Comparison of Bone/Blood-Associated Radioactivity in Control and Thrombocytopenic Mice

CD-1 Mice W/B F1
Control (n = 8) Irradiated (n = 5)1 d RAMPS (n = 6) 5 d RAMPS (n = 6) Male (n = 6) Female Control (n = 3)
Femur  15.7 ± 3.4 9.6 ± 1.5* 25.5 ± 3.1 26.3 ± 6.1 22.3 ± 7.0  13.8 ± 2.3  
Sternum  13.1 ± 3.9 10.4 ± 3.1  22.1 ± 2.3 23.1 ± 3.3 22.2 ± 7.7  13.7 ± 1.5 
CD-1 Mice W/B F1
Control (n = 8) Irradiated (n = 5)1 d RAMPS (n = 6) 5 d RAMPS (n = 6) Male (n = 6) Female Control (n = 3)
Femur  15.7 ± 3.4 9.6 ± 1.5* 25.5 ± 3.1 26.3 ± 6.1 22.3 ± 7.0  13.8 ± 2.3  
Sternum  13.1 ± 3.9 10.4 ± 3.1  22.1 ± 2.3 23.1 ± 3.3 22.2 ± 7.7  13.7 ± 1.5 

Femur and sternum associated radioactivity is expressed as the percentage of whole blood-associated radioactivity (cpm per gram of tissue/cpm per mL blood × 100%, mean ± SD).
