Aim of study (acc. to author)

To investigate the influence of microwave irradiation on electrophoretic properties and chromatin condensation in interphase cell nuclei. Furthermore the integrity of the cell membrane was studied.

Main outcome of study (acc. to author)

The microwave irradiation induced an increase in chromatin condensation and a decrease in the electrical charge of cell nuclei. The membrane integrity was not affected. However, these effects depend on individual donor specific peculiarities.
