Optical coherence tomography (OCT) is powerful tool for in vivo tomographic imaging of the internal microstructure in biological tissue. In this study, we prepared the animal model of genuine pig with allergic dermatitis developed by chemical administration to examining their skin inflammation by microscopic observations with OCT images captured continuously, aiming at tracking the morphological changes in the skin structure induced by the chronological inflammation. As a result, epidermis thickening became evident as the days passed since Day 7, and the capillary vessel expansion was confirmed since Day 14;the process of inflammation development was successfully observed.展开更多
