원저 : 무모생쥐 피부에 1320 nm Nd:YAG 레이저와 long-pulsed 1064 nm Nd:YAG 레이저의 조사 효과

Background: The treatment of facial rhytides has traditionally centered around methods that involve removal of the epidermis and superficial dermis, encouraging the production of a new epidermis with collagenesis and remodelling. But all of the resurfacing techniques lead to postoperative complications such as oozing, bleeding, infections, "downtime" as the skin begins to reepithelialize, and the occasional incidence of posttreatment, postinflammatory pigmentary changes. 1320㎚ and 1064㎚ wavelengths are nonspecifically absorbed in the human dermis and are unique for its significant horizontal scattering. These wavelengths, when used for localized facial areas, have been shown to produce new collagen formation and improvement in the quality of treated skin. Objective: The purpose of this study was to examine the effect of 1320㎚ Nd:YAG laser and long-pulsed 1064㎚ Nd:YAG laser irradiation on hairless mouse skin and rat skin. Methode: In this study, the effect of 1320㎚ Nd:YAG laser and long-pulsed 1064㎚ Nd:YAG laser irradiation were examined by Hematoxylin and eosin (HE42(4):385~391)
