摘要
目的 探讨蛇纹石降氟前后砖茶水对小鼠骨髓嗜多染红细胞微核率的影响。方法 用活化的蛇纹石除去砖茶水 (氟浓度为 3 .0 mg/L)中的氟至 1.0 mg/L。将降氟前后的砖茶水各分高、中、低 3个剂量组进行灌胃 ,阴性对照组和阳性对照组分别用生理盐水灌胃和环磷酰胺腹腔注射。比较各实验组及阳性对照组与阴性对照组的微核率。结果 蛇纹石降氟前及降氟后各砖茶水组微核率与对照组相比差别均无显著性 (P >0 .0 5)。结论 无论降氟前降氟后 ,砖茶水都未引起小鼠骨髓嗜多染红细胞微核率升高 。
Objective To study the effects of brick tea l iquor before and after defluoridation by serpentine on micronucleus rate in mice .Methods The level of fluoride in brick tea liquor was reduced from 3.0 mg/L to 1.0 mg/L, then mice were injected according to low, middle and high fluoride dosage with brick tea liquor before and after defluori dation by serpentine, respectively. The micronucleus rates of polychromatic eryt hrocyte in mouse marrow of different groups were determined.Results The micronucleus rates of the brick tea liquor before and after defluoridation by serpentine were higher than those of control group. However, the difference was not significant (P>0.05).Conclusions The brick tea liquor before and after deflu oridation by serpentine cannot give rise to micronucleus rate of mice. So the b rick tea liquor before and after defluoridation by serpentine cannot bring obvio us damage to the chromosome of mice.
