摘要: In vivo neutron activation analysis (NAA) is currently used to measure body composition in metabolic and nutritional studies many clinical situations, but has not previously been validated by comparison with chemical of human cadavers. Total nitrogen (TBN) chlorine (TBCl) were measured two cadavers NAA before homogenization (CHEM) after (cadaver 1: TBN, 1.47 NAA, 1.51 CHEM; TBCl, 0.144 0.147 cadaver 2: 0.576 0.572 0.0227 0.0250 CHEM). The homogenates also analyzed no significant differences found, indicating that the effects elemental inhomogeneity on measurement TBN TBCl are insignificant. water, fat, protein, minerals, carbohydrates chemically for each compared estimates these compartments obtained from a model, which when involves tritium dilution. agreement found justifies use model changes total fat sequential groups patients.
