血卟啉衍生物(HPD)-激光治疗肿瘤已取得较好的临床效果.其机理可能涉及活性氧(~1O2)和脂质过氧化反应对癌细胞的损伤.我们认为,如果使癌细胞抗活性氧和脂质过氧化损伤的能力降低,则可提高疗效.DDC(二乙氨基二硫代甲酸钠)可使超氧化物歧化酶和谷胱甘肽过氧化物酶的活力降低,从而可使癌细胞抗活性氧和脂质过氧化损伤的能力降
Hematoporphyrin derivative (HPD)-laser treatment of tumors has achieved good clinical results. The mechanism may involve reactive oxygen species (~1O2) and lipid peroxidation on cancer cells. We believe that if we make cancer cells resistant Reduced ability of reactive oxygen species and lipid peroxidation damage can improve the efficacy. DDC (sodium diethyldithiocarbamate) can reduce the activity of superoxide dismutase and glutathione peroxidase, which can make The ability of cancer cells to resist reactive oxygen species and lipid peroxidation
