The process of recovery of cell membrane damage produced by the low-level microwave radiation

Abstract

The process of cell membrane recovery after the influence of microwave radiation (f = 36.64 GHz, E = 10, 100, 400 μW/cm2, irradiation time 10 s) on human buccal epithelium cells was investigated. The stainability of cells with indigo carmine (5 mM) or trypan blue (0,5 %) after 5 min of staining was investigated. It was shown irradiation to be induced decrease of percentage of unstained cells. Recovery of cell membrane permeability after microwave irradiation was shown. Cell recovery after microwave irradiation of low intensity (10 μW/cm2) was shown after 1 h. Microwave irradiation of higher intensity (100, 400 μW/cm2) induced more strongly effects of cell membrane permeability. Cell recovery after microwave irradiation of higher intensity was shown after 3 h. For the first time recovery of cell membrane after microwave irradiation of low intensity was shown.
