title: [Cytological and karyological modifications of HeLa cells induced by periodic changes of extracellular potassium levels].
abstract: The effects of periodic changes in the external potassium concentration on chromosome structure and morphology of HeLa cells are reported. The observed cellular modifications seem to be directly related to changes in the ratio of external to internal potassium levels.
