一、血卟啉-激光治疗癌肿的基本原理: 血卟啉-激光光化疗法,是近年来国内外新开展的癌肿诊断、治疗的一种最新技术。血卟啉又叫血紫质,是构成红细胞中血红蛋白的一种成份。血卟啉是一种光敏物质,受光照射后,产生可以杀死癌细胞的光化学反应。血卟啉有两个特点:①与癌细胞的亲合力很强,可以选择性地聚集在癌细胞里,达到较高的浓度,这浓度比正常细胞高10倍。②在某
First, the basic principles of hematoporphyrin-laser treatment of cancer: Hematoporphyrin-laser photochemotherapy is a new technology for the diagnosis and treatment of cancer newly developed at home and abroad in recent years. Hematoporphyrin, also called hemochromatosis, is a component of hemoglobin in red blood cells. Hematoporphyrin is a light-sensitive substance that, upon exposure to light, produces a photochemical reaction that kills cancer cells. Hematoporphyrin has two characteristics: 1 It has strong affinity with cancer cells and can selectively accumulate in cancer cells to a higher concentration, which is 10 times higher than normal cells. 2 in some
