摘要
应用超脉冲ＣＯ２激光对新西兰兔进行皮肤除皱术，术后进行活体、光镜及电镜观察。结果显示，ＣＯ２激光除皱主要作用于皮肤表皮及真皮浅层，造成表皮细胞层全部或部分脱落，真皮浅层胶原纤维变性。新生的表皮皱褶变浅、减少，新生的胶原纤维富有弹性，使皮肤绷紧，去除细小皱纹。
Ultrapulse carbon dioxide laser ablations of rabbit skin were investigated. Macroscopic、microscopic and electron microscopic appearances of the ablation sites were evaluated. Results showed that the effect of laser treament was on the epidermis and the papillary dermis. All or some of the cell layers of epidermis were ablated. Degeneration took place in the papillary dermis. Wrinkles of the new epidermis were shallow and seldom. The new collagenous fibers were more elastic, which made the skin tighter and few wrinkles. Results also demonstrated that ultrapulse carbon dioxide laser stimulated hairs to grow fast.
