Primary source abstract: "Research methods and procedures: Total body potassium (TBK) model: BCM from TBK by whole-body counting-ECF(TBK)=LST-[BCM(TBK)+0.73 x osseous mineral (Mo)]. Bromide model: ECF from sodium bromide dilution-BCM(BROMIDE)=LST-(ECF(BROMIDE)+0.73xMo) Mo and LST measurements came from DXA. The two approaches were evaluated in 99 healthy men and 118 women." BCM=body cell mass, ECF=extracellular fluid, LST=lean soft tissue, DXA=Dual-energy X-ray absorptiometry |
| Comments |
P.8 2nd paragraph: "Mass-Centered Approach as Sanity Check for Cell Count: It is prudent in making such estimates to approach the analysis from different angles. In that
spirit, [investigators] now ask does the cumulative mass of the cells counted fall within the expected range
for a reference adult? To properly tackle that question, [they] first need to state what the anticipated
result is, i.e., total body cell mass. For a reference man mass of 70 kg, 25% is extracellular fluid [primary source], another 7% is extracellular solids [primary source], thus [they] need to account for ≈46 kg of cell
mass (including fat)." |
