一、光化学疗法治疗恶性肿瘤近几年来,在抗癌领域中,兴起了一种新的治疗肿瘤的方法——光照疗法(Photodynamic therapy简称PDT)。光照疗法系根据光敏原理,故称光敏疗法或光化学疗法,由于光源为激光,光敏剂为血卟啉衍生物(Hematoporphyrin Derivative,HPD),习惯称为;激光——血卟啉疗法,简称HPD-PDT。早在1900年Raab发现染料吖啶橙(Acridine orange)被草履虫吸收后失去活力,避光者即生存,称为光敏现象。其后相继证明,
First, photochemotherapy for malignant tumors In recent years, in the field of anti-cancer, a new method of treating tumors has emerged - photodynamic therapy (PDT). Light therapy is based on the principle of light-sensitive, so called phototherapy or photochemotherapy, because the light source is laser, photosensitizer is hematoporphyrin derivative (HPD), used to be called; laser - hematoporphyrin therapy, referred to as HPD- PDT. As early as 1900, Raab discovered that the dye Acridine orange was lost after being absorbed by paramecium, and the light-repellent person survived and was called light-sensitive phenomenon. After successively proved,
