The alteration of concentration of essential microelements in blood plasma in children with chronic diseases of gastrointestinal tract and having different body mass

: The article deals with the characteristics of alterations of mineral metabolism indicators in children of various age with chronic diseases ofgastrointestinal tract and having body mass of normal and different surplus degrees. The sample consisted of 127 children aged from 6 to 15 years with chronic gastroduodenitis, pancreatitis and cholecystitis. The concentration of bioelements in plasma was determined using the technique of mass spectrometry with inductively coupled plasma. The study established the increase of concentration of molybdenum 4.3 times, chrome--8.4 times and selenium--1.36 times. The revealed bioelemental misbalance impacts the overall health of children and course of disease and hence has to be accounted in case of application of treatment targeted to the correction of mineral metabolism.
