Results of the lung micronucleus assay through ex vivo culture after whole-body inhalation exposure. Left (A) and right (B) panels show the results of the first and confirmatory tests, respectively. The Y-axis indicates the incidence of micronucleated (MN) cells. Each treatment group is shown under the bars. The data correspond to the mean ± SD. * p< 0.05 compared to the control (Fisher’s exact test).
