From: Structural chromosome aberrations cause swelling of the nucleus
Non-mutagens induced nuclear swelling in L5178Y cells. NS = nuclear swelling (relative frequency of classes with swelling areas), RICC = relative increase in cell counts. (−S9) = without metabolic activation, (+S9) = with metabolic activation. The label values in the graph are the observed number of cells. Asterisks (*) indicate significant differences compared to controls (*p < 0.05; Fisher’s exact test or Chi-squared test). Nuclear swelling in the red bar graphs is 5 % or more
