| 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. |

| Morphological changes in the placenta at periparturition and the involvement of apoptosis controlling cell populations in the placentome were evaluated in Holstein and Nelore cows. Twenty-two Holstein cows at the end of gestation with normal non-induced parturition (group I) and 10 Holstein cows with induced parturition (group II) were used in this study. In addition, groups III and IV were constituted by 10 Nelore cows at the end of gestation with normal non-induced parturition and 21 Nelore cows with induced parturition, respectivelly. Binucleate trophoblastic cells, epithelial caruncular cells and apoptotic bodies were quantified by light microscopy. Apoptosis was further evaluated by transmission electron microscopy, ELISA and DNA electrophoresis in... |
