提高乏氧细胞的放射敏感性是肿瘤放疗临床上亟待解决的一大课题,而天然生物活性物质-保尔佳的应用,可能会成为我国放射生物及肿瘤临床研究的重要方面,为观察保尔佳对肺癌的放射增敏作用,我科于1995年8月～1996年7月收治中晚期肺癌31例,将患者随机分为保尔佳+放射治疗组(综合组) Increasing the radiosensitivity of hypoxic cells is a major issue to be solved urgently in tumor radiotherapy. However, the application of natural biologically active substance, Paul Bioscience, may become an important aspect of the clinical research on radiobiology and oncology in our country. Good radiosensitizing effect on lung cancer, our department in August 1995 ~ July 1996 admitted to advanced lung cancer in 31 cases, the patients were randomly divided into Paul Jia + radiotherapy group (integrated group)
