ABSTRACT

Background:The use of meshes in hernia surgical repair promoted revolution in the surgical area; however, some difficulties had come, such as a large area of fibrosis, greater postoperative pain and risk of infection. The search for new substances that minimize these effects should be encouraged. Medicinal plants stand out due possible active ingredients that can act on these problems.Aim:To check the copaiba oil influence in the repair of abdominal defects in rats corrected with Vicryl(c) mesh. Method:Twenty-four Wistar rats were submitted to an abdominal defect and corrected with Vicryl(c) mesh. They were distributed into two groups: control and copaíba via gavage, administered for seven days after surgery. The analysis of the animals took place on 8, 15 and 22 postoperative days. It analyzed the amount of adhesions and microscopic analysis of the mesh.Results:There was no statistical difference regarding the amount of adhesions. All animals had signs of acute inflammation. In the control group, there were fewer macrophages in animals of the 8th compared to other days and greater amount of necrosis on day 8 than on day 22. In the copaiba group, the number of gigantocytes increased compared to the days analyzed.Conclusion:Copaiba oil showed an improvement in the inflammatory response accelerating its beginning; however, did not affect the amount of abdominal adhesions or collagen fibers.


Racional:A utilização de telas nas herniorrafias foi grande revolução na área cirúrgica; contudo, elas trouxeram algumas dificuldades, como grande área de fibrose, maior dor pós-operatória e risco de infecção. A busca por novas substâncias que minimizem esses efeitos deve ser estimulada. As plantas medicinais se destacam por apresentaram conjunto de princípios ativos que podem atuar em todos esses problemas.Objetivo:Verificar se o óleo de copaíba influência no reparo de defeitos abdominais em ratos corrigidos com tela de Vicryl®.Método:Vinte e quatro ratas Wistar foram submetidas a um defeito abdominal e corrigidos com tela de Vicryl®. Elas foram distribuídas em dois grupos: controle e copaíba via gavagem, administrada durante sete dias após a operação. A análise dos animais ocorreu nos dias 8, 15 e 22 de pós-operatório. Foi analisada a quantidade de aderências e feita análise microscópica da tela.Resultados:Não houve diferença estatística em relação à quantidade de aderências. Todos os animais tiveram sinais de inflamação aguda. No grupo controle, houve menor quantidade de macrófagos nos animais do dia 8 em relação aos demais dias e maior quantidade de necrose no dia 8 do que no dia 22. No grupo copaíba, o número de gigantócitos aumentou em relação aos dias analisados.Conclusão:O óleo de copaíba mostrou melhora na resposta inflamatória acelerando o seu início; contudo, não interferiu na quantidade de aderências abdominais ou fibras colágenas.

ABSTRACT

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. .

ABSTRACT

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.

ABSTRACT

Los quistes dentígeros son quistes odontogénicos que rodean la corona de un diente incluido o retenido, comúnmente asociados a terceros molares inferiores y que no se han diagnosticado a tiempo. Pueden alcanzar grandes tamaños, son los segundos quistes en orden de frecuencia, siendo el quiste radicular el primero. Se presenta el caso de una paciente de sexo femenino con un quiste dentígero gigante en maxilar inferior, el cual fue tratado con técnica de cicatrización por segunda intención, preconizada por Finochietto-Yoel, sin relleno óseo, ni placa de titanio, con una técnica de enucleación y curetaje conservadora, sólo con la utilización de gasa iodoformada embebida en una solución quirúrgica de 50 por ciento de eugenol, 25 por ciento de bálsamo de Perú y 25 por ciento de bálsamo de Canadá.

ABSTRACT

Purpose: To verify the copaiba balsam (Copaifera officinalis) effect on Walker 256 carcinoma inoculated into vagina and uterine cervix of rats. Methods: Eighteen female Wistar rats weighing between 180-250g were used, distributed into 2 groups (GCop, GC). On the 1st day of the experiment, 0.3 ml of Walker 256 carcinoma (2x10(6) concentration) was inoculated in both groups; on the 3rd day of the experiment, it was given 4.8 ml/kg of distilled water to the GC group, and 4.8 ml/kg of copaiba balsam to the GCop group. On the 12th day, euthanasia was performed and the tumor was grafted, being weighted and verified its volume. The data were submitted to statistical analysis with ANOVA test. Results: It was observed that copaiba balsam presented a negative inhibitory potential of 70 percent. Conclusion: The copaiba balsam stimulated the tumor growth.


Objetivo: Verificar o efeito do óleo de copaíba da espécie Copaifera officinalis no carcinoma de Walker 256 inoculado em vagina e colo de útero de ratas. Métodos: Foram utilizadas 18 ratas da linhagem Wistar, pesando entre 180-250g, distribuídas em dois grupos (CCop, GC). No 1º dia de experimento, em ambos os grupos foi inoculado 0,3ml de tumor de Walker 256 na concentração de 2x10(6); no 3º dia após essa inoculação, foi iniciada a administração de água destilada na dose de 4,8 ml/kg ao GC, e copaíba na dose de 4,8 ml/kg ao GCop. No 12º dia foi realizada a eutanásia das ratas e ressecado o tumor, sendo este pesado e averiguado seu volume. Os dados obtidos foram submetidos à análise estatística pelo método ANOVA. Resultados: Observou-se que o óleo de copaíba apresentou um potencial inibitório negativo de 70 por cento. Conclusão: O óleo de copaíba estimulou o crescimento tumoral.

ABSTRACT

Se estudia la efectividad del propoleo para irrigar zonas intervenidas quirurgicamente en pacientes con distintas afecciones bucales. En las ulceras bucales, la disminucion del dolor y la cicatrizacion fue mas rapida que en el grupo donde se aplico el balsamo de Chostakovski. Se concluye que las propiedades antimicrobianas, hemostaticas y antiinflamatorias del propoleo favorecieron una recuperacion mas rapida y mejor de los tejidos en el posoperatorio de los pacientes intervenidos quirurgicamente, que en aquellos del grupo control. Asimismo, se obtuvo una regresion mas rapida de los sintomas dolorosos y una mejor curacion de las ulceras al comparar los resultados en ambos grupos
