    Abstract:
    OBJECTIVE: To investigate the biodistribution of 131I-GM-CSF in SCID mice bearing human AML in vivo. METHODS: The xenograft model of human leukemia was established in SCID mice. In the leukemia mice, the biodistribution of 131I-GM-CSF produced by chlo amine-T method was studied. RESULTS: (1)The inoculated HL-60 cells could grow in SCID mice, which developed leukemia after 4 weeks. (2) 131 I-GM-CSF was concentrated in spleen, bone marrow and tumor tissue of the mice. In spleen and bone marrow, 131 I-GM-CSF was uptaken to peak in 30 minutes after injection, the up taking rate was (442. 9+/-86. 4) % ID/g and (4283. 8+/-252. 8)% ID/g, respectively, and maintained on higher level in 24 hours. The injection of 131I resulted in an even distribution in the whole body. CONCLUSIONS: 131 I-GM-CSF is able to concentrate electively in spleen, bone marrow and organs infiltrated by leukemia cells. The biodistribution of 131I-GM-CSF in the leukemia mice is tissue specific.
