Macroporous latex biomembrane from Hancornia speciosa modulates the inflammatory process and has a debridement effect on wound healing in rats.

PURPOSE: The angiogenic, osteogenic and anti-inflammatory activity of latex of Hancornia speciosa has been evidenced and indicates pharmacological potential with great applicability in the health area, especially in the wound healing process. The present work aimed to compare the effects of the H. speciosa macroporous latex biomembrane with saline on wound healing. METHODS: Forty-three Wistar rats were submitted to excisional wound induction procedure and divided into groups according to treatment: saline (G1), and macroporous biomembrane (G2). The animals were euthanized at three, seven, 14, and 21 days after injury induction (DAI), and three animals were used for the debridement test. Morphometric, macroscopic, and microscopic analyses of general pathological processes were performed. RESULTS: The macroporous biomembrane minimized necrosis and inflammation during the inflammatory and proliferative phases of the healing process, confirmed by the lower intensity of the crust and the debridement effect. In addition, the wounds treated with the macroporous biomembrane presented greater contraction rates in all the experimental periods analyzed. CONCLUSIONS: The macroporous biomembrane presents angiogenic, anti-inflammatory and debridement effects, contributing to the healing process, and can be considered a potentially promising new biomaterial to be used as a dressing.

Avaliação dos métodos de controle interno da qualidade no Laboratório Clínico da Pontifícia Universidade Católica de Goiás / Alternative method evaluation of internal quality control in the Clinical Laboratory of Pontifical Catholic University of Goiás

Objetivo: Analisar a confiabilidade e a eficácia dos métodos alternativos de controle interno de qualidade utilizados no Laboratório Clínico da PUC Goiás, entre setembro de 2016 a janeiro de 2017. Métodos: Foi realizada a avaliação dos métodos de dupla leitura através da estatística de Kappa, tabela de Rümke e teste T de Student, nas seções de parasitologia, hematologia e uranálise respectivamente. Para análise interlaboratorial se utilizou o teste de tipagem sanguínea e fator Rh. Avaliou-se ainda a eficácia do Algoritmo de Bull na seção de hematologia. Resultados: Na seção de parasitologia foi obtido um grau bom de concordância (0,79) entre ambos os leitores, já na hematologia foi encontrado um percentual de conformidade de (99,88%), enquanto que na uranálise a contagem de hemácias apresentou variância de (0,20578), leucócitos (0,92104), células epiteliais (0,85467), não caracterizando diferença significativa (p> 0,05). Durante a avaliação do Algoritmo de Bull foi detectada, em dois dias, valores que ultrapassaram o limite superior de erro (χ ± 2dp) em relação ao parâmetro número de eritrócitos (RBC). Não foi observada discordância na avaliação de processos interlaboratoriais. Conclusão: A análise dos resultados revelou que os métodos alternativos avaliados apresentaram alto índice de confiabilidade, podendo ser utilizados na rotina laboratorial como auxílio na qualidade do processo analítico.
