cell nucleus, heterochromatin, microwave radiation


The effect of low energy electromagnetic radiation with frequencies 1.8 GHz and 2.4 GHz on the heterochromatin granules quantity (HGQ) in the nuclei of human buccal epithelium cells was studied. Exfoliated cells were exposed to microwave radiation (frequency 1.8 GHz, surface power density 2.5 μW/cm2; and also frequency 2.4 GHZ, surface power density 2.3 μW/cm2). After exposure to microwaves during 1, 2, and 3 h, immediately or after delay of 1 or 2 h cells were stained with orcein (2% solution in 45% acetic acid). Cell exposure to microwaves induced condensation of chromatin. The biological and medical meanings of the data obtained are discussed.
