| This study aimed to investigate the incidence of the influenza virus, and its interspecies transmission cycle among horses. A comparative serological survey was performed using horse sera following challenge with both specific (equine) and non-specific (human) influenza virus strains. Bleedings of the 22 horses were performed during the years 1999 and 2000. Following treatment with kaolin (20%), added in rooster erythrocytes suspension (50%), for removal of non-specific antibodies, sera were titered against both Human and Equine Influenza virus, by the Hemagglutination Inhibition Assay(HI), recommended by WHO. The HI results of horse serological responses demonstrate cross reaction between both the specific strain, A/Eq1 (H7N7) ( 62.75%) and A/Eq2 (H3N8)... |

| Birds are the most important reservoirs of the influenza virus. Its maintenance in its natural hosts, including man, allows the influenza virus to reassorts its strains. The recent report of an avian influenza A (H5N1) virus in humans, was in a child with fatal respiratory illness in China, 1997. The current study was conducted to elucidate the transportation of the influenza by birds that migrate, annually, through the both Northern and Southern hemispheres, with special attention paid to the Vireo olivaceus [Juruviara(BR) or Red-eyed vireo(USA)] species, which travels from the USA to Brazil, and vice versa, and the Elaenia mesoleuca [Tuque(BR) or (USA)] species that flies over the entire Southern Hemisphere. There are two species of birds, which breed... |

| A absorção dos compostos antioxidantes presentes no extrato hidroalcoólico da polpa da romã (Punica granatum, L.) foi avaliada utilizando-se o modelo de cultura de células, cuja linhagem escolhida foi a Caco-2, provenientes de um adenocarcinoma do cólon. O extrato hidroalcoólico da polpa apresentou um conteúdo de 832 µg equivalente de ácido gálico.mL-1 de extrato e sua atividade antioxidante mostrou valores de 5,9% (0,1 ppm) a 93,09% (8 ppm) de capacidade de redução do radical DPPH•. As células tratadas com o extrato apresentaram uma inibição de crescimento celular de 4,16% (200 ppm), e a absorção dos compostos antioxidantes foi de 63,25%. Para o ácido gálico, os resultados mostraram uma inibição de 2,98% (400 ppm) e uma absorção de 72,54% dos compostos... |
