MAGARA, J., HAGA, M., CHEN, W., ENDOH, K., YAMAMOTO, M., TSUTSUI, M., KATO, K. and AKAI, S. Rec-Assay of Human Bile for Mutagenicity and Co- Mutagenicity. Tohoku J. Exp. Med., 1989, 157 (2), 177-182-Spore rec-assay of human bile was conducted by the Bacillus subtilis test system to examine possible mutagenicity and co-mutagenicity. Of 26 samples examined, 8 (30.8%) showed mutagenic activity and 23 (88.5%) enhanced the mutagenic activity of mitomycin C.
