The immune stimulating activities of polysaccharides from five micro-algae toward mice cells ，including stimulating spleen lymphocyte proliferation and macrophage proliferation, enhancing phagocytic activity of neutral red, increasing nitro oxide (NO) production were tested. The results showed that the polysaccharides from these five micro-algae had stimulating activities on cells mediated immunity in mice. The Porphyridium creuntum polysaccharides had the effect of enhancing phagocytic activity of neutral red, increasing nitro oxide (NO) production, and stimulating spleen lymphocyte proliferation and macrophage proliferation. It proved that Porphyridium creuntum polysacchari
