Twenty-four bitches which had been in labour for less than 12 hours were randomly divided into four groups of six. They all received 0(.)5 mg/kg of chlorpromazine intravenously as premedication, followed 15 minutes later by either 8 mg/kg of thiopentone intravenously (group 1), 2 mg/kg of ketamine and 0-5 mg/kg of midazolam intravenously (group 2), 5 mg/kg of propofol intravenously (group 3), or 2(.)5 mg/kg of 2 per cent lidocaine with adrenaline and 0(.)625 mg/kg of 0(.)5 per cent bupivacaine with adrenaline epidurally (group 4). Except for group 4, the bitches were intubated and anaesthesia was maintained with enflurane. The puppies' heart and respiratory rates and their pain, sucking, anogenital, magnum and flexion reflexes were measured as they were removed from the uterus. The puppies' respiratory rate was higher after epidural anaesthesia. in general the puppies' neurological reflexes were most depressed after midazolam/ketamine, followed by thiopentone, propofol and epidural anaesthesia.

The aim of this study was to investigate the use of ropivacaine combined or not with different opioids, for epidural anesthesia in bitches submitted to elective ovariosalpingohisterectomy (OSH). Thirty two mixed-breed female dogs, adults were used with medium weigh of 10.5kg. The animals were premedicated with acepromazine (0.05mg.kg-1, IM) and midazolam (0.2mg.kg-1, IM) and allocated in four experimental groups: group 1(n=8): ropivacaine: 0.3 mL.kg-1; group 2(n=8): ropivacaine + morphine (0.1 mg.kg-1); group 3(n=8): ropivacaine + butorphanol (0.1 mg.kg-1); and group 4(n=8): ropivacaine + tramadol (0.5 mg.kg-1) administered epidurally. Heart and respiratory rate; systolic arterial pressure; rectal temperature; arterial blood gas partial pressures; blood pH; sedation and muscular relaxation degree were evaluated at different experimental moments. The data were submitted to ANOVA and compared by Kruskal Wallis, Friedman, Dunn, Tukey and Chi-square test (p≤0.05). Minimum cardiorespiratory alterations were observed and the group of the ropivacaíne combined with the butorphanol (G3) presented a more cranial blockage, what allowed the accomplishment of OSH without induction in six animals (75%) whereas most of the others needed anesthetic rescue. The results allow us to conclude that the use of ropivacaine sole or combinated with morphine, butorphanol or tramadol, for epidural anesthesia, didn't promote significant cardiorrespiratory depression and the ropivacaine associated to the butorphanol allowed the accomplishment of OSH in bitches.

This article analyzes how the Brazilian feminist movements utilize online social networks to expand their sphere of action and mobilization in society through understanding how is the activity of the collective Marcha das Vadias of Rio de Janeiro on your Facebook page and as this group is mobilized in the online environment to organize its annual march, here, specifically the 4th Marcha das Vadias of Rio de Janeiro. Through exploratory, descriptive and analytical qualitative research methodology and analysis of social networks on the Internet, it is concluded that the network generated by the topic "4th Marcha das Vadias of Rio de Janeiro" was central dynamic between a public clear feminist, but weak and little to comprehensive dialogue with society in general positions.

A contracepção cirúrgica é utilizada no controle populacional, por impedir definitivamente a reprodução e ser mais econômica em relação à eutanásia. As complicações ocorrem pela intervenção cirúrgica ou por efeitos sistêmicos da privação do estrógeno. Objetivou-se monitorar o período pós-operatório de cadelas e gatas castradas em projeto de extensão universitária, com o intuito de avaliar os benefícios e a incidência de efeitos adversos. Foram questionados por telefone os proprietários de 178 fêmeas castradas (135 caninas e 43 felinas), entre um e dois anos após a cirurgia. As questões envolviam o estado atual do animal, possível mortalidade, neste caso a causa da morte e quanto tempo após a cirurgia ocorreu, se ocorreram alterações físicas como ganho de peso, incontinência urinária e dermatite peri-vulvar e alterações comportamentais positivas, como docilidade e diminuição do comportamento de perambulação, ou negativas, como apatia, agressividade e agitação excessiva. Das 135 cadelas castradas, 12 (8,89%) apresentaram óbito, apenas um relacionado à cirurgia, 87 (64,44%) apresentaram ganho de peso após a cirurgia, uma (0,74%) apresentou incontinência urinária e quatro (2,96%) dermatite peri-vulvar. Alterações de comportamento positivas foram relatadas em 38 (28,15%) cadelas e negativas em seis (4,44%). Das 43 gatas castradas, seis (13,95%) apresentaram óbito, nenhum relacionado à cirurgia, 25 (58,14%) apresentaram ganho de peso, uma (2,32%) incontinência urinária e duas (4,65%) dermatite peri-vulvar . Alterações de comportamento positivas ocorreram em 20 fêmeas (46,51%) e alterações negativas em nenhuma fêmea (0%). Pode-se concluir que a contracepção cirúrgica apresenta boa relação custo-benefício no que diz respeito a alterações pós-operatórias de longo prazo.

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.
