Influence of oophorectomy on glycemia and lipidogram

Purpose: To verify the influence of oophorectomy on lipidogram and glycemia. Methods: Fifty six female rats were divided into the following 7 groups (n = 8): group 1 - sham group, group 2 - oophorectomy 30 days, group 3 - oophorectomy 35 days, group 4 - oophorectomy 40 days, group 5 - oophorectomy 45 days, group 6 - oophorectomy 70 days, group 7 - oophorectomy 55 days. Animals were following by number of days according the group. Was evaluated the serum levels of glucose and lipid profile. Results: The oophorectomized rats presented higher glycemia. Groups 3, 4, 6 and 7 had a higher glycemia and LDL levels (except for group 6) and groups 6 and 7 had lowest levels of HDL. Group 7 had highest level of VLDL than oophorectomy groups. There was no difference in triglycerides levels. Conclusion: Oophorectomy was related to dyslipidemia and insulin resistance, mainly after 50th days.(AU)

Publication rate of abstracts presented in a Brazilian experimental surgery congress

PURPOSE:To verify the publication rate of the abstracts presented at the XII Brazilian Congress of Experimental Surgery.METHODS:We performed a cross-sectional study that evaluated if the abstracts accepted for presentation at the XII Brazilian Congress of Experimental Surgery were published in periodics. The information was acquired using the Scielo, Medline / Pubmed, LILACS and Google Scholar databases.RESULTS:From all the abstracts presented, only 77 (40.52%) were published in scientific journals. Of this total, 14 (18.18%) were published prior to the conference 35 (45.45%) in the same year that occurred congress, 56 (72.72%) in the period 2011-2013 and 63 (81, 81%) between the Congress and the year 2015. Regarding the geographical distribution of summaries, 42 (22%) were from the northern region, 19 (10%) from the Northeast, 8 (4%) Midwest, 116 (61%) from the Southeast and 5 (3%) from the south.CONCLUSION:The publication rate of the abstracts presented at the XII Brazilian Congress of Experimental Surgery was 40,52%, most from the state of Sao Paulo.(AU)

Copaiba oil effect under different pathways in mice subjected to sepsis

PURPOSE: To evaluate the effects of copaiba oil administered by different routes on survival of mices subjected to cecal ligation and puncture. METHODS: Thirty two mice were distributed into four study groups (N=8): Sham group: normal standard animals; Control group: submitted a cecal ligation and puncture (CLP); Gavage group: submitted a CLP, and treat with copaiba oil by gavage; and Subcutaneous group: submitted a CLP, and treat with copaiba oil by subcutaneous injection. After the death of the histological analysis were performed. The Kaplan-Meier curves of surviving time were realized. RESULTS: All animals that received copaiba, regardless of the route used, survived longer when compared to the control group (p<0.0001), whereas the survival time ranged from 20 hours for the control group up to 32 hours for the animals of gavage group and 52 for subcutaneous group. The animals that received gavage copaiba lived about and about 20 hours unless the subcutaneous group (p=0.0042). There was no statistical difference when compared the intensity of inflammatory response (p>0.05) CONCLUSION: Prophylactic subcutaneous administration of copaiba in mice subjected to severe sepsis by cecal ligation and puncture, resulted in a survival time higher than non-use or use of this oil by gavage.(AU)

Immunohistochemistry of the uterine cervix of rats bearing the Walker 256 tumor treated with copaiba balsam

PURPOSE: To investigate the immunohistochemistry of the uterine cervix of 20 Wistar rats (Rattus norvegicus) bearing the Walker 256 tumor, treated with copaiba oil (Copaifera officinalis). METHODS: The animals were grouped into four subgroups, with five rats each: the GCT and GCopT received distilled water and topically copaiba, respectively, while the GCG and GCopG received distilled water and copaiba by gavage, respectively. The substances were administered for nine days. On the 12th day, after euthanasia, the tumor pieces were sent to the identification of T CD4+, T CD8+ and Natural Killer cells. RESULTS: It was found that the pattern of expression for specific markers of phenotypes of cells involved in tumor immune response was similar in all groups, regardless the administration way of copaiba oil (topical or gavage). CONCLUSION: Copaiba balsam, administered either topically or by gavage, did not alter the pattern of tumor immune response in rats bearing Walker 256 Tumor.(AU)

Evaluation of the key words used in articles of the Acta Cirurgica Brasileira from 1997 to 2012 / Avaliação dos descritores utilizados nos artigos da Acta Cirúrgica Brasileira de 1997 a 2012

PURPOSE: To evaluate the key words used in Acta Cirurgica Brasileira from 1997 to 2012. METHODS: All the key words of all articles published in regular issues between 1997 and 2012 were analyzed, ensuring that these key words were in the MeSH database (Medical Subjects Headings) and the most used subject headings and most wrong repeated key words were ranked. RESULTS: > 4230 key words used in 990 articles were analyzed. Only 579 key words (13.68%) were not in the MeSH database, considering that there was a statistically significant decrease over the years (p<0.001). The three most used key words were Rats, Dogs and Wound healing. Among the wrong ones, the key words were Adhesions, Experimental surgery and Anatomosis. CONCLUSION: There was a gradual improvement in the amount of key words used that belonged to the MeSH database, and there were 618 articles (62.42%) with all key words correct.(AU)

OBJETIVO: Avaliar os descritores utilizados na Acta Cirúrgica Brasileira entre os anos de 1997 até 2012. MÉTODOS: Foram analisados os descritores de todos os artigos publicados em fascículos regulares entre os anos de 1997 a 2012, verificando se estes constavam no MeSH e foi feito um ranking dos descritores mais utilizados e dos termos equivocados mais repetidos. RESULTADOS: Foram analisados 4230 descritores, presentes em 990 artigos. Apenas 579 (13,68%) dos descritores estavam fora da base do MeSH, sendo que houve uma diminuição estatisticamente significante com o passar dos anos (p<0.001). Os três descritores mais utilizados foram Rats, Dogs e Wound healing, já dentre as equivocadas foram os termos Adhesions, Experimental surgery e Anatomosis. CONCLUSÃO: Houve uma melhora progressiva na quantidade de termos utilizados que pertenciam a base do MeSH, havendo 618 artigos (62,42%) com todos os descritores corretos.(AU)
