| Research Abstract |
For purposes of proposing the therapeutic strategy for prevention of carcinogenesis, we did the study using saturated molecular hydrogen water, the selective scavenger of hydroxy radical species. In this study, we used Long-Evans Cinnamon (LEC) rats that are the model animals of human copper metabolic disease, Wilson disease. Until six month old, many of them have an attack of acute hepatitis caused by hydroxy radial species, and 20-30 % of male LEC rats die. It was reported that the almost survivals get liver cancers until a half and one year old. We administered saturated molecular hydrogen water or de-hydrogen water to LEC rats and Long-Evans Agouti (LEA) rats as negative controls. We made de-hydrogen water by degassing molecular hydrogen water. In the preliminary experiment, we found that liver carcinogenesis was prevented in the LEC rat drinking saturated molecular hydrogen water every day, although the LEC rat drinking de-hydrogen water had many tumors in the liver.
