Dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in fulfillment of the requirements for the degree of Master of Science in Anatomical Sciences. / Due to paucity of free respiratory macrophages (FRMs), compared with mammals, birds have been alleged to be more susceptible to pulmonary infections and affliction. The goal of this study was to question or validate this speculation. Twenty-two mature healthy chickens, 24 domestic ducks and 20 rats were used in various experiments. After pulmonary lavage, FRMs were stained with trypan blue for cell count and with neutral red and trypan blue to assess cell longevity. The cell dynamics was determined by counts made on serial lavages. The morphological attributes of the FRMs and that of the respiratory “phagocytic epithelium” were quantified stereo logically. The rat had a significantly greater number of macrophages and the surface density of the filopodia of the FRMs was higher than that of the birds. The volume density of the vesicular bodies of the macrophages in the three groups of animals was not significantly different. Putative cell flux onto the respiratory surface was observed in the birds and not in the mammal. The surface area of the “phagocytic epithelium” of the birds was very extensive. Compared with mammals, in general, FRMs are fewer in birds. Despite this, the pulmonary defensive status in birds may not necessarily be compromised: functionally, avian FRMs appear to be more efficient. Moreover, their defense function is complimented particularly by the phagocytic activity of the epithelium immediate to the blood-gas barrier, the most vulnerable site of the lung-air sac system. / WHSLYP2017

Em razão disso, o propósito deste trabalho é apresentar uma metodologia que possibilite a utilização dos fluorocromos como forma de análise do processo de reparo alveolar. Para tanto, 5 ratos tiveram o incisivo central superior direito extraído. Aos 6 dias foi injetada a calceína, aos 15 dias a alizarina e aos 21 dias a oxitetraciclina. Após 35 dias esses animais foram sacrificados. Obtidas as peças, foi analisado o terço médio do alvéolo. Observou-se predominância de calceína junto à parede lingual, grande quantidade de marcação com alizarina e a marcação da oxitetraciclina em menor quantidade, mostrando que houve menor taxa de mineralização óssea. Este trabalho foi capaz de mostrar a dinâmica do processo de reparo alveolar de forma clara e bastante ilustrativa, além de ser de fácil reprodução e apresentar um custo relativamente baixo. / Several methods have been employed in the study of the alveolar repair process. For this reason, the aim of this study is to present a methodology that allows the use of fluorochromes in the analysis of this process. Thus, 5 rats had their upper right central incisors extracted. At day 6 calcein was injected, at day 15 alizarin was injected, and at day 21, oxytetracycline was injected. After 35 days the animals were euthanized. After the samples were obtained, the middle third of the socket was analyzed. Predominance of calcein was observed next to the lingual wall. A great amount of alizarin staining and a smaller amount of oxytetracycline staining were also observed, showing that there was a smaller rate of bone mineralization. This study was able to show the dynamics of the socket repair process in a clear and illustrative manner, besides being easy to reproduce and relatively inexpensive.
