Résumé:
This study aimed at evaluating the effects of topical treatment of ethanol extract of Krameria
tomentosa root in skin wounds of sheep. Fourteen Santa Ines female sheep were numbered
and divided into 4 groups according to the treatments. Animals numbered from 1 to 7 had
control treatment on the left side. On the right side, the treatment was conducted with plant
extract at 10%. Animals numbered from 8 to 14 were treated with ointment based on
antibiotic on the left side. The plant extract at 5% was used on the right side for this group.
The treatment was performed on wound everyday and the macroscopic and microscopic
evaluations made conductedweekly. The wounds evaluations were performed through
clinical, morphometric and histopathological points of views in pre-determined periods of
time. Morphometrically, the wounds treated with the plant at 5% showed a higher percentage
of contraction than in other groups in all evaluations. Histopathologically, the wounds of the
treated groups showed better healing than the ones of the control group. The wounds of the
group treated with the extract at 5% showed more total healing characteristics from the 21st
day.
