Mitotic Epithelial Of The Lens Of Rainbow Trout Exposed To Benzene Compounds

Table 3: Changes in the mitotic index and frequency of occurrence of micronuclei in the lens epithelium of rainbow trout under the influence of various concentrations of nitrobenzene on 21 days of the experiment (data in%). Bold text indicates the results that have a significant difference in the mean values compared to the Student's criterion and y control (P<0.01)
