A large number of edible seaweeds are consumed by the coastal peoples of Asia. Some of them are used in traditional remedies in many parts of the world. In this study we investigated effects of supplementation with ethyl acetate extracts of the brown alga Eisenia bicyclis (EBE) on rat macrophage to evaluate the possibilities as immune-modulators. Twelve male SD rats were divided into two groups and the treatments were as follows: A, no Eisenia bicyclis extract (EBE) intake and distilled water ; B, oral supplemented with EBE 200 mg/kg. After 5 weeks of supplementation, rats were sacrificed to assess the effect on peritoneal macrophage functions. We showed no increasing effects on tumoricidal activity, phagocytic activity and NO production in macrophages in EBE supplementation group. However, EBE supplementation suppressed NO-iNOS production and p65 translocation into the nucleus in LPS-stimulated macrophages. Overall, these results suggest that the supplementation of EBE might have an anti-inflammatory effects on NO-iNOS production in macrophages throughout the inhibition of NF-κB activation.
