Malinga ndi kafukufuku wofalitsidwa mu nyuzipepala ya Clinical and Translational Allergy, magawo onyamulira mpweya omwe ali ndi mpweya wokwanira woperekera mpweya amatha kuchotsa nthata, amphaka ndi agalu, ndikutulutsa zinthu kuchokera mumlengalenga wamkati.
Ofufuzawo amachitcha kuti kafukufuku wozama kwambiri, woyang'ana kwambiri kusefera kwa mpweya kwa zinthu zingapo zoyendetsedwa ndi mpweya m'zipinda zogona.
"Zaka ziwiri phunziroli lisanachitike, ofufuza angapo ku Europe ndi ine tinali ndi msonkhano wasayansi wokhudzana ndi mpweya wabwino komanso ziwengo," adatero Jeroen Buters, PharmD, toxicologist, wachiwiri kwa director wa Center for Allergy and Environment, komanso membala wa Germany Center Munich. Makampani The Lung Research Center ku Yunivesite ndi Helmholtz Center adauza Healio.
Ofufuzawo adafufuza Dermatophagoides pteronyssinus Der p 1 ndi Dermatophagoides farinae.Der f 1 nyumba fumbi mite allergen, Fel d 1 cat allergen ndi Can f 1 galu allergen, zonsezi zimatha kuzindikirika muzinthu zowuluka ndi mpweya (PM).
"Aliyense amaganiza kuti Dermatophagoides pteronyssinus ndiye nthata zazikulu zomwe zimatulutsa allergen m'banja.Osati - osachepera osati ku Munich, ndipo mwina osati kwina.Kumeneko ndi Dermatophagoides farinae, nthata ina yogwirizana kwambiri.Pafupifupi odwala onse adathandizidwa ndi D pteronyssinus.Chifukwa cha kufanana kwakukulu pakati pawo, izi zinali bwino, "adatero Butters.
“Komanso, nthata iliyonse imakhala ndi moyo mosiyana, kotero kuti udziwe bwino yomwe ukunena.Ndipotu, pali anthu ambiri ku Munich omwe amakhudzidwa ndi D. farina kuposa D. pteronyssinus, "adapitiriza..
Ofufuza adayendetsa maulendo oyendetsa ndi kulowererapo m'nyumba iliyonse pazigawo za masabata a 4. Pa nthawi yoyendera, iwo ankaimira zochitika zosokoneza fumbi mwa kugwedeza pilo kwa masekondi a 30, chophimba cha bedi kwa masekondi 30, ndi bedi kwa masekondi 60.
Kuphatikiza apo, ofufuzawo anayeza kuchuluka kwa Der f 1 m'zipinda zogona za nyumba zinayi ndipo adapeza kuti kuchuluka kwapakatikati kunali 63.2% kutsika kuposa zomwe zili m'zipinda zogona.
"Kafukufuku waku Australia adapeza zosokoneza zambiri pabalaza la sofa.Sitinatero.Tinazipeza pakama.Mwina ndi gradient yaku Australia-European, "adatero Butters.
Pamapeto pa chochitika chilichonse, ofufuzawo adatsegula choyeretsacho ndikuchiyendetsa kwa ola la 1. Njirayi inabwerezedwa kanayi paulendo uliwonse, kwa maola 4 a sampuli panyumba iliyonse. Ofufuzawo adafufuza zomwe zinasonkhanitsidwa mu fyuluta.
Ngakhale mabanja atatu okha anali amphaka ndi mabanja 2 anali agalu, 20 mabanja Der f 1, 4 mabanja Der p 1, 10 mabanja Can f 1 ndi 21 mabanja Fel d 1 oyenerera kuchuluka.
"Pafupifupi maphunziro onse, mabanja ena anali opanda mite allergener.Ndi njira yathu yabwino, tapeza zosokoneza kulikonse, "atero Butters, pozindikira kuti kuchuluka kwa amphaka kumadabwitsanso.
"Mabanja atatu okha mwa 22 ali ndi amphaka, koma zowawa ndi amphaka zidakali paliponse," adatero Butters.
Chiwerengero cha Der f 1 mlengalenga chinachepetsedwa kwambiri (P <.001) ndi kusefera kwa mpweya, koma kuchepa kwa Der p 1 sikunali kofunika kwambiri, ofufuzawo adanena. chiwerengero chapakati Der p 1 chinatsika ndi 65.5%.
Kusefedwa kwa mpweya kunachepetsanso kwambiri Fel d 1 (P <.01) ndi wapakati wa 76.6% ndi chiwerengero cha Can f 1 (P <.01) ndi wapakati wa 89.3%.
Paulendo wowongolera, wapakatikati Can f1 anali 219 pg/m3 kwa mabanja okhala ndi agalu ndi 22.8 pg/m3 kwa mabanja opanda agalu.Panthawi yoyendera, wapakati Can f 1 anali 19.7 pg/m3 kwa mabanja okhala ndi agalu ndi 2.6 pg. /m3 kwa mabanja opanda agalu.
Paulendo wolamulira, chiwerengero cha FeI d 1 chapakati chinali 50.7 pg / m3 kwa mabanja omwe ali ndi amphaka ndi 5.1 pg / m3 kwa mabanja opanda amphaka. amphaka anali ndi chiwerengero cha 0.9 pg/m3.
Der f 1 ndi Der p 1 zambiri zidapezeka mu ma PM okhala ndi m'lifupi mwake kuposa ma microns 10 (PM> 10) kapena pakati pa 2.5 ndi 10 microns (PM2.5-10) .Zambiri zamphaka ndi agalu zosagwirizana ndi agalu zimalumikizidwanso ndi ma PM a makulidwe awa. .
Kuonjezera apo, Can f 1 inachepetsedwa kwambiri pazigawo zonse za PM ndi zoyezera zowonongeka, ndi kuchepetsa kwapakati pa 87.5% (P <.01) kwa PM> 10 (P <. <.01).
Ngakhale tinthu tating'onoting'ono tokhala ndi ma allergens timakhala mumlengalenga motalikirapo ndipo nthawi zambiri timakokedwa kuposa tinthu tating'onoting'ono, kusefera kwa mpweya kumachotsanso tinthu tating'onoting'ono bwino, kulola ochita kafukufuku kunena.Kusefedwa kwa mpweya kumakhala njira yabwino yochotsera ma allergen ndi kuchepetsa kuwonetseredwa.
"Kuchepetsa zowawa ndi mutu, koma kumapangitsa anthu omwe ali ndi ziwengo kumva bwino.Njira imeneyi yochotseratu ma allergener ndi yosavuta, "adatero Buters, pozindikira kuti kuchepetsa zowawa za mphaka (zomwe amazitcha zachinayi zazikuluzikulu) zimakhala zovuta kwambiri.
"Mutha kutsuka mphaka - zabwino zonse - kapena kuthamangitsa mphaka," adatero."Kusefera kwa ndege kumatero.”
Kenako, ofufuzawo awona ngati odwala matenda ashuga amatha kugona bwino ndi choyeretsa mpweya.
