Abstract: 目的:观察Photofrin对小鼠光毒性的病理学改变.方法:将100只小鼠随机分为5组,其中3组为Photofrin光照组,2组为对照组.Photofrin光照组小鼠分别尾静脉注射10 mg/kg、5 mg/kg和2.5 mg/kg的Photofrin,对照组小鼠尾静脉注射5%葡萄糖注射液,模拟日光照射,分别于给药后24 h和第15天对背部去毛区、耳朵、尾巴皮肤,肝脏、肾脏等进行病理组织学检查.结果:Photofrin光照组小鼠耳朵皮肤可见明显的鳞状上皮增生,其中Photofrin10 mg/kg光照组背部去毛区皮肤表面可见鳞状上皮乳头状增生、炎细胞聚集.结论:Photofrin能增强小鼠皮肤光毒性的损伤.
