Avaliação da atividade cicatrizante do jucá (Caesalpinia ferrea Mart. ex Tul. var. ferrea) em lesões cutâneas de caprinos

O objetivo deste estudo foi demonstrar os efeitos do tratamento topico do juca (Caesalpinia ferrea) em feridas cutâneas. Quinze caprinos machos sem raca definida foram divididos em 3 grupos de acordo com o pos-cirurgico (7o, 14o e 21o dias). As feridas experimentais foram tratadas com a pomada composta pela casca da Caesalpinia ferrea em po misturada com a vaselina esteril e as do grupo controle apenas com a vaselina esterilizada. A aplicacao diaria da pomada e da vaselina esteril foi realizada sobre ferida circular padronizada de 16 cm² de area na regiao toracica de cada animal. As avaliacoes das feridas foram feitas do ponto de vista clinico, bacteriologico, morfometrico e histopatologico nos periodos pre-determinados (7o, 14o e 21o dias). Morfometricamente, as feridas do controle apresentaram areas cirurgicas menores e grau de contracao maior que as do grupo tratado, entretanto, histologicamente, houve completa epitelizacao das feridas tratadas no 21o dia, enquanto que as feridas do grupo controle necessitavam de mais tempo para resolucao do processo cicatricial. No exame microbiologico realizado no momento da producao da ferida, nao se observou crescimento bacteriano e no momento das biopsias, identificou-se a presenca de bacterias da familia Enterobacteriaceae e Staphylococcus aureus, sendo que a partir do 14o dia observou-se Staphylococcus aureus apenas no grupo controle. A utilizacao topica da pomada de Caesalpinia ferrea apresentou eficiencia significativa no auxilio da reparacao cicatricial de feridas cutâneas de caprinos. The aim of this study was to demonstrate the effects of the topical treatment with Brazilian ironwood (Caesalpinia ferrea) on cutaneous wounds. Fifteen male mongrel goats were divided into 3 groups according to the postoperative period ((7th, 14th and 21st days). The experimental wounds were treated with an ointment composed of Brazilian wood powder bark mixed with sterile vaseline, whereas controls were only treated with sterile Vaseline. The ointment and the sterile vaselin were daily applied on a standardized circular wound (16 cm² area) in the thoracic region of each animal. Clinical, bacteriological, morphometric and histopathological evaluations were performed in the wounds at predetermined periods (7th, 14th and 21st postoperative days). Morphometrically, control wounds had smaller surgical areas and greater degree of contraction than those from the treated group. However, histologically, there was a complete epithelialization of the treated wounds on the 21st day, whereas control wounds required longer time for healing. In the microbiological evaluation performed at the moment of wound production, there was no bacterial growth. During biopsies, Enterobacteriaceae bacteria and Staphylococcus aureus were identified; from the 14th day, the latter was only observed in the control group. The topical use of Caesalpinia ferrea ointment was significantly efficient to help healing cutaneous wounds in goats.
