title: [The analysis of the influencing factors of mortality rate in the transplantation of mouse bone marrow].
abstract: The purpose of the study was to investigate the influencing factors of mortality rate in the bone marrow transplantation in mice. The recipient mice receiving whole-body irradiation of gamma-ray were infused with the same strain of bone marrow cells or the mixture of the bone marrow cells and splenocytes respectively. Experiments were carried out in four batches, with different strains of mice used, respectively. The manifestations and the appearance of graft-versus-host disease (GVHD) were observed, as well as the mortality rate within 35 d of the transplantation in the recipient mice. The mortality rate of the first group of recipient mice was the lowest, the mortality rate of the second group of recipient mice was the highest and the obvious GVHD performance was observed before death. In the third group, the mortality rate declined and there was statistical significance compared to that of the second group. The mortality rate of the fourth group of mice was higher than that of the third group, but still lower than that of the second group of mice and there is a statistical significance. This evidence suggested that mouse genetic purity, splenocytes, the ratio of the bone marrow cells and splenocytes and the week-old of the mouse could be the important influencing factors of the mortality rate in mouse bone marrow transplantation.
