The efficiency of the topical use of a commercial product constituted by a herbal combination on the healing evolution of equine induced wounds was studied. A skin lesion in the shape of a square with 5cm sides was surgically produced on both sides of the buttocks of eight adult horses. One side was considered control and another one treated. Both control and treated sides were rinsed with water and neutral soap. Additionally, the wound on the treated side received the topical treatment with the herbal combination. Macroscopic and microscopic healing evolution of the wounds was evaluated and their areas were determined during the experimental period. There was statistical difference between wound areas. At the last evaluation, the average area of the control side was 0.70cm² and of the treated side was 1.23cm². The contraction of scar observed at 77 days was 97.57% for the control side and 95.59% for the treated side.

The present study aimed to evaluate cardiac and lipoperoxidation markers in horses subjected to low intensity and long duration (TLD) exercise test, before and after vitamin E supplementation. For this purpose, 10 horses were used, subjecting them to the first TLD with a workload based on individual maximal oxygen uptake (VO2max). Then, horses received vitamin E (dl-alpha-tocopherol) during 59 days at a daily oral dose of 1,000IU, and thereafter they performed a second TLD with the same protocol as the first. Blood samples were collected to determine plasma malondialdehyde (MDA) as an index of lipoperoxidation, serum cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) as cardiac markers. As a result of the exercise, there was no significant increase in MDA or cTnI, but serum CK-MB increased suggesting myocardial stress. The supplementation was able to minimize reactive oxygen species production, as evidenced by lower concentrations of MDA at all times evaluated, but it didn't cause protective effect on the myocardium. It was concluded that the low intensity and long duration exercise promoted light myocardial stress in horses and vitamin E supplementation reduced lipoperoxidation.

Avaliou-se a resposta de fase aguda através da concentração das proteínas de fase aguda (PFA) no soro sanguíneo e no líquido peritoneal de vinte e um equinos, hígidos e submetidos à obstrução intestinal experimental, distribuídos em quatro grupos: obstrução de duodeno - GD (n=6), íleo - GI (n=6), cólon dorsal esquerdo - GM (n=6) e controle instrumentado - GC (n=3). Foram colhidas amostras de sangue e líquido peritoneal e, após centrifugação e fracionamento, as proteínas de fase aguda foram separadas por eletroforese em SDS-PAGE. Identificaram-se as proteínas IgA, ceruloplasmina, transferrina, albumina, IgG, haptoglobina, α1-glicoproteína ácida e P24, no soro e no líquido peritoneal. Houve aumento nas concentrações sérica e peritoneal de todas as PFA, sendo mais evidente no líquido peritoneal e nos animais obstruídos. O fracionamento eletroforético das PFA no líquido peritoneal é mais eficaz no diagnóstico de processos inflamatórios abdominais, quando comparado ao sérico.
