FEATURES OF THE ELEMENT STATUS OF EARLY AGE CHILDREN WITH MENTAL AND PHYSICAL RETARDATION

The aim of the research was a determination of the element’s status features in children 1-3th age with mental and physical retardation. In 36th children from 1-3th age with mental and physical retardation the content of (Ca, Cu, Fe, K, Zn, Mn, S, Br, Se, Co, Cr, Cl, Ni, Mo, Sr, As, Hg, Pb) in hair was determined by a method of X-ray fluorescent spectroscopy. Hair chemical elements content was determined in1-3-year-oldchildren with mental and physical de- velopmental delay suggesting some specificchanges of elemental status. It is established that the examined children had the excess of potassium, chlorine, nickel, chromium, manganese, calcium, on the background of total deficit of zinc, copper, partially of iron and normal content of toxic elements. Excess of potassium, chlorine, nickel, chromium, manganese, calcium in accordance with this research and literature data may be a specific feature of element status at nervous disorders. However, individual assessment of the «element portrait» at diseases of the nervous system in children of early age is important to improve a treatment and rehabilitation. Comparison of the revealed features with previously collected data of healthy children and literature indicates that zinc and copper deficiency is not specific for the children with mental and physical developmental delay but is rather more significant.
