前言在1982年我们曾对L_(615)小鼠白血病模型进行了血液学,细胞遗传学,免疫学以及细胞DVA合成功能等方面的系统观察,此后,又研究了小鼠在受不同中等剂量照射,及移植小鼠白血病病株的复合作用下,小鼠的生物学特性,试图通过这些实验的观察,了解电离辐射(100—700拉德)在小鼠发病过程中的作用,进而探讨白血病发生与电离辐射的关系。实验结果表明:在小鼠受到复合作用后,病情加重,病程缩短, Introduction In 1982, we performed systematic observations of hematology, cytogenetics, immunology, and cellular DVA synthesis in the L_(615) mouse leukemia model. After that, we also studied mice exposed to different doses of moderate doses. The effects of ionizing radiation (100-700 rads) on the pathogenesis of mice and the investigation of the biological characteristics of mice under the combined effects of transplanted murine leukemia strains were investigated. The relationship with ionizing radiation. The experimental results showed that after the mice were subjected to a complex effect, the condition became worse and the course of the disease was shortened.
