激光治疗对从癌、心脏病和脑血管等严重疾病到疣和痣的治疗效果正在提高。日本大宫市七里医院装备二氧化碳激光、氩激光、钕YAG激光和氩色素激光,4年间共做大小手术750例。用化学反应消灭癌迄今激光的治疗多用二氧化碳激光切开组织,或用YAG激光凝固等方法,是利用热的作用。然而,东京大学尖端技术研究中心藤正严教授指出,这只不过是代替电和其他方法,并未发挥激光本来的作用。在这个意义上,现在最引人注目的是利用激光的化学反应来消灭癌细胞,即光力学治疗法(PDT)。具体的方法就是首先给患者静脉注射与血液中血红蛋白相似的血卟啉诱导体。投药量是每公斤体重2～5mg。这种物质具有一种不同特性,它容易集中于
Laser treatment is improving the treatment of serious diseases such as cancer, heart disease and cerebrovascular diseases to hernias and hernias. The Seven Mile Hospital in Omiya City, Japan, was equipped with a CO2 laser, an Argon laser, a YAG laser, and an Argon dye laser. A total of 750 cases of surgery were performed in 4 years. The elimination of cancer by a chemical reaction The treatment of lasers has heretofore been performed using a carbon dioxide laser to cut tissue, or by YAG laser coagulation, etc., which utilizes heat. However, Professor Teng Zhengyan of the Center for Advanced Technology Research at the University of Tokyo pointed out that this is only an alternative to electricity and other methods and does not play the role of lasers. In this sense, what is most noticeable now is the use of laser chemical reactions to destroy cancer cells, photodynamic therapy (PDT). The specific method is to first intravenously inject the hematoporphyrin inducer similar to hemoglobin in the blood to the patient. The dosage is 2-5 mg/kg body weight. This substance has a different characteristic, it is easy to focus on
