Ngokophononongo olutsha lobunjineli oluvela kwiYunivesithi yaseOhio, imidiza ye-elektroniki iya kuba yingozi kakhulu kunemidiza eqhelekileyo emiphungeni.
NGOKUFANELEKILEYO NOMSI, UMphunga AWUCHAPHAZEKI UMNTU WEMIPHUMELA!
U-Amir Farnoud, unjingalwazi oncedisayo kubunjineli beekhemikhali kunye ne-biomolecular kwiKholeji yaseRuss yobuNjineli neTekhnoloji, kunye neqela lakhe liphande ukuba i-e-cigarettes kunye ne-vaping e-liquid inokuchaphazela njani i-lung surfactant.
I-Lung surfactant ngumxube we-lipids kunye neeproteni ezijikeleza ummandla we-alveolar wemiphunga, ukunciphisa ukuxinezeleka komphezulu we-alveolar fluid, ukuthintela ukuwa kwemiphunga kwaye ngaloo ndlela kunciphisa umsebenzi wokuphefumla. Nangona uphando oluninzi luye lwajonga indlela i-e-cigarettes inokuchaphazela ngayo iiseli kwi-airways, iqela leYunivesithi yase-Ohio lalifuna ukubona ukuba umphunga oveliswa yi-e-cigarette uthintele amandla omntu osebenzisa i-surfactant ekunciphiseni ukuxinana komhlaba.
Kuye kwafunyaniswa ukuba ukutshiswa kwetar ekhoyo kwi-cigarette ye-classic kunokuba yingozi kwi-pulmonary surfactant kodwa. ukuba amasuntswana akwi-aerosol engumphunga akachaphazelanga ukusebenza okuqhelekileyo kwe-surfactant. Kunokubakho izizathu ezininzi zoku: Okokuqala ukusetyenziswa kwe-e-cigarette kubandakanya ukuphunga kunye nokungatsha kwaye okwesibini, imidiza yesiqhelo ithintela ngokubonakalayo ukukwazi kwe-surfactant ukunciphisa ukuxinezeleka komhlaba.
« Ubuncinci siyazi ukuba umaleko wokuqala okhuselayo awuzukuchaphazeleka."Utshilo uFarnoud, esongeza ukuba iziphumo aziyikhuphi ngokupheleleyo
enokubakho "ityhefu" isiphumo imidiza electronic.
Abaphandi babhentsise zombini umsi wecuba kunye nomphunga we-e-cigarette kwisicatshulwa se-calf lung surfactant (Infasurf, ONY Inc.), esetyenziselwa ukunyanga iintsana ezizelwe phambi kwexesha ezingekaveli i-surfactant. Uphononongo, iintlobo ezintathu ezahlukeneyo ze-e-liquid (icuba, iziqhamo kunye ne-mint) zisetyenzisiwe.
« Kukho umdla omkhulu ekuqondeni iziphumo zomphunga kwimpilo yemiphunga", utshilo uFarnoud, eqaphela ukuba umphunga kufuneka uqale udlule kwi-surfactant ngaphambi kokuba ufikelele kwiiseli ezinzulu zemiphunga.
