应用光敏效应诊断和治疗恶性肿瘤是近年来国内外积极研究的新技术。把某种光敏剂注入机体,以特定波长的光波激发使之发生桔红色荧光,因而可用作定位诊断恶性肿瘤;以治疗波长的光波照射,所产生的光动力效应最终可杀死肿癌细胞,国外称之为光动力疗法(Photodynamic therapy,PDT)。国内也有称光敏疗法或光化学疗法。本文拟就近年来应用光敏效应诊治恶性肿瘤的研究概况作一简要介绍。光敏剂1924年 Policard 报道在实验性鼠肉瘤中有内源性卟啉类物质,用光激活后可见到红
The application of photosensitive effect in the diagnosis and treatment of malignant tumors is a new technology actively researched at home and abroad in recent years. A certain photosensitizer is injected into the body and excited by light waves of a specific wavelength to make it orange-red fluorescence, which can be used as a positioning diagnosis for malignant tumors; the photodynamic effects produced by treating the wavelengths of light waves can eventually kill the tumor cells. It is called photodynamic therapy (PDT) abroad. Domestic also known as phototherapy or photochemotherapy. This article intends to give a brief introduction to the recent research on the application of photosensitive effects in the diagnosis and treatment of malignant tumors. Photosensitizer 1924 Policard reports endogenous porphyrins in experimental murine sarcomas that are visible after activation with light
