| | Objective To investigate the relationship between the endothelial cell viability of the rat aortic valved homograft and the dose of 60 Co γ irradiation. Methods The rat aortic valved homografts were irradiated with 300, 600, 900 and 1200Gy 60 Co γand cryopreserved for 3 months. The pathological changes and endothelial cell viability of aortic valved homograft were observed. Results The endothelial cell viability was related to the dosage of 60 Co γ irradiation; the dose of 300 and 600 Gy i... | | 目的 研究大鼠同种带瓣主动脉内皮细胞活性与60 Coγ照射剂量之间的关系。方法 分别采用 30 0、6 0 0、90 0和 12 0 0Gy四种剂量对大鼠同种带瓣主动脉进行照射及在液氮中深低温保存三个月 ,观察不同剂量照射后同种带瓣主动脉的病理变化和内皮细胞活性。结果 大鼠同种带瓣主动脉内皮细胞活动度与照射剂量有关。在接受 30 0和6 0 0Gy照射时内皮细胞活动度分别为 (85 .6 7± 2 .5 8) %和 (83.5 5± 2 .75 ) % ,但它们与对照组相比无显著性差异 (P >0 .0 5 ) ;在接受 90 0和 12 0 0Gy照射时内皮细胞活动度分别为 (72 .2 9± 1.96 ) %和 (32 .5 7± 3.4 8) % ,它们与对照组相比有显著性差异 (P <0 .0 1)。结论 大鼠同种带瓣主动脉内皮细胞活动度与60 Coγ照射剂量有关 ,6 0 0Gy可作为参考剂量用于降低同种带瓣主动脉免疫原性的研究。 | | 文摘来源 | |   |
