【摘要】 研究了单次和两次X射线辐照对人皮肤成纤维细胞GM5 75 8的存活和分化影响。结果表明 :两次照射的细胞存活率比单次照射的细胞存活率有明显的提高 ;单次照射引起的细胞分化百分比比两次照射的细胞分化百分比要高。提示分次照射有利于放射治疗中正常皮肤组织的保护。更多还原

【Abstract】 The effect on survival and differentiation of human fibroblast GM5758 induce by one and two fractional X-ray irradiation was studied. The results show that the survival fraction of two-fractional irradiation is higher than the survival fraction of one-fractional irradiation. The differentiation fraction of one-fractional irradiation is higher than that of two-fractional irradiation. This suggests that fractional irradiation protects the healthy tissue during radiotherapy.更多还原
