Fig. 1From: An inactivated Pseudomonas aeruginosa medicament inhibits airway allergic inflammation and improves epithelial functionsLung resistance (R L) assay induced by different concentrations of hydrochloric acid histamine. OVA resulted in increased R L to hydrochloric acid histamine (at the concentrations of 0.16 and 0.32 mg mL−1) and PPA abolished the increased R L induced by hydrochloric acid histamine (n = 6, *P < 0.01 vs. OVA plus PPA)Back to article page
