Effect of electrostatic fields on the chromosomes of Ehrlich ascites tumor cells exposed in vivo.

An effect of electrostatic fields on the chromosomes of Ehrlich ascites tumor cells exposed in vivo has been demonstrated. Cells exposed to horizontal electrostatic fields for two weeks had almost a threefold increase in the percentage of abnormal chromosomes when compared to control cells or cells exposed to vertical electrostatic fields for the same period. Extended exposure times of 4--15 weeks resulted in the disappearance of the aberrant chromosomes. It is suggested that the effected cells were incapable of cellular replication resulting eventually in their disappearance via cell death.
