-VAPE ENGABUTHI BUNCANE KUNOSIGARETHI WE-BRONCHI
Ukuze sifinyelele kulesi siphetho, Sebastien Antherieu kanye nethimba lakhe labacwaningi badalula amangqamuzana entuthuni kagwayi kanye nomhwamuko we-e-cigarette ngokukhiqiza kabusha izimo ezingokoqobo zokusetshenziswa. Idokhumenti etholakala ku- iphephabhuku Toxicology in vitro chaza ukuthi"Nakuba intuthu kagwayi yehlise ngamandla ukusebenza kwamaseli ngemva kwemizuzu engama-48 yokuchayeka, ukufutha akubanga ne-cytotoxicity ngemva kwemizuzu engama-288 yokuchayeka.".
Ukwengeza, ithimba le Umthelela wamakhemikhali emvelo empilweni yabantu (IMPECS) futhi yenza ukuhlolwa kwemiphumela kuzakhi zofuzo. "Idatha ye-Transcriptomic evela kumaseli aveziwe ikhombisa inani elikhulu lezakhi zofuzo ezingalawuleki ngenxa yentuthu kagwayi (…) ngenkathi ukufutha kubangele ukuguquguquka okuncane kakhulu".
Isiphetho salolu cwaningo lwe-toxicological olwenziwa e-Pasteur Institute of Lille University Hospital ngamaseli e-bronchial epithelium yabantu sicacile: “Le miphumela iphakamisa ngokuqinile ubuthi obuphansi be-vaping uma kuqhathaniswa nentuthu kagwayi.".
IMIBANDELA YOKUSEBENZA KWEMISEBENZI
Inhloso yalolu cwaningo kwakuwukuhlola ukuhwamuka ngaphansi kwezimo ezingokoqobo ukuze kutholwe ukuthi ingabe kubangela ubuthi ngemva kokuchayeka okunamandla nokuphindaphindiwe, kanye nokuqhathanisa imiphumela yako naleyo yentuthu kagwayi.
Lolu cwaningo lwaqalwa ngoMashi 2014, lwasebenzisa ugwayi ojwayelekile wocwaningo (3R4F) kanye nemishini ene-cleaomizer nebhethri yohlobo lwe-ego engu-3,7 volts, enikelwe uhlobo lwe-Lille i-Nhoss, efakwe ama-resistors angu-2,8 Ohm. Uketshezi lwesiFulentshi lwezinhlobo ezintathu - ezingenalo iphunga, olunokunambitheka kukagwayi olu-blond kanye ne-chlorophyll mint ngakunye bekuyinguqulo engena-nicotine futhi ngesilinganiso esingu-16mg / ml. Ukuchayeka kwe-BEAS-2B stem cells kusitimu kwenziwe nge-air-liquid interface (ALI) ukuze kukhiqizwe kabusha izimo ezingokoqobo zokusebenza. "Lesi simiso siyakwazi ukufanisa izimo ezingokoqobo futhi silingise ngokweqiniso izimo zokuncibilika, ukugeleza, kanye nokuswakama kwe-vaping noma ukubhema," ucwaningo lubonisa, lusebenzisa izihloko ezikhonjweni ezikhuluma ngale ndaba.
«Uma ingekho iphrofayili ye-vaping esezingeni, ivolumu yokukhukhumala ephezulu kanye nemvamisa kukhethiwe. I-puff ichazwe ngevolumu engu-55 ml ngaphezu kwemizuzwana engu-3, ethathwe ngezikhathi zamasekhondi angu-30, kusetshenziswa iphrofayili ye-wave puff yesikwele.". Ngokuphambene, ukukhukhumala kukagwayi kumele ivolumu engu-35 ml ngamasekhondi angu-2, athathwe njalo ngamasekhondi angu-60, ngokuya ngezinga elidumile le-ISO emkhakheni (ISO 3308:2012). Iwebhusayithi " i-vapolitics "isho kanjalo" ukuthi sekukonke, ukufutheka kuye kwaba ngaphansi kohlobo lokudonsa okukhudlwana futhi okuphindwe kabili kunentuthu kagwayi. »
Ekugcineni, lolu cwaningo luphinde luveze iqiniso lokuthi ukusetshenziswa kukagwayi we-elekthronikhi kungabhekwa njengenye indlela yokubhema.
