Figure 6.

Effect of PTP on arachidonic acid-induced mouse ear edema and MPO activity. Representative images of mouse ears and H & E staining for each experimental group (a). Ear thickness in HPF was measured with the ImageJ software (b). MPO enzymatic activity quantification in response to PTP application (c). The control group was treated with vehicle and AA. All values are reported as the mean ± SD. # indicates a significant difference from the vehicle group (##P < 0.01). ^∗ indicates a significant difference from the AA control group (^∗P < 0.05, ^∗∗P < 0.01). PTP: Pinus thunbergii Parl.; DEX: dexamethasone; IBU: ibuprofen, AA: arachidonic acid; MPO: myeloperoxidase; HPF: high-power field.
