The dose-effect relationship between polydatin and cPLA ₂ mRNA expression in rat lung. A. cPLA₂ mRNA expression in PD treatment groups with different doses by real-time PCR. B. cPLA₂ mRNA expression in PD pretreatment groups with different doses by real-time PCR. ^cP < 0.01 vs. 1 mg·kg^-1 PD group, ^eP < 0.05 and ^fP < 0.01 vs. 5 mg·kg^-1PD group, and ⁱP < 0.05 vs. 10 mg·kg^-1 PD group.
