  • Antitumorigenic and antimutagenic activities of the doenjangs prepared from mushroom mycelia-cultured traditional mejus (designated to MTDJ) were investigated using the model of Sarcoma-180-induced mouse ascites cancer, and 2-amino-3-methylimidazo [4,5-f] quinoline (IQ) and aflatoxin B$_1$ (AFB$_1$) -mediated S. typhimurium mutagenicity, respectively. Antioxidative activity of MTDJ was also investigated using the mouse liver microsome system. Mushroom stains used for the preparation of the mushroom mycelia-cultured traditional mejus were Synryeong (Agaricus blazei), Yeonggi (Canoderma Iucidum), Sanghwang (Phellinus linteus), and Neutari (Pleurotus ostreatus). All MTDJS showed the enhanced antitumorigenicities (12% by Synryeong, 13% by Sanghwang, 16% by Yeonggi, and 19% by Neutari), antimutagenicity (6.1~20.8% for IQ and 3.1~10.2% for AFB$_1$), and antioxidative activity (6.6~46.5%), relative to the control doenjang. The $\beta$-D-glucan content (0.75~1.71 mg/g) of MTDJs was 3~8 times higher than that (0.22 mg/g) of the control doenjang. Genistein content (769~932 Ug/g) of MTDJS was also higher than that (728 Ug/g) of control doenjang The content of $\beta$-D-glucan and genistein was not exactly correlated to the antitumorigenicity and antimutagenicity of MTDJs. These results indicate that anti-tumorigenicity and antimutagenicity of MTDJS were elevated in comparison with the control doenjang, and the observed functions were, in part, derived from $\beta$-glucan and/or genistein in the MTDJS.
