Idiopathic pulmonary fibrosis waxaa loo maleynayaa inay ku lug leedahay dhaawaca sambabada oo ay keento noocyada ogsijiinta falcelinta (ROS), kaas oo ay ku xigto fibrosis aan caadi ahayn.Qodobka koritaanka isbeddelka ah (TGF) -β1-ku-kordhinta lambarka myofibroblast wuxuu door muhiim ah ka ciyaaraa fibrosis-ka aan caadiga ahayn.Waxaan dhawaan ogaanay in mepenzolate bromide (mepenzolate), oo loo isticmaalay kiliinikada si loogu daweeyo xanuunada caloosha, ay leedahay ROS-yaraynta sifooyinka.Daraasadda hadda jirta, waxaan baarnay saameynta mepenzolate ee fibrosis sambabada sambabada ee bleomycin iyo cillad sanbabada ee jiirarka.Darnaanta fibrosis sambabada waxaa lagu qiimeeyay qiimeynta histopathologic iyo go'aaminta heerarka hydroxyproline.Makaanikada sambabada (elastance) iyo shaqada neefsashada [awoodda muhiimka ah ee qasabka ah (FVC)] ayaa lagu qiimeeyay iyadoo la isticmaalayo hawo-qaade kombuyuutar lagu maamulo.Shaqada neefsiga ayaa sidoo kale lagu qiimeeyay iyadoo la kormeerayo qanjirka oksijiinta halbowlaha ah ee xididada (SpO2).Maamulka intracheal ee mepenzolate ka hor daawaynta bleomycin waxay hoos u dhigtay heerka fibrosis sambabada iyo isbeddelka farsamooyinka sambabada waxayna keentay soo kabashada weyn ee FVC iyo SpO2 labadaba marka la barbardhigo xakamaynta.Intaa waxaa dheer, mepenzolate waxay soo saartay saameyn daweyn xitaa marka la maamulo ka dib horumarinta fibrosis.Maamulka mepenzolate wuxuu kaloo ka hortagay dhimashada unugyada sambabada ee bleomycin-ku keeno iyo jawaabaha bararka iyo kordhinta lambarka myofibroblast.Mepenzolate waxay sidoo kale hoos u dhigtay dhaqdhaqaaqa NADPH oxidase iyo heerka firfircoon ee TGF-β1 ama dhaqdhaqaaqa glutathione S-transferase (GST) oo kordhay iyadoo ay jirto daaweynta bleomycin.Natiijooyinkani waxay muujinayaan in maamulka intratracheal ee mepenzolate ay hoos u dhigtay bleomycin-ku-takoorka fibrosis sambabada iyo sambabada oo aan shaqeynin jiirarka.Saamayntan waxaa laga yaabaa inay sabab u tahay saameynta xannibaadda daawadan ee NADPH oxidase iyo TGF-β1 waxqabadyada iyo saameynta kicinta ee GST.
