Morphoquantitative description of bovine digital cushion / Descrição morfoquantitativa do tórus digital de bovinos

The digital cushion is characterized as a modified subcutaneous tissue that absorbs the shock 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 4µm 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...

O tórus digital é caracterizado como um tecido subcutâneo modificado que atua na absorção do impacto durante a locomoção, auxilia o retorno venoso do casco e mantêm o suporte de uma considerável parte do peso corporal. Os tórus possuem particular importância nas patogêneses de casco, já que eles precisam trabalhar corretamente para prevenir compressões e traumas nos tecidos moles. Assim, o objetivo deste estudo foi quantificar e com isso determinar, como se arranjam estas estruturas, para tanto, foram estabelecidas as proporções dos tecidos conjuntivo, adiposo, vascular e ainda das fibras colágenas e dos tipos de colágenos encontrados nos tórus digitais palmares e plantares de bovinos. Foram utilizados membros torácicos e pélvicos de doze bovinos zebuínos adultos, de ambos os sexos, sendo onze machos e uma fêmea, com peso médio de carcaça com 269kg e sem afecções nos membros. Os fragmentos dos tórus foram submetidos à técnica histológica convencional, cortados em espessura de 4µm e corados com Picrosirius Red. Com o uso de microscópio óptico digital, o tecido conjuntivo e a diferenciação dos tipos de colágeno foram quantificados empregando-se o programa de análise de imagem Image Pro Plus® e para a quantificação dos tecidos adiposo e vascular foi utilizada o sistema teste de pontos. Através do programa GraphPad Prism 5.0 foram obtidas por meio de uma analise descritiva a media e o erro padrão da media, em seguida os dados foram submetidos à aplicação do teste de normalidade de Kolmogorov-Smirnov e ao teste "T" Student com nível de significância de 5% para a determinação da quantidade encontrada dos diferentes tecidos entre os membros torácicos e pélvicos dos animais estudados. Nos membros torácicos a média e o erro padrão da proporção de tecido conjuntivo foi de 50,10%+1,54, a de tecido adiposo foi de 21,34%+1,44 e a de tecido vascular foi de 3,43%+0,28. Os membros pélvicos...

Comparative study of skin folding of dominant and nondominant hemibodies in spastic hemiplegic cerebral palsy

OBJECTIVE: To compare skin folds in the dominant and nondominant halves of the body in a group (A) of 20 individuals with cerebral palsy and spastic hemiplegia and a group (B) of 30 normal volunteers. METHOD: Body mass, height and skin folds were measured, and the percentage of body fat was estimated by adipose tissue measurement and densitometry. The mean age in group (A) was 24.6 ± 5.6 years (ranging from 16.1 to 38.1 years). The mean age in group (B) was 25.3 ± 3.8 years (ranging from 19.0 to 34.11 years). RESULTS: Statistically significant differences were observed between the dominant and nondominant halves of the body for biceps, triceps, thoracic, suprailiac, thigh and midcalf skin folds in group A; the biceps, subscapular, midaxillary, suprailiac, abdominal, thigh and midcalf skin folds in group B; and the percentage fat obtained by adipose tissue measurement in both groups. Statistically significant differences were observed for the triceps skin fold when the dominant halves of the body in groups A and B were compared. Statistically significant differences were also observed for the biceps, triceps, thigh and midcalf skin folds as well as the adipose tissue measurements between the dominant and nondominant halves of the body in the two groups. The percentage fat as estimated by densitometry was significantly correlated with the adipose tissue measurement. CONCLUSION: There were statistically significant differences between the skin folds in the dominant and nondominant halves of the body, both in group A and in group B (greater in group A). There was a statistically significant correlation in the percentage fat as estimated by densitometry and as measured by adipose tissue in groups A and B.

A study on the facial morphometry of the attractive Uygur females in Xinjiang / 实用口腔医学杂志

Objective:To obtain the normal values of the facial soft tissue measurements of the attractive Uygur females in Xinjiang by photogrammetric analysis,and to study the relationship between the facial feature of attractive Uygur females and the neoclassical canons. Methods:31 attractive Uygur women were selected, standardized and referenced frontal photographs of faces were taken,and 14 standard anthropometric marks were determined,then measurements were performed by photoshopCS software.Results:Intercanthal width was rather smaller than nose width and larger than eye fissure width;nose width occupied more than 1/4 of face width or 2/3 of mouth width.The chin occupied 2/3 of the entire mandibular height.There was positive correlation among many horizontal and vertical facial soft tissue measurements.Conclusion:The facial features of the attractive Uygur females in Xinjiang fit the classical facial canons to some extent. There is pertinence in attractive facial form and features.
