The aim of this study was to evaluate the effects of 10% copaiba oil in experimentally induced wounds in horses. Four wounds were made in the lumbar and metacarpal regions of eight adult horses. In the treatment group, the wounds received 10% copaiba oil and in the control group 0.9% sodium chloride, in the daily dressing for 21 days. The wounds were evaluated three, 7, 14, and 21 days postoperatively. No significant differences were observed between the groups. The mean lumbar wound contraction rates were 80.54% and 69.64%, for the control and treated groups, respectively. For the wounds in the metacarpal region, these averages were 44.15% and 52.48%, respectively. Under the experimental conditions of the present study, it is concluded that 10% copaiba oil has beneficial in wound healing in the equine species and suggest that copaiba oil can be used as a therapeutic possibility in equine wound therapy.

This study consists of a checklist and an analysis of the spatial distribution of the species of Orchidaceae of the Brazilian state of Santa Catarina. Based on literature, the accepted names and current synonyms for the species in the state are cited. The occurrence of 121 genera and 560 accepted species was detected, 12 of them endemic. Of the three subfamilies represented in the state, Epidendroideae is the most representative, with 94 genera and 432 species, followed by Orchidoideae with 25 genera and 122 species, and Vanilloideae, with only two genera and six species. According to the criteria of the International Union for Conservation of Nature, 24 species fall within the vulnerable category, seven are endangered and four are critically endangered. The life form, plant formation and habitat of each species are also presented.
