本文观察到癌光啉加红光对人肝癌细胞裸鼠移植瘤有杀伤效应,随处理后时间的延长,杀伤效应更趋明显。早期,癌肿细胞内线粒体、粗面内质网肿胀,细胞颗粒变性,间质血管充血;晚期,线粒体、粗面 In this article, we observed that the addition of carboline plus red light has a killing effect on human hepatocellular carcinoma xenografts in nude mice. With the prolonged treatment time, the killing effect becomes more obvious.
