微核试验(Micronucleus Test MT)不仅作为染色体损伤的短期突变性测试方法,且在一定程度上反映了细胞核膜受损程度,在医源性致癌药理研究中是评定药物毒性的重要方法之一。近年来已被国际环境致突物致癌物防护委员会所肯定。美国食品安全委员会已正式采纳MT作为建议系统的测试项目之一,并规定MT一项为阳性时,就可以进行危险性的评价。本文试通过MT对我所近年来培植成功的人工虫草菌丝体及 Micronucleus Test MT not only serves as a short-term mutated test method for chromosome damage, but also reflects the degree of nuclear membrane damage to a certain extent. It is one of the important methods for assessing drug toxicity in iatrogenic carcinogenic pharmacology studies. In recent years, it has been affirmed by the International Committee for the Protection of Carcinogens from the Environmental Trap. The U.S. Food Safety Commission has formally adopted MT as one of the test items for the proposed system and stipulates that a risk assessment can be performed when MT is positive. This article tried to use MT to artificially cultivate Cordyceps mycelium that has been successfully cultivated in recent years.
