Atividade sérica das enzimas musculares em muares submetidos à prova de resistência de 100 km / Serum activity of muscular enzymes in mules after a 100 km endurance exercise

O presente estudo teve por objetivo avaliar a influência do exercício físico de intensidade submáxima sobre as concentrações séricas de aspartato aminotransferase (AST), creatinoquinase (CK) e lactato-desidrogenase (LDH) em muares durante prova de enduro de 100 km realizada no estado do Espírito Santo. Para tal foram obtidas amostras de soro de 20 muares em três momentos assim definidos: no repouso (T0); após 54 km de percurso (T1); após 80 km de percurso (T2); e após 100 km de percurso (T3). As referidas amostras foram encaminhadas ao Laboratório Clínico Veterinário (CEMEVES) para processamento. Na avaliação da atividade sérica de AST, os valores médios registrados nos momentos T0, T1, T2 e T3 foram, respectivamente, de 341,7±73,9 UI/L, 403,1±78,4 UI/L, 410,5±70,5 UI/L e 426,5±66,7 UI/L. Na avaliação da atividade sérica da LDH, os valores médios registrados foram de 423,1±101,8 UI/L, 534,4±131,8 UI/L, 628,5±100,6 UI/L e 823,4±273,2 UI/L, respectivamente, nos momentos T0, T1, T2 e T3. Por fim, na avaliação da atividade sérica da CK os valores de mediana foram de 231,3 UI/L, 310,6 UI/L, 253,2 UI/L e 476,0 UI/L, respectivamente nos momentos T0, T1, T2 e T3. A análise dos resultados demonstrou que o exercício físico imposto levou ao aumento significativo das atividades séricas de AST e LDH e não alterou as concentrações séricas de CK.

The aim of this study was to evaluate the influence of an exercise of submaximal intensity on serum concentrations of aspartate aminotransferase (AST), creatine kinase (CK) and lactate dehydrogenase (LDH) in mules during endurance exercise in Espirito Santo, Brazil. Serum samples were obtained from 20 mules in four different moments: at rest (T0); after 54 km (T1); after 80 km (T2); and after 100 km (T3). Samples were analyzed at Laboratório Clínico Veterinário (CEMEVES). Serum AST analysis revealed mean values of 341.7±73.9 UI/L, 403.1±78.4 UI/L, 410.5±70.5 UI/L and 426.5±66.7 UI/L, respectively at moments T0, T1, T2 and T3. LDH mean values recorded in T0, T1, T2 and T3 were, respectively, 423.1±101.8 UI/L, 534.4±131.8 UI/L, 628.5±100.6 UI/L and 823.4±273.2 UI/L. Finally, when evaluating CK, median values recorded were 231.3 UI/L, 310.6 UI/L, 253.2 UI/L and 476.0 UI/L, respectively on the moments T0, T1, T2 and T3. Results showed that the physical exercise imposed leaded to significantly increase in serum AST and LDH and did not change serum CK.

[Prevalence and control of gastrintestinal parasitosis in calves from dairy farms in the municipality of Alegre, Espírito Santo]. / Prevalência e controle das parasitoses gastrintestinais em bezerros de propriedades leiteiras no município de Alegre, Espírito Santo.

The objectives of the present study were to evaluate the prevalence of gastrintestinal helminthosis of calves and to identify control aspects related to these infections in dairy farms of the municipality of Alegre, Espírito Santo. A total of 222 calves varying of one to 18 months of age were examined and proportionally divided between 12 dairy farms. After techniques in the laboratory of parasitic diseases of the veterinary hospital of Centro de Ciências Agrárias of the Universidade Federal do Espírito Santo, the prevalence of eggs of Strongyloidea, Trichuris sp., Moniezia sp, Strongyloides papillosus and coccidial oocysts were, in properties and calves: 100 and 66; 100 and 57.8; 50 and 8.2; 25 and 1.8, and 33.3 and 7.8%, respectivelly. Of the 66 for eggs of the Strongyloidea, 64 were attributed to Haemonchus spp. and 53.75% to Cooperia spp. Despite the existence of parasite control programs in the farms, were identify some wrong practices, as lack of weighting animals for the calculation of the dose rate of the drugs and lack of use of the compost of excrements. Thus, the drugs uses of incorrect form may be able to cause future damages with development of parasites resistance to these products.
