The implantation experiments correlate well with the observations for skeletal development under the three dietary conditions. The osteopenia observed in the rats raised for 12 months on the L or D diets could be a manifestation of a disequilibrium between the rates of osteoclastic and osteoblastic activity. Both of these cellular activities are influenced by the trace element status of the animal. If the osteoblastic activity were more strongly inhibited by...

Although requirements for vitamins and trace elements are known in health (Table 30-1), the effects of illness on these requirements are poorly understood and quantified. However, it is now apparent that as an individual develops progressively more severe depletion in vitamin or trace element status, the person passes through a series of stages with biochemical or physiological consequences. The metabolic or physiological penalty of such suboptimal nutritional status is usually not clear, but the assumption remains that the suboptimal metabolism is likely to have detrimental effects (e.g., subclinical deficiency of folic acid is associated with an increase in serum homocysteine concentration, which is an independent risk factor for coronary artery disease—see Chapter 26). Similarly, subclinical deficiency of chromium may be associated with impaired glucose tolerance in certain types of diabetes. 

In all supplementation therapy it is prudent to assess the trace element status of the patient, by monitoring the blood plasma. For example, for iron the haematinic index can yield useful information that can be used to monitor the success of the treatment. However, simple measurement of the concentrations of the relevant metals in blood plasma is not necessarily the most useful indicator of the effectiveness of supplementation therapy, since the total concentration of metal in the plasma may not reflect the concentration of the particular metal species that is required to counteract the deficiency state.

In the bio-medical field, the main analytical interest is focused on the well known essential trace elements Co, Cr, Cu, F, Fe, J, Mn, Mo, Ni, Se, Si, Sn, V and Zn in all kinds of tissues and body fluids for clearing up the role and the function of trace elements in the living organism. For some few cases trace element status is used for diagnosis and therapy control of diseases recognized as a malfunction of trace element metabolism. This field of application has a continuously increasing importance due to the increase in the knowledge in this field, for which the development of adequate analytical techniques is the most important factor. 

Whole Blood has in practice no significance for diagnosis and for therapeutic monitoring using the trace element status. Exceptions are trace elements which have a special bounding to the erythrocytes, e.g. Cd and Pb, but the concentrations present are too low for ICP-AES. Besides, in most cases a mineralization or digestion of the whole blood sample is necessary, because it is not possible to introduce it into a normal pneumatic nebulizer. 

In this connection one must point out the importance of multi-element analysis in serum for diagnostic purposes. The determination of a singie trace eiement gives no evidence about the relative abundance of this element, because many factors influence the "normal" actual trace element status stress situations, nutrition etc. The trace elements are mostly bound to proteins and therefore it should be standardized to the total protein content (Fig. 16). In practice, the phosphorus concentration in serum is a sufficient...

Jenkins and Davies (1966) showed a close correlation between metal amounts in lichen ashes of Lecanora gangaloides and Parmelia omphalodes and those in the ash of material deposited from the atmosphere. Their results are based on a detailed statistical examination of the analytical data provided in part from an investigation on the role of saxicolous lichens in the initial stages of pedogenesis and in part from a routine survey of the trace element status of 127 mountain top soils. The concentrations of individual elements in a particular lichen species tended to converge to a preferred value. Their conclusion was that some constant factor apparently domi-...
