ABSTRACT
Many reports have indicated that differences in blood cells formation and function in fish could be of dietary origino Essential fatty acids are certainly connected with these cells by virtue of being a source of important compounds like eicosanoids, platelet activating factor in mammals, as well as the cell membrane phospholipids. The thrombocytes from fish fed the commercial diet containing adequate amount of essential fatty acids exhibited greater capacity for aggregation when induced by Collagen Type I(56%), however, this capacity was reduced when fish were fed the essential fatty acids deficient diet (37%). The results obtained in this study demonstrated that EFA exert influence in thrombocytes by affecting their aggregation capacity.
RESUMO
Indicações sobre alterações na formação das células sanguíneas e em suas funções nos peixes têm sido relatadas em diversos trabalhos. Os ácidos graxos essenciais (EFA) certamente estão ligados a essas células devido ao fato de constituírem fonte de componentes importantes, como os eicosanoides, fatores de ativação de plaquetas nos mamíferos, bem como de fosfolipídios de membrana. Trombócitos oriundos de peixes alimentados com uma dieta comercial contendo quantidades adequadas de EFA mostraram uma grande capacidade de agregação quando induzidos por colágeno do tipo I (56%), contudo, essa capacidade encontrou-se reduzida quando os peixes foram alimentados com uma dieta deficiente em EFA (37%). Os resultados obtidos nesse estudo demonstraram que os ácidos graxos essenciais exercem influência nos trombócitos afetando sua capacidade de agregação.
