RESUMO
This study aimed to evaluate the anti-inflammatory and repair effects of the ethanolic extract and ointment of Equisetum pyramidale on the skin lesions of rats induced to diabetes. After the induction of diabetes with alloxan, a surgical procedure was performed on the back of each rat. Then, they were separated into treatment groups: G1 ethanol extract of E. pyramidale; G2-ointment (extract of E. pyramidale 80g + 20g of vaseline:lanolin 1:1); G3 control (vehicle vaseline:lanolin 1:1); and G4-no treatment during 3, 7 and 14 days. The samples were embedded in paraffin and stained with hematoxylin-eosin for histological analysis. The findings showed that the use of ethanolic extract as well as the ointment decreased the inflammatory cells at the site of inflammation, resulting a faster healing, with less crusting and lower amount of secretion in comparison to the control group. Therapy with topical herbal was an effective method in the inflammatory process of tissue repair, contributing to a faster and more organized tissue re-epithelialization.
