摘要: 目的: 研究125I密封籽源对Hela细胞的杀伤作用以及对肿瘤的抑制作用。方法: 通过内植入法将125I密封籽源植入荷瘤鼠的肿瘤内,观察其对肿瘤的抑制作用以及血液学毒性。结论: 125I密封籽源对Hela细胞杀伤明显,照射48h的杀伤范围为1.6~2.4mm,对肿瘤有明显的抑制作用,对血象和生化指标无明显影响。结论: 125I密封籽源组织植入治疗法能有效抑制肿瘤的生长。并达到了治疗的效果。Abstract: Objective: To investigate antipersonnel effectiveness of Hela cell and therapeutic effectiveness of tumor of 125I sealed seed source. Method: 125I sealed seed source was implanted in tumor of bearingtumor mice, therapeutic effectiveness of tumor and toxicity of blood were observed. Result: 125I sealed seed source had antipersonnel effectiveness for Hela cell, and the range of antipersonnel effectiveness was 1.6~2.4mm after 48h irradiation, and controlled patently the growth of tumor, toxicity of blood was not found. Conclusion: 125I sealed seed source could control effectively the growth of tumor and obtain therapeutic purpose.
