摘　　要：用不同浓度的漱口水溶液分别处理大蒜根尖8、12和24h,利用微核技术,研究漱口水对大蒜根尖细胞遗传损伤作用。结果表明,与对照组相比,漱口水处理组细胞微核率增加(P<0.05),分裂细胞数减少,分裂指数下降(P<0.05),表明漱口水对大蒜根尖细胞有遗传损伤作用。The research aimed to study the effect of mouthwash on the genetic damage of root tip cells of garlic, different concentrations of mouthwash were used separately to treat the root tip of garlic for 8, 12 and 24 h. The results showed that mouthwash induced the aberration of chromosomal and nuclear, the higher concentrations of mouthwash induced higher frequency of micronucleus rates(P<0.05). while he number of mitosis cell of divisions and mitotic index decreased(P<0.05), which were negatively correlated with the treatment time and dose of mouthwash. These results suggested mouthwash caused the genetic damage.
