Zvinoenderana neongororo yakaburitswa mujenari Clinical and Translational Allergy, inotakurika mhepo yekusefa zvikamu zvakakwana zvakachena zvekutumira mhepo zvinogona kubvisa nemazvo mite, katsi nembwa zvinokonzeresa, uye zvinhu kubva mukati memhepo ambient.
Vatsvagiri vanoidaidza kuti chidzidzo chakakura kwazvo, vachitarisa pane inotakurika yekusefa kwemhepo kune huwandu hwezvinhu zvinofambiswa nemhepo mumakamuri ekurara.
"Makore maviri chidzidzo chisati chaitwa, vaongorori vakati wandei muEurope uye ini takaita musangano wesainzi pamusoro pemhando yemhepo uye allergies," akadaro Jeroen Buters, PharmD, toxicologist, mutevedzeri wemukuru weCentre for Allergy and the Environment, uye nhengo yeGerman Center Munich. Indasitiri Iyo Lung Research Center paYunivhesiti uye Helmholtz Center akaudza Healio.
Vatsvakurudzi vakaongorora Dermatophagoides pteronyssinus Der p 1 uye Dermatophagoides farinae.Der f 1 imba huruva mite allergen, Fel d 1 cat allergen uye Can f 1 imbwa allergen, iyo yose inogona kuonekwa mumhepo inotakura zvinhu (PM) .
“Munhu wese anofunga kuti Dermatophagoides pteronyssinus ndiyo huru inogadzira mite mumhuri.Kwete - zvirinani kwete muMunich, uye pamwe kwete kumwe kumwe.Ikoko kune Dermatophagoides farinae, imwe mite ine hukama hwepedyo.Vanenge vese varwere vakarapwa nezvinyorwa zveD pteronyssinus.Nekuda kwekufanana kwakanyanya pakati pavo, izvi zvaive zvakanaka, "akadaro Butters.
“Zvakare, mite imwe neimwe inorarama zvakasiyana, saka ziva zviri nani kuti ndeipi yauri kutaura nezvake.Kutaura zvazviri, kune vanhu vakawanda muMunich vane hanya naD. farina kupfuura D. pteronyssinus,” akaenderera mberi..
Vatsvakurudzi vakaita kutonga uye kupindira kushanya mumhuri imwe neimwe panguva dzevhiki 4. Munguva yekushanyira kwekupindira, vaimiririra zviitiko zvekuvhiringidza kweguruva nekuzunungusa mutsago kwemaminitsi makumi matatu, chifukidzo chemubhedha kwemaminitsi makumi matatu, uye mubhedha we60 seconds.
Mukuwedzera, vatsvakurudzi vakayera Der f 1 kutariswa mumakamuri ekugara edzimba ina uye vakaona kuti mavhareji epakati aive 63.2% akaderera pane ayo ari mumakamuri.
"Ongororo yeAustralia yakawana akawanda allege mukamuri yekutandarira sofa.Hatina.Takaiwana pamubhedha.Inogona kunge iri yeAustralia-European gradient, "akadaro Butters.
Pakarepo mushure mechiitiko chimwe nechimwe, vatsvakurudzi vakashandura muchenesi uye vakamhanya kweawa 1. Iyi nzira yakadzokororwa kanomwe panguva yekushanya kwega kwega, kwemaawa 4 ekuenzanisira paimba imwe neimwe. Vatsvakurudzi vakabva vaongorora zvakaunganidzwa musefa.
Kunyange zvazvo mhuri nhatu chete dzaive nekatsi uye mhuri mbiri dzine imbwa, mhuri makumi maviri Der f 1, mhuri 4 Der p 1, mhuri gumi Dzinogona f 1 uye mhuri 21 Fel d 1 qualified quantity.
“Muzvidzidzo zvacho zvese, dzimwe dzimba dzaive dzisina mirimo.Nemaitiro edu akanaka, takawana allergens kwese kwese, ”akadaro Butters, achiona kuti huwandu hwekatsi allergens zvakashamisawo.
“Dzimba nhatu chete padzimba makumi maviri nembiri dzine katsi, asi zvinouraya katsi zvichiri kwose kwose,” Butters akadaro.
Zvose Der f 1 mumhepo yakanyanya kuderedzwa (P <.001) nemhepo filtration, asi kuderedzwa kweDer p 1 kwakanga kusiri kwenhamba, vatsvakurudzi vakati. Uyezve, chikamu chepakati cheDer f 1 chakaderera ne75.2% uye iyo yepakati yakazara Der p 1 yakaderera ne 65,5%.
Kusefa kwemhepo kwakaderedzawo zvakanyanya kuderera kweFel d 1 (P <.01) nepakati pe76.6% uye yakazara Can f 1 (P <.01) nepakati pe89.3%.
Munguva yekushanya kwekutonga, iyo yepakati Can f1 yaive 219 pg/m3 kudzimba dzine imbwa uye 22.8 pg/m3 kudzimba dzisina imbwa.Panguva yekupindira kwekushanya, iyo yepakati Can f 1 yaive 19.7 pg/m3 yemhuri ine imbwa uye 2.6 pg. /m3 kudzimba dzisina imbwa.
Munguva yekushanya kwekutonga, iyo yepakati FeI d 1 count yaive 50.7 pg/m3 yedzimba dzine katsi uye 5.1 pg/m3 kudzimba dzisina katsi.Panguva yekupindira kwekushanya, mhuri dzine katsi dzaive nekuverenga 35.2 pg/m3, nepo dzimba dzisina katsi dzaive nekuverenga 0.9 pg/m3.
Zvizhinji zveDer f 1 neDer p 1 zvakaonekwa muPM nehupamhi hunopfuura 10 microns (PM>10) kana pakati pe2.5 uye 10 microns (PM2.5-10) .Mazhinji anokonzera katsi nembwa anobatanidzwawo nePM dzesaizi idzi. .
Mukuwedzera, Can f 1 yakaderedzwa zvakanyanya kumativi ose ePM neine measurable allergen concentrations, nekuderedza kwepakati kwe87.5% (P <.01) ye PM> 10 (P <. <.01).
Kunyange zvidiki zvidiki zvine allergens zvichigara mumhepo kwenguva yakareba uye zvichinyanya kufemerwa kupfuura zvimedu zvakakura, kusefa kwemhepo kunobvisawo zvidimbu zvidiki zvakanyanya, zvichibvumira vaongorori kutaura.Mhepo kusefa inova zano rinoshanda rekubvisa allergen uye kuderedza kuratidzwa.
“Kudzikisira zvinodhaka kunorwadzisa musoro, asi kunoita kuti vanhu vane allergies vanzwe zviri nani.Iyi nzira yekubvisa allergens iri nyore, "akadaro Buters, achiona kuti kuderedza katsi allergens (iyo yaanodaidza yechina yakakura allergens) yakanyanya kuoma.
"Unogona kugeza katsi - rombo rakanaka - kana kudzinga katsi," akadaro." Hapana imwe nzira yandinoziva yekubvisa katsi.Kusefa kwemhepo kunoita."
Tevere, vaongorori vanozoongorora kana vanorwara neallergy vanogona kurara zvirinani neanochenesa mweya.
