Can a simple test in bacteria identify cancer-causing chemicals in humans?
BJHS ThemesSince the 1950s, US officials have sought to reduce cancer incidence by regulating chemical exposures. However, rodent carcinogenicity tests are lengthy and expensive, making it impractical to identify carcinogens among the tens of thousands of chemicals

Zhongguo youzhi为评价樟树籽仁油的食用安全性，通过细菌回复突变试验、体外哺乳类细胞TK基因突变试验及哺乳动物红细胞微核试验探究樟树籽仁油的致突变和潜在致癌作用。结果表明：樟树籽仁油对组氨酸缺陷型鼠伤寒沙门氏菌TA1535、TA97、TA98、TA100、TA102均无致突变作用；樟树籽仁油未抑制L5178Y小鼠淋巴瘤细胞的生长，对体外哺乳类细胞TK基因无致突变作用；樟树籽仁油未导致小鼠细胞微核率上升，对哺乳动物红细胞无致突变作用，无遗传毒性。综上，樟树籽仁油无细胞致突变和潜在致癌作用，没有遗传毒性，具有一定的食用安全性。
