摘 要：Nowadays CO2 laser has been regarded as the effective treatment methods of different kinds of cosmetology and dermatologic surgery. The second-degree scald is of frequent occurrence in people, but many methods on treat the second-degree scald are not good enough. Therefore, the process of second degree scald skin irradiated by the CO2 laser was monitored in the study. The second-degree scald of mice models were divided into two groups in order to contrastively observe the effect of CO2 laser on treating scald. Skin detector associating with the histopathologic examination were used to observe the changes of skin texture and pathologic morphology structure. Meanwhile the healing time was recorded about the two groups. The texture of skin surface irradiated CO2 laser was more glossy and distinct after healing, and the healing time was much faster as well. It was good agreement between skin detector images and histopathological architecture.
