| The localization of peroxidase activity in different cell regions is used as a criterion for the classification of the stage of maturation of mammalian mononuclear phagocytes with a positive peroxidase reaction indicating the presence of monoblasts, promonocytes, monocytes and macrophages. In this study it was evaluated the peroxidase activity of blood mononuclear phagocytes of this turtle detected at different stages of differentiation. The present observations suggest that, in turtles, the differentiation of mononuclear phagocytes occur in the blood circulation, in contrast to animals, where only are monocytes in circulating blood and macrophage differentiation occurs in other body compartments |

| The aim of this article is to present the decalcification process dynamic of mineralized tissue in dogs, teeth and jaw, comparing the traditional decalcification method, immersion, and microwave, immersion followed by irradiation using a domestic microwave oven, accompanying the liberation of calcium through spectrophotometer of atomic absorption. It was used as decalcified agent, EDTA solution or nitric acid. The results showed that with the use of nitric acid (5%), after 15 days, the irradiated fragments could be processed for histological analysis, otherwise the tooth not irradiated need to be submerged for 65 days. The EDTA decalcified action was slower than the nitric acid. The histological observations of the irradiated samples showed an excellent... |
