Effects of PJH on CS/LPS-induced changes in inflammatory cell counts in BALF. A Number of total cells in BALF. B Number of macrophages in BALF. C Number of neutrophils in BALF. CON: control group; CS + LPS group: CS/LPS-exposed; RO group: administration of roflumilast 10 mg/kg prior to CS/LPS exposure; PJH 100 group: administration of PJH 100 mg/kg prior to CS/LPS exposure; PJH 200 group: administration of PJH 200 mg/kg prior to CS/LPS exposure. Results are presented as means ± SD (^#P < 0.05, ^##P < 0.01 compared with the CON group; *P < 0.05, **P < 0.01 compared with the CS + LPS group)
