We studied the effects of EHF EMR on the dynamics of contraction of wound surface during
posttraumatic regeneration of the skin on mouse back. Wound process was simulated in the inter-
scapular region of mice by excising skin ap area of about 70mm

with a damaged underlying fas-
cia and muscle layer under ether anesthesia. The dynamics of the healing process was determined
by the change in the area of the wound defect, which is daily photographed with a digital camera
Nikon Coolpix 990 (Japan). After applying the full-thickness skin wounds, mice were exposed to
EHF EMR (42.2 GHz, 0.1 mW/cm
