Very few publications have quoted differences between the same regions in both the right and left hemispheres of the human brain. It may be possible that that the two hemispheres have different trace elemental concentrations, since it is known that they both have different functions. In this study, three brain regions from both the right and left hemispheres of the cortex have been sampled from five elderly individuals (three 'normal' and two Alzheimer's disease) and their elemental concentrations have been determined by instrumental neutron activation analysis (INAA). 相似文献

Severe analytical problems are associated with the analysis of heavy metals at very low levels in biological samples. This
impose a high degree of sophistication of the NAA involving treatment of the sample before irradiation such as chemical separations,
physical treatments and biochemical fractionation, the experimental evaluation of interfering nuclear reaction as well as
the development of post-irradiation radiochemical separation. This paper treats of the problem related to the NAA of trace
elements in environmental biochemical toxicology focussing attention of the sources of the elements during the analysis. Typical
results and short discussion for every step of the analysis are reported. 相似文献

Neutron activation analysis (NAA) has been used for thedetermination of 26–31 elements in lung, urine, blood and nails of a photoengraver professionally exposed to cored arc light carbon fumes doped with cerium as well as a control group. The results show a clearly abnormal presence of rare earths in the lung of the worker. An evaluation was made of possible contamination during the sampling. 相似文献
