Figure 5. Pentoxifylline treatment reduced inflammation.

(A) Immunohistochemistry for F4/80 was performed on mice peritoneal tissue in the different groups at day 3 and day 7. The F4/80 expression was increased in the PA group. Representative images of the sham group, the PA group, and the PA+PTX group are shown (Original magnification, x200, bar = 100 µm). (B) Quantification of F4/80⁺ cells (%) in high-powered field (HPF) at x400 magnification. Data are expressed as the mean± SE. ^∗P < 0.05, ^∗∗P < 0.01, ^∗∗∗P < 0.001, respectively.
