Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban Institute of Technology, 2005 / Optimal ventilation of the lungs is essential to the function of the human body. Our lungs can be expanded and contracted by the elevation and depression of the ribs. This causes an increase and decrease of the anteroposterior diameter of the chest cavity and the lungs are then expanded by raising the rib cage. There are several different dysfunctions which the ribs are subjected to. These dysfunctions consist of restrictions in either inhalation or exhalation and are associated with increased tone of the intercostals muscles between the ribs. Therefore, if the chest wall movement is restricted in any way, this will cause decrements in pulmonary function and exercise capacity. Furthermore, there is a significant increase in oxygen cost associated with external chest wall restriction, which is directly related to the level of chest wall restriction. Mobilization of the ribs aims to restore mobility and function but no investigations into the immediate effect of rib mobilization on chest wall expansion and lung function have been conducted. Therefore this study aimed to test whether chest wall expansion and therefore lung function can be influenced in ten minutes following a mechanical intervention.

When gas is inspired into the lungs it mixes with the gas left in the lungs at the end of the previous expiration. In health, this mixing is relatively efficient but in disease this gas mixing is impaired. Impairment of mixing is brought about by two processes, a maldistribution of inspired gas into a parallel system, or an inhibition of diffusion. The aim of this thesis was to illuminate the contributions made by these two processes to this impairment. This was done by investigating single and multi-breath alveolar mixing efficiency (AME) in never smokers and patients with chronic airway disease and by the use of mathematical models. Both indices of alveolar mixing efficiencies were found to be reproducible in never smokers and patients, AME(mb) and AME(sb) were both significantly lower in patients than in never smokers. A two-compartment parallel model was devised to evaluate the contribution of regional inhomogeneity. This showed that the only way both values of AME(sb) and AME(mb) could be reproduced was to include a component of diffusion limitation. Another model was devised to evaluate the contribution of diffusion limitation to mixing impairment. This model proved to be inadequate to permit any conclusions. The work presented in this thesis suggests that gas mixing impairment results from a maldistribution of inspired gas and gaseous diffusion limitation with the latter playing the most significant role in the generation of the alveolar slope, more especially in diseased lungs.

Com isso há aumento dos índices de doenças respiratórias nessa espécie, que estão entre as enfermidades que ocasionam maiores perdas econômicas em rebanhos de vários países. Grande parte das doenças respiratórias de mortalidade elevada e sintomatologia clínica evidente está associada a infecções por Mannheimia (Pasteurella) haemolytica. Entretanto, outras enfermidades também acometem os ovinos e são pouco definidas etiológica e morfologicamente, especialmente as de etiologia viral. Os vírus têm sido incriminados como agentes precursores e agravantes quando em associação com infecção bacteriana secundária. Os métodos mais utilizados para identificação viral são a sorologia, isolamento viral, teste de vírus neutralização e reação em cadeia pela polimerase. Contudo, essas técnicas apresentam limitações quanto ao tempo de execução e a necessidade de equipamentos dispendiosos. Com a necessidade da detecção rápida de antígenos virais, métodos como imunofluorescência e ensaios imunoenzimáticos vem sendo mais estudados no diagnóstico de agentes etiológicos. A imunoistoquímica é uma opção para a identificação de diversos agentes etiológicos e vem sendo amplamente estudada nos casos de enfermidades respiratórias, devido a facilidade na execução e não necessitar equipamentos dispendiosos nem técnicas trabalhosas para armazenamento de amostras. Neste contexto, o propósito deste estudo foi avaliar ovinos com comprometimento de vias aéreas anteriores e processos broncopulmonares, detectados no exame clínico e exame histopatológico, e correlacionar os achados com a sorologia, citologia de vias aéreas anteriores e posteriores, com a imunoistoquímica para os Vírus sincicial respiratório... / The economic expansion of sheep breeding cause an increase in the number of animals kept in confinement and increased traffic between these properties, increasing the rates of respiratory diseases in this species, which are among the diseases that cause major economic losses in herds in several countries. Much of respiratory diseases and high mortality evident clinical symptoms are associated with infections by Mannheimia (Pasteurella) haemolytica, however, other diseases also affect sheep and are poorly defined etiology and morphology, especially viral diseases. Viruses have long been incriminated as agents precursors and aggravating when combined with secondary bacterial infection. The methods used for viral identification are serology, virus isolation, virus neutralization test, polymerase chain reaction. However, these techniques have limitations as to time of execution and the need for expensive equipment. With the need for rapid detection of viral antigens, methods such as immunofluorescence and enzyme immunoassays has been most studied in the search for etiologic agents. Immunohistochemistry is an option for the identification of other agents and has been widely studied in cases of respiratory illnesses due to ease of execution and does not require expensive equipment or laborious techniques for sample storage. In this context, the purposes of this research was to evaluate sheep with involvement of upper airways and bronchopulmonary cases, detected on clinical examination and histopathology, and correlate the findings with serology, cytology airways before and after, and immunohistochemistry for Virus Respiratory Syncytial and Parainfluenza virus. Was detected by serology 27.5% for the BIS-3 and 40% for BRSV positive samples. There was a predominance of interstitial pneumonia type (56.7%) and immunohistochemistry detected the presence of BPI-3 antigens in 13.3% and 20.0% ...(Complete abstract click electronic access below)
