Abstract

Objective. The objective of the present study was to evaluate the in vivo wound healing effect of water extract of Tetrapleura tetraptera in stem-bark. Method: The healing activity was studied in 40 male rats using excision and incision wounds on normal and dexamethasone-suppressed wound healing. For each model, rats were divided in 4 groups as follows: control, dexamethasone, T. tetraptera and dexamethasone combined with T. tetraptera. Results: Data recorded exhibited a significant effect by the extract in the epithelialization time within 14 and 18 days of the normal and dexamethasone-induced healing delay rats respectively (p<0.05). The extract also significantly increased the wound tensile strength in dexamethasone treated rats. Histological examination of incision wounds of extract-treated group showed many fibroblasts and the same rats presented significant cutaneous tensile strength, suggesting important collagen crosslinkage. Conclusion: This study illustrated an excellent potential of the bark of T. tetraptera therapy on dermal wound healing with a possible mechanism of action related to epithelialization, contraction and tensile strength improvement.
