Treatment of psoriasis with psoralens and high-intensity long-wave ultraviolet light (PUVA) produces changes in the ultrastructure of elastic tissue in skin. Early alterations consist of a loss of elastin followed by a breakdown of the microfibrils and subsequent fragmentation of the elastic fiber. Tissue examined 15 months after treatment was stopped still showed marked ultrastructural changes in the elastic fibers.
用补骨脂素和高强度长波紫外线(PUVA)治疗银屑病会使皮肤弹性组织的超微结构发生变化。早期改变包括弹性蛋白的丧失,随后是微原纤维的分解以及弹性纤维的碎片化。在停止治疗15个月后检查的组织中,弹性纤维仍显示出明显的超微结构变化。
