[Analytical methods for measuring the content of trace elements in children with chronic gastrointestinal diseases]

Plasma trace elements (TE) were determined by atomic absorption spectrometry with electrothermal atomization and by mass spectrometry with inductively bound plasma. These techniques are highly effective and may be used to determine TE in biological samples. In children, chronic gastrointestinal diseases are accompanied by mineral metabolic disorders. In children with chronic gastrointestinal diseases whose age was 6 to 15 years and whose weight was varying, the scores of some TEs depend on a child's body weight and may be used to evaluate the degree of a pathological process.
