【摘要】 本文应用国产的血卟啉光敏剂(PSD-007)加不同波段的光辐照,比较了不同波段的光敏反应对癌细胞的杀伤怍用。实验结果说明,光敏药物进入细胞后,经红光、绿光和紫光等不同波段的光辐照后,均能产生光敏反应而将癌细胞杀死。不同波段的光辐照对癌细胞杀伤效应的定量研究的结果为紫光的杀伤作用>绿光>红光。作者指出:由于紫光对组织的穿透性太差,所以在实际治疗中,红光仍为治疗表浅肿瘤的最佳波段。更多还原

【Abstract】 Department of Pathological Anatomy of Second Military Medical College Photosensitive reaction of HPD and its cytotoxic action were studied, focussing on the spectral effect of the irradiating light. A human hepatocarcinoma cell line(SMMC-7721)with HPD was used. Killing effects on tumor cells after irradiation of light in three different wave-bands were observed, both qualitatively and quantitatively.Results were compared with those of Kinsey and Matsushima.更多还原
