Cytogenotoxicity of BSH alone.

	Plating efficiency	Baseline CA frequency
No BSH	0.58 ± 0.02	0.027 ± 0.003
40 ppm 11B	0.61 ± 0.04	0.027 ± 0.003
80 ppm 11B	0.60 ± 0.04	0.023 ± 0.003

Plating efficiency (PE) values and total chromosome aberration (CA) yields in unirradiated DU145 prostate cancer cells (second column) and normal epithelial MCF-10A cells (third column), respectively, as a function of the amount of BSH. By definition, PE measures the survival of cells in the absence of radiation. Similarly, the recorded frequency of CAs in cells not exposed to radiation is referred to as baseline CA frequency. Data show lack of BSH-induced cyto- and genotoxicity at the used concentration.
