作者于2010年中国医科大学研修期间,在放疗科实验室以体外培养的人肺腺癌细胞株A549为靶细胞,以盖诺为诱导剂,采用体外药物敏感性试验的MTT比色方法,研究盖诺对于离体肿瘤细胞的放疗增敏作用,探索是否能够增加放疗敏感性,为临床提供相关依据。1材料与方法1.1药物与细胞人肺腺癌细胞株A549在含有10%小牛血清,青链霉素各100U/ml的合成培养液RPM 1640中,在 During the training of China Medical University in 2010, the human lung adenocarcinoma cell line A549 cultured in vitro was treated as a target cell in radiotherapy laboratory, with Gynol as the inducer and MTT colorimetric method of in vitro drug sensitivity test Gynoeos radiosensitization of tumor cells in vitro to explore whether it can increase the sensitivity of radiotherapy for the clinical basis. 1 Materials and methods 1.1 Drugs and cells Human lung adenocarcinoma cell line A549 In a synthetic medium RPM 1640 containing 10% calf serum and 100 ml streptomycin,
