摘    要:目的: 研究2,4-二氯苯氧乙酸(2,4-D)是否具有潜在的遗传毒性。方法:利用Ames试验、小鼠骨髓嗜多染红细胞微核试验、小鼠睾丸初级精母细胞染色体畸变试验对2,4-D原药的致突变性进行研究。结果:与对照组比较,2,4-D原药各剂量组对TA97、TA98、TA100和TA102菌株均无诱发回复突变菌落数增加的作用(P>0.05),对小鼠骨髓嗜多染红细胞的微核细胞率亦无明显影响(P>0.05),也未引起小鼠睾丸初级精母细胞染色体畸变率明显改变(P>0.05)。结论:在本实验条件下,未发现2,4-D原药的致突变性。

Abstract:OBJECTIVE: To explore the potential mutagenicity of 2,4-dichlorophenoxyacetic acid. METHODS:Ames test,mouse bone marrow micronucleus test and mouse primary spermatocyte chromosome aberration test were conducted. RESULTS:Ames test showed no two-fold increase in the spontaneous reversion colonies compared with the negative control group (P〉0.05). No significant difference was found in chromosome aberration and micronucleus rate between control and experimental groups (P〉0.05). CONCLUSION:2,4-dichlorophenoxyacetic acid showed no mutagenicity under these test conditions.
Keywords:2  4-dichlorophenoxyacetic acid  Ames test  chromosome aberration  micronucleus  mutagenesis
