Treatment of experimental wounds in rabbits by radio‐frequency electromagnetic radiation

Twenty‐four adult rabbits of a white inbred strain were exposed ten times to sham radiation (controls) or to pulsed 14.2‐MHz electromagnetic radiation in the near field (200 μs pulses, 120 pulses s −1 ) for a 20‐minute period daily after surgical induction of a sterile wound along the dorsum of the ear. Radiation‐induced increments of ear temperature near the wound averaged 1.6°C. Median healing time of wounds in 12 controls was nine days; in 12 irradiated rabbits, six days. The augmented rate of healing is highly significant ( P < 0.005).
