The dose-effect relationship between polydatin and cPLA
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.
