ABSTRACT

PURPOSE: To evaluate surfactant protein A levels in an hepatopulmonary syndrome rat model. To date, there have been no studies aimed at evaluating surfactant levels in the setting of cirrhosis or hepatopulmonary syndrome. METHODS: A total of 35 rats were divided into control, sham, and experimental HPS groups. We evaluated surfactant protein A levels in rats and the experimental model designed to induce hepatopulmonary syndrome was common bile duct ligation. Statistical analysis was performed using GraphPad Prism Software(r). Differences were considered statistically significant when p<0.05. RESULTS: Lung homogenate of surfactant protein A levels were lower in the experimental hepatopulmonary syndrome and sham groups in comparison to the control group (p<0.05). Serum SP-A levels were the same in experimental hepatopulmonary syndrome and control groups but decreased in the sham group compared with the experimental groups (p<0.05). Myeloperoxidase activity was higher in the experimental hepatopulmonary syndrome group than the other two groups (p<0.05). CONCLUSION: Surfactant protein A is present in experimental hepatopulmonary syndrome and leads to an imbalance between serum and pulmonary levels due to systemic inflammatory response. .

ABSTRACT

A suscetibilidade da linhagem de células Vero ao vírus do sarampo é bem conhecida e sua utilizaçäo no controle da potência da vacina contra o sarampo é amplamente difundida. Com o objetivo de comparar a suscetibilidade de células Vero empregadas em titulaçöes, amostras provenientes de dois laboratórios controladores (Vero IB e Vero INCQS), foram testadas frente a três cepas vacinais: Moraten Schwarz e Biken CAM-70. Foram titulados 72 lotes de vacinas contra o sarampo, sendo 25 produzidos com a cepa Moraten, 24 com a cepa Schwarz e 23 com a cepa Biken CAM-70. A análise estatística dos resultados obtidos nas titulaçöes, feita através dos testes Limites para uma Média e "t" de Student, mostrou que para as cepas Moraten e Biken CAM-70, as diferenças de títulos näo foram estatisticamente significantes, o mesmo näo ocorrendo com a cepa Schwarz, para a qual as células Vero IB se mostraram mais sensíveis
