Bovine placentome preservation for light microscopy evaluation

This work evaluates the preservation of bovine placentomes using paraformaldehyde and glutaraldehyde at 4% and solutions of Karnovsky, Bouin and Carnoy for 4, 12 and 24 hours fixation, at room temperature or at 4ºC, before inclusion in plastic resin and paraffin. The best preservation of the specime...

description This work evaluates the preservation of bovine placentomes using paraformaldehyde and glutaraldehyde at 4% and solutions of Karnovsky, Bouin and Carnoy for 4, 12 and 24 hours fixation, at room temperature or at 4ºC, before inclusion in plastic resin and paraffin. The best preservation of the specimens was obtained after 12 hours of fixation with those solutions containing aldehydes. With Bouin solution the best time of fixation was 4 hours, while for Carnoy solution the best time of fixation was 24 hours. Inclusion in plastic resin gave better results than in paraffin, and the temperature did not influence the quality of preservation of the specimens of bovine placentomes for evaluation with light microscopy. Avaliou-se a preservação de placentomas bovinos com as soluções fixadoras paraformaldeído e glutaraldeído a 4% e soluções de Karnovsky, Bouin e Carnoy nos tempos de 4, 12 e 24 horas de fixação, à temperatura ambiente ou a 4ºC, incluídos em resina plástica e parafina. A melhor preservação dos placentomas foi obtida com os fixadores à base de aldeídos, a partir de 12 horas de fixação. Em Bouin, os espécimes foram melhor preservados quando fixados por 4 horas, enquanto que em Carnoy a preservação foi melhor com 24 horas. A inclusão em resina plástica apresentou resultados superiores do que em parafina. A temperatura de fixação, 4ºC ou ambiente, não influenciou na preservação dos espécimes de placentoma para estudos em microscopia óptica.
