Are there thresholds for carcinogens carcinogenicity?
魚や肉などの焼けこげに含まれている2-amino-3,8-dimethylimidazo[4,5-f ] quinoxaline(MeIQx)のラット肝臓における低用量発がん性を中期発がん性試験法で検討した.その結果,MeIQx?DNA 付加体形成は微量からみられ,より高い用量で8-hydroxy-2′-deoxyquanosine 形成,lacI 遺伝子変異,イニシエーション活性等が誘発された.また,肝臓の前腫瘍性病変であるglutahione S-transferase placental(GST-P)陽性細胞巣は,さらにより高い用量で誘発された.N- ニトロソ化合物であるN-nitrosodiethylamine やN-nitrosodimethylamine でもGST-P ...
