The digital cushion is characterized as a modified subcutaneous tissue that absorbs theshock during gait, assists venous return of the hoof and supports a considerable part of body weight. Digital cushions have particular importance in the pathogenesis of the hoof, since they need to properly work in order to prevent compression and traumas in soft tissues. This study aimed to measure and determine how is the arrangement of these structures, and for this it was established the proportions of connective, adipose, vascular tissues and collagen fibers and collagen types found in palmar and plantar digital cushion of bovine using fore and hindlimbs of twelve adult zebu cattle of both sexes, 11 male and one female, with 269kg average carcass weight and without limb disorders. Fragments of cushions were subjected to conventional histology, cut to a thickness of 4?m and stained with Red Picrosirius. With digital optical microscope, the quantification of the connective tissue and differentiation of types of collagen used the Image Pro Plus® software, and of adipose and vascular tissue, the test point system. The mean and standard error were estimated with the GraphPad Prism 5.0 software, and then data were subjected to Kolmogorov-Smirnov normality test and Student?s t-test with significance level set at 5% for determining the amount of different tissues between fore and hindlimbs of studied animals. In forelimbs the mean and standard error of the connective tissue proportion was 50.10%+1.54, of the adipose tissue was 21.34%+1.44, and of vascular tissue was 3.43%+0.28. Hindlimbs presented a proportion of connective tissue of 61.61%+1.47, 20.66%+1.53 of adipose tissue, and 3.06%+0.20 of vascular tissue. A significant difference (p<0.001) was detected in the connective tissue proportion between fore and hindlimbs. Types I and II collagen fibers have presented, respectively, a proportion of 31.89% and 3.9% in forelimbs and 34.05% and 1.78% in hindlimbs. According to the used methodology, digital cushions had a clear differentiation relative to adipose tissue between fore and hindlimbs.

O presente trabalho teve por objetivo comparar dois métodos de avaliação e análise da resistência à geada de mudas de Eucalyptus viminalis Labill., consistindo de: (a) classificação das mudas em seis classes: 0 = muito, até 5 = não afetada pela geada, simulada em um fitotron. As mudas com notas de 0, 1, e 2 foram reclassificadas como 0 = severamente afetadas e aquelas com notas 3, 4 e 5, como 1 = ligeiramente afetadas, com os dados analisados pelo teste x2; (b) resistência à geada avaliada pelo conteúdo de umidade das mudas, após o teste frio, com os valores transformados em Y = x + 0,5 e analisados pelo teste F, análise de variância. Os resultados evidenciaram uma eqüivalência de interpretações, indicando que o método (a) deveria ser preferido sobre (b), nos casos em que não se tem interesse por estudos de prognose. |
