a Effect of dexamethasone on pleural fluid volume after induction of hydrothorax. The remaining pleural fluid volume (μL) of the retention volume group and the untreated and dexamethasone-treated group of mice 2 and 4 h after the induction of isosmotic hydrothoraces of 500 μL. b Effect of dexamethasone on pleural fluid absorption rate after induction of hydrothorax. The pleural fluid absorption rate (μL/min) of the untreated and dexamethasone treated group of mice 2 and 4 h after the induction of isosmotic hydrothoraces of 500 μL. Values are mean ± SEM. Bars *p < 0.05 vs 2 h untreated group, **p < 0.05 vs 4 h untreated group, ^$p < 0.05 vs 2 and 4 h untreated groups
