Airway inflammation as determined by analysis of (a) bronchoalveolar lavage fluid (BALF) and (b) airway hyper-responsiveness in OVA/SNPs asthma models. *P<0.05 between two variables; #P<0.05 compared with others. M-SNP, mesoporous silica nanoparticle; OVA, ovalbumin; P-SNP, PEGylated silica nanoparticle; RL, Resistance of lung; S-SNP, spherical silica nanoparticle.
