Saddex kooxood oo ka mid ah daanyeerka cynomolgus ee ragga ah (Macaca fascicularis) ayaa la kulmay 200 micrograms/m3 ammonium hexachloroplatinate [(NH4) 2PtCl6], 200 micrograms (NH4) 2PtCl6 oo ay la socdaan 1 ppm ozone (O3), ama O3 oo keliya.Xayawaanku waxay la kulmeen neefsasho 6 saacadood maalintii, 5 maalmood usbuucii 12 toddobaad.Naqshadaynta tijaabada ah waxaa ka mid ah methacholine preexposure iyo Na2PtCl6 qiimaynta caqabada bronchoprovocation, Na2PtCl6 imtixaannada maqaarka ee xadka, iyo sera ee falanqaynta unugyada difaaca.Laba toddobaad ka dib 12-wk soo-gaadhista, tusmooyinkan la midka ah ayaa dib loo qiimeeyay.Shaqada aasaasiga ah ee sambabada si weyn uma saameynin hababka soo-gaadhista;si kastaba ha ahaatee, isku darka soo-gaadhista O3 iyo (NH4) 2PtCl6 waxay si weyn hoos ugu dhigtay xoojinta milixda platinum (Pt) iyo methacholine ee lagama maarmaanka u ah in la kordhiyo caabbinta socodka sambabada celceliska (RL) 200% (EC200 RL).Soo-gaadhista Ozone ama Pt keligood wax saamayn ah kuma yeelan xuduudahan.Qiimaha Platinum iyo methacholine EC200 RL ayaa si aad ah ugu xidhnaa labada kooxood ee Pt-soo bandhigay ka dib soo-gaadhista.Xogtaasi waxay muujisay in marka la isku daro soo-gaadhista O3 iyo Pt ay si aad ah u korodhay gaar ahaan (Pt) iyo kuwa aan gaar ahayn (methacholine) boronkiitada hyperreactivity in ka badan marka loo eego soo-gaadhista O3 ama Pt cusbada oo keliya.Isku darka O3 iyo Pt soo-gaadhista ayaa sidoo kale si weyn u kordhisa dhacdooyinka baarista maqaarka ee PT marka la barbar dhigo kooxaha kale ee soo-gaadhista.Si la mid ah waayo-aragnimada aadanaha, baaritaanka radioallergosorbent (RAST) ee unugyada difaaca gaarka ah ee Pt ma ahayn mid xasaasi u ah sida baaritaanka maqaarka ee tooska ah ee lagu aqoonsanayo dadka xasaasiyadda leh.
