the analysis of mitotic indices ( mi ) and chromosome breakages in metaphases of 50-hr lymphocyte cultures exposed to the calcium or zinc chelates of diethylenetriamine pentaacetic acid ( dtpa ) demonstrated : ( 1 ) an 80 % reduction in mi in cultures from three women but no reduction in those from two men after in vitro exposure to cadtpa in concentrations as low as 10 micrograms/ml culture medium , and complete suppression of mitoses in cultures from men and women after exposure to 40 micrograms/ml cadtpa ;
