Figure 2. Pentoxifylline treatment inhibits collagen deposition.

(A) Representative images of HE staining. No adhesion was observed in the sham group. Severe liver or bowel adhesion were observed in the PA group, whereas the PTX treated group had decreased adhesion severity. (B) Representative images of Picrosirius red staining. The thickness of the collagen deposition was increased in the PA group, whereas the PTX treated group has less collagen deposition. (Original magnification, x200, bar = 100 µm).
