Effects of lipopolymers on lung function. Values are means ± SD of eight animals in each group (with 10 determinations per animal). Control group (CTRL) was instilled with vehicle, LIPO group was instilled with the lipopolymer only, and the ARG, TRP, and CYS groups were instilled with the lipopolymer containing l-arginine, l-tryptophan, and l-cysteine, respectively. (A) Lung static elastance (Est,L). (B) Stacked bar chart: the data in each gray bar represent the lung viscous pressure (ΔP1) and the white bars are viscoelastic/inhomogeneous (ΔP2) pressure dissipation. The whole column represents the total pressure (ΔPtot) variation in each group.
