摘要
分别在d1、d3、d7、d14,观察空白对照(CK-)、水溶助剂0.1mL/L二甲基亚砜对照(CK+)、阿特拉津0.01mg/L(ρ1)、0.1mg/L(ρ2)、1mg/L(ρ3)和10mg/L(ρ4)溶液中弹琴蛙(Ranaadenopleura)蝌蚪血红细胞微核和核异常细胞数.结果表明,d14时,ρ1、ρ2、ρ3和ρ4组蝌蚪的微核率分别是CK-的2.25、2.50、4.25、5.11倍(P<0.05),说明阿特拉津可引起蝌蚪血红细胞微核率升高;且与d1、d3、d7相比较,微核率随着时间的延长有升高的趋势.d14时,ρ2、ρ3和ρ4组蝌蚪的总核异常率(含微核率)分别是CK-的2.59、2.17、1.96倍(P<0.05),说明阿特拉津也可引起蝌蚪血红细胞总核异常率升高.
Micronucleus and nucleus anomalies of erythrocytes of Rana adenopleura tadpoles were detected and observed in control (CK-), DMSO cosolvent (CK+), atrazine 0.01 mg/L (ρ1), 0.1 mg/L (ρ2), 1 mg/L (ρ3) and 10 mg/L (ρ4) after d 1, d 3, d 7 and d 14. The result indicated that the micronucleus frequencies of R. adenopleura tadpoles in ρ1,ρ2,ρ3 and ρ4 were 2.25, 2.50, 4.25 and 5.11 times higher than CK- (P<0.05). It was proved that atrazine could increase the frequency of micronucleus. Also, the frequency of erythrocytes nucleus anomalies of the tadpoles in ρ2,ρ3 and ρ4 were 2.59, 2.17 and 1.96 times higher than CK- after 14 d (P<0.05), and atrazine could increase the frequency of nucleus anomalies. The increment of micronucleus frequency depended on atrazine concentration. Fig 2, Tab 1, Ref 17
