Trace element concentration in human organs in dependence of age

摘要: Abstract There is evidence from epidemiological studies that concentration of various trace elements in human organism not only changed by different diseases but also the environment. Interpretation such data requires definition normal organs. Material and Methods In 21 patients aged o to 83 years, skin, lung, heart, liver, renal medulla, cortex, aorta abdominalis, brain were assayed. All samples dried at 100° C for two days. Instrumental neutron activation analysis was used determine element Co, Fe, Zn, Rb, Se, Cr, Sb, Sc, Cs. Results The behaviour several uniform concentrations all decreased skin apart non-essential content essential increased liver kidneys after first year age. aorta, brain. Cs raised nearly organs except with progressing age; Sb showed a slight decrease heart aorta. Apart Co Fe life. Rb varied organ organ. Discussion indicate are no fixed values. However, they depend on factors. some has regard its function alterations varying subject control mechanisms consequence simple storage, whereas increasing age should be explained storage mechanism.
