Irradiation with electromagnetic waves (8.15-18 GHz, 1 Hz within, 1 microW/cm²) in vivo increases the cytotoxic activity of natural killer cells of rat spleen.

In mice exposed for 24-72 h, the activity of natural killer cells increased by 130-150%, the increased level of activity persisting within 24 h after the cessation of treatment. Microwave irradiation of animals in vivo for 3.5 and 5 h, and a short exposure of splenic cells in vitro did not affect the activity of natural killer cells.
