OBJECTIVE
This study tested the ability of pycnogenol, an extract from the bark of the French maritime pine (Pinus pinaster), to prevent intra-abdominal adhesions.
METHODS
Thirty female Wistar albino rats were separated randomly into three equal groups: Group (1) the control group, which underwent surgery, but was given no drug; Group (2) given 10 mg/kg of pycnogenol dissolved in normal saline intraperitoneally for 10 days after surgery; and Group (3) given 0.1 mL of normal saline for 10 days intraperitoneally after surgery. On post-operative day 10, all of the animals were killed and any adhesions were evaluated macroscopically and histopathologically.
RESULTS
The macroscopic adhesion scores (mean ± SD) for Groups 1, 2, and 3 were 2.5 ± 0.53, 0.60 ± 0.70, and 2.0 ± 0.82, respectively. The macroscopic adhesion score was significantly lower in Group 2 than in Groups 1 and 3 (p < 0.001). All three components of the histopathological evaluation (inflammation, fibrosis, and neovascularization) were significantly lower in Group 2 than in Groups 1 or 3 (p < 0.001, p < 0.001, and p = 0.004, respectively).
CONCLUSIONS
Pycnogenol was found to be effective at preventing surgery-related adhesions in an animal model.
