Wound healing of rat skin may be arbitrarilydivided into the following stages: wound generation, suppurating in someinflammation area, growing of granulation tissue, scab formation,decrustation, and completely healing. The wound depth and the extent ofhealing also could be determined from the OCT images in the different healingtime. Healing time for the skin scald was found to be much shorter than those ofthe skin wound. Because the skin wound is serious than the skin scalds. 3 The result of using OCT to monitor the model of acetic acid gastric ulcer in rats:Results of this experiment showed that using OCT technology can identify theulcerative gastric mucosa tissues with normal tissues, make the imaging on theunder-layer of gastric mucosa tissues, and evaluate the healing period and healingquality.
