Lung mechanics and lung inflammation. The mean and standard error (SE) of respiratory system elastance (Ers) a and lung tissue elastance (Htis) b evaluated using a Flexivent ventilator under anesthesia 28 days after elastase or saline instillation. After the lung mechanics were evaluated, the animals were exsanguinated, and bronchoalveolar lavage fluid was collected. We quantified total cells c, macrophages d, lymphocytes e, neutrophils f and eosinophils g in the four groups. SAL+Ve: control group with vehicle treatment; ELA+Ve: elastase instillation and vehicle treatment; SAL + SK: control group treated with sakuranetin; ELA+SK: elastase- and sakuranetin-treated group. *p < 0.05 compared with the control (SAL+Ve and SAL+SK); **p < 0.05 compared with the ELA+Ve group
