ABSTRACT
In more than ten years, hematopoietic factors have been approved to be effective in the treatment of radiation sickness. But there are still some problems in the clinical application, such as suitable cases, dosage, administrative timing, and drug combination. Due to those problems, the efficacy was undermined. Our experimental treatment study showed that hematopoietic factors should be administered early after the radiation exposure. The efficacy of early administration group is better than the one treated in acute phase of radiation sickness. There is also a limit of application duration but not the longer the better. RhTPO along can not induce the granulocytopoiesis and rhG-CSF can not improve the recovery of megakaryopoiesis. Hematopoietic factors do not increase the chromosome mutation rate of tumor cells. We did not observe bone marrow stem cell or progenitor cell exhaustion after we treated those animals for a second cycle of hematopoietic factors or exposed those treated animals to radiation again. RhG-CSF is more effective in the recovery of granulocytopoiesis than rhGM-CSF. RhIL-11 can increase the recovery of three cell lines of bone marrow, especially megakaryopoiesis. We recommended the combination of hematopoietic factors in the treatment of acute radiation sickness. RhG-CSF plus rhIL-11 is a preferred combination.
