Abstract

Objectives: The purpose of this survey was to compare the amount of zinc concentration between normal children and the children suffering from Down syndrome, cerebral palsy, micro-macrocephaly, and hydrocephaly in Iran. The correlation between zinc concentration and the spoken syndromes was further assessed.

Method: In the present study, the hair sam-ples were used to estimate zinc concentration. Whereas many pathological conditions are as-sociated with alteration of scarce elements in hair, samples of both normal children and pa-tients were analyzed by atomic absorption spectrophotometery.

Findings: The patients had significantly higher level of zinc concentration in hair samples than normal children

. Results: Considering the dietary of the children in the study, this increased level of zinc could not be attributed to qualitative dietary intake. Therefore, such a high accumulation of zinc uptake could be due to the very syndromes from which the children are suffering this could lead to receiving or using cellular substances such as albumin, transferrin, or other related proteins.
