Sumario: | 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. MATERIALS AND METHODS: 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 four 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 the 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. |
