The present study was designed to identify and compare the in vivo wound healing capacity of a bark extract from Pinus brutia and Pycnogenol in an incision wound model in rats. O/W cream formulations were prepared incorporating 2% Pycnogenol and P. brutia bark extract. The rats were divided into three groups (n = 8). Subsequently placebo and test formulations were applied to animals once a day from day "0" until the 9th day. Malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were studied in addition to histopathological examinations. Treatment with F. brutia extract containing cream inhibited lipid peroxidation by a 35% decrease in MDA and 46.8% increase in SOD activity, whereas 19.3% decrease in MDA and 34.7% increase in SOD activity were attained with Pynogenol compared to control. The histological data revealed a better performance of P. brutia extract enriched formulation in terms of degeneration of hair roots, increased vascularization and a decrease in necrotic area. Consequently, a high wound healing activity was observed in animals treated with P. brutia extract significantly accelerating the wound healing process.
