Abstract

Aim: Swelling of the tumor in the liver is difficult to stop by ordinary medicine. Then, new
and safe drug preventing tumor-growth is required.
Method: Three Sprague-Dawley rats, injected chemical carcinogen of diethyl- nitrosamine for
12 weeks, are then fed the edible brown-alga Kinu-Mozuku, grown at seashores around Noto
peninsula, Japan, for 3 weeks.
Results: No liver tumor is found in three Kinu-Mozuku-fed sample rat. On the contrary, all
the three control-rats, fed without Mozuku, show very large tumor in their livers. This
observation is statistically significant (P = 0.05 by Mann-Whitney’s U test).   Conclusion: Japanese edible Kinu-Mozuku (Nemacystis decipiens) is proven to be the strong
foodstuff/drug preventing enlargement of liver-tumor in the outbred rat. Thus, the edible
fucoidan is expected to be the powerful and safe drug/medicine preventing and healing the
human HCC and also the other intractable human cancers.
