A perda embrionária consiste em perda econômica significativa dentro do processo de criação de equinos e representa custos adicionais para os criadores decorrentes das repetidas coberturas de éguas durante a temporada reprodutiva, além da diminuição do número de potros nascidos. São consideradas perdas embrionárias aquelas que ocorrem até o 49º dia da gestação e são decorrente de diversos fatores maternos e/ou embrionários. Atualmente, com a utilização da ultrassonografia, pode-se observar a vesícula embrionária a partir do 11º dia pós-ovulação, sendo possível o diagnóstico precoce de tais perdas. Devido ao grande prejuízo econômico na reprodução equina decorrente de perdas gestacionais, o objetivo deste Trabalho de Conclusão de Curso foi realizar revisão de literatura sobre as principais causas da perda embrionária em éguas

Following the guidelines of the United Nations, which established the Decade of Education for Sustainable Development (2005-2014) and the Principles for Responsible Management Education (PRME), the pressure on business schools for incorporating environmental management in their core activities (teaching, research, extension and university management) have intensified. In contrast, in Brazil, this discussion is still embryonic, and in some cases, the Business Schools seem to be in latter than the environmental management practiced by the world-class companies in the industrial sector. Therefore, this article prospected and systematized the state of the art on the inclusion of environmental management issues in the activities of Business Schools, by mapping the territory of the main academic works in this subject. The main results indicate that the state of the art is represented by: a vibrant leadership of U.S. researchers and others developed countries, a clear analytical reductionism of research, mainly by focusing on the dimension "teaching" does not addressing a systemic perspective that encompasses environmental management in the range of typical activities of Business Schools, a significant predominance of theoretical studies on the subject and a consequent lack of empirical studies, mainly based on multiple cases.

Sonohysterography was firstly described three decades ago. The saline solution infusion into the uterine cavity favors its use and provides excellent visualization of the anatomy and the inner cavity of the uterus better than the conventional transvaginal sonography To check the current role of sonohysterography in the uterine cavity assessment in women with abnormal uterine bleeding and asymptomatic, a literature review comparing sonohysterograph with conventional transvaginal sonography and/or ambulatory diagnostic hysteroscopy was carried out. To this end, relevant studies were researched in electronic databases Medline/PubMed, SciELO/LILACS. The sonohysterography is an ambulatory procedure, non-invasive, better cost-benefit, better sensitivity and specificity to identify uterine abnormalities, causing minimal discomfort and low complications rate. It was subject to revision which there is no more doubt about its accuracy. It can be concluded that the sonohysterography is a useful tool in the propedeutics to assess uterine cavity of symptomatic patients with abnormal uterine bleeding, infertility, recurrent miscarriages, and embryonic implantation failures in assisted reproduction treatment / in vitro fertilization and in any other intra and extra uterine cavity alteration. Hence, conventional transvaginal sonography is indicated as an initial method of assessment of the uterine cavity previously to ambulatory diagnostic hysteroscopy.

We investigated estradiol benzoate effects on oocytes/embryos recovery rate and the influence of this drug on the hematopoietic system. Twenty four bitches were divided in two groups, Group I, 12 females that received a single shot of estradiol benzoate, 0.2 mg/kg intramuscularly, between 2 and 7 days after the date of the last mismating or insemination and, Group II (control), 12 bitches that received 0.2 ml/kg of oily diluent, in corresponding dates. The bitches were ovary-hysterectomized and the uterus/oviduct were isolated and flushed with a PBS, heparin and polyvinyl alcohol solution. Oocytes and embryos were quantified and classified according to their stage of development. Blood counts were performed on M1 (before drug administration), M2 (15 days after drug administration) and M3 (40 days after drug administration). Pearson correlation coefficient was used to analyze the variable retrieval structures, while Fisher exact test was used for the analysis of embryonic viability. ANOVA was used to analyze repeated measurements and Tukey test for hematological parameters. All tests were performed at 5% significance level. The recovery rate of total structures in group I was lower (22.88%) than group II (65.85%). A lower embryo recovery (ratio 3: 52) rate and a greater number of degenerated structures (ratio 11: 1) were observed in group I. Hematological parameters showed significant difference in erythrocytes, hematocrit and hemoglobin concentrations 15 days after drug administration and difference in leukocytes concentration 40 days after using the medication in bitches of group I, however, at the end of the experiment all bitches had blood counts considered normal.
