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.

Propomos uma metodologia para avaliação de impactos das mudanças climáticas na demanda de água para irrigação em nível de bacia hidrográfica, utilizando integração de modelos, na Bacia do Jaguaribe, no Estado do Ceará. Foi empregado o sistema integrado de modelagem regional Providing Regional Climates for Impact Studies (Precis), submetido ao método de redução de escala dinâmica, utilizando-se o modelo climático regional HadRM3P com as condições de contorno do modelo global HadAM3P, do Hadley Centre. Foi utilizado um conjunto de climatologia de base do modelo de 1961 a 1990 e de projeções climáticas futuras (2040) com resolução de 0,44º x 0,44º. As coordenadas geográficas da região em estudo foram consideradas para interpolação, num sistema de informação geográfica abrangendo área de 6.415,10km2. A evapotranspiração de referência foi estimada pelo método simplificado de Penman-Monteith FAO, utilizando-se dados mínimos. O aumento da necessidade hídrica bruta média foi estimado em 33,62% e 37,87% respectivamente para o ano de 2040, conforme o cenário analisado (A2 e B2). |
