Item Acesso aberto (Open Access) Immunohistochemistry of the uterine cervix of rats bearing the Walker 256 tumor treated with copaiba balsam(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2013-03) BOTELHO, Nara Macedo; CORRÊA, Suelen Costa; LOBATO, Rodolfo Costa; TEIXEIRA, Renan Kleber Costa; QUARESMA, Juarez Antônio SimõesPURPOSE: 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.Item Acesso aberto (Open Access) Influence of tramadol on functional recovery of acute spinal cord injury in rats(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2018-12) CHAVES, Rosa Helena de Figueiredo; SOUZA, Celice Cordeiro de; FURLANETO, Ismari Perini; TEIXEIRA, Renan Kleber Costa; OLIVEIRA, Carolina Pinheiro de; RODRIGUES, Emanuelle de Matos; SANTOS, Daniel Arthur Santos dos; SILVA, Renata Cunha; PENHA, Nelson Elias Abrahão da; LIMA, Ana Rita dePurpose: To evaluate the influence tramadol on functional recovery of acute spinal cord injury in rats. Methods: Ten rats were divided into two groups (n = 5). All animals were submitted by a aminectomy and spinal cord injury at eighth thoracic vertebra. In control group, the rats didn’t receive any analgesic. In tramadol group, the rats received tramadol 4mg/Kg at 12/12h until 5 days by subcutaneous. Animals were following by fourteen days. Was evaluated the Basso, Beattie, Bresnahan scale (locomotor evaluation) and Rat Grimace Scale (pain evaluation) at four periods. Results: There no difference between the groups in locomotor evaluation in all periods evaluated (p>0.05) and in both groups there was a partial recover of function. The tramadol group show a lower pain levels at the first, third and seventh postoperatively days when comparing to the control group. Conclusion: The tramadol as an analgesic agent don’t influence on functional recovery of acute spinal cord injury in rats.
