title: [Effect of WS-frequence spectrum physiatrics apparatus on survival of the random flap in rats].
abstract: In this experimental study we investigated the effect of WS-frequence spectrum physiatrics apparatus on the survival of the random flap in the back of rats. The flap was radiated vertically with the WS-apparatus for 30 minutes, twice daily for 8 days. It was found that on the ninth postoperative day, the survival areas of the radiated flaps was increased significantly (P < 0.001). The isotope (99mTc) clearance, the diaphanousflap sample and SOD content were examined. The results showed that WS-apparatus can reduce the production of oxygen free radicle in the flap, increase the tolerance for ischemia and blood supply of the flap with the proliferation and vasodilation of capillary vessels.
