Anti Cancer Effects Of Spirulina

Inhibition of experimental oral carcinogenesis by topical beta carotene. by Schwartz, et al. 1986. Harvard School of Dental Medicine. Pub. in Carcinogenesis, May 1986 7(5) 711-715. USA. Beta carotene was found to significantly inhibit the formation of squamous cell carcinoma of hamster buccal pouch when a solution was applied topically three times weekly for 22 weeks in an experiment with 40 hamsters. In a second experiment with 80 hamsters, beta carotene was found to inhibit oral carcinogenesis in an initiation-promotion hamster buccal pouch system. Beta carotene in hibited both initation and promotion. Prevention of experimental oral cancer by extracts of spirulinadunaliella algae. by J. Schwartz, G. Shklar, et al. 1988. Harvard School of Dental Medicine. Pub. in Nutrition and Cancer 11, 127-134. 1988. USA. An extract of Spirulina-Dunaliella algae was shown to prevent tumor development in hamster buccal pouch when a solution was applied topically three times weekly for 28 weeks. Untreated control animals all presented gross tumours of the right buccal pouch. Animals fed canthaxanthin presented a notably and statistically significant reduction in tumour number and size compared with controls. Animals fed beta carotene demonstrated a smaller but statistically significant reduction in tumor number and size. The algae animals presented a complete absence of gross tumors. However, microscopic sections of the buccal pouch in the algae group showed localized areas of dysplasia and early carcinoma-in-situ undergoing destruction.
