Caracterização da variação do calibre das fibras musculares, densidade capilar e expressão de miosina neonatal nos músculos masseter e temporal / Characterization of the variety on cross sectional area, capillary density and neonatal myosin expression in the masseter and temporalis muscle

Mariana Brandão Ferreira 21 October 2009 (has links)
A Disfunção temporomandibular (DTM) é um termo coletivo que abrange um largo espectro de problemas clínicos da articulação e dos músculos na área orofacial; estas disfunções são caracterizadas principalmente por dor, sons na articulação, e função irregular ou limitada da mandíbula. Os músculos da mastigação podem estar envolvidos na DTM de origem muscular, e por definição são os músculos que promovem o toque dental, portanto os elevadores da mandíbula: masseter, temporal, pterigóideos medial e lateral. A origem muscular da DTM é a mais prevalente, sendo portanto,o entendimento funcional e estrutural da composição dos músculos da mastigação essencial para a compreensão desta DTM. Este estudo tem como objetivo analisar a estrutura dos músculos da mastigação quanto a variação do calibre das fibras lentas e rápidas, densidade capilar e da expressão da miosina neonatal com a variação da idade. Foram estudadas 37 amostras dos músculos temporal e masseter (20 amostras do sexo masculino e 17 do sexo feminino) de autópsias do Serviço de Verificação de Óbitos de São Paulo com intervalo pós-mortem de até 18 horas, de ambos os gêneros e com idades divididas por décadas (1a a 9a décadas). Foram realizadas reações imunoistoquímicas com os anticorpos Ulex europaeus biotinilada aglutinina, anti-miosina neonatal, anti-miosina rápida, anti-miosina lenta para análise da expressão das proteínas. A avaliação foi feita por dois observadores, após calibração intra observador, (duas contagens no mesmo campo pelo mesmo observador em tempos diferentes) e inter observador (contagem do mesmo campo por dois observadores), até se atingir uma margem de erro menor que 10%. Em relação ao número de capilares/fibra, nos músculos masseter e temporal, da primeira a nona década, em média respectivamente foi de 1 e 0,7 respectivamente. O número de capilares por mm², nos músculos masseter e temporal, não variou ao longo das nove décadas estudadas, e o número de capilares por mm², foi significantemente maior no músculo masseter quando comparado ao temporal, (p=0,025). A miosina neonatal manteve-se presente embora com decréscimo em todas as décadas dos músculos masseter e temporal. Observou-se o diâmetro das fibras do tipo II menores que as fibras do tipo I / Temporomandibular disfunction (TMD) is a colletive term that refers to different clinical problems of the temporomandibular joint and the jaw muscles. These disfunctions are characterizied meanly by pain, joint sounds and irregular or limited mandibular function. The jaw muscles can be involved in the TMD of muscle etiology, and by definition they are the ones which provide the teeth touch, then the jaw elevators: masseter, temporalis, medial pterygoid and lateral pterygoid. As the muscular etiology is the most prevalent cause of TMD, the detailed understanding of structural and functional composition of the masticatory muscles is paramount to better comprehend TMD due to muscle disorder. This study has the aim to analyze the jaw muscle structure concerning capillarie density, neonatal myosin expression, and the cross sectional area of the fast and slow fibers in temporalis and masseter muscles in autopsy samples from 1st to 9th decades of age. Thirty seven temporalis and masseter muscles samples were studied (20 from male and 17 from female) from Serviço de Verificação de Óbitos of São Paulo. The specimens were divided by gender and ages. The samples were collected up to 18 hours post-mortem. Imunohistochemistry stainning were made with antibodies to analize the protein expression. The evaluations were made by two observers, after intra observer calibration (two evaluations on the same field by the same observer in different times) and inter observer (evaluation of the same field by two observers), unti getting less than 10% of error. The number of capillaries per fiber in the masseter and temporalis muscle was in average 1 and 0,7 respectively. The number of capillaries per mm² was significantly higher in the masseter when compared to temporalis muscle (p=0.025). The neonatal myosin was present in all decades in both muscles, and it was observed that the cross sectional area of the type II fibers was smaller than the type I fibers

Immunoglobulin VH gen analys in human B-cell

Heidari, Ramesh January 2006 (has links)
Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells. Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgVн) of MALT lymphomas. Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis. Successful amplification was seen in 10/13 cases and sequences of IgVн genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the Vн3 family, 2 from Vн1 and 1 from the Vн 4 family.
