Effects of polydatin on the expression of sPLA ₂ /cPLA ₂ mRNA in rat lung. A. Relative expression of sPLA₂, quantified by real-time PCR. B. Relative expression of cPLA₂, quantified by real-time PCR. I: sham operation group, injected with normal saline; II: endotoxic shock group, injected with LPS (10 mg·kg^-1 body weight); III: PD treatment group, injected with LPS (10 mg·kg^-1 body weight), then a 0.5% PD solution (0.2 ml·kg^-1 body weight) 1 hour later; IV: PD pretreatment group, injected with a 0.5% PD solution (0.2 ml·kg^-1 body weight), then LPS (10 mg·kg^-1 body weight) 0.5 hours later; V: PD control group. ^bP < 0.05 and ^cP < 0.01 vs. group I; ^fP < 0.01 vs. group II; ⁱP < 0.05 and ^jP < 0.01 vs. group III.
