PETALUMA, Calif., Feb. 20 /PRNewswire/ -- Scientists at the Osaka Institute of Public Health in Japan have found that Spirulina promoted the activation of natural cancer-fighting substances in the body. The study was reported at the 30th Annual Meeting of the Japanese Society for Immunology held in November 2000. In this clinical study volunteers over 40 years of age were given 50 ml of Lina Green 21 (a Spirulina extract) and the level of natural cancer-fighting substances were measured in their blood. The results showed that Spirulina significantly increased the tumor killing ability of Natural Killer Cells and interferon gamma. The interferon gamma and natural killer cell activity was increased 1-2 weeks after administration of Spirulina and the activity continued for a surprising 12-24 weeks even after stopping the administration of Spirulina. "These findings lend further support to the strong immune boosting activity of Spirulina found in many other similar studies including those by researchers at University of California, Davis and North Carolina State University," says Dr. Amha Belay, Senior Vice President of Earthrise Nutritionals. "Collectively these studies point to the potential of Spirulina for use in immunotherapy." In an earlier study reported at the 59th Annual Meeting of the Japanese Cancer Association (October, 2000) the Osaka group also found that the co-administration of Spirulina extract with a bacterial cell wall product significantly increased the regression of implanted tumor cells in mice compared to the administration of BCG-CWS alone. More than 80% remission was obtained with this co-treatment. "Both types of cells might have played complementary role to control cancer effectively," says Dr. Seya, the chief investigator of the study. According to the researchers this new treatment approach holds great promise. A cell wall material called BCG-CWS, derived from certain bacteria, has been commonly used in patients with lung cancer surgery. The administration of BCG-CWS resulted in the activation of one type of cancer-fighting substance called cytotoxic T-cells (CTL), which showed a moderate success. The co-administration of Spirulina extract with BCG-CWS increased the activation of other types of natural cancer-fighting substances called natural killer cells that work in concert with CTL's to give an enhanced effect.
