Pinus thunbergii Parl. Extracts Reduce Acute Inflammation by Targeting Oxidative Stress

Figure 2

Effect of PTP on LPS-induced NO (a) and iNOS (b) production in RAW 264.7 macrophages. The NO generation values are reported as % activity relative to the control. To measure iNOS production, cells were pretreated with PTP (25, 50, and 100 μg/ml) or DEX (5 μg/mL), then treated with LPS (0.1 μg/mL). iNOS relative density was analyzed using densitometry. All values are reported as the mean ± SD. indicates a significant difference from the negative control group (). indicates significant difference from the positive control group (, ). PTP: Pinus thunbergii Parl.; DEX: dexamethasone.
