中文摘要:
      实验中用Beagle狗10只,以0.0247~0.0278C·kg-1·min-1照射量率,全身照射6.5Gy,分3组:第1组3只,作为对照,不给任何治疗,照射后全部死亡,平均活存7.5天。第2组4只,移植性别相反的同种血造血干细胞。供受体混合淋巴细胞培养刺激指数小于0.69,红细胞交叉凝集试验阴性,未在体外去除供体血细胞中的T淋巴细胞。结果表明,照射后11,20和26天检查性染色体,均为供体核型。4只狗死于严重GVHD,平均活存41.6天。第3组3只,移植去除T淋巴细胞的同种血干细胞,2只死亡,1只发生轻度GVHD,长期活存4年以上。
英文摘要:
      In the study,10 beagles were used. All the dogs were irradiated with 6.5 Gy of γ-rays from a 60Co source(dose rate,95.6-107.9 R/min) and divided into three groups.All the three dogs in the control group died,having survived 7.5 days on the average after irradiation.In the second group,four dogs were transplanted with allogeneic peripheral blood hemopoietic stem cells(PBHSC) without removing T lymphocytes.The results of sex chromosome tests after irradiation and transplantation showed that the cells were of donor type.All the four dogs died of severe graft-versus-host disease(GVHD) and survived 41.6 days on the average after irradiation.In the third group, three dogs received transplantation of allogeneic PBHSC without T lymphocytes.Two of them died,and the third developed mild GVHD and survived over 4 years.
