摘要 目的探讨5-氨基酮戊酸(ALA)联合强脉冲光(IPL)的光动力学疗法(PDT)对豚鼠光老化模型的影响,并摸索合适的5-ALA治疗浓度。方法以模拟日光光源(SSR)建立豚鼠光老化模型,10%、20%5-ALA联合IPL治疗,每3周一次,共3次。观察真皮细胞外基质(胶原纤维、弹力纤维)的改变。结果豚鼠以亚红斑量SSR照射13周,光照部位真皮浅层出现了典型的光化性弹力纤维变性损害。经10%5-ALA联合IPL治疗后,上述改变明显改善,而20%5-ALA联合IPL可进一步加重损伤。结论光动力疗法对光老化有一定改善作用,选择合适的5-ALA治疗浓度很重要。 目的探讨5-氨基酮戊酸(ALA)联合强脉冲光(IPL)的光动力学疗法(PDT)对豚鼠光老化模型的影响,并摸索合适的5-ALA治疗浓度。方法以模拟日光光源(SSR)建立豚鼠光老化模型,10%、20%5-ALA联合IPL治疗,每3周一次,共3次。观察真皮细胞外基质(胶原纤维、弹力纤维)的改变。结果豚鼠以亚红斑量SSR照射13周,光照部位真皮浅层出现了典型的光化性弹力纤维变性损害。经10%5-ALA联合IPL治疗后,上述改变明显改善,而20%5-ALA联合IPL可进一步加重损伤。结论光动力疗法对光老化有一定改善作用,选择合适的5-ALA治疗浓度很重要。
