Resumen
The study aimed to evaluate the healing activity of the powdered pod of L. ferrea in cutaneous wound healing in preclinical test in rats. Eighteen rats were divided into two groups: the positive control group (PCG) treated with Kollagenase® and the experimental group (EG) treated with an ointment prepared with the powder of Libidibia ferrea. The lesions were clinically evaluated on 0 - 21st days, when histopathological analysis was also performed. In this study, the clinical analysis showed that although the rate of contraction of the lesions in EG was lower than in PCG, there was significant reduction in the wound of the group treated with ointment obtained from the powder of L. ferrea. Furthermore, the morphometric data showed that from the 3rd to 21st day after operation, the EG presented significant reduction in the rate of contraction of the skin lesions. Histological analysis revealed that the clinical and histological parameters of EG were similar to PCG. Although the biological activity of the powder remains unclarified, our results clearly showed the wound healing with the use of the powder of the pod of Libidibia ferrea in skin lesions. These finds provide subsidies for a similar research.
